Description

The present invention relates to cosmetic compositions intended for the photoprotection of the skin and / or the hair against ultraviolet radiation, in particular solar radiation, having in particular improved water retention, these compositions comprising at least one anti-ultraviolet filter. And UV and at least one polymer chosen from hyperbranched polymers and dendrimers. The invention also relates to the use of hyperbranched polymers and dendrimers to improve, in particular, the water retention of antisolar compositions containing anti-UV filters.

It is known that light radiation of wavelengths between 280 nm and 400 nm allows the browning of the human epidermis and that the wavelength rays between 280 nm and 320 nm, known under the name of UV -B, cause erythema and skin burns that 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 nm and 400 nm, which cause browning of the skin, are capable of inducing an alteration thereof, particularly in the case of sensitive skin or skin continuously exposed to solar radiation. UV-A rays cause in particular a loss of elasticity of the skin and the appearance of wrinkles leading to premature aging. They promote the triggering of the erythematous reaction or amplify this reaction in some subjects and may even be the cause of phototoxic or photoallergic reactions. It is therefore desirable to also filter the UV-A radiation.

Numerous cosmetic and / or dermatological compositions intended for the photoprotection (UV-A and / or UV-B) of the skin have been proposed to date.

These antisolar compositions are quite often in the form of an emulsion, of the oil-in-water type (ie a cosmetically and / or dermatologically acceptable support consisting of an aqueous dispersant continuous phase and a discontinuous phase. dispersed oily) or water-in-oil (aqueous phase dispersed in a continuous oily phase), which contains, in various concentrations, one or more conventional organic filters, lipophilic and / or hydrophilic, capable of selectively absorbing harmful UV radiation , these filters (and their quantities) being selected according to the desired sun protection factor (the sun protection factor (SPF) expressed mathematically by the ratio of the irradiation time required to reach the erythematogenic threshold with the UV filter at time required to reach the erythematogenic threshold without UV filter). In such emulsions, the hydrophilic filters are present in the aqueous phase and the lipophilic filters are present in the fatty phase.

The oil-in-water emulsions are, in general, more appreciated by the consumer than the water-in-oil emulsions, in particular because of their pleasant touch (close to water) and their presentation in the form of water. milk or non-fat cream; however, they also lose their effectiveness in UV protection when they come into contact with water; indeed, hydrophilic filters, including acids, disappear with water, by swimming in the sea or in the pool, in the shower or when practicing water sports; thus, the sunscreen compositions which contain them, alone or in combination with the lipophilic filters, no longer provide the initial protection sought, since the substrate (skin or hair) to which they have been applied comes into contact with the water, this loss in protection index by water elimination of the hydrophilic filter being all the more marked that the filtering association lipophilic hydrophilic, present in the composition, is synergistic in terms of sun protection factor.

Sunscreen compositions having improved SPF and water resistance can be provided using water-in-oil emulsions. Indeed, a hydrophilic filter is more remanent to water in a water-in-oil emulsion than in an oil-in-water emulsion. However, as indicated above, such compositions are not yet entirely satisfactory insofar as they leave after application a greasy impression particularly unpleasant for the user.

It is known, in particular from documents EP-A-272719, JP-05-032532 and FR-A-2706766, that the addition of certain lipophilic amino compounds makes it possible to increase the water permeability of the water-soluble acidic filters.

Patent Application EP-A-0275719 sought to render substantive and water-resistant compositions comprising solar filters acid, associating them with a fatty amine.

This type of solution is in some cases unsatisfactory because of the impossibility of combining certain acidic filters with fatty amines and also because the fatty amines can cause contact allergies as described in the book "Adverse reactions to cosmetics "(Anton de Cornelis de Groot - Ed.

Rijksuniversiteit Groningen, 1988) Chapter 5, p. 170 and following.

JP-05-032532 and FR-A-2706766 describe the use of amino silicones in sunscreen compositions. However, it has been found that amino silicones with a high acid number are difficult to formulate: in the presence of a water-soluble filter, they form precipitates. On the other hand, amino silicones of low acid number must be used in large quantities to produce a significant effect, which has a toxicological risk and can affect the stability of the formula.

The applicant has now discovered a new cosmetic composition using an ultraviolet radiation filtering agent overcoming the drawbacks of the prior art and also having improved water retention.

The improvement of these properties is particularly advantageous in the case of solar compositions in the form of oil-in-water emulsions.

The present invention thus firstly relates to a cosmetic filtering composition, characterized in that it comprises, in a cosmetically acceptable support, at least one ultraviolet radiation filtering agent and at least one polymer chosen from hyperbranched polymers and dendrimers.

Hyperbranched polymers are molecular constructs with a branched structure, usually around a heart. Their structure is generally devoid of symmetry: the basic units or monomers used for the construction of hyperbranched polymer may be of different types and their distribution is irregular. The branches of the polymer may be of different natures and lengths. The number of basic units, or monomers, may be different depending on the different branches.

While being asymmetrical, hyperbranched polymers may have: an extremely branched structure, around a heart, successive layers or generations of branches, a layer of terminal chains.

The hyperbranched polymers are generally derived from the polycondensation of one or more ABx monomers, A and B being reactive groups capable of reacting together, where x is an integer greater than or equal to 2, but other methods of preparation can be envisaged. The hyperbranched polymers are characterized by their degree of polymerization DP = 1-b, b being the percentage of non-terminal functional groups of B which have not reacted with a group A. The condensation being non-systematic, contrary to the synthesis dendrimers, the degree of polymerization is less than 100%. In the usual way, by known synthesis methods, DP is between 15 and 90%. A terminal group T may be reacted on the hyperbranched polymer to obtain a particular function at the end of chains.

Such polymers are described in particular in B.I.Voit, Acta Polymer., 46, 87-99 (1995); EP-682059; WO-9614346; WO-9614345 WO-9612754.

Several hyperbranched polymers can be associated with each other, by a covalent bond or another type of bond, through their terminal groups. Such so-called bridged or bridged polymers fall within the definition of hyperbranched polymers according to the present invention.

Certain hyperbranched polymers, in particular those having regular branching, although not formed by regular sequential addition of base units, give particularly interesting results in the compositions according to the present invention.

Dendrimers are highly branched polymers and oligomers, also known per se, having a well-defined chemical structure, and are said to be perfect hyperbranched polymers. Generally, dendrimers include a core, a specified number of generations of branches, or spindles, and terminal groups. Generations of spindles consist of structural units, which are identical for the same generation of spindles and which may be identical or different for different generations of spindles. Generations of spindles extend radially in a geometric progression from the heart. The terminal groups of a nth generation dendrimer are the terminal functional groups of the Nth generation or terminal generation spindles. Such polymers are described in particular in DATomalia, AMNaylor and WAGoddard III,
Angewandte Chemie, lnt.Ed.Engl 29 138-175 (1990); CJHawker and JMJFrechet, J.Am.Chem.Soc., 112, 7638 (1990), BlVoit, Acta Polymer., 87-99 (1995), N.Ardoin and D.Astruc, Bull. Soc. Chim. Fr. 132, 875-909 (1995).

Dendrimers can also be defined more particularly by the following formula (Dl)
C [A1B1 (A2B2 (... (An-1 Bn-1 (AnBn (T) rn-1) rn-2 ...) r2) r] S (D1) in which
C represents the heart, connected by a number of functionalities to its time zones A1B1
through the groupings A;
- s is an integer greater than or equal to 1 and less than or equal to the number of
C features;
The index i (i = 1, 2 .... n) is an integer which designates the generation of each
time;
rj (i = 1, 2 n-1) represents the number of functionalities of the group B1
belonging to the spindle (A1B1), where ri is an integer greater than or equal to 2 - for each spindle (AiBi) (i = 1, 2 n), the group Bj is connected to r
groups Aj + 1 of a spindle (Aj + Bj + 1);
each grouping Aj (i 2 2) is connected to a single group Bj.1 of the spindle (to 1 B1.1)
the nth generation spindle AnBn is chemically related to a number rn of
terminal groups T, rn being an integer greater than or equal to zero.

The definition of the dendrimers given above includes molecules with symmetrical branches; it also includes non-symmetric branching molecules, such as, for example, dendrimers whose spindles are lysine groups, in which the branching of a spindle generation on the preceding one is done on amines a and E of lysine, which leads to a difference in the length of the spindles of the different branches.

Dense star polymers, starburst polymers, rod dendrimers, or rod-shaped dendrimers are included in the present definition of dendrimers. The molecules called arborols and molecules in cascade also fall within the definition of the dendrimers according to the present invention.

Several dendrimers may be associated with each other, by covalent bonding or other type of bonding, through their terminal groups to give entities known as bridged dendrimeres, dendrimer aggregates or bridged dendrimer. Such entities are included in the definition of the dendrimers according to the present invention.

Dendrimers may be in the form of a set of molecules of the same generation, called monodisperse sets; they can also be in the form of sets of different generations, called polydisperses. The definition of the dendrimers according to the present invention includes monodisperse as well as polydisperse sets of dendrimers.

The invention more particularly relates to hyperbranched polymers with amino end groups and dendrimers with amino terminal groups.

Preferably, in particular for reasons of solubility, their terminal groups carry a primary amine function.

Reference may be made to the following documents in which dendrimers whose terminal group includes an amine function are described, the content of these documents being incorporated by reference in the present description: US-4,694,064, US-4,507,466; U.S. 4,631,337; US 4,558,120; US-4,568,737, US-4,587,329; WO-A-9502008; WO-A9314147; EP-234408, US-4,289,872, US-4,360,646, Proc. Natl. Acad. Sci. USA, 5409-5413 (1988).

The dendrimers containing amine end groups are, for example, polyamidoamines, for example those sold under the trademark STARBURST PAMAM by the company DENDRITECH (block copolymers of ethylene diamine and of methyl acrylate). They can also be chosen from polyalkylamine type dendrimers, for example polyethyleneimines and polypropyleneimines manufactured by DSM.

The hyperbranched polymers and the dendrimers with amino end groups may also consist of a core and generations of base units, monomers or spindles, of all kinds, on which a terminal group T carrying an amine function has been grafted. .

Preferably, the polymer is selected from dendrimers.

The invention relates more particularly ultraviolet filtering agents of the hydrophilic type, more particularly those comprising at least one organic acid radical.

The present invention more particularly but not exclusively targets hydrophilic filters containing at least one sulfonic radical -SO3H. However, it also applies to compositions containing hydrophilic filters containing carboxylic radicals.
