Description

[0001] COSMETIC SUNSCREEN COMPOSITION AND USE OF THE COSMETIC SUNSCREEN COMPOSITION FIELD OF THE INVENTION

[0002] The present invention is directed to a cosmetic sunscreen composition comprising (a) at least one fatty compound, (b) Copernicia cerifera (carnauba) wax, (c) at least one filler, (d) at least one surfactant and (e) an UV filter system. The present invention is also related to a process of manufacturing the cosmetic sunscreen composition and its use.

[0003] BACKGROUND OF THE INVENTION

[0004] The photoprotection of keratinous materials, including both skin and hair, is considered of great importance in order to protect from sun-damage, sunburn, photoaging, as well as to decrease the chances of skin cancer development caused by exposure to ultraviolet (“UV”) radiation. There are typically two types of UVA / UVB sunscreen compositions used to accomplish photoprotection, namely, inorganic UV filters and organic UV filters.

[0005] Consumers are concerned with the negative effects of the sun exposition, particularly the hazardous effects of exposure to ultraviolet (“UV”) light. Prolonged exposure to sunlight causes damage, such as sunburn, to the skin. When skin is exposed to UV light having a wavelength of from about 290 nm to about 400 nm, longterm damage can lead to serious conditions, such as skin cancer. UV light also contributes to aging by causing free radicals to form in the skin. Free radicals include, for example, singlet oxygen, hydroxyl radical, the superoxide anion, nitric oxide and hydrogen radicals. Free radicals attack DNA, membrane lipids and proteins, generating carbon radicals. These in turn react with oxygen to produce a peroxyl radical that can attack adjacent fatty acids to generate new carbon radicals. This cascade leads to a chain reaction producing lipid peroxidation products. Damage to the cell membrane results in loss of cell permeability, increased intercellular ionic concentration, and decreased ability to excrete or detoxify waste products. The end result is a loss of skin elasticity and the appearance of wrinkles. This process is commonly referred to as photo-aging.

[0006] In this sense, in a skin care regimen, consumers apply cosmetic sunscreen compositions to protect the skin and the perception of the product on the skin is very important.

[0007] Consumers are increasingly looking for fluid / light cosmetic sunscreen textures that fit into their photoprotection routing while protect the skin with high degree of UV protection (UVA / UVB).

[0008] The degree of UV protection of a cosmetic sunscreen composition is directly related to the amount and type of UV filters contained therein. The higher the amount of UV filters, the greater the degree of UV protection (UVA / UVB).

[0009] Particularly, sunscreen compositions must provide good protection against the sun, a measure of which is the Sun Protection Factor (SPF) value, yet have satisfactory sensory perception, not greasy feel upon application.

[0010] For said reasons, there is a need to develop new fluid / light cosmetic sunscreen compositions having the properties: having high stability, comprising green ingredients, having good sensory properties, having good absorption and spreadability and delivering high SPF.

[0011] The inventors of the present invention have overcome the drawbacks of the state of the art and surprisingly achieved a fluid / light cosmetic sunscreen composition comprising the properties mentioned above, with high SPF, good sensorial attributes, easy spreadability, light film, green ingredients and stability comprising: (a) at least one fatty compound, (b) Copernicia cerifera (carnauba) wax, (c) at least one filler, (d) at least one surfactant and (e) an UV filter system.

[0012] SUMMARY OF THE INVENTION

[0013] The present invention is directed to a cosmetic sunscreen composition comprising (a) at least one fatty compound, (b) Copernicia cerifera (carnauba) wax, (c) at least one filler, (d) at least one surfactant and (e) an UV filter system. The present invention is also related to the use of the cosmetic sunscreen composition to be used as sunscreen daily product.

[0045] SILICA AEROGEL (SILICA SILYLATE)

[0046] The “silica aerogel” according to the present invention is a porous material obtained by replacing (by drying) the liquid component of a silica gel with air. Silica aerogels are generally synthesized via a sol-gel process in a liquid medium and then dried, usually by extraction with a supercritical fluid, such as, but not limited to, supercritical carbon dioxide (CO2). This type of drying makes it possible to avoid shrinkage of the pores and of the material. The sol-gel process and the various drying processes are described in detail in Brinker, C.J., and Scherer, G.W., Sol-Gel Science: New York: Academic Press, 1990. The silica aerogel particles used in the present invention have a specific surface area per unit of mass (SM) ranging from about 500 to about 1500 m2 / g, or alternatively from about 600 to about 1200 m2 / g, or alternatively from about 600 to about 800 m2 / g, and a size expressed as the mean volume diameter (D[0.5]), ranging from about 1 to about 30 pm, or alternatively from about 5 to about 25 pm, or alternatively from about 5 to about 20 pm, or alternatively from about 5 to about 15 pm. The specific surface area per unit of mass may be determined via the BET (Brunauer- Emmett-Teller) nitrogen absorption method described in the Journal of the American Chemical Society, vol. 60, page 309, February 1938, corresponding to the international standard ISO 5794 / 1 . The BET specific surface area corresponds to the total specific surface area of the particles under consideration.

[0047] The size of the silica aerogel particles may be measured by static light scattering using a commercial granulometer such as the MasterSizer 2000 machine from Malvern. The data are processed on the basis of the Mie scattering theory. This theory, which is exact for isotropic particles, makes it possible to determine, in the case of non-spherical particles, an "effective" particle diameter. This theory is especially described in the publication by Van de Hulst, H.C., "Light Scattering by Small Particles," Chapters 9 and 10, Wiley, New York, 1957.

[0048] The silica aerogel particles used in the present invention may advantageously have a tamped (or tapped) density ranging from about 0.04 g / cm3to about 0.10 g / cm3’ or alternatively from about 0.05 g / cm3to about 0.08 g / cm3. In the context of the present invention, this density, known as the tamped density, may be assessed according to the following protocol: 40 g of powder are poured into a measuring cylinder; the measuring cylinder is then placed on a Stav 2003 machine from Stampf Volumeter; the measuring cylinder is then subjected to a series of 2500 packing motions (this operation is repeated until the difference in volume between two consecutive tests is less than 2%); the final volume Vf of packed powder is then measured directly on the measuring cylinder. The tamped density is determined by the ratio m / Vf, in this instance 40 / Vf (Vf being expressed in cm3and m in g).

[0049] According to one embodiment, the silica aerogel particles used in the present invention have a specific surface area per unit of volume Sv ranging from about 5 to about 60 m2 / cm3, or alternatively from about 10 to about 50 m2 / cm3, or alternatively from about 15 to about 40 m2 / cm3. The specific surface area per unit of volume is given by the relationship: Sv = SM. r where r is the tamped density expressed in g / cm3and SM is the specific surface area per unit of mass expressed in m2 / g, as defined above.

[0050] In some embodiments, the silica aerogel particles, according to the invention, have an oil-absorbing capacity, measured at the wet point, ranging from about 5 to about 18 ml / g, or alternatively from about 6 to about 15 ml / g, or alternatively from about 8 to about 12 ml / g. The oil-absorbing capacity measured at the wet point, noted Wp, corresponds to the amount of water that needs to be added to 100 g of particle in order to obtain a homogeneous paste. Wp is measured according to the wet point method or the method for determining the oil uptake of a powder described in standard NF T 30-022. Wp corresponds to the amount of oil adsorbed onto the available surface of the powder and / or absorbed by the powder by measuring the wet point, described below: An amount = 2 g of powder is placed on a glass plate, and the oil (isononyl isononanoate) is then added dropwise. After addition of 4 to 5 drops of oil to the powder, mixing is performed using a spatula, and addition of oil is continued until a conglomerate of oil and powder has formed. At this point, the oil is added one drop at a time and the mixture is then triturated with the spatula. The addition of oil is stopped when a firm, smooth paste is obtained. This paste must be able to be spread on the glass plate without cracking or forming lumps. The volume Vs (expressed in ml) of oil used is then noted. The oil uptake corresponds to the ratio Vs / m.

[0051] The aerogels used, according to the present invention, are hydrophobic silica aerogels, preferably of silylated silica (INCI name: silica silylate). The term "hydrophobic silica" means any silica whose surface is treated with silylating agents, for example, halogenated silanes, such as alkylchlorosilanes, siloxanes, in particular dimethylsiloxanes, such as hexamethyldisiloxane, or silazanes, so as to functionalize the OH groups with silyl groups Si-Rn, for example, trimethylsilyl groups. Preparation of hydrophobic silica aerogel particles that have been surface-modified by silylation, is found in U.S. Patent No. 7,470,725, incorporated herein by reference. In one embodiment, hydrophobic silica aerogel particles surface-modified with trimethylsilyl groups are desirable.

[0052] Suitable examples of hydrophobic silica aerogels may include, but are not limited to, the aerogels sold under the tradenames of VM-2260 (INCI name: Silica silylate) and VM-2270 (INCI name: Silica silylate), both available from Dow Corning Corporation (Midland, Michigan). The particles of VM-2260 have a mean size of about 1000 microns and a specific surface area per unit of mass ranging from 600 to 800 m2 / g. The particles of VM-2270 have a mean size ranging from 5 to 15 microns and a specific surface area per unit of mass ranging from 600 to 800 m2 / g. Another suitable example of a hydrophobic silica aerogel may include, but is not limited to, the aerogels commercially available from Cabot Corporation (Billerica, Massachusetts) under the tradename of Aerogel TLD 201 , Aerogel OGD 201 and Aerogel TLD 203, Enova Aerogel MT 1 100 and Enova Aerogel MT 1200.

[0053] The silica aerogel is preferably hydrophobic silica aerogel, more preferably silica silylate.

[0054] PERLITE PARTICLES

[0055] Perlite is a natural glass of volcanic origin, of glossy black or light grey colour, resulting from the rapid cooling of lava, and which is in the form of small particles resembling pearls.

[0056] The perlites which can be used according to the invention are generally aluminosilicates of volcanic origin and have the composition:

[0057] 70.0-75.0% by weight of silica SIO2

[0058] 12.0-15.0% by weight of aluminum oxide AI2O3

[0059] 3.0-5.0% of sodium oxide Na20

[0060] 3.0-5.0% of potassium oxide K2O

[0063] 0.5-1 .5% of calcium oxide CaO

[0064] 0.05-0.15% of titanium dioxide TIO2.

[0065] Preferentially, the perlite particles used according to the invention will be in porous expanded form.

[0066] The perlite is ground, dried and then calibrated in a first stage. The product obtained, known as perlite ore, is grey-coloured and has a size of the order of 100 pm. The perlite ore is subsequently expanded (1000sC / 2 seconds) to give more or less white particles. When the temperature reaches 850-900sC, the water trapped in the structure of the material evaporates and brings about the expansion of the material, with respect to its original volume. The expanded perlite particles in accordance with the invention may be obtained via the expansion process described in patent US 5 002 698.

[0067] Preferably, the perlite particles used will be ground; in this case, they are known as Expanded Milled Perlite (EMP).4

[0068] They preferably have a particle size defined by a median diameter D50 ranging from 0.5 to 50 gm and preferably from 0.5 to 40 pm.

[0069] Preferably, the perlite particles according to the invention have a particle size distribution such that at least 50% of the particles are less than 20 pm in size. In addition, they preferentially have a particle size distribution such that 90% by weight of the particles are less than 55 pm in size and preferably less than 40 pm in size. It is moreover preferred for 90% by weight of the particles to be greater than 5 pm in size.

[0070] Preferably, the perlite particles used have an apparent density at 25SC ranging from 10 to 400 kg / m3(standard DIN 53468) and preferably from 10 to 300 kg / m3.

[0094] The silicones used for the coating(s) can be and in some embodiments are selected from the group consisting of alkylsilanes, polydialkylsiloxanes, and polyalkylhydrosiloxanes. And in some embodiments still, the silicones are selected from the group consisting of octyltrimethylsilane, polydimethylsiloxanes, and polymethylhydrosiloxanes.

[0095] Of course, the inorganic UV filters made of metal oxides may, before their treatment with silicones, have been treated with other surfacing agents, in particular with cerium oxide, alumina, silica, aluminum compounds, silicon compounds, or their mixtures. The coated inorganic UV filter may have been prepared by subjecting the inorganic UV filter to one or more surface treatments of a chemical, electronic, mechano-chemical, and / or mechanical nature with any of the compounds as described above, as well as polyethylenes, metal alkoxides (titanium or aluminum alkoxides), metal oxides, sodium hexametaphosphate, and those shown, for example, in Cosmetics & Toiletries, February 1990, Vol. 105, pp. 53-64.

[0096] The coated inorganic UV filters may be titanium oxides coated: with silica, such as the product "Sun veil" from Ikeda, and "Sunsil TIN 50" from Sunjin Chemical; with silica and with iron oxide, such as the product "Sunveil F" from Ikeda; with silica and with alumina, such as the products "Microtitanium Dioxide MT 500 SA" from Tayca, "Tioveil" from Tioxide, and "Mirasun TiW 60" from Rhodia; with alumina, such as the products "Tipaque TTO-55 (B)" and "Tipaque TTO-55 (A)" from Ishihara, and "UVT 14 / 4" from Kemira; with alumina and with aluminum stearate, such as the product "Microtitanium Dioxide MT 100 T, MT 100 TX, MT 100 Z or MT-01" from Tayca, the products "Solaveil CT-10 W" and "Solaveil CT 100" from Uniqema, and the product "Eusolex T-AVO" from Merck; with alumina and with aluminum laurate, such as the product "Microtitanium Dioxide MT 100 S" from Tayca; with iron oxide and with iron stearate, such as the product "Microtitanium Dioxide MT 100 F" from Tayca; with zinc oxide and with zinc stearate, such as the product "BR351" from Tayca; with silica and with alumina and treated with a silicone, such as the products "Microtitanium Dioxide MT 600 SAS", "Microtitanium Dioxide MT 500 SAS", and "Microtitanium Dioxide MT 100 SAS" from Tayca; with silica, with alumina and with aluminum stearate and treated with a silicone, such as the product "STT-30-DS" from Titan Kogyo; with silica and treated with a silicone, such as the product "UV- Titan X 195" from Kemira; with alumina and treated with a silicone, such as the products "Tipaque TTO-55 (S)" from Ishihara or "UV Titan M 262" from Kemira; with triethanolamine, such as the product "STT-65-S" from Titan Kogyo; with stearic acid, such as the product "Tipaque TTO-55 (C)" from Ishihara; or with sodium hexametaphosphate, such as the product "Microtitanium Dioxide MT 150 W" from Tayca. Other titanium oxide pigments treated with a silicone are, and in some embodiments Ti02 treated with octyltrimethylsilane and for which the mean size of the individual particles is from 25 and 40 nm, such as that marketed under the trademark "T 805" by Degussa Silices, Ti02 treated with a polydimethylsiloxane and for which the mean size of the individual particles is 21 nm, such as that marketed under the trademark "70250 Cardre UF TiO2Si3" by Cardre, and anatase / rutile TiO2 treated with a polydimethylhydrosiloxane and for which the mean size of the individual particles is 25 nm, such as that marketed under the trademark "Microtitanium Dioxide USP Grade Hydrophobic" by Color Techniques.

[0097] And in some embodiments, the following coated Ti02 can be used as the coated inorganic UV filter: Stearic acid (and) Aluminum Hydroxide (and) TiC , such as the product "MT-100 TV" from Tayca, with a mean primary particle diameter of 15 nm; Dimethicone (and) Stearic Acid (and) Aluminum Hydroxide (and) TiC , such as the product "S A-TTO-S4" from Miyoshi Kasei, with a mean primary particle diameter of 15 nm; Silica (and) TiC , such as the product "MT-100 WP" from Tayca, with a mean primary particle diameter of 15 nm; Dimethicone (and) Silica (and) Aluminum Hydroxide (and) TiC , such as the product "MT-Y02" and "MT-Y-110 M3S" from Tayca, with a mean primary particle diameter of 10 nm; Dimethicone (and) Aluminum Hydroxide (and) TiC , such as the product "SA-TTO-S3" from Miyoshi Kasei, with a mean primary particle diameter of 15 nm; Dimethicone (and) Alumina (and) TiC , such as the product "UV TITAN Ml 70" from Sachtleben, with a mean primary particle diameter of 15 nm;. and Silica (and) Aluminum Hydroxide (and) Alginic Acid (and) Ti O2, such as the product "MT- 100 AQ" from Tayca, with a mean primary particle diameter of 15 nm. In terms of UV filtering ability, TiC coated with at least one organic UV filter is more desirable. For example, Avobenzone (and) Stearic Acid (and) Aluminum Hydroxide (and) TiC , such as the product "HXMT-100ZA" from Tayca, with a mean primary particle diameter of 15 nm, can be used.

[0098] The uncoated titanium oxide pigments are, for example, marketed by Tayca under the trademarks "Microtitanium Dioxide MT500B" or "Microtitanium Dioxide MT600B", by Degussa under the trademark "P 25", by Wacker under the trademark "Oxyde de titane transparent PW", by Miyoshi Kasei under the trademark "UFTR", by Tomen under the trademark "ITS" and by Tioxide under the trademark "Tioveil AQ".
