Description

<Desc / Clms Page number 1>

 Cosmetic compositions containing fibers.

The present invention relates to cosmetic compositions or formulations comprising fibers based on a synthetic or artificial polymer.

 The term "composition or cosmetic formulation" is intended to mean all cosmetic products or preparations such as those described in Annex 1 ("Illustrative List by Category of Cosmetic Products") of European Directive 76/768 / EEC of 27 July 1976, so-called cosmetic directive.

The cosmetic compositions may be formulated into a large number of types of skin and hair products, such as foams, gels (hair styling in particular), masks for the skin or hair, conditioners, formulations for improving the appearance of the skin. styling or to facilitate combing, disentangling of the hair, to bring volume or shine, rinsing formulas, lotions and oils for the hands and the body, products improving the hydration of the skin, milks cleansing compositions, sun protection creams or lotions and ultraviolet radiation, care and / or treatment milks and creams, anti-acne preparations, local analgesics, mascaras, products intended for be applied to the lips or other mucous membranes, sticks, deodorant and antiperspirant products, shaving lotions, bath oils, talcs and many other compositions of the same type.

 Among the products that can be used, there are known powders made of synthetic or artificial polymers such as polyamides, polyesters, polyethylenes, etc. These powders can for example be used as an abrasive agent for cleaning the skin. . They can also be used to impart a particular texture to the compositions or formulations.

 These powders give the compositions interesting properties. The uses that are made of it, however, remain limited. Their price is more generally high.

 The object of the present invention is to propose novel compositions or cosmetic formulations, containing a product that can be used as a replacement for or in addition to other products. The product can be used in particular as a replacement for or in addition to powders based on synthetic or artificial polymers. The product can furthermore confer on the compositions or formulations, in a simple manner, properties that were difficult or even impossible to obtain otherwise.

<Desc / Clms Page number 2>

 For this purpose, the invention provides a cosmetic composition containing fibers based on a synthetic or artificial polymer with a titre of between 0.1 and 40 dtex and a length of between 0.1 and 1.5 mm.

 The fibers present in the cosmetic composition may have several functions within said composition.

 They can provide reinforcement functions for films formed on biological surfaces. They can impart to said composition emollient and conditioning properties and can thus at least partially replace the usual emollients or conditioners, especially the usual silicone oils and functional polymers. They can give the cosmetic composition abrasion properties replacing or complementing the polymer powders usually used.

 The fibers can be used to modulate the rheology and texture of the compositions. The presence of the fibers induces for example an increase in viscosity. The fibers are also easily incorporated into the compositions.

 The fibers can be used to modulate the applicability of the composition, giving it increased hiding power. In the context of compositions intended to be rinsed after application to the skin and / or the hair, the presence of the fibers may also facilitate the rinsing and the total or partial elimination of the composition.

 In the context of compositions intended to be used in the form of creams, the fibers can modulate the elasticity of the layer of material applied to the skin and / or strengthen the skin while maintaining an aerated network. The breathability of the skin is improved.

 The fibers contained in the compositions according to the invention are based on a synthetic or artificial polymer. It may be a single polymer, or a composition comprising a synthetic or artificial polymer. It may for example be a mixture of polymers, or a mixture comprising a synthetic or artificial polymer and organic or inorganic additives.

 The fibers are obtained by spinning filaments through a die, then by cutting the resulting filaments. The spinning processes of synthetic or artificial polymers, or polymer compositions, are known. In particular, melt spinning, used for polymers or thermoplastic compositions, or wet spinning generally used for spinning artificial polymers (solution spinning) is mentioned.

The manufacture of fibers may comprise all the steps generally used, such as sizing, stretching, thermo-fixing, relaxation ...

<Desc / Clms Page number 3>

 The fibers generally have a circular cross section, but may have sections of different shapes. It may be, for example, flat, triangular or trilobed sections. The shape of the section has an influence on the visual appearance of the composition, before and / or after application to the skin or the hair. We can thus obtain interesting visual effects, for example glosses or chandeliers more or less important.

 The fibers are of title between 0.1 and 40 dtex. As an indication, it is mentioned that in the case of circular section of fibers consisting of a material whose density is substantially equal to 1 (this is the case of polyamides 6 and 66), a title of about 0.6 dtex corresponds to a diameter of about 7.7 μm. The fiber content is preferably between 0.5 and 2 dtex.

 The length of the fibers is between 0.1 and 1.5 mm. It is preferably between 0.1 and 0.6 mm.

 Fibers based on thermoplastic polymers or thermoplastic compositions are particularly preferred. By way of example, mention may be made of polypropylene, polyethylene terephthalate, polyamide 6 and polyamide 66-based fibers, mixtures or copolymers based on these polymers.

 The polyamide-based 6 or polyamide-66 fibers have a high degree of hydrophilicity which makes it possible to obtain high compatibility in aqueous compositions.

They also provide a particularly good control of skin hydration over time, in the context of use as a cream or deodorant.

The fibers may include additives to the polymers mentioned above. It may also be: - stabilizing additives such as antioxidants, protective
UV, eg phosphite derivatives, hindered phenols, sterically hindered amines for light stabilization (HALS).

 additives intended to modify their appearance, for example pigments, dyes or dyeing agents, additives intended to modify certain characteristics of the polymer, such as hydrophilicity or antistaticity, or to confer new ones on it, example a bio-activity.

 The fibers may comprise inorganic particles based on titanium dioxide or zinc oxide. Compositions comprising such fibers protect the skin from ultraviolet rays. The fibers may for this purpose be used in addition to or in replacement of anti-UV agent usually used. Fibers comprising

<Desc / Clms Page number 4>

 Particles based on titanium dioxide also have a matt appearance that can be sought after. In the case of the use of titanium dioxide-based particles, the concentration by weight of particles in the fibers is generally between 0.02% and 5%, preferably between 0.3 and 1.8%.

 The fibers may comprise color pigments. Such pigments can be mixed with the polymer before the spinning operation. We often speak of fibers "tintmasse". The fibers may also have been dyed in a dye solution. Dyeing of man-made fibers is known.

 The polyamide-based fibers 6 or 66 have a very high dye affinity. It is notably significantly superior to that of powders based on polyamide, or another polymer. The compositions containing polyamide-based dyed fibers exhibit particularly interesting coloring and visual effects. It is advantageous to use dyed polyamide-based fibers in compositions intended to be used as make-up, for example foundations, make-ups, masquarats, etc.

 The fibers may comprise a bioactive agent comprising at least one element chosen from among silver, zinc and copper. These elements may be present in the bioactive agent in metallic form, in ionic form or in the form of a chemical compound, for example in the form of an oxide or hydroxide. The bioactive agent may for example be a mineral compound comprising silver and / or zinc. Examples of agents that may be used are inorganic particles comprising a titanium dioxide core, a layer of a silver and / or zinc compound around the core, and a protective layer. silica base. Such an agent is, for example, described in US Pat. No. 5,180,585. Zeolite-based particles or zirconium phosphates comprising a compound of silver and / or zinc ions are also mentioned.

 The bioactive agent confers particular properties on the composition. It may be a bactericidal or bacteriostatic action and / or an anti-fungal action. These properties have a dual interest: Protect the composition against the development of bacteria and / or fungi within it, prevent the development and / or proliferation of bacteria and / or fungi on the surface of the skin and / or hair, where the cosmetic composition is applied. The prevention of the proliferation of bacteria makes it possible in particular to avoid the development of bad odors.

The use of fibers comprising a bioactive agent is therefore particularly advantageous in the context of the preparation of deodorants.

 The fibers may comprise an agent, added to the synthetic or artificial polymer, for modifying the hydrophilicity and / or antistaticity of the polymer. Polymers

<Desc / Clms Page number 5>

 are advantageously thermoplastic polymers as described above.

According to another embodiment, the polymer is a copolymer comprising patterns intended to modify the hydrophilicity and / or the antistaticity. Such a copolymer is obtained by copolymerization of said units in the presence of precursors of the synthetic or artificial polymer. According to a preferred embodiment, an agent or units comprising polyethylene glycol units is used. The fibers may for example be obtained from a mixture of polyamide 6 or 66 and a polymer selected from polyethylene glycol, polyamide-polyethylene glycol copolymers, polyether-block-amide block copolymers. They can also be obtained from a copolymer obtained from the monomers of polyamides and polyoxides of ethylene diamines (for example marketed by Hunstman under the name Jeffamine range).

 The amounts of fibers present in the cosmetic composition which is the subject of the invention depend on the desired function and the type of cosmetic formulation considered. Those skilled in the art are able to determine these quantities.

As an indication, mention may be made of the mass quantities of fibers favorably present in the cosmetic composition as a function of the desired application. skincare products (creams, milks) 0.5-5% make-up removers 1-2% body products 0.5-1, 5% products for phaneres 0.5-30% make-up products up to 30% hygiene and hygiene products (deodorants, 1-10% antiperspirants, shaving products and hydroalcoholic products) solar products (cream, milk, oil) up to 99%, preferably 10-40% hair products (shampoo, after shampoo) Up to 5% (hair care, hair enhancer) Up to 10%

Humectants may also be incorporated into the cosmetic compositions which are the subject of the invention, glycerol, sorbitol, urea, collagen, gelatin, aloe vera, hyaluronic acid and the like. emollients which are generally selected from alkylmonoglycerides, alkyldiglycerides, triglycerides such as oils extracted from plants and plants (palm, coconut, cottonseed, soybean, sunflower, olive, grapeseed oils) , sesame, peanut, castor oil ...) or oils of animal origin (tallow, fish oils ...), derivatives of these oils such as hydrogenated oils, lanolin derivatives, oils paraffinic oils, perhydrosqualane, squalene, diols such as 1-2-propanediol, 1,3-butandiol, cetyl alcohol, stearyl alcohol, oleic alcohol, polyethylene glycols or polypropylene glycols, fatty esters such as isopro palmitate pyl, ethyl-2-hexyl cocoate, myristyl myristate, lactic acid esters, stearic acid, behenic acid, isostearic acid.

To further reduce the irritation or aggression of the scalp, it is also possible to add water-soluble or water-dispersible polymers such as collagen or certain non-allergenic derivatives of animal or vegetable proteins (hydrolysas of wheat proteins, for example), natural hydrocolloids ( guar gum, carob, tara, etc.) or from fermentation processes and the derivatives of these polycarbohydrates, such as modified celluloses (for example hydroxyethylcellulose, carboxymethylcellulose), guar or carob derivatives and their cationic derivatives. or nonionic derivatives (eg hydroxypropylguar), anionic derivatives (carboxymethylguar and carboxymethylhydroxypropylguar).

To these compounds, it is possible to add, in combination, powders or mineral particles such as calcium carbonate, inorganic oxides in the form of powder or in colloidal form (particles of smaller size or of the order of a micrometer, sometimes of some tens nanometers) such as titanium dioxide, silica, aluminum salts generally used as antiperspirants, kaolin, talc, clays and their derivatives ... It is also possible to add polymer powders. However, according to a preferred embodiment, the compositions do not include the combination of polymer powders and fibers.

Preservatives such as methyl, ethyl, propyl and butyl esters of phydroxybenzoic acid, sodium benzoate, GERMABEN (brand name) or any chemical agent avoiding bacterial growth or mold and traditionally used cosmetic compositions are generally introduced into these compositions in an amount of 0.01 to 3% by weight. The amount of these products is generally adjusted to prevent any proliferation of bacteria, molds or yeasts in the cosmetic compositions.

As an alternative to these chemical agents, it is sometimes possible to use agents that modify the activity of water and strongly increase the osmotic pressure, such as carbohydrates or salts.

To protect the skin and / or the hair from sun and UV rays, it is possible to add to these formulations sunscreens which are either chemical compounds that strongly absorb UV radiation, such as the compounds authorized in the European Directive No. 76/768 / EEC, its Annexes and subsequent amendments to that Directive or mineral particles, such as zinc oxide, titanium dioxide or cerium oxides in the form of powder or colloidal particles, singly or in combination. These powders may optionally be surface treated to increase the effectiveness of their anti-UV action or to facilitate their incorporation into cosmetic formulations or to inhibit surface photoreactivity.

 To these ingredients is generally added to increase the approval during use of the composition by the consumer, one or more perfumes, coloring agents among which may be mentioned the products described in Annex IV ("List of coloring agents"). allowed for use in cosmetic products ") of European Directive 76/768 / EEC of 27 July 1976, known as the Cosmetic Directive, and / or opacifying agents such as pigments. It is also possible to incorporate in the composition bactericidal or fungicidal agents in order to improve the disinfection of the skin, for example triclosan. These ingredients can be used as fiber supplements. According to particular embodiments of the invention they are replaced by fibers comprising a bioactive agent and / or dyes, pigments. Such fibers have been previously described.

Perfumes, dyes or pigments can be added.

The composition may also contain viscosifying or gelling polymers, such as crosslinked polyacrylates-CARBOPOL marketed by GOODRICH-, cellulose derivatives such as hydroxypropylcellulose, carboxymethylcellulose, guars and their derivatives .... used alone or in combination, or the same compounds, generally in the form of water-soluble polymers modified with hydrophobic groups covalently bound to the polymer backbone as described in WO 92/16187 and / or water to bring the total of the constituents of the formulation to 100%.
