AQUEOUS PHOTOPROTECTOR COMPOSITION CONTAINING

CONCAVATED POLYACRYLATE PARTICLES AND AT LEAST ONE FILTER

WATER SOLUBLE ORGANIC UV

The present application relates to an aqueous composition comprising, in a physiologically acceptable medium:

a) at least one aqueous phase

b) concave polyacrylate particles, in particular in the form of portions of hollow spheres;

c) at least one water-soluble organic UV filter.

It is well known that light radiations of wavelengths between 280 nm and 400 nm allow the browning of the human epidermis and that rays of wavelengths between 280 and 320 nm, known under the name of UV-B, cause erythema and skin burns which can affect the development of natural tanning; this UV-B radiation must therefore be filtered.

It is also known that UV-A rays, of wavelengths between 320 and 400 nm, which cause browning of the skin, are capable of inducing an alteration thereof, in particular in the case of skin sensitive or skin continuously exposed to solar radiation. UV-A rays cause in particular a loss of elasticity in the skin and the appearance of wrinkles, leading to premature aging. They promote the triggering of the erythematous reaction or amplify this reaction in certain subjects and can even be the cause of photo-toxic or photo-allergic reactions. It is therefore desirable to also filter UV-A radiation.

UVA and UVB rays must therefore be filtered and there are currently cosmetic compositions protecting the human epidermis containing UVA and / or UVB filters in the context of daily and sun photoprotection.

However, one of the major objectives of these applications is, for reasons of cosmetic approval, of tolerance but also for reasons of formulation to limit as much as possible the level of sunscreens in the composition.

In addition, we are looking for light products, without residue on the skin, which is easily applied, in particular by spraying. We are therefore particularly looking for aqueous compositions.

In patent application US-2015-0064224, solar formulations have already been proposed comprising organic UV filters and spherical polymer particles to increase the level of protection. These particles do not make it possible to obtain both an improvement in the sun protection factor of the compositions as well as softfocus properties or to reduce the shine of the skin after application.

We will therefore look for materials, which introduced into the composition not only make it possible to significantly improve the effectiveness of water-soluble sunscreens but without the drawbacks stated above, in particular making it possible to obtain a soft feel after application, a soft focus effect and a matte skin (not shiny).

The Applicant has surprisingly and unexpectedly discovered that this objective can be achieved by using concave polyacrylate particles in an aqueous composition comprising at least one water-soluble organic UV filter.

Furthermore, the applicant has found that these concave polyacrylate particles in an aqueous composition comprising at least one water-soluble organic UV filter, also made it possible to significantly reduce the gloss, after application. They also bring softness to the application as well as a soft-focus effect.

These particles allow the reduction or even elimination of the tacky feel, the optimization of the sliding properties, of spreading, and of comfort of the composition according to the invention.

Thus, the subject of the present invention is an aqueous composition comprising in a physiologically acceptable medium:

a) at least one aqueous phase

b) concave polyacrylate particles, in particular in the form of portions of hollow spheres;

c) at least one water-soluble organic UV filter.

The present invention also relates to the use of concave polyacrylate particles, in particular in the form of portions of hollow spheres in an aqueous composition comprising in a physiologically acceptable medium at least one aqueous phase and at least one water-soluble organic UV filter, in the aim of increasing the effectiveness of protection against UV radiation and in particular the sun protection factor (SPF).

The present invention also relates to the use of concave polyacrylate particles, in particular in the form of portions of hollow spheres in an aqueous composition comprising in a physiologically acceptable medium at least one aqueous phase and at least one water-soluble organic UV filter, in the purpose of reducing the gloss after application.

The present invention also relates to the use of concave polyacrylate particles, in particular in the form of portions of hollow spheres in an aqueous composition comprising in a physiologically acceptable medium at least one aqueous phase and at least one water-soluble organic UV filter, in the purpose of bringing softness to the application on the skin.

The term “physiologically acceptable medium” means a non-toxic medium capable of being applied to the skin, the lips, the hair, the eyelashes, the eyebrows, the nails. The composition of the invention may especially constitute a cosmetic or dermatological composition.

The sun protection factor (SPF) is expressed mathematically by the ratio of the dose of UV radiation necessary to reach the erythematogenic threshold with the UV filter with the dose of UV radiation necessary to reach the erythematogenic threshold without UV filter.

The term "aqueous composition" means a composition comprising at least 2% by weight of water relative to the weight of the composition.

By mean diameter is meant the largest dimension of the particle.

Advantageously, these particles have a density greater than 1.

Preferably, the hemispherical hollow particles comprise or consist of homopolymers or copolymers of (meth) acrylic acid or of their C1-C4 esters, such as C1-C4 alkyl acrylate or methacrylate, in particular methyl acrylate or methacrylate or ethyl, preferably crosslinked.

By “radical polymerization” is meant a polymerization of at least one ethylenic monomer such as (meth) acrylic acid or their C1-C4 esters, such as C1-C4 alkyl acrylate or methacrylate, in particular acrylate or methacrylate of methyl or ethyl.

The particles comprise at least a concave part and at least a convex part, more particularly the particles have a hollow hemispherical shape, that is to say of the "bowls" type.

The particles in the form of “bowls” can comprise or consist of PMMA.

Particles in the form of “crosslinked polymethyl methacrylate (PMMA) bowls are in particular the MICROPEARL® M310 sold by the company SEPPIC.

The inorganic UV filters are chosen from pigments (average size of the primary particles: generally between 5 nm and 100 nm, preferably between 10 nm and 50 nm) of metallic oxides coated or not, such as for example titanium oxide pigments (amorphous or crystallized in rutile and / or anatase form), iron, zinc, zirconium or cerium which are all UV photoprotective agents well known per se.

By "inorganic UV filter" is meant any non-organic chemical molecule capable of absorbing and / or physically blocking (in particular reflection or diffraction) UV radiation in the wavelength range between 280 and 400 nm.

Pigments can be coated or uncoated.

The coated pigments are pigments which 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, p. 53-64, such as amino acids, beeswax, fatty acids, fatty alcohols, anionic surfactants, lecithins, sodium, potassium, zinc, iron or aluminum salts of fatty acids, metal alkoxides (titanium or aluminum), polyethylene, silicones, proteins (collagen, elastin), alkanolamines, silicon oxides, metal oxides or sodium hexametaphosphate.

In known manner, silicones are organosilicon polymers or oligomers with linear or cyclic, branched or crosslinked structure, of variable molecular weight, obtained by polymerization and / or polycondensation of suitably functionalized silanes, and essentially consisting of a repetition of main units in which the silicon atoms are linked together by oxygen atoms (siloxane bond), optionally substituted hydrocarbon radicals being directly linked via a carbon atom on said silicon atoms.

The term silicones also includes the silanes necessary for their preparation, in particular, the alkyl silanes.

The silicones used for coating the pigments suitable for the present invention are preferably chosen from the group containing alkyl silanes, polydialkylsiloxanes, and polyalkylhydrogenosiloxanes. Even more preferably, the silicones are chosen from the group containing octyl trimethyl silane, polydimethylsiloxanes and polymethylhydro-genosiloxanes.

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

The coated pigments are more particularly coated titanium oxides:

The protocol for preparing the compositions is as follows: Preparation of phase A

The raw materials are carefully weighed beforehand using a balance (precision = 0.01 g), and are mixed using a Rayneri mixer.

Phase B

Phase B is introduced into phase A with stirring using a Rayneri mixer until a homogeneous preparation is obtained.

Addition of phase C

Phase C is introduced into phase A + B with stirring using a Rayneri mixer.

Phase D

Phase D is introduced into phase A + B + C with Rayneri stirring.

Then, the mattness, the smoothness on application and the soft focus were evaluated according to the following protocols:

In vitro SPF measurement

The sun protection factor (SPF) is determined according to the "in vitro" method described by B.L. Diffey in J. Soc. Cosmet. Chem. 40, 127-133, (1989).

The measurements were carried out using a UV-1000S spectrophotometer from the company Labsphere. Each composition is applied to a quartz slide, in the form of a homogeneous and regular deposit at the rate of 1.33 mg / cm2.

Gloss rating

Gloss is measured using a BYK-Gardner gloss meter at an angle of 60 °. Each composition is spread over a contrast card. The thickness of the wet film obtained is 100 μm. The film is dried in an incubator at 37 ° C at 50% humidity for 24 hours. The measurement is made on the black part of the contrast card and reproduced 3 times per composition.

Evaluation of softness on application, and of the soft focus effect

The softness on application, and the soft focus effect (blur) are evaluated by a panel of sensory experts of 10 people. Each composition is applied to the forearm with a dose of 2 mg / cm2. The product is spread in circular movements until the product penetrates (about 30 seconds). The softness evaluation is carried out during the application. The soft focus effect is evaluated after 2 minutes of drying:

Soft focus - Softness effect: The soft focus effect is evaluated by eye after 2 minutes of drying.

It is found that the SPF is significantly improved when hollow hemispherical particles are added to the reference composition. In vitro SPF is improved by 60% by adding hemispherical polyacrylate particles according to the invention, while SPF is improved by only 40% with spherical particles.

In addition, these hemispherical particles make it possible to significantly reduce the shine, after application, and to provide softness on application and a soft-focus effect after application.
