Description

<Desc / Clms Page number 1>

The present invention relates to the use of a mascara composition comprising a vinyl lactam polymer for curling the eyelashes. The invention also relates to a transparent or translucent mascara composition comprising such a polymer. The use and the composition according to the invention are more particularly intended for human eyelashes or else for false eyelashes. The term “mascara” is intended to mean an eyelash makeup composition, a makeup base, a product to be applied to makeup, also called a top coat, or even a cosmetic treatment product for eyelashes.

Mascaras generally contain a film-forming polymer for the purpose of depositing a film covering the eyelashes. Such mascaras are notably described in documents WO 91/1273, EP-A-530084 and WO 95/15741.

Users are looking for mascars that confer significant curling of the eyelashes. However, not all film-forming polymers make it possible to obtain satisfactory curling of the eyelashes. In addition, certain film-forming polymers such as, for example, hydroxyethylcellulose or hydroxypropylchitosan form on the eyelashes after drying a whitish film leading to unsightly makeup.

Such polymers are therefore not suitable for transparent mascaras.

There is therefore a need to have a mascara having good curling properties and in particular making it possible to form a transparent make-up of the eyelashes.

The present invention therefore aims to provide a mascara composition comprising a film-forming polymer conferring good curling properties of the eyelashes, in particular making it possible to form a transparent film deposited on the eyelashes.

The Applicant has found that such a mascara can be obtained using a vinyl lactam polymer. The use of this polymer makes it possible to obtain a mascara curling the eyelashes. In addition, the film-forming polymer forms a transparent film allowing the eyelashes to be shaped without modifying their apparent color: it is therefore possible to use this polymer in a transparent composition to curl the eyelashes, thus making it possible to obtain a transparent or translucent composition. original and different from classic colorful mascaras. In addition, such a transparent or translucent composition can be applied either to a colored mascara already deposited on the eyelashes and thus give them a greater curling without modifying the color of the mascara already deposited, or directly on the eyelashes before the application of a colored mascara, to obtain the desired curling of the eyelashes.

More specifically, the subject of the invention is the use of a mascara composition comprising, in a cosmetically acceptable medium, a polymer

 vinyl lactam film-forming agent, ethylenically unsaturated carboxylic acid, and possibly hydrophobic monomer, for curling the eyelashes.

The subject of the invention is also the use of a transparent or translucent mascara composition, comprising, in a cosmetically acceptable medium, a film-forming polymer of vinyl lactam, of ethylenically unsaturated carboxylic acid, and optionally of hydrophobic monomer, for The object of the invention is also the use of a film-forming polymer of vinyl lactam, of ethylenically unsaturated carboxylic acid, and optionally of hydrophobic monomer, in a mascara composition comprising a cosmetically acceptable medium, for curling the lashes.

Another subject of the invention is a transparent or translucent mascara composition comprising, in a cosmetically acceptable medium, a film-forming polymer, characterized in that the film-forming polymer is a polymer of vinyl lactam, of ethylenically unsaturated carboxylic acid, and optionally of hydrophobic monomer.

The invention also relates to a mascara product comprising a reservoir containing a mascara composition as defined above, and provided with a system for applying the composition to the eyelashes.

The subject of the invention is also a method of coating the eyelashes comprising the application to the eyelashes of a mascara composition as defined above. The eyelash coating process is in particular a non-therapeutic cosmetic make-up or treatment process for eyelashes.

The term “cosmetically acceptable medium” means a medium compatible with keratin materials.

The film-forming polymer present in the mascara for the use according to the invention is a polymer resulting from the polymerization of vinyl lactam, of ethylenically unsaturated carboxylic acid, and optionally of hydrophobic monomer.

The vinyl lactam can be vinyl pyrrolidone or vinyl caprolactam. Vinyl pyrrolidone is preferably used.

The ethylenically unsaturated carboxylic acid can be chosen from (meth) acrylic acid, itaconic acid, maleic acid and crotonic acid. Preferably acrylic acid is used.

 Advantageously, the film-forming polymer essentially consists of a terpolymer of vinyl lactam, of ethylenically unsaturated carboxylic acid and of hydrophobic monomer. Such a terpolymer is especially sold under the name "ACRYLIDONE #" by the company ISP.

The film-forming polymer is known from the state of the art and is described in particular in patent US-A-5015708.

A particularly preferred polymer is the vinyl pyrrolidone / acrylic acid / lauryl methacrylate terpolymer, such a polymer is sold under the name "ACRYLIDONE LM #" by the company ISP (in respective weight percent 68/23/9).

Such a wax makes it possible to maintain good curling of the eyelashes. The needle penetration of waxes is determined according to French standard NF T 60-123 or American standard ASTM D 1321, at a temperature of 25 C. According to these standards, needle penetration is the measure of depth , expressed in tenths of a millimeter, into which a standard needle, weighing 2.5 g placed in a mobile assembly weighing 97.5 g and placed on the test wax, for 5 seconds, enters the wax.

The composition may also contain at least one auxiliary film-forming polymer different from the film-forming vinyl lactam polymer defined above, in a content which can range from 0% to 15% by weight (in particular 0.1% to 15% by weight), relative to the total weight of the composition, and preferably from 0.1% to 10% by weight.

According to a particular embodiment of the invention, the composition is transparent or translucent. In particular, the transparent or translucent composition may be free of wax, while giving the eyelashes good curling properties.

The transparent or translucent composition applied to the eyelashes forms, after drying, a transparent film covering the eyelashes. This gives a transparent and curling mascara. This mascara therefore makes it possible to curl the eyelashes without modifying their apparent color: it is perfectly suitable for improving the curling of eyelashes already made up with a mascara having properties that are slightly or not curling, without modifying the color of the makeup already deposited on the eyelashes. It is also possible to apply this mascara directly to the eyelashes and then apply a colored mascara to the deposited transparent film. The transparent composition is therefore entirely suitable for the colorless shaping of eyelashes.

By "transparent composition" is meant according to the invention, a composition allowing light to pass through without causing deflection by refraction or reflection.

The transparency of the composition can be measured using a Turbidimeter.

The Model 2100P 'portable turbidimeter from HACH can for example be used for measurements of the transparency ranges of the composition. The composition is considered to be transparent when the measured turbidity value is between 0 and 250 NTU and it is considered to be translucent for a turbidity value ranging from 250 to 1000 NTU.

By “wax-free composition” is meant a composition comprising less than 0.4% by weight of wax, relative to the total weight of the composition, preferably less than 0.2% by weight, or even having a content of zero wax.

The transparent composition may contain other additives such as those mentioned in the present application, provided that the transparency property of the composition is retained.
