Description

The subject of the invention is a cosmetic composition intended to be

  applied to keratin fibers, in particular hair and comprising at least one cellulose ester of the phthalate, acetophthalate or acetotrimellitate type in a cosmetically acceptable medium. It also relates to a process for treating keratin fibers using this composition as well as the use of these cellulose esters for the formulation of styling products such as hairsprays, sprays or foams, on the one hand as an agent for coating keratin fibers and in particular as an agent for maintaining and / or fixing the hair, and / or on the other hand as an agent improving the

  holding the hairstyle in humidity.

  For the purposes of the present invention, the term "keratin fibers" means

  hair, eyelashes and eyebrows, and more particularly the hair.

  Film-forming polymers soluble in aqueous and hydroalcoholic media such as polyvinylpyrrolidone, vinylpyrrolidone / vinyl acetate copolymers, vinyl acetate / crotonic acid copolymers, anionic or amphoteric acrylic resins and derivatives of

  cellulose are commonly used in styling products.

  The most common hair products for fixing hair on the cosmetic market are aerosol or pump spray compositions such as hairsprays, sprays or foams, essentially consisting of a solution, most often alcoholic or hydroalcoholic and of a film-forming polymer soluble in water and in alcohol,

  such as those mentioned above, mixed with various cosmetic adjuvants.

  In general, the holding of the hairstyle is influenced by the climate and the surrounding atmospheric conditions. Thus, curly hair fixed with a fixing hair product tends to relax in a humid environment. The curls come undone and, against the user's will, the hairstyle can more or less completely lose the shape that was given to it initially. For a number of years, a particular interest has manifested itself in hair products capable of lastingly fixing the hair whatever the climatic conditions. It is, in particular, to find fixing products that can be used in humid conditions

relative high.

  Furthermore, it is sought to reduce the concentrations of volatile compounds at atmospheric pressure called VOCs (Volatile Organic Compound) present

  in the compositions to be sprayed in the form of an aerosol or a pump bottle.

  Indeed, the use of alcohol, alone or in mixture with a small amount of water as well as the use of propellants can have certain drawbacks such as increased flammability or nuisance vis-à-vis of the environment. VOCs are mainly propellants such as

  hydrocarbons or dimethyl ether (DME) and solvents such as ethanol.

  We are therefore looking for film-forming polymers compatible with aqueous or hydroalcoholic media, so as to reduce the content of compounds

volatile organic rejected.

  Finally, many compositions for maintaining and / or shaping the hair of the prior art contain in their formulation styling polymers leading to difficult disentangling. In addition, hair treated with these same fixing polymers is generally coarse, has an unnatural feel and provides a powdering effect after combing giving a

  unpleasant and unattractive appearance to the hair.

  Cosmetic compositions are therefore sought for maintaining and / or fixing the hairstyle also providing good disentangling properties,

  softness and giving a beautiful appearance to the user's hair.

  The objective of the invention is to find film-forming polymers for producing cosmetic compositions intended to be applied to keratin fibers, in particular the hair, which make it possible to remedy the

  disadvantages listed above.

  However, surprisingly and unexpectedly, the Applicant has discovered that certain cellulose esters make it possible to remedy the problems

techniques mentioned above.

  In fact, the Applicant has discovered a new family of film-forming polymers making it possible to produce styling products having good fixing properties and good cosmetic properties such as softness,

  the disentangling and the absence of dusting.

  In addition, these particular cellulose esters unexpectedly make it possible to improve the humidity resistance of the hairstyle obtained with compositions.

  fixing and / or holding based on conventional film-forming polymers.

  On the other hand, these same cellulose esters are perfectly compatible in formulations packaged in an aerosol or in a pump bottle, and are more particularly suitable for compositions with content of compounds.

reduced volatile organic.

  The invention therefore provides a cosmetic composition intended to be applied to keratin fibers and comprising, in a cosmetically acceptable medium, at least one cellulose ester whose basic repeating unit has the general formula (I) RO

OR (I)

  in which the groups R, which are identical or different, represent a substituent chosen from the group comprising -H; alkyls and hydroxyalkyls; C = O C = O -C-alkyl denoting a saturated linear or branched radical having 1 H 6 carbon atoms;

  preparation of hair compositions.

  For the purposes of the present invention, the term "auxiliary agent" means an agent which is the accessory of film-forming polymers for the accomplishment of the effects

  wanted to maintain and / or fix the hairstyle.

  Yet another object of the present invention relates to a method of

  cosmetic hair treatment using these cellulose esters.

  According to a preferred embodiment of the compositions according to the invention, the group R is chosen from the group comprising -H, 1,111 III

  In general, the compositions according to the invention are used for hair applications, and more particularly, they are intended for maintaining and / or fixing the hair. Preferably, they are in the form of gels, lotions, mousses, hairsprays or styling sprays. According to a particularly preferred embodiment of the present invention, the cosmetic compositions in accordance with the invention further comprise

  at least one other film-forming polymer.

hydroxypropyl and hydroxybutyl.

  These guar gums are well known in the state of the art and can for example be prepared by reacting oxides of corresponding alkenes, such as for example propylene oxides, with guar gum so as to

  obtain a guar gum modified with hydroxypropyl groups.

  Such nonionic guar gums optionally modified with hydroxyalkyl groups are for example sold under the trade names JAGUAR HP8, JAGUAR HP60 and JAGUAR HP120, JAGUAR DC 293 and JAGUAR HP 105 by the company MEYHALL, or under the name

  GALACTASOL 4H4FD2 by the company AQUALON.

  The alkyl radicals of nonionic polymers have from 1 to 6 atoms of

carbon unless otherwise stated.

  According to the invention, it is also possible to use film-forming polymers of the grafted silicone type comprising a polysiloxane portion and a portion consisting of a non-silicone organic chain, one of the two portions constituting the

  main chain of the polymer, the other being grafted onto said main chain.

  These polymers are for example described in patent applications EP-A-

  0 412 704, EP-A-0 412 707, EP-A-0 640 105 and WO 95/00578, EP-A-0582 152

CH3 CH 3 3CH3 C

  v with v being a number ranging from 5 to 700; the percentages by weight being

  calculated relative to the total weight of the monomers.

  Other examples of grafted silicone polymers are in particular polydimethylsiloxanes (PDMS) onto which are grafted, via a thiopropylene-type connecting link, mixed polymer units of the poly (meth) acrylic acid type and of the poly type. (meth) acrylate and polydimethylsiloxanes (PDMS) onto which are grafted, by means of a thiopropylene-type connecting link, units

  polymers of the isobutyl poly (meth) acrylate type.

  Polyurethanes can also be used as film-forming polymers.

  The film-forming polymer (s) are, for example, present in concentrations of between 0.01% and 15% by weight, and preferably in concentrations of between 0.1% and 10% by weight relative to

the total weight of the composition.

  The cellulose ester (s) may be present in concentrations of between 0.1% and 15% by weight, and preferably in

  concentrations between 0.5% and 10% by weight.

  The cosmetically acceptable medium preferably consists of water or a mixture of water and cosmetically acceptable solvents such as monoalcohols, polyalcohols, glycol ethers or fatty acid esters, which can be used alone or mixed. These solvents are

preferably C1-C4 alcohols.

  Among these alcohols, mention may be made of ethanol, isopropanol, polyalcohols such as diethylene glycol, glycol ethers, such as monoalkyl ethers of glycol, of diethylene glycol, of propylene glycol or of dipropylene glycol. Ethanol is

* particularly preferred.

  The composition of the invention may also contain at least one additive chosen from thickeners, fatty acid esters, fatty acid and glycerol esters, volatile or non-volatile silicones, modified or not, soluble or insoluble in composition, surfactants, perfumes, preservatives, sunscreens, proteins, vitamins, polymers, vegetable, animal, mineral or synthetic oils and any other additive conventionally used in cosmetic compositions intended to be

  applied to keratin fibers.

  These additives are optionally present in the composition according to the invention in proportions which can advantageously range from 0.001 to 20% by weight relative to the total weight of the composition. The precise quantity of each additive depends on its nature and is easily determined by

The skilled person.

  Of course, those skilled in the art will take care to choose the optional compound (s) to be added to the composition according to the invention in such a way that the advantageous properties intrinsically attached to the composition according to the invention are not, or substantially not, altered by the proposed addition. Thus, the keratin fibers treated with the compositions according to the invention have a pleasant feel and appearance and the film-forming power of the composition is

improved in high humidity.

  These compositions can be packaged in various forms, in particular in pump dispensers or in aerosol containers, in order to ensure application of the composition in vaporized form or in the form of foam. Such forms of packaging are indicated, for example, when it is desired to obtain a spray, a lacquer or a foam for

  fixing or treating hair.

  When the composition according to the invention is packaged in the form of an aerosol in order to obtain a lacquer or a foam, it comprises at least one agent

  propellant which can be chosen from volatile hydrocarbons such as n-

  butane, propane, isobutane, pentane, a chlorinated and / or fluorinated hydrocarbon and their mixtures. Carbon dioxide, nitrous oxide, dimethyl ether (DME), nitrogen, air can also be used as a propellant.

tablet and mixtures thereof.

  Advantageously, the propellant is present at a concentration between 5 and 90% by weight relative to the total weight of the composition in the aerosol device and, more particularly, at a concentration between

1 0 and 60%.

  The subject of the invention is also a method of cosmetic treatment of keratin fibers such as the hair, which consists in applying a

  composition as defined above.

  The preparation of the compositions according to the invention is carried out according to methods well known from the state of the art. In particular, the ingredients are mixed and then packaged in an appropriate container according to the intended use. The composition according to the invention is advantageously a product

  capillary for maintaining and / or shaping the hair.
