Description

POLYESTER, VISCOUS MIXTURE, PREPARATION PROCESS AND COSMETIC COMPOSITION

[0001] The present application relates to a viscous mixture comprising at least one polyester and at least one bio-sourced hydrocarbon compound.

[0002] The present application also relates to a process for preparing such a mixture.

[0003] It also concerns polyester and its preparation process.

[0004] Furthermore, the invention relates to the polyester compound and the cosmetic composition comprising the mixture according to the invention.

[0005] As part of this request, a number of definitions must be given.

[0006] An "alkane" is a saturated hydrocarbon consisting solely of carbon and hydrogen atoms linked together by simple covalent bonds, the general formula of which is C n H2n+2.

[0007] A "linear alkane" is an alkane in which each carbon atom is linked to a maximum of two carbon atoms.

[0008] A "branched alkane" is an alkane in which some carbon atoms are linked to three or even four carbon atoms.

[0009] We call "C alkane" x » an alkane consisting of x carbon atoms, said alkane being able to be linear or branched. For example, dodecane is a C12 alkane.

[0010] A C>x alkane is an alkane consisting of at least x+1 carbon atoms, and the alkane can be linear or branched. For example, dodecane is a C>10 linear alkane or C12 alkane.

[0011] A "C>x alkane" is an alkane consisting of at least x carbon atoms, said alkane being able to be linear or branched. For example, 2,3,6-trimethylheptane (CAS 4032-93-3) is a C>10 alkane.

[0012] We call "C alkane"x -C y » an alkane consisting of x to y carbon atoms, said alkane being able to be linear or branched. For example, C1-C2 alkanes are methane and ethane.

[0013] An "isoalkane" is a branched alkane containing at least one carbon atom linked to at least three carbon atoms including a methyl group.

[0014] A "polyester" is a polymer whose main chain consists of an alternating sequence of units derived from at least one dicarboxylic acid and units derived from at least one alcohol comprising at least two hydroxyl functions, these units being linked together by ester functions.

[0015] A "hydrocarbon compound" means a compound consisting essentially of carbon and hydrogen atoms.

[0016] The "hydroxyl index" is the quantity of free hydroxyls measured according to the NF ISO 4629 4629-2 method. The hydroxyl index is expressed in mg KOH / g.

[0017] For the purposes of the present invention, the term "viscosity" refers to the kinematic viscosity which is the quotient of the dynamic viscosity by the density or mass of the fluid. Kinematic viscosity is commonly expressed in centistokes (cSt) or mm 2 . s -1 .

[0018] The term "mass percentage" refers to the ratio of the mass of a first compound to the total mass of a mixture of compounds or composition, reduced to a percentage. For example, if 10 grams of a compound y are present in a mixture z having a total mass of 100 grams, then the mass percentage of y in z is 10%.

[0019] The polyesters according to the invention are characterized by their molecular mass, this is measured by the method known as Size Exclusion Chromatography (SEC) and it is expressed in g / mol.

[0020] The polyesters according to the invention are characterized by their colorimetry, this is determined by the APHA-HAZEN method according to standard ASTM D 1209 and it is expressed in APHA.

[0021] A "bio-sourced" compound or organic composition is one in which the organic carbon present in the compound or composition is 100% of plant origin ( 14 C) by radiocarbon analysis according to one of the following standards ASTM D6866, EN 16640 or EN 16785-1.

[0022] The "naturalness index" of an organic composition is called the percentage of organic carbon of plant origin ( 14 C) determined by radiocarbon analysis according to one of the following standards ASTM D6866, EN 16640 or EN 16785-1.

[0023] In cosmetic or dermatological products, fine control of the product's structure or viscosity is necessary in relation to the intended application and represents one of the critical elements regarding the user's appreciation of the product. For example, a lipstick, a foundation or an eyeshadow must not run once applied to the skin, while a hair product such as a gel or serum, for example, must be able to be easily spread by the user on the hair.

[0024] Ingredients for adjusting the structural, thickening and gelling characteristics of a cosmetic product include waxes, mineral fillers based on silica in particular, hydrophobized clays such as bentonites, metallic salts of fatty acids, fatty acid esters and derivatives. of sugars or oligosaccharides functionalized by fatty acids such as dextran palmitate or sucrose esters.

[0025] Available structuring agents have disadvantages. Waxes, for example, can leave the skin feeling too greasy and lead to a dull appearance and a loss of shine.

[0026] Structuring products must therefore allow for fine adjustment of the product's consistency without negatively impacting the feel, durability, color, and shine in particular. There is therefore a need to offer structuring products that "spectate" the other characteristics of the product, or even better, that allow them to be improved. Such products are of great interest because they can reduce the number of ingredients used in a cosmetic composition.

[0027] Polyesters derived from the condensation of naturally occurring fatty carboxylic acids and polyols have been considered in recent years as being able to adjust the consistency of cosmetic products while maintaining or even improving properties such as shine.

[0028] NIPPON FINE CHEMICAL offers oligomers of esters derived from dilinoleic acid dimers and particular dilinoleic diol dimers under the trade names LUSPLAN DD-DA5® and LUSPLAN DD-DA7®. These oligoesters, obtained by polycondensation in a heptane solvent, have a yellowish color and cannot replace a thickening or gelling agent due to their low viscosity. In addition, the hydroxyl number of the commercial product LUSPLAN DD-DA7® is between 50 and 55 mg KOH / g, which is therefore higher than the hydroxyl numbers of the polyesters according to the invention.

[0029] L'OREAL has filed two patent applications, WO2013191302 and WO2018119762, which disclose cosmetic compositions containing polyesters with high hydroxyl numbers, such as PLANDOOL G. These polyesters are obtained by the condensation of acid dimers and alcohol dimers, in the presence of monoalcohols such as behenyl alcohol and / or phytosterol derivatives. The presence of these reagents makes it possible to convert some of the free hydroxyl groups resulting from the condensation reaction.

[0030] The same type of oligomers is disclosed in patent JP2018123117, in the name of the company NIPPON FINE CHEMICAL. These polyesters are obtained by condensation between an acid dimer and a diol dimer under hot conditions and at atmospheric pressure. The products thus obtained are subsequently diluted to 50 w / w% in a mixture of liquid paraffin and ethylhexyl palmitate, in a proportion of 1:1. However, the experimental conditions used in this patent application do not make it possible to obtain final polyesters comparable to those of the present invention because their polymerization rate will be lower and therefore their hydroxyl index will be higher due to a greater number of functional groups that have not reacted, and therefore left free.

[0031] Polyesters derived in particular from fatty acids have also been proposed by the company CRODA in patent applications EP1962790A1 and EP2004137A1. These polyesters are obtained by condensation of 3 reactants: a dicarboxylic acid, a polyol carrying 3 to 8 hydroxyl functions and a C16-C30 monocarboxylic fatty acid.

[0032] The Applicant also proposed polyesters obtained by condensation between dilinoleic acid and 1,4-butanediol, polyesters available under the trade name Viscoplast 14436H. These low-viscosity liquid polyesters were notably combined with a fatty phase in patent application FR2931670A1 from the company L'OREAL.

[0033] NITTO DENKO CORPORATION in application EP2853573 presents the manufacture of polyesters used, after crosslinking with isocyanates, in adhesive compositions to be applied to the skin. These polyesters are obtained by condensation between an acid dimer and an alcohol dimer. These condensations are carried out either at very low pressure and without elimination of water, and preferably in two stages, or at atmospheric pressure but with distillation of the water generated during the reaction. The first stage is carried out at a temperature between 170 and 190 °C under a vacuum between 7 and 13 mbar and the second stage at an even lower pressure, between 2 and 8 mbar, and at a temperature between 215 and 235 °C. Unlike the polyesters according to the invention, it is necessary for them to have free hydroxyl functions to allow them to be crosslinked with isocyanate-type derivatives.

[0034] Due to their biodegradable nature and potential structuring agents, polyesters obtained by condensation of fatty acids and fatty alcohols are of definite interest for the preparation of cosmetic compositions.

[0035] Their use has so far been limited due to their low viscosity, hence the use of additional lipophilic thickening or gelling agents, in particular non-biodegradable synthetic polymers such as polyorganosiloxanes or copolymers of the polystyrene / copoly(ethylene-propylene) or polystyrene / copoly(ethylene-butylene) type.

[0036] The multiplication of ingredients complicates the work of the formulator and requires extremely precise dosage of the latter to obtain properties of interest to the user and also to ensure the stability of these properties over time.

[0037] Surprisingly, it was shown that high viscosity polyesters with a low hydroxyl index could be obtained by a condensation reaction in the presence of at least one bio-sourced hydrocarbon compound.

[0038] The mixture according to the invention comprising at least one polyester and at least one bio-sourced hydrocarbon compound has a viscosity such that it makes it possible to limit, or even eliminate, the use of thickening or gelling agents in cosmetic compositions.

[0039] Furthermore, the process for preparing the mixture according to the invention allows the preparation of cosmetic compositions which can have a naturalness index greater than or equal to 90%, more advantageously greater than or equal to 95%.

[000439] Classically, according to the book Conception des produits cosmétiques : la formulation, by Anne-Marie PENSE-LHERITIER published in 2014 by LAVOISIER, the composition of a lipstick is based on a pair: base or support Pigmentary part [000440] The base contains different types of ingredients selected essentially on their organoleptic properties: volatile solvents to facilitate application and hold; oils to provide slip and ease of application; waxes, to fix the consistency and hardness; fatty substances such as pasty fatty substances or gelling agents to adjust the smoothness and ease of use. [000441] Obtaining a lipstick is done by finding a subtle balance between these different ingredients. [000442] Various additives providing specific properties can be added to these ingredients: polymers, absorbent powders, stabilizing additives (antioxidants, preservatives, etc.), perfume and active ingredients where appropriate. [000443] In one embodiment, the cosmetic compositions for long-lasting lipstick, or lip glosses comprising the mixture according to the invention have excellent stability and remarkable cosmetic qualities such as ease of application, water resistance, good hold, intense and luminous color. [000444] The invention also relates to the use of the mixture according to the invention for the preparation of a cosmetic makeup composition for the eyes. [000445] In one embodiment, the mixture according to the invention is used for the preparation of a cosmetic mascara or eyeliner composition. [000446] Traditionally, according to the book Conception des produits cosmétiques : la formulation, by Anne-Marie PENSE-LHERITIER published in 2014 by LAVOISIER, there are mainly two types of mascara formulations: Continuous water-based mascaras are also called “water-based mascara”. Oil-based mascaras are also called "waterproof mascara" [000447] In one embodiment, the mixture according to the invention is used for the preparation of cosmetic compositions of mascaras with a continuous oil phase. [000448] Continuous oil-phase mascaras are mainly based on the use of wax or continuous oil-phase emulsion. The aim is to form a continuous film on the surface of the eyelash, a film that is perfectly water-resistant. [000449] To do this, the mascara composition comprises in particular a fatty phase and a pigmentary part and this composition may optionally comprise an aqueous phase. [000450] In one embodiment, the mascara composition comprising the mixture according to the invention comprises a mass percentage of less than or equal to 10% of water relative to the total mass of the composition. [000451] In a preferred embodiment, the mascara composition comprising the mixture according to the invention is free of an aqueous phase. [000452] The fatty phase includes in particular volatile solvents, oils, surfactants, waxes, gelling agents, film-forming polymers, and preservatives. [000453] The pigmentary part includes water-soluble dyes, fat-soluble dyes, pigments, pearlescent agents and glitter. [000454] Obtaining a mascara is done by finding a subtle balance between these different ingredients. [000455] Various additives providing specific properties can be added to these ingredients: polymers, absorbent powders, stabilizing additives such as antioxidants, perfume and active ingredients where appropriate. [000456] Concerning eyeliners, their composition is similar to that of the mascaras developed above. [000457] In one embodiment, the cosmetic compositions for the eyes, such as those of mascara or eyeliner, comprising the mixture according to the invention have excellent stability and remarkable cosmetic qualities such as ease of application, water resistance, good hold and a more intense color. [000458] The invention also relates to the use of the mixture according to the invention for the preparation of a cosmetic composition applicable to the skin. [000459] In one embodiment, the mixture according to the invention is particularly used for the preparation of cosmetic compositions such as a primer or makeup base, a blush, an eyeshadow, a foundation or a makeup remover formulation. [000460] Foundation is a formulation intended to unify the skin and lightly color it. It must be applied in a uniform layer but also allow blending, on the face and part of the neck. [000461] Similarly, we understand by base, primer or makeup base a cosmetic composition which makes it possible to fade skin imperfections and prevents makeup from settling into wrinkles and pores throughout the day. This formulation helps perfect skin before applying foundation, blush, etc. [000462] Blush, or commonly called "blush", is a cosmetic formulation intended to mimic or reinforce a "pink cheek" appearance. [000463] Similarly, eye shadow or commonly called "eye-shadow" means cosmetic formulations applicable to the eyelid in order to highlight the eyes by creating color contrasts. [000464] By makeup remover formulation we mean a makeup remover oil but also a biphasic makeup remover formulation which allows the face to be cleaned of makeup while respecting the skin of its user. [000465] As stated above, these make-up removing formulations can be in the form of a make-up removing oil made up of oils and various fatty substances. [000466] They can also be presented in the form of a two-phase formulation comprising an aqueous phase and an oily phase. [000467] Conventionally, the mixture according to the invention is used for the preparation of cosmetic compositions applicable to the skin, in particular foundation and / or base compositions which can be formulated in a fluid or solid form of powder type, loose compact or cast. [000468] These compositions can in particular, independently of one another, be presented in an anhydrous form or in the form of an emulsion. [000469] These emulsions can be presented in different forms, namely in the form of an oil-in-water emulsion, water-in-oil but also under certain conditions in the form of a multiple W / O / W (water / oil / water) or even H / W / O (oil / water / oil) emulsion combining at least one aqueous phase and one fatty phase. [000470] In one embodiment, the mixture according to the invention is used for the preparation of a cosmetic composition applicable to the skin comprising at least one aqueous phase and one fatty phase. [000471] The aqueous phase consists essentially of water. [000472] The fatty phase contains different types of ingredients selected essentially on their organoleptic properties: volatile solvents to facilitate the application and hold of oils to give slip and ease of application to waxes, to fix the consistency and hardness of fatty substances such as pasty fatty substances or gelling agents to adjust the smoothness and ease of use. [000473] Generally, the mixture according to the invention is used for the preparation of a cosmetic composition applicable to the skin comprising a pigmentary part. [000474] Obtaining a satisfactory cosmetic composition applicable to the skin is achieved by seeking a subtle balance between these different ingredients. [000475] Different additives providing specific properties can be added to these ingredients: polymers, absorbent powders, stabilizing additives (antioxidants, preservatives, etc.), perfume and active ingredients where appropriate. [000476] In one embodiment, the cosmetic compositions applicable to the skin such as bases or primers, foundations or powders, comprising the mixture according to the invention have excellent stability and remarkable cosmetic properties such as ease of application, water resistance, good hold, more intense and luminous color. [000477] The invention also relates to the use of the mixture according to the invention for the preparation of a cosmetic composition for the treatment of keratin fibers, in particular hair. [000478] In one embodiment, the mixture according to the invention is used for the preparation of cosmetic compositions for the treatment of keratin fibers in the form of a solution, dispersion, oil / water emulsion, water / oil emulsion, water / oil / water emulsion, powder, talc, sponge, mousse, lacquer and gel.[000479] In one embodiment, the mixture according to the invention is used for the preparation of cosmetic compositions for the treatment of keratin fibers such as hair tonics, hair dyes, hair styling products, shampoos, hair conditioners, conditioners, conditioning shampoos, hair treatment products, hair sprays, hair masks, hair care products, hair treatment products, permanent wave fixing solutions, hair shaping products, shampoos for colored hair, hair fixatives, hair holding products, hair styling preparations, leave-in hair products, curling iron lotions, fixing mousses, hair gels, hair waxes or combinations thereof. [000480] In one embodiment, the cosmetic compositions for the treatment of keratin fibers, in particular hair, comprising the mixture according to the invention have excellent stability and remarkable cosmetic properties such as ease of application, good hold, luminous color and intense shine. [000481] The following examples are given to illustrate the invention. [000482] Method for determining viscosity [000483] The viscosity is determined using an automatic Brookfield type viscometer. [000484] The type of mobile and the speed of the mobile are adapted to the measurement range. [000485] The result of the measurement is the dynamic viscosity expressed in cP or mPa.s. [000486] This value divided by the density of the product makes it possible to obtain the kinematic viscosity expressed in cSt or mm 2 . s -1 . [000487] Method for determining the acid index [000488] The quantity of free acids is determined using the NF EN ISO 660 method. [000489] Method for determining the hydroxyl number [000490] The quantity of free hydroxyls is determined using the NF ISO 4629 4629-2 method. [000491] Method for determining density [000492] Density is measured using a DENSITO device from Mettler Toledo. It is expressed in g. cm -3 . [000493] Method for measuring the refractive index [000494] The refractive index is measured using an automatic device of the Model RFM330-M type, Belligham and Stanley Ltd.
