FORM - 2 THE PATENTS ACT, 1970 (39 of 1970) & The Patents Rules, 2006 COMPLETE SPECIFICATION (See Section 10 and Rule 13) PIGMENTED COSMETIC COMPOSITION EXHIBITING RADIANCE WITH SOFT FOCUS HINDUSTAN LEVER LIMITED, a company incorporated under the Indian Companies Act, 1913 and having its registered office at Hindustan Lever House, 165/166, Backbay Reclamation, Mumbai -400 020, Maharashtra, India The following specification particularly describes the invention and the manner in which it is to be performed WO 2005/070382 l»CT/EI'2004/OII363 - 1 – - PIGMENTED COSMETIC COMPOSITION EXHIBITING RADIANCE WITH SOFT FOCUS The invention relates to compositions for improving the appearance of skin, particularly to provide good coverage over imperfections 5 such as pores and uneven skin tone, while retaining a natural skin, appearance. Background to the Invention A matte effect is desired for users of color cosmetics. The matte finish overcomes the shiny effect engendered by greasy skin, 10 particularly under hot and humid conditions. Absorbent fillers such as talc, silica, kaolin and other inorganic particulates have been used to achieve the effect by their optical properties. Imperfect skin can be hidden in two ways through manipulation off light transmission. In the first, components of the color cosmetic: 15 may simply reflect light back toward the source. An alternative approach is referred to as achieving a soft focus effect. Here the incoming light is distorted by scattering (lensing). Components of the color cosmetic in this mechanism operate as lenses to bend and twist light into a variety of directions. 20 While it is desirable to hide imperfect skin through a matte effect, there is also a desire to achieve a healthy skin radiance- A cosmetic covering that is too opaque hides the skin under a paint-like coating. Imperfections are hidden but there is no radiance -Where light transmission is insufficiently hindered, the opposite 25 occurs. Here the glow may be healthy but aesthetically displeasing skin topography and color may now be apparent. WO 2005/070382 PCT/EP2004/011363 - 2 - US Patent 5,997,890 (Sine et al.), US Patent 5,972,359 (Sine et al.), and US Patent 6,174,533 Bl (SaNogueira, Jr.) are all directed to topical compositions to provide good coverage of skin imperfections. The solution proposed by these documents is the use 5 of a metal oxide with a refractive index of at least about 2 and a neat primary particle size of from about 100 to about 300 nm. Preferred particulates are titanium dioxide, zirconium oxide and zinc oxide. Silicone gelling agents such as crosslinked organopolysiloxane 10 elastomers because of their excellent skinfeel properties have been found useful in make-up compositions. For instance, US Patent 5,266,321 (Shukuzaki et al.) discloses an oily make-up composition comprised of a silicone gel crosslinked elastomer, titanium dioxide, mica and iron oxides. Japanese patent application 61-194009 15 (Harashima) describes a make-up composition comprising a cured organopolysiloxane elastomer powder and pigments which may be selected from talc, titanium dioxide, zinc oxide and iron oxides. A challenge which has not been fully met by the known art is delivery of a composition with appropriate optics to achieve both 20 soft focus and radiance properties in a system that still provides excellent skinfeel. 1181811 J6881(C)PCT - 3 - Summary of the Invention A cosmetic composition is provided which includes: (i) a crosslinked silicone elastomer; . (ii) a zinc oxide of average particle size less than 300 nm; 5 (iii) a light reflecting inorganic material of platelet shaped particles having an average particle size of about 10,000 to about 30,000 nm; and (iv) a cosmetically acceptable carrier system. 10 Detailed Description of the Invention Now it has been observed that a soft focus effect with radiance can be obtained by a combination of fine particle sized zinc oxide or zirconium oxide suspended with a crosslinked silicone elastomer. The zinc or zirconium oxide must have an average 15 particle size less than 300 nm. Absent the elastomer or the zinc or zirconium oxide, there would be insufficient soft focus effect. The oxide alone is inefficient because of excessive loss of reflectance/radiance. Crosslinked Silicone Elastomer 20 A component of the present invention is a crosslinked silicone (organopolysiloxane) elastomer. No specific restriction exists as to the type of curable organopolysiloxane composition that can serve as starting material for the crosslinked silicone elastomer. Examples in this respect are addition reaction- 25 curing organopolysiloxane compositions which cure under platinum metal catalysis by the addition reaction between SiH-containing WO 2005/070382 PCT/EP2004/011363 - 4 - diorganopolysiloxane and organopolysiloxane having silicon-bonded vinyl groups; condensation-curing organopolysiloxane compositions which cure in the presence of an organotin compound by a dehydrogenation reaction between hydroxyl terminated 5 diorganopolysiloxane and SiH-containing ' diorganopolysiloxane; condensation-curing organopolysiloxane compositions which cure in the presence of an organotin compound or a titanate ester, by a condensation reaction between an hydroxyl terminated diorganopolysiloxane and a hydrolyzable organosilane (this 10 condensation reaction is exemplified by dehydration, alcohol-liberating, oxime-liberating, amine-liberating, amide-liberating, carboxyl-liberating, and ketone-liberating reactions); peroxide-curing organopolysiloxane compositions which thermally cure in the presence of an organoperoxide 15 catalyst; and organopolysiloxane compositions which are cured by high-energy radiation, such as by gamma-rays, ultraviolet radiation, or electron beams. Addition reaction-curing organopolysiloxane compositions are preferred for their rapid curing rates and excellent uniformity 20 of curing. A particularly preferred addition reaction-curing organopolysiloxane composition is prepared from: (A) an organopolysiloxane having at least 2 lower alkenyl groups in each molecule; (B) an organopolysiloxane having at least 2 silicon-bonded (C) 25 hydrogen atoms in each molecule; and (D) a platinum-type catalyst. The crosslinked siloxane elastomer of the present invention may either be an emulsifying or non-emulsifying crosslinked WO 2005/070382 PCT/EP2004/011363 - 5 - organopolysiloxane elastomer or combinations thereof. The term "non-emulsifying," as used herein, defines crosslinked organopolysiloxane elastomer from which polyoxyalkylene units are absent. The term "emulsifying," as used herein, means 5 crosslinked organopolysiloxane elastomer having at least one polyoxyalkylene (e.g., polyoxyethylene or polyoxypropylene) unit. Particularly useful emulsifying elastomers are polyoxyalkylene-modified elastomers formed from divinyl compounds, particularly 10 siloxane polymers with at least two free vinyl groups, reacting with Si-H linkages on a polysiloxane backbone. Preferably, the elastomers are dimethyl polysiloxanes crosslinked by Si-H sites on a molecularly spherical MQ resin. Preferred silicone elastomers are organopolysiloxane 15 compositions available under the INCI names of dimethicone/vinyl dimethicone crosspolymer, dimethicone crosspolymer and Polysilicone-ll. Ordinarily these materials are provided as a 1-30% crosslinked silicone elastomer dissolved or suspended in a dimethicone fluid (usually cyclomethicone) . For purposes of 20 definition "crosslinked silicone elastomer" refers to the elastomer alone rather than the total commercial compositions which also include a solvent (e.g. dimethicone) carrier. Dimethicone/vinyl dimethicone crosspolymers and dimethicone crosspolymers are available from a variety of suppliers 25 including Dow Corning (9040, 9041, 9045, 9506 and 9509), General Electric (SFE 839), Shin Etsu (KSG-15, 16, 18 [dimethicone/phenyl vinyl dimethicone crosspolymer] ), and Grant WO 2005/070382 PCT/EP2004/011363 - 6 - Industries (Gransil™ line of materials) , and lauryl dimethicone/vinyl dimethicone crosspolymers supplied by Shin Etsu (e.g., KSG-31, KSG-32, KSG-41, KSG-42, KSG-43, and KSG-44). Other suitable commercially available silicone elastomer powders 5 include vinyl dimethicone/methicone silesquioxane crosspolymers from Shin-Etsu sold as KSP-100, KSP-101, KSP-102, KSP-103, KSP-104, KSP-105, and hybrid silicone powders that contain a fluoroalkyl group or a phenyl group sold by Shin-Etsu as respectively KSP-200 and KSP-300. 10 The crosslinked silicone elastomers of the present invention may range in concentration from about 0.01 to about 30%, preferably from about 0.1 to about 10%, optimally from about 0.5 to about 2% by weight of the cosmetic composition. These weight values exclude any solvent such as cyclomethicone found in commercial 15 "elastomer" silicones such as the Dow Corning products 9040 and 9045. For instance, the amount of crosslinked silicone elastomer in 9040 and 9045 is between 12 and 13% by weight. Most preferred as the silicone elastomer is 9045 which has a D5 cyclomethicone swelled elastomer particle size (based on volume 20 and calculated as spherical particles) which averages about 38 micron, and may range from about 25 to about 55 micron. Micronized Zinc or Zirconium Oxide A second important component of the present invention is that of a micronized zinc oxide or zirconium oxide having average 25 (number) particle sizes less than 300 nm, preferably less than 200 nm, more preferably less than 100 nm and optimally less than WO 2005/070382 PCT/EP2004/011363 - 7 - 85 nm. Generally the particle sizes can range from about 0.01 to about 280 nm, more preferably from about 1 to about 200 nm, even more preferably from 10 to 95 nm, and optimally from 25 to 75 nm. 5 Average particle size of the oxide assumes a spherical shape and is defined as the diameter of the particle averaged over many particles. The average value is a number average. For spherical particles such as the zinc oxide, laser light scattering is utilized to determine the individual sizes of the 10 particles and generate a particle size distribution plot. Based upon the distribution plot, the average particle size can be determined. In more mathematical terms, the average particle size is a diameter converted from the meso-pore specific surface area determined by the t-plot method (particle size converted 15 excluding the specific surface area of micro pores of less than 20 Angstrom). In detail, the average particle size D, assuming the particle as spherical form, can be obtained by the following equation.- D=6/pS, where S (m2/g) represents a meso-pore specific surface area and p(g/cm3) is the density. 20 The amount of zinc oxide or zirconium oxide may range from about 0.1 to about 20%, preferably from about 0.5 to about 10%, optimally from about 1 to about 5% by weight of the cosmetic composition. Since zinc or zirconium oxide particles are applied to skin, it 25 is desirable that they be free of toxic trace metal contaminants. A particularly preferred zinc oxide has trace concentrations of lead (less than 20 ppm) , arsenic (less than 3 WO 2005/070382 PCT/EP2004/011363 - 8 - ppm), cadmium (less than 15 ppm) and mercury (less than 1 ppm). This material is commercially available from BASF Corporation under the trademark of Z-Cote HP1. These particles are best delivered to the formula as a pre-mix of 5-80% weight by weight 5 suspended in an organic ester base. Zinc oxide or zirconium oxide particles of the present invention advantageously but not necessarily are substantially spherical in shape. The refractive index of these particles may preferably range from about 1.8 to about 2.3. Measurement of 10 refractive index can be performed according to a method described in J.A. Dean, Ed., Lange's Handbook of Chemistry, 14th Ed., McGraw Hill, New York 1992, Section 9, Refractometry, incorporated herein by reference. Light Reflecting Platelet Particles 15 A third important component of compositions according to the present invention is that of light reflecting platelet shaped particles. These particles will have an average particle size D5o ranging from about 10,000 to about 30,000 nm. For platelike materials the average particle size is a number average 20 value. The platelets are assumed to have a circular shape with the diameter of the circular surface averaged over many particles. The thickness of the plate-like particles is considered to be a separate parameter. For instance, the platelets can have an average particle size of 35,000 nm and an 25 average thickness of 400 nm. For purposes herein, thickness is considered to range from about 100 to about 600 nm. Laser light scattering can be utilized for measurement except that light WO 2005/070382 PCT7EP2004/011363 - 9 - scattered data has to be mathematically corrected from the spherical to the non-spherical shape. Optical and electron microscopy may be used to determine average particle size. Thickness is normally only determined via optical or electron 5 microscopy. The refractive index of these particles is preferred to be at least about 1.8, generally from about 1.9 to about 4, more preferably from about 2 to about 3, optimally between about 2.5 and 2.8. 10 Illustrative but not limiting examples of light reflecting particles are bismuth oxychloride (single crystal platelets) and titanium dioxide coated mica.

A crystalline structurant advantageously may be present in 10 compositions according to the present invention. The structurant may include both a surfactant and a co-surfactant. The nature of the surfactant and co-surfactant will depend upon whether the crystalline structurant is anionic or nonionic. For structurants that are anionic, the preferred surfactants are C10 15 C22 fatty acids and salts (i.e. soap) thereof and particularly combinations of these materials.

Nonionic type crystalline structurant will have a surfactant and a 20 co-surfactant different than that for the anionic systems. Preferred nonionic structurant surfactants are C1-C200 esters of C10-C22 fatty acid. Esters of the fatty acid preferably are polyol esters such as C2-C3 alkoxylated alcohol or sorbitol esters. Among these are the polyethoxy, polypropoxy and block 25 polyethoxy /polypropoxy alcohol esters. Particularly preferred are such esters as Polysorbate 40, Polysorbate 60, PEG-100 stearate, PEG-20 stearate, PEG-80 laurate, PEG-20 laurate, PEG-100 palmitate, PEG-20 palmitate and combinations thereof. WO 2005/0703X2 1>2004/0U.M»3 - 18 - The co-surfactant of a nonionic structurant typically may be a combination of a C10-C22 fatty alcohol, glyceryl esters of a C10-C22 fatty acid, and a Ci0-C22 unesterified fatty acid. Relative amounts of the ester to the alcohol may range from about 100:1 to about 5 1:100, preferably from about 50:1 to about 1:50, and optimally from about 3:1 to about 1:3 by weight. Relative amounts of the combination of glyceryl ester and fatty alcohol to unesterified fatty acid may range from about 100:1 to about 1:100, preferably from about 50:1 to about 1:50, and optimally from about 3:1 to about 10 1:3 by weight. Typical fatty alcohols include behenyl alcohol, stearyl alcohol, cetyl alcohol, myristyl alcohol, lauryl alcohol, oleyl alcohol and combinations thereof. The relative amount of surfactant and co-surfactant in a nonionic structurant may range from about 50:1 co about 1:50, preferably from 15 about 10:1 to about 1:10, and optimally from about 3:1 to about 1:3 by weight. A crystalline structurant is formed by the surfactant and co-surfactant. Indeed, the surfactant and co-surfactant combination in their relative ratio and type of material is defined by an enthalpy 20 which may range from about 2 to about 15, preferably from about 2.5 to about 12, and optimally from about 3.5 to about 8 Joules per gram, as measured by Differential Scanning Calorimetry. Furthermore, the crystalline structurant system advantageously may have a melting point ranging from about 30 to about 70°C, preferably 25 from about 45 to about 65°C, and optimally from about 50 to about 60°C. Normal forces which are positive numbers reflect a silky smooth skin feel of the formulation. Negative values have been identified with WO 2005/070382 PCT/EP2004/011363 - 19 - a draggy feel which many consumers dislike. Normal force is measured in the following manner. A rheometer that has a shear rate mode capability and a normal force transducer is utilized to measure the high shear normal force. These devices are available from 5 Rheometric Scientific ARES, TA Instruments AR2000, and Paar Physica MCR. Samples are compressed between concentric parallel plates of diameter 25 mm and gap (vertical distance between the two plates) of 100 microns. The measurements are made in a continuous logarithmic shear sweep mode with a shear rate range of 1 to 10,000 s"1. Each 10 sweep takes 5 minutes and is conducted at ambient condition (20-25°C). The normal force is calculated by subtracting the baseline (defined as the normal force value at or near 100 s"1) from the highest normal force value measured between 1000 and 10,000 s'1. A positive normal force of 5 grams and especially 10 grams or greater 15 is correlated to products/materials with silky sensations during rubbing in application.

The higher the direct beam attenuation, the greater will be the opacity. 5 The source of the light beam attenuation is two fold: A) Some of the original light is reflected back from the film/medium. This gives the film/medium a true white/opaque appearance with great hiding power. Using pigment-grade Ti02 in a formulation will give the effect. B) Some of the light is deflected from the 10 straight beam path but still transmitted through the film/medium. In effect, the film/medium goes from being transparent to translucent, creating a "blurred" image. Another term for this is soft focus. Procedure: Apply (or draw down) a 3 mil (76.2 um) film of a 15 formulation using a draw down bar on to a plastic overhead transparency sheet. Let the film dry for 2 hours at room temperature. Take the coated overhead transparency and place it in an Instrument Systems goniospectrophotometer. Set the light source and detector arrayed in a straight line perpendicular to 20 the coated transparency. The light source (set at 209 million Watt-nm/cm2, which serves as a reference for all Transmission Intensity values reported herein) is turned on and the measurement of the transmitted light intensity is made. Further measurements are made by moving the detector 10, 30, 40, 50 25 degrees away from the direct transmission normal. These values indicate the extent of soft focus light scattering. The Reflectance or "radiance" of a product is determined in the same way as opacity/soft focus light scattering, except for the WO 2005/070382 PCT/EP2004/011363 - 29 - positions of the light source and detector. The detector is 30 degrees on one side of the normal/perpendicular, while the light source is 20 degrees on the other side. To determine the extent of the intensity attenuation, compare the intensity value to 5 that of an uncoated overhead transparency. The difference between these two values is the extent of the attenuation or opacity. Results: The effect of certain components on the optical properties of the compositions was evaluated by testing 10 formulations with those components removed. Results are reported in Table II.

WO 2005/070382 PCT/EP2004/0U363 - 31 - Sample 1 is a preferred embodiment of the present invention. Transmission Intensity (Opacity) at all angles and Reflection Intensity for this formula fell within the parameters necessary to achieve both soft focus and radiance. Replacement of the 5 silicone elastomer (Dow Corning 9045) with cyclopentasiloxane (Dow Coming 245) in Sample 2 resulted in a Transmission Intensity at four angles outside the acceptability ranges. In Sample 3 the zinc oxide was omitted. Here the Transmission Intensity was also outside four of the acceptable ranges 10 indicating the necessity of zinc oxide to achieve soft focus. Removal of Ganzpearl® GMP-0820, which consists of polymethylmethacrylate beads, in Sample 4 had only a small affect on the opacity. Sample 5 wherein Satin Mica was removed as expected demonstrated greater light transmission, but the 15 Reflection Intensity and the 0° angle Transmission Intensity were outside the acceptable range. Removal of Timiron® MP 111 (titanium dioxide coated mica) in Sample 6 demonstrated that this component was a very significant contributor to the soft focus/radiance effect. In Samples 7 and 8 the amount of 20 Aristoflex AVC® (taurate copolymer) was reduced. The 0° angle and 30° angle Transmission Intensity values were the only ones outside the acceptable range indicating that this copolymer had an influence and contributed to the soft focus effect. Example 2 25 In this Example we investigated the effect of zinc oxide in contrast to titanium dioxide of essentially similar average particle sizes. The Formulas investigated are given in Table III .
