FIELD OF THE INVENTION
The present invention relates to a skin care composition and, more
particularly, to a skin cleansing, protecting, moisturizing, firming, conditioning,
occlusive barrier, and emolliency composition.
BACKGROUND OF THE INVENTION
In recent years, body washes were not only expected to cleanse the body
but also to provide conditioning characteristics. It is well known in the personal
care industry to formulate products that provide both cleansing and moisturizing
benefits. Many polysaccharides are used as rheology modifiers for skin care
products. Cellulose ethers and polygalactomannan and polygalactomannan
derivative products are among the best known polysaccharides for use as
rheology modifiers.
Cationically derivatized cellulosics and polygalactomannan derivatives are
used as a conditioning agent for hair and skin. Cellulosics and
polygalactomannan polymers without a cationic group(s) are not used as
conditioning agents but rather are used only as a rheology modifier. Most of the
commercial cationic polygalactomannans, such as cationic guar produces, have
cationic degree of substitution (DS) of less than 0.20. Because of
manufacturing process related issues* only cationic guar with DS of less than 0.2
is commercially available from raw material suppliers, such as Hercules
Incorporated that markets its products under the trademark N-Hance® and
Rhodia Corporation that markets its products under the trademarks Jaguar® and
Excel®. It is also know in the personal care industry that levels of cationic DS on
a polygalactomannan do affect performance of cationic guar in skin care
compositions, such as body cleansing and conditioning. The higher the cationic
DS, the better the conditioning effect is expected to be at the same use level of
the low DS cationic guar. In addition, because of the low DS of the commercial
polymers, they are less soluble in water and, therefore, also impact viscosity of
the body washes significantly if attempts are made to use higher levels. There
are several prior art references that disclose the use of cationic
polgalactomannans in personal care products.

US Patent Application publication 2003/0215522 A1 discloses a personal
care composition and a zinc anti-dandruff agent and a cationic polymer.
Notwithstanding the prior art, a need still exists in the marketplace for skin
care compositions containing cationic polygalactomannans wherein the
composition provides better protection to the skin and has significantly improved
stability as compared to similar prior art compositions.

DETAILED DESCRIPTION OF THE INVENTION
It has been surprisingly found that the using of cationic guar polymers
having a DS > 0.2 provided to skin care products improved protection and
greater stability for longer shelf life as compared to similar prior art products.
These polymers are significantly lower in aqueous viscosity as compared to
cationic guar polymers with DS Aqualon Co.) and Jaguar products (marketed by Rhodia Corp.). Because of the
higher DS and lower viscosity that the polymers of the present invention have,
they can be used at much higher levels in skin care formulations such as body
wash in order to provide skin conditioning and moisturizing. In addition, they
provide better salt tolerance than the counterpart guar products with low DS.
Other applications for the cationic guar polymers of the present invention are
skin and sun care lotions, liquid and bar soaps.
In accordance with the present invention, the cationic guar polymers
provide flexibility to work in alkaline pH environment because they have no borax
which is commonly used in current commercial cationic guar. In alkaline pH
environments, guar polymers cross-link with boron ion and causes it to thicken
and even form a gel-like network which is difficult to dispense through
packaging material commonly found for body wash and other skin care products
In accordance with the invention, the polymers that can be used in the
invention include cationic galactomannan polymers or cationic derivatized
galactomannan polymers having a weight average molecular weight (Mw) having
a lower limit of 2,000, preferably 10,000, preferably 50,000, more preferably
100,000, and even more preferably 400,000. The upper limit of the Mw of these
polymers are 10,000,000, preferably 5,000,000, more preferably 2,000,000, and
even more preferably 1,000,000. Examples of the polygalactomannans of this
invention are guar, locust bean, honey locus, and flame tree with guar gum being
the preferred source of the polygalactomannan. The preferred
polygalactomannan starting material used in this invention is guar flour, guar
powder, guar flakes, guar gum, or guar splits which have been derivatized with a
cationic substituent.
The preferred polymers of this invention are cationic polygalactomannan
polymers. The amount of cationic functionality on the polygalactomannan can
be expressed in terms of moles of substituent. The term "degree of substitution"
as used in this invention is equivalent to the molar substitution, the average
number of moles of functional groups per anhydro sugar unit in the
polygalactomannan gum. The cationic functionality can be present on these
polymers at a DS lower limit amount of 0.25, preferably about 0.4, and more
preferably 0.8. The DS upper limit is normally about 3.0, preferably about 2.0,
and more preferably 1.0.
The cationic functionality of the polygalactomannan or derivatized
polygalactomannan can be added to them by several methods. For example,
the starting material can be reacted for a sufficient time and at a sufficient
temperature with tertiary amino compound or quaternary ammonium compound
containing groups capable of reacting with the reactive hydrogen ions present on
the polygalactomannan or derivatized polygalactomannan in order to add the
cationic functionality to the starting material. The sufficient time depends on the
ingredients in the reaction mass and the temperature under which the reaction is
taking place.
The cationizing agent otthe present invention is defined as a compound
which, by substitution reaction with the hydroxy groups of the
polygalactomannan can make the product electrically positive, and there is no
limitation to its types. Tertiary amino compounds or various quaternary
ammonium compounds containing groups capable of reacting with reactive
hydrogen present on the polysaccharide, can be used, such as 2-
dialkylaminoethyl chloride and quaternary ammonium compounds such as
chloro-2-hydroxypropyltrimethylammonium chloride, and 2,3-epoxypropyltrimethylammonium
chloride. Preferred examples include
glycidyltrialkylammonium salts and 3-halo-2-hydroxypropyltrialkylammonium
salts such as glycidyltrimethylammonium chloride, glycidyltriethylammonium
chloride, gylcidyltripropylammonium chloride, glycidylethyldimethylammonium
chloride, glycidyldiethylmethylammonium chloride, and their corresponding
bromides and iodides; 3-chloro-2-hydroxypropyltrimethylammonium chloride, 3-
chloro-2-hydroxypropyltriethylammonium chloride, 3-chloro-2-
hydroxypropyltripropylammonium chloride, 3-chloro-2-
hydroxypropylethyldimethylammonium chloride, and their corresponding
bromides and iodides; and quaternary ammonium compounds such as halides
of imidazoline ring containing compounds.
Other derivatization of the catlonic polygalactomannan with nonionic
substituents, i.e., hydroxyalkyl wherein the alkyl represents a straight or
branched hydrocarbon moiety having 1 to 6 carbon atoms (e.g., hydroxyethyl,
hydroxypropyl, hydroxybutyl) or anionic substituents, such as carboxymethyl
groups are optional. These optional substituents are linked to the
polygalactomannan molecule by the reaction of the polygalactomannan molecule
with reagents such as (1) alkylene oxides (e.g., ethylene oxide, propylene oxide,
butylene oxide) to obtain hydroxyethyl groups, hydroxypropyl groups, or
hydroxybutyl groups, or with (2) chloromethyl acetic acid to obtain a
carboxymethyl group on the polygalactomannan. This reaction can take place
when the polygalactomannan is in the "split", "flour" or any other physical form.
The process for preparing derivatized polygalactomannan is well known in the
art.
In accordance with the present invention, surfactants are an important
ingredient in skin care formulations and can be used either alone of in
combination with other type of surfactants. The role of these surface active
agents is to reduce surface tension when dissolved in water or water solution, or
to reduce interfacial tension between two liquids, or between a liquid and a solid.
These characteristics are often used in providing in removal of undesirable
material from substrate such as skin or textile substrates. Examples of these
surfactants include anionic, nonionic, cationic, zwitterionic, amphoteric or
mixtures thereof type of surfactants. It is quite common to use mixtures of these
surfactants in skin care products. The surfactant can be insoluble (or soluble) in
the present invention and (when used) is present in the composition in the
amount of from 1.0 to 90 % by weight of the composition.
Anionic surfactants include alkyl and alkyl ether sulfates. Specific
examples of alkyl ether sulfates which can be used in the present invention are
sodium coconut alkyl trimethylene glycol ether sulfate; sodium tallow alkyl
trimethylene glycol ether sulfate; sodium tallow alkyl hexaoxyethylene sulfate;
sodium tallow alkyl diethylene glycol ether sulfate; and sodium tallow alkyl
sulfate. Other example of anionic surfactants are sulfonates, sulfosuccinates,
sacosinates, carboxylates, and isethionates.
Nonionic surfactants can be broadly defined as compounds containing a
hydrophobic moiety and a nonionic hydrophilic moiety. Examples of the
hydrophobic moiety can be alkyl, alkyl aromatic, dialkyl siloxane,
polyoxyalkylene, and fluoro-substituted alkyls. Examples of hydrophilic moieties
are polyoxyalkylenes, phosphine oxides, sulfoxides, amine oxides, and amides.
Other examples of nonionic surfactants include alkyl polysaccharides such as
alkyl polysaccharides.
Cationic surfactants useful in the compositions of the present invention
contain amino or quaternary ammonium hydrophilic moieties which are positively
charged when dissolved in an aqueous composition of the present invention.
Zwitterionic surfactants are exemplified by those which can be broadly
described as derivatives of aliphatic quaternary ammonium, phosphonium, and
sulfonium compounds, In which the aliphatic radicals can be straight or branched
chain, and wherein one of the aliphatic substituents contains from about 8 to
about 18 carbon atoms and one contains an anionic water-solubilizing group,
e.g., carboxy, sulfonate, sulfate, phosphate, or phosphonate.
Examples of amphoteric surfactants which can be used in the
compositions of the present invention are those which are broadly described as
derivatives of aliphatic secondary and. tertiary amines in which the aliphatic
radical can be straight or branched chain and wherein one of the aliphatic
substituents contains from about 8 to about 18 carbon atoms and one contains
an anionic water solubilizing group, e.g., carboxy, sulfonate, sulfate, phosphate,
or phosphonate.

In accordance with the invention, the silicone materials which can be used
are, in particular, polyorganosiloxanes that are insoluble in the composition and
can be in the form of polymers, oligomers, oils, waxes, resins, or gurns.
The organopolysiloxanes are defined in greater detail in Walter Noll's
"Chemistry and Technology of Silicones" (1968) Academic Press. They can be
volatile or non volatile.
If volatile, the silicones are more particularly chosen from those
having a boiling point of between 60" C. and 260° C., and even more particularly
from:
(i) cyclic silicones containing from 3 to 7 and preferably from 4 to 5
silicon
atoms. These are, for example, octamethylcyclotetrasiloxane sold in
particular under the name 'Volatile Silicone 7207" by Union Carbide or "Silbione
70045 V 2" by Rhone Poulenc, decamethyl cyclopentasiloxane sold under the
name" Volatile Silicone 7158" by Union Carbide, and "Silbione 70045 V 5" by
9
Rhone Poulenc, and mixtures thereof.
Mention may also be made of mixtures of cyclic silicones with
organosilicone compounds, such as the mixture of octamethylcyclotetrasiloxane
and tetratrimethylsilylpentaerythritol (50/50) and the mixture of
octamethylcyclotetrasiloxane and oxy I,P bis(2,2,2',2l
I3,3' hexatrimethylsilyloxy)
neopentane;
(ii) linear volatile silicones having 2 to 9 silicon atoms and having a
viscosity of less than or equal to 5x10-6 m2/s at 25° C. An example is
decamethyltetrasiloxane sold in particular under the name "SH 200" by Toray
Silicons company. Silicones belonging to this category are also described in the
article published in Cosmetics and Toiletries, Vol. 91, Jan. 76, pp. 27 32, Todd &
Byers "Volatile Silicone Fluids for Cosmetics".
Non volatile silicones, and more particularly polyarylsiloxanes,
polyalkylsiloxanes, polyalkylarylsiloxanes, silicone gums and resins,
polyorganosiloxanes modified with organofunctional groups, and mixtures
thereof, are preferably used.
In accordance with the invention, the silicone polymers and resins which
can be used are, in particular, polydiorganosiloxanes having high numberaverage
molecular weights of between 200,000 and 1,000,000, used alone or as
a mixture in a solvent. This solvent can be chosen from volatile silicones,
polydimethylsiloxane (PDMS) oils, polyphenylmethylsiloxane (PPMS) oils,
isoparaffins, polyisobutylenes, methylene chloride, pentane, dodecane and
tridecane, or mixtures thereof.
Examples of these silicone polymers and resins are as follows:

the invention are mixtures such as:
(a) mixtures formed from a polydimethylsiloxane hydroxylated at
the end of the chain (referred to as dimethiconol according to the
nomenclature in the CTFA dictionary) and from a cyclic
polydimethylsiloxane (referred to as cyciomethicone according to the
nomenclature in the CTFA dictionary), such as the product Q2 1401 sold
by the Dow Corning Company;
(b) mixtures formed from a polydimethylsiloxane gum with a cyclic
silicone, such as the product SF1214 Silicone Fluid from the company
General Electric Company; this product is .an SF 30 gum corresponding to
a dimethicone, having a number average molecular weight of 500,000,
dissolved in SF 1202 Silicone Fluid oil corresponding to
decamethylcyclopentasiloxane; and
(c) mixtures formed of two PDMSs of different viscosities, and

EXAMPLE 1
Body Wash - Sodium Luareth Sulfate/Cocamideamidopropyl betaine/Sodium Chloride
with N-Hance® 3215 and with AQU D3799 (Table 1 & 2)
This Example is to illustrate the invention and compare it with a prior art
commercial cationic polymer, N-Hance® 3215 product, that has a cationic DS of
about 0.2 and a weight average molecular weight (Mw) of 1,350,000 via size
exclusion chromatography. A cationic guar product of the present invention,
referred to as AQU D3799, has cationic DS of 0.63 and a weight average
Molecular weight of 1,120,000.
A stock solution of the body wash was made with a 10 % "hole" in it to
add salt thickener at a later stage has the following formulation:
35.31 g Deionized water
O.SOg Cationic guar N-Hance® 3215
43.64g Sodium Laureth Sulfate (SLES)
10.00g Cocamidopropyl betaine (CAPB)
OO.SOg DMDM Hydantoin
The N-Hance 3215 product was added to the water while mixing. Next, 5
% citric acid solution was added to N-Hance product and water mixture in order
to lower the pH to about 6.0. This mixture was mixed for an hour. The SLES
was added slowly to this mixture while mixing. The new mixture was continued
being mixed until the body wash mixture looked homogeneous. Next, the CAPB
was added while mixing. Again, the mixture was allowed to mix until
homogenous. Next, DMDM Hydantoin was added and mixed for about 10
minutes. The pH of the body wash was then adjusted to between 6 to 6.5 with
citric acid or sodium hydroxide solutions.
To 90.0 grams of this body wash, 25 % sodium chloride solution was
added to achieve desired salt concentration in the final body wash formulation.
For salt level above 2.5 % active, dry salt was added to the body wash. The
same procedure was followed for the polymer of this invention, AQU D3799.
The body wash viscosity was measured with Brookfield LVT viscometer.
Viscosity was measured at 25° C. Product stability was visually observed for
homogeneity, insoluble gels or phase separation. Body wash clarity was visually
rated as being "clear", "very slightly hazy," "slightly hazy", "moderately hazy", and
"very hazy", "considerable hazy", "sever hazy" and "opaque". This type of rating
is common in the Personal Care Industry for comparative expression of product
clarity study. Clarity also was measured at 600 nm using a Spectrophotometer,
Gary 5E UV-VIS-NIR, available from Varian Instruments, Inc., or equivalent. The
clarity measurements at 600 nm wavelength are reported as % T value in the
tables. The higher the number, the clearer is the solution.
In Tables 1 and 2, the two cationic guars were compared for their
compatibility in sodium laureth sulfate, cocamidopropyl betaine and sodium
chloride based body wash systems. Sodium chloride is a salt found in body wash
systems as a rheology modifier. With the N-Hance® 3215 product, a
commercially available cationic guar product, the body wash system was
unstable without the salt and with a very low salt level. In addition, as the salt
level was increased, the body wash system became unstable which was
reflected by poor clarity. Clarity was measured by measuring % T (transmittance
at 600 nm). At 3.0 % salts levels insoluble gels were observed. With the AQU
D3799 polymer of this invention, the body wash system was unstable in absence
of sodium chloride or at very low level of salt. However, it did not show instability
with increase in salt level as did the commercial N-Hance 3215 products.
A blind panel test was used to determine whether an individual can
aesthetically feel differences in body wash formulations prepared with the current
commercial N-Hance® 3215 product versus with the polymer of this invention,
AQU D3799. In the blind test a test member was asked to wash her hands first
with about 40°C plain water. Next, 2.0 ml of body wash was dispensed in the
palm of a test member's hands. The test member was asked to wash all sides of
both hands with the body wash for 30 seconds. Next, the panel members were
asked to wash their hands thoroughly with plain 40°C water for 30 seconds.
Hands were then pad dried with paper towels. During this cycle the test member
was asked to comment on lather properties, lather volume, ease of lather, ease
of rinsing and skin after feel. According to the test member, the body wash with
polymer of the invention gave very rich lather, was less slippery, and was more
conditioning as compared to the body wash formulated with the commercial NHance

In the ammonium laureth sulfate, cocamidopropyl betaine based body
wash, the product of this invention AQU D3799 mentioned previously showed
better product stability than the commercial product N-Hance® 3215 available
from Aqualon. See Tables 3 and 4.
A blind test was carried out to determine if a test subject could detect
differences in body wash formulations prepared with the current commercial NHance
® 3215 product versus with AQU D3799 of this invention. In the blind test
the test subject was asked first to wash her hands with about plain 40°C water.
Next, 2.00 ml of body wash was dispensed in the palm of the test subject's
hands and the test subject was asked to wash all sides of both hands with the
body wash for 30 seconds. Next, the test subject was asked to wash her hands
thoroughly under 40"C water for 30 seconds. The hands were then pad dried
with paper towel. During this cycle the test subject was asked to comment on
lather properties, lather volume, ease of lather, ease of rinsing and skin after
feel. According to the test subject body wash with polymer of the invention gave
better lather, richer lather, less slippery, good conditioning as compared to body
wash formulated with the commercial N-Hance® 3215 product.

invention ADPP6486 was compared In a body wash for their stability
performance to commercially available cationic guar polymer N-Hance 3215
product. The body wash based on the commercial polymer, N-Hance
3215product, had poor stability as compared to the polymer of this invention over
a broad range of salt concentration. The polymer of this invention showed a
significant improvement in clarity and compatibility with increase in ammonium
chloride salt. With the commercial product, the level of clarity using the product
of the invention was unable to be achieved.

Body Wash - Sodium Laureth Sulfate/Cocamidopropvl betaine/Sodlum Chloride
with N-Hance® 3215 and with ADPP 6486 (Table 10)
Stock body wash solution was made with 10 % "hole" in it to add salt
thickener at later stage as follows:
35.31 g Deionized water
0.50g N-Hance® 3215
43.64g Sodium Laureth Sulfate (SLES)
10.00g Cocamidopropyl betaine (CAPB)
OO.SOg DMDM Hydantoin
To deionized water, N-Hance® commercial 3215 product was added
while mixing. Next, 5 % citric acid solution was added to lower pH to about 6.0
and mixed for an hour or until polymer dissolved. Next, SLES was added slowly
while mixing and allowed to mix until homogeneous. Next, CAPB was added
while mixing. Again, the mixture was allowed to mix until homogenous. Next,
DMDM Hydantoin was added and mixed for about 10 minutes. The pH was
adjusted with citric acid or sodium hydroxide solution to between 9 to 9.6.
To 90.0 grams of this body wash solution, 10.0 grams of 25 % sodium
chloride solution was added to achieve the desired salt concentration in final
body wash formulation. Additional salt was added as dry salt when necessary to
achieve desired salt concentration
The body wash viscosity was measured with Brookfield® LVT viscometer.
Product stability was visually observed for homogeneity, insoluble gels or phase
separation. Body wash clarity was visually rated as being clear, very slightly
hazy slightly hazy, moderate hazy, hazy, very hazy, considerable hazy, sever
hazy, and opaque. This type of rating is common in the Personal Care Industry
for comparative studies. The clarity was also measured at 600 nm using a
Spectrophotometer, Gary 5E UV-VIS-NIR, available from Varian Instruments,
Inc., or equivalent The clarity measurements at 600 nm wavelength are
reported as %T value. The higher the number, the clearer is the solution.
Addition of salt such as sodium chloride improved the clarity and stability
of the body wash containing the guar product of this invention (i.e., ADPP 64-
86). This was not the case with commercially available N-Hance 3215 product.
In fact, the body wash became unstable with the addition of salt.

Preparation of Body Wash with N-Hance® 3215 and with ADPP6486. lot#
X33360-89-2 (Table 11)
N-Hance® 3215 and ADPP6486 polymers were added to water while
mixing. Next pH was lowered to about 6 with citric acid solution. Mixing was
continued until polymer dissolved. Next, ammonium lauryl sulfate, ammonium
laureth sulfate, cocamide MEA, Methyl Gluceth-20 and PEG-120 Methyl glucose
dioleate, DMDM Hydantoin were added in the order listed. Next body wash pH
was adjusted to about 6 with NaOH solution.
The addition of commercial N-Hance® 3215 increased viscosity of body
was significantly compared to the body wash made with the polymer of this
invention, ADPP6486. That is fora body wash formulation where conditioning
cationic guar is desired, commercial N-Hance® 3215 would be undesirable due
to significant increase in viscosity. A very high viscosity can make a difficult to
dispense the product. In fact, polymer of this invention had no significant effect
on the body wash viscosity when compared to body wash without the polymer of
invention. The additions of polymer of this invention improve foam stability of the
body wash over the body wash without any conditioning polymer. The lather
drainage time for body wash without the polymer of this invention was 31
seconds (30, 33 and 30 seconds) as compared to 42 seconds (48, 41,45 30 and
44 seconds) with polymer of this invention. A longer the lather drainage time, the
better is the lather stability.

Lather Drainage Test:
Objective of this is to measure the lather drainage time of a diluted body
wash solution. Long drainage times indicate a rich, dense lather with good
stability. The test was used to determine the influence polymers of this invention
may have on lather quality.
Equipment:
Waring® Blender Model #7012 or 34BL97 or equivalent.
Funnel, preferably plastic; 6" diameter, 7/8" ID neck, 5 %" high, with a
horizontal wire 2" from the top.
U.S.A. Standard Testing Sieve NO.20 or Tyler® Equivalent 20 mesh or
850 micrometer or 0.0331 inch sieve. Preferably over 7 inch in diameter
but smaller size could also be used

Procedure:
For each test formulation, 1000g of a diluted body wash solution was
prepared as shown below.
Body wash 066.13g
Deionized Water 933.87g
Total 1000.00g •
1. For each lather test measurement 200 grams of above diluted solution
was weighed and placed in a 25°C water-bath for 2 hours. Total of three jars
each with 200grams of solutions were prepared per body wash formulation
2. Next, the lather drainage time for each solution was measured using
the procedure described below.
a. Poured 200g of solution into a clean, dry Waring blender glass
vessel.
b. Whipped at the highest speed for exactly 1 minute while covered.
c. Foam generated in the jar was immediately poured into a clean,
dry funnel standing on a 20 mesh screen over a beaker.
d. Foam from the blender was poured for exactly 15 seconds. The
goal is to get as much foam as possible into the funnel without overflowing. After
15 seconds stopped pouring foam however, the stopwatch was kept running.
e. The total time needed for the foam to drain including the 15
seconds for pour time was recorded once the wire was no longer covered by
foam or liquid.
EXAMPLE 8
Preparation of Body Wash with N-Hance® 3215 and with ADPP6486. (Table 12)

After shower Skin Conditioning liquid (Table 16)
In container 1, hydroxyethyl cellulose was added to water and the pH was
adjusted to about 8.5. The mixture was stirred for 30 minutes or until the mixture
became a clear solution. Next, conditioning cationic polymer AQU D3799 and
AQU D3939 were added and mixed for an additional 30 minutes. This mixture
was heated to 65°C until the mixture became homogenous. Next, cetyl alcohol
was added and mixed until mixture became homogeneous and then it was
cooled to 50°C while mixing. Potassium chloride was next added. Isopropyl
myristate was then added and mixed until the mixture became homogeneous.
The pH was then adjusted to between 5.25 and .5.5. Afterwards, preservative
was added and cooled to room temperature while mixing.
To determine a conditioning properties of a polymer, hairs are often
treated with a conditioning agent dissolved or suspended in water and then hairs
combed to measure force required to comb hair. A lower the combing force
better the conditioning properties. Some time hair treated with fully formulated
product containing conditioning agent are also used by both product
manufacturers and the formulators. A lower the combing force, better the
conditioning properties of a polymer. The following conditioning formula without
the polymer required high stress to comb wet hair, about 4500gf-mm/g of hair
compared to only about 600 to 900gf-mm/g of hair for the formulation with
polymer of this invention. Similar trend was also observed for the dry hair. The
fallowing conditioning Tormuia witnout the polymer required high stress to comb
dry hair, about 325gf-mm/g of hair compared to only about 140gf-mm/g of hair
for the formulation with polymer of this invention. This is a strong indication that
polymer provides excellent conditioning. A commercial polymer GPX 247
provided combing energy for wet hair about 1390 gf-mm/g and for dry hair about
260gf-mm/g of hair
