Description

Title of the invention: COMPOSITION COMPRISING AT LEAST ONE AMPS® COPOLYMER, AT LEAST ONE ALKYL(POLY)GLYCOSIDE, AT LEAST ONE UV FILTER AND ISOPROPYL MYRISTATE

[0001] The present invention relates to a cosmetic or dermatological composition in the form of an emulsion comprising in a physiologically acceptable support at least one aqueous phase, at least one oily phase, at least one copolymer comprising at least one monomer of 2-acrylamido-2-methylpropane sulfonic acid (AMPS®) and at least one monomer with a hydrophobic group, at least one emulsifying system comprising at least one alkyl(poly)glycoside, at least one UV filter, and isopropyl myristate. technical field

[0002] In the cosmetic field, more and more consumers are looking for cosmetic products not only intended for the care of keratinous materials, but also possessing a photoprotective activity of keratinous materials, while remaining very demanding in terms of sensory qualities and performance of these products.

[0003] It is indeed well known that light radiation with wavelengths between 280nm and 400nm causes browning of the human epidermis and that rays with wavelengths between 280 and 320nm, known as UV-B, cause erythema and skin burns; this UV-B radiation must therefore be filtered.

[0004] It is also known that UV-A rays, with wavelengths between 320 and 400 nm, which cause skin tanning, are likely to induce skin damage, particularly in the case of sensitive skin or skin continuously exposed to sunlight. UV-A rays specifically cause a loss of skin elasticity and the appearance of wrinkles, leading to premature aging. They promote the onset of the erythematous reaction or amplify this reaction in some individuals and can even cause phototoxic or photoallergic reactions. It is therefore advisable to also filter UV-A radiation.

[0005] UVA and UVB rays must therefore be filtered and there are currently cosmetic compositions that protect the human epidermis and contain UVA and UVB filters.

[0006] Keratin treatment compositions comprising at least one UVA and / or UVB filter are generally in the form of an emulsion, of the type oil-in-water (i.e. a cosmetically and / or dermatologically acceptable carrier consisting of a continuous aqueous dispersing phase and a discontinuous dispersed oily phase) or water-in-oil (aqueous phase dispersed in a continuous oily phase), which contains, at various concentrations, one or more conventional liposoluble organic filters and / or conventional water-soluble organic filters 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) being mathematically expressed by the ratio of the dose of UV radiation necessary to reach the erythematogenic threshold with the UV filter to the dose of UV radiation necessary to reach the erythematogenic threshold without a UV filter.In such emulsions, hydrophilic filters are present in the aqueous phase and lipophilic filters are present in the oily phase. Multiple emulsions also exist, obtained after dispersing an inverse emulsion in an aqueous phase.

[0007] The use of certain organic filters in these keratin-based skincare emulsions tends to impair their sensory qualities, both when the composition sets in the jar (when the formulas are packaged in this way) and when applied to the skin. Thus, the presence of organic UV filters leads, in particular, to less smooth application and a greater transformation of the texture into an oil. Furthermore, the skin finish is also altered by the presence of such filters, resulting in formulas that are more waxy (with a rougher skin finish) and more sticky (with a stickier skin finish).

[0008] The object of the present invention is therefore to have a specific combination of raw materials allowing the formulation of care compositions for keratinous materials in the form of emulsions with the implementation of UV filters, in particular organic ones, without the disadvantages stated above.

[0009] This need is all the more pressing given the rapid expansion of the daily sun protection market. An increasing number of hybrid products offering both skincare and SPF 15-20 protection are being launched, but the challenge remains of providing a pleasant sensory experience for daily application. The skincare sector remains very different from the sun protection sector in terms of consumer experience, particularly with products sold in jars, which increases the complexity of formulation development.

[0010] We therefore seek to have a product with SPF while retaining the sensory codes of skin care: Appearance, texture, consistency, sensory.

[0011] In other words, the aim of the invention is to develop a product with an appealing sensory experience, in particular with a soft, non-sticky skin finish and good spreading properties (glide and limited oil transformation), allowing for a photo daily protection and which can be marketed in packaging classically used in the field of skin care, including a formulation in a jar.

[0012] The present invention is specifically designed to meet these needs. Description of the invention

[0013] The present invention relates to a cosmetic or dermatological composition in the form of an emulsion comprising, in a physiologically acceptable carrier:

[0014] a) at least one aqueous phase

[0015] b) at least one oily phase

[0016] c) at least one copolymer comprising at least one monomer of 2-acrylamido-2-methylpropane sulfonic acid (AMPS®) and at least one monomer with a hydrophobic group, the monomer with a hydrophobic group of formula (II) being ethoxylated stearyl methacrylate (25OE) corresponding to the compound of formula (II):

[0017] in which the Ri group represents a methyl group, the Y group designates O, the R2 group represents an alkyl radical comprising 18 carbon atoms and x is equal to 25

[0018] d) at least one emulsifying system comprising at least one alkyl(poly)glycoside.

[0019] e) at least one UV filter, and

[0020] f) of isopropyl myristate.

[0021] The present invention also relates to a cosmetic treatment process for keratinous materials in which a composition as defined above is applied to said keratinous materials.

[0022] The invention also relates to the use of a composition as defined above for the cosmetic treatment of keratinous materials.

[0023] Contrary to expectations, the inventors found that an emulsion composition comprising at least one AMPS® copolymer in association with at least one emulsifying system comprising at least one alkyl(poly)glycoside, at least one UV filter and isopropyl myristate has improved spreading, softness to the touch and / or non-sticky qualities.

[0024] The invention is not limited to the illustrated examples. The features of the different examples can, in particular, be combined within non-illustrated variants.

[0025] The expression "comprising one" should be understood as meaning "comprising at least one", unless otherwise specified.

[0026] The expressions "at least one" and "at least" used in this description are respectively equivalent to the expressions "one or more" and "greater than or equal to".

[0027] By "keratinous materials" according to the invention, we mean the skin of the body, face and / or around the eyes, the lips, nails, mucous membranes, eyelashes, eyebrows, hair, scalp and / or head hair, or any other cutaneous area of ​​the body. More particularly, the keratinous materials according to the invention are the scalp, the hair, and / or the skin.

[0028] Preferably, the keratinous materials according to the invention are skin.

[0029] By "skin" we mean the entire skin of the body, and preferably the skin of the face, décolletage, neck, arms and forearms, or even more preferably the skin of the face, in particular the forehead, nose, cheeks, chin, eye contour.

[0030] By "copolymer" we mean both copolymers obtained from two kinds of monomers and those obtained from more than two kinds of monomers such as terpolymers obtained from three kinds of monomers.

[0031] For the purposes of the present invention, the following definitions apply:

[0032] - "SP F" (Sun Protection Factor in English): the sun protection factor, which measures the level of protection against UVB rays. The SPF value corresponds to the ratio between the minimum time it takes to get a sunburn with a sunscreen and that without the product. More precisely, the term "SPF" is defined in the article "A new substrate to measure sunscreen protection factors throughout the ultraviolet spectrum," J. Soc. Cosmet. Chem., 40, 127-133 (May / June 1989).

[0033] The SPF (Sun Protection Factor) can be evaluated in vitro using the Labsphere® spectrophotometer. The plate is the material onto which the sunscreen composition is applied. For this protocol, polymethyl methacrylate (PMMA) plates have proven ideal.

[0034] The evaluation of the Sun Protection Factor (SPF) of the compositions can also be carried out in-vivo according to the ISO / EN 24444 protocol “Cosmetics-Sun protection test methods: In-vivo determination of the sun protection factor (SPF) (2010)”.

[0035] - "PPD" (Persistent Pigment Darkening): the index characterizing UVA protection. In particular, the "PPD" measures skin color observed 2 to 4 hours after UVA exposure. This method has been adopted since 1996 by the Japanese Cosmetic Industry Association (JCIA) as the official testing procedure for UVA labeling of products and is frequently used by testing laboratories in Europe and the United States; (Japan Cosmetic Industry Association Technical Bulletin. Measurement Standards for UVA protection efficacy. Issued November 21, 1995 and effective of January 1, 1996).

[0233] According to a particular embodiment of the invention, the composition is free of octocrylene. "Free of octocrylene" means a composition containing less than 1% by weight, or even less than 0.5% by weight relative to the total weight of the composition, of octocrylene. Octocrylene has been used in the past both as a sunscreen and as a solvent to improve the solubility of other sunscreens such as triazine derivatives, thereby reducing the stickiness of compositions containing such filters. However, there is a consumer expectation for cosmetic compositions containing sunscreens that have a pleasant sensory experience, are non-sticky, but are free of octocrylene.

[0234] Organic UV filters may be present in the composition according to the invention at a content ranging from 0.05% to 20% by weight, preferably from 0.1% to 15% by weight, and even more preferably from 0.5% to 10% by weight relative to the total weight of the composition. Additional UV filters

[0390] Control of sensory and cosmetic properties:

[0391] For each of the following compositions, the cosmetic properties were evaluated according to the following protocol.

[0392] The cosmetic properties upon application are evaluated monadically by a panel of experts trained in describing skincare products. The sensory evaluation of the skincare products by this panel is carried out as follows: the products are packaged in jars. During the same session, the samples are presented in random order to each panelist. They first evaluate the grip and flexibility in the jar (pick-up). They then place a drop of product (0.05 mL) on the back of their hand and evaluate the glide upon application, followed by the transformation of the texture into an oil by making 15 rotations in 15 seconds with their index and middle fingers. The experts then evaluate the comfort, which is defined by the oily film (more or less oily or waxy on the skin) and the softness after a few seconds of absorption.

[0393] The descriptors are evaluated on a scale rated from 1 to 5: 1 = not, 2 = little, 3 = moderately, 4 = quite, 5 = very.

[0394] The sensory parameters evaluated for the compositions tested are as follows:

[0395] - "Pick-up" (or grip firmness): this parameter allows evaluation of the character The composition (1) should be flexible / stringy or thick / bouncy (5) when set in the pot. For compositions according to the invention, a balanced firmness at setting is expected (neither too flexible / stringy nor too thick / bouncy).

[0396] - Spreading: this property is measured through the following 2 parameters: the Slipperiness upon application and transformation into oil. Regarding slipperiness upon application, this ranges from least slippery (1) to most slippery (5). For the compositions according to the invention, it is expected that the slipperiness will be as high as possible. Regarding transformation into oil, this ranges from a completely non-transformative texture (referred to as "continuous") (1) to a significant transformation into oil (5). For the compositions according to the invention, it is expected that they will not have highly transformative textures.

[0397] - The "skin finish": this property is measured through the 2 parameters The following are considered: oiliness (greasy / waxy) and softness (sticky / smooth). Oiliness ranges from oily (1) to waxy (5). For compositions according to the invention, the oiliness is expected to be as oily as possible to avoid a rough skin finish. Softness ranges from sticky (1), which imparts a tacky feel, to smooth (5). For compositions according to the invention, the smoothness is expected to be as minimally sticky as possible (and therefore the composition should be as minimally sticky as possible after application).

[0398] The results obtained for the different compositions tested are presented in Table 2 below. Only compositions 1 and 4 according to the invention make it possible to obtain the expected firmness upon setting, spreading and skin finish.
