INCREASING THE SUN PROTECTION FACTOR

The present invention relates to a fluid composition intended for protecting the skin and/or hair against ultraviolet radiation, characterized by the fact that it comprises, in a cosmetically acceptable aqueous support, at least:

(a) one photoprotective system capable of screening out UV radiation; and

(b) one 2-alkoxy-4-alkyl ketone phenol compound. The present invention also relates to the use of a

2-alkoxy-4-alkyl ketone phenol compound in a composition comprising, in a cosmetically acceptable medium, at least one photoprotective system capable of screening out UV radiation.

It is known that light radiation with wavelengths of between 280 nm and 400 nm permits tanning of the human epidermis and that rays with wavelengths of between 280 and 320 nm, which are known as UV-B rays, cause skin burns and erythema that can harm the development of a natural tan; this UV-B radiation should thus be screened out.

It is also known that UV-A rays, with wavelengths of between 320 and 400 nm, which cause tanning of the skin, are liable to induce impairment thereof, especially in the case of sensitive skin or of skin that is continually exposed to solar radiation. UV-A rays in particular cause a loss of skin elasticity and the appearance of wrinkles, leading to premature ageing. They promote the onset of the erythematous reaction or amplify this reaction in the case of certain individuals, and may even be the cause of phototoxic or photoallergic reactions. It is thus desirable also to screen out UV-A radiation.

Many photoprotective (UV-A and/or UV-B) cosmetic compositions for the skin have been proposed to date. Fluid formulations that afford for the users easy application to skin are most particularly sought. These antisun fluid compositions are quite often in the form of an emulsion of oil-in-water type (i.e. a cosmetically acceptable support constituted of an aqueous dispersing continuous phase and of an oily dispersed discontinuous phase) that contains, in varying concentrations, one or more standard lipophilic and/or hydrophilic organic screening agents capable of selectively absorbing the harmful UV radiation, these screening agents (and the amounts thereof) being selected as a function of the desired sun protection factor, the sun protection factor (SPF) being expressed mathematically as the ratio of the dose of UV radiation required to reach the erythema-forming threshold with the UV-screening agent, to the dose of UV radiation required to reach the erythema-forming threshold without UV-screening agent.

Thus, there is still a significant need to find antisun products that have a sufficiently high protection factor. High protection factors may be reached by incorporating more screening agents in high concentrations. This is not always achievable, despite the addition of large amounts of screening agents. Furthermore, such amounts may result in impairment of the comfort (tacky, coarse effect and/or greasy effect) .

After considerable research conducted in the field of photoprotection mentioned above, the Applicant has now discovered, surprisingly, that the addition of a 2- alkoxy-4-alkyl ketone phenol compound, in a composition containing at least one system for screening out UV radiation, made it possible to increase its photoprotection efficacy and in particular its sun protection factor.

This discovery forms the basis of the present invention .

Thus, in accordance with a first subject of the present invention, novel fluid compositions for protecting the skin and/or hair against ultraviolet radiation are proposed, characterized by the fact that they comprise, in a cosmetically acceptable aqueous support, at least:

(a) one photoprotective system capable of screening out UV radiation constituted by one or more hydrophilic, lipophilic or insoluble organic screening agents and/or one or more metal oxide pigments which may or may not be coated;

(b) at least one 2-alkoxy-4-alkyl ketone phenol compound .

According to the invention, the term

"photoprotective system capable of screening out UV radiation" is generally intended to denote any compound or any combination of compounds which, via mechanisms known per se of absorption and/or reflection and/or scattering of UV-A and/or UV-B radiation, makes it possible to prevent, or at least to limit, the contact of said radiation with a surface (skin or hair) onto which this or these compound (s) have been applied. In other words, these compounds may be UV-absorbing photoprotective organic screening agents or UV- scattering and/or UV-reflecting mineral pigments, and also mixtures thereof.

The term "cosmetically acceptable" means compatible with the skin and/or its integuments, which has a pleasant colour, odour and feel and which does not cause any unacceptable discomfort (stinging, tautness or redness) liable to put the consumer off using this composition.

Yet another subject of the present invention lies in the use of at least one 2-alkoxy-4-alkyl ketone phenol compound in a fluid composition comprising, in a cosmetically acceptable support, at least one photoprotective system capable of screening out UV radiation constituted by one or more hydrophilic, lipophilic or insoluble organic screening agents and/or one or more metal oxide pigments which may or may not be coated, for the purpose of increasing the sun protection factor (SPF) . Other features, aspects and advantages of the present invention will emerge on reading the detailed description that follows.

Preferably, the 2-alkoxy-4-alkyl ketone phenol compounds in accordance with the invention are chosen from those corresponding to the formula (I) below:

in which

- Ri represents a (saturated) linear C ₁ -C ₄ alkyl radical, and preferably methyl or ethyl;

The complementary inorganic screening agents are chosen from coated or uncoated metal oxide pigments for which the mean size of the primary particles is preferentially between 5 nm and 100 nm (preferably between 10 nm and 50 nm) such as, for example, pigments formed of titanium oxide (amorphous or crystalline in the rutile and/or anatase form), of iron oxide, of zinc oxide, of zirconium oxide or of cerium oxide, which are all UV photoprotective agents well known per se.

The pigments may be coated or uncoated.

The coated pigments are pigments that have undergone one or more surface treatments of chemical, electronic, mechanochemical and/or mechanical nature with compounds as described for example in Cosmetics & Toiletries, February 1990, Vol. 105, pp. 53-64, such as amino acids, beeswax, fatty acids, fatty alcohols, anionic surfactants, lecithins, sodium, potassium, zinc, iron or aluminium salts of fatty acids, metal alkoxides (of titanium or of aluminium) , polyethylene, silicones, proteins (collagen, elastin) , alkanolamines , silicon oxides, metal oxides or sodium hexametaphosphate .

In a known way, the silicones are organosilicon polymers or oligomers having a linear or cyclic and branched or crosslinked structure, of variable molecular weight, obtained by polymerization and/or polycondensation of suitably functionali zed silanes and essentially constituted of a repetition of main units in which the silicon atoms are connected to one another via oxygen atoms (siloxane bond) , optionally substituted hydrocarbon radicals being connected directly to said silicon atoms via a carbon atom.

The term "silicones" also encompasses the silanes necessary for their preparation, in particular alkylsilanes . The silicones used for the coating of the pigments suitable for the present invention are preferably chosen from the group containing alkylsilanes , polydialkylsiloxanes and polyalkylhydrosiloxanes. More preferably still, the silicones are chosen from the group containing octyltrimethylsilane, polydimethylsiloxanes and polymethylhydrosiloxanes.

Of course, the metal oxide pigments formed may, before their treatment with silicones, have been treated with other surface agents, in particular with cerium oxide, alumina, silica, aluminium compounds, silicon compounds or mixtures thereof.

The coated pigments are more particularly titanium oxides that have been coated:

- with silica, alumina and aluminium stearate and treated with a silicone, such as the product "STT-30- DS" from the company Titan Kogyo,

- with silica and treated with a silicone, such as the product "UV-Titan X 195" from the company Kemira, or the product "SMT-100 WRS" from the company Tayca,

- with alumina and treated with a silicone, such as the products "Tipaque TTO-55 (S)" from the company Ishihara or "UV Titan M 262" from the company Kemira, - with triethanolamine, such as the product "STT-

65-S" from the company Titan Kogyo,

- with stearic acid, such as the product "Tipaque TTO-55 (C) " from the company Ishihara,

EXAMPLES 1 and 2 :

Antisun formulations containing the following ingredients were prepared.

(*) outside the invention

The aqueous phase A is prepared, which is heated at 80/85°C (cloudy solution) - then the temperature is reduced to around 70°C (68°C) .

The fatty phase Bl is prepared, then it is heated at 68/72°C (72°C - clear) . The phase B2 is added at 68°C.

An emulsion is formed by incorporating the phase B into the phase A over 10 min at 2500 rpm - (microscope: fine and dense emulsion with some large globules) .

At a temperature of 50 °C, the phase C is incorporated into the mixture AB up to 3300 rpm

(blockage of the emulsifier) . It is then moved into a mixer for around 10 min to refine the large globules.

It is cooled using a butterfly shaft to around 40°C.

The phases D, E and F are subsequently added over 10 min .

For each of the compositions 1 and 2, the sun protection factor (SPF) associated therewith was then determined. This was determined by using the in vitro method described by V. Wandel et al . in SOFW Journal 127 (2001); this method consists in determining the monochromatic protection factors over a wavelength range from 290 to 400 nm and in calculating therefrom the sun protection factor according to a given mathematical equation. The measurement was performed with a 1 nm interval on a UV-1000S machine from the company Labsphere, 0.6 mg/cm ² of product being spread onto a frosted PMMA plate. The results (mean value corresponding to 5 plates per product, 10 points per plate) are collated in Table (I) below: Table (I)

The two averages are significantly different at 95% and 99% confidence according to the Student's t- test .
