Description

COMPOSITION Comprising an aminosilicon, a cationic surfactant and a cationic associative polymer [001] The present invention relates to a composition for treating keratin fibers, in particular human keratin fibers such as hair, comprising (i) one or more aminosilicones, (ii) one or more cationic surfactants and (iii) one or more cationic associative polymers.

[002] The invention also relates to a process for treating keratin fibers, in particular human keratin fibers such as hair, and to a use for hair care using said composition.

[003] Many people are dissatisfied with the appearance of their hair, and have difficulty styling it. Hair is usually damaged and weakened by the action of external atmospheric agents such as light and bad weather, and also by mechanical or chemical treatments, such as brushing, combing, coloring, discoloration, permanent waving and / or relaxation.

[004] Hair is thus damaged by these various factors and can over time become dry, rough or dull, especially in fragile areas, and more particularly at the ends, leading to the appearance of split ends.

[005] Thus, to overcome these drawbacks, it is common practice to use hair care products using compositions that condition the hair properly, giving it satisfactory cosmetic properties, especially in terms of softness, shine, softness, suppleness, lightness, a natural feel and good detangling properties, while being able to minimize split ends.

[006] These hair care compositions can be, for example, conditioning shampoos, hair conditioners, masks or serums, and can be in the form of gels, hair lotions or care creams that are more or less thick.

[007] These compositions can comprise silicones, which are used as conditioning agents, in order to provide the hair with a level of

Petition 870190063619, of 07/08/2019, p. 8/51

2/36 satisfactory care, especially in terms of softness, smoothness and suppleness, and to manage the reduction of split ends.

[008] However, silicones often have the disadvantage of making hair very runny and heavy, which leads to the phenomenon commonly known as the build-up effect. In other words, silicones are deposited in a large amount of matter in the hair, which has the consequence that the hair becomes dull and limits the use of silicones in hair conditioning.

[009] These hair care products can also have the disadvantage of giving the hair an unnatural aspect.

[010] Therefore, there is a real need to develop cosmetic compositions, for example hair conditioners, that do not have the combination of disadvantages described above, that is, that are able to positively treat and nourish hair, especially sensitized hair, namely giving it softness, smoothness and suppleness, while making it lighter and more natural.

[011] The Applicant has surprisingly discovered that it is possible to formulate compositions for the cosmetic treatment of keratin fibers, which have the desired properties, combining in these compositions one or more aminosilicones, one or more cationic surfactants and one or more cationic associative polymers.

[012] In particular, it has been found that such a combination allows selectively depositing an appropriate amount of aminosilicones on hair, especially on sensitized hair, to improve the cosmetic properties that are conferred on it, while making it lighter and more natural. In other words, the treated hair is less runny and heavy, while the cosmetic properties are improved.

[013] More particularly, silicon deposits lead to softer, smoother and more malleable hair and the number of split ends is also reduced.

3/36 [014] The present invention relates in particular to a composition comprising:

(i) one or more aminosilicones, (ii) one or more cationic surfactants other than (i), and (iii) one or more cationic associative polymers.

[015] The composition of the present invention is able to improve the cosmetic properties of keratin fibers, in particular human keratin fibers such as hair, especially in terms of softness, smoothness and malleability, while providing hair with an appearance and a more natural feel.

[016] The present invention also relates to a process for treating hair, comprising applying to said hair the composition according to the invention.

[017] The invention also relates to the use of the composition according to the invention as a hair conditioner, preferably used after applying a shampoo.

[018] Other subjects and characteristics, aspects and advantages of the invention will emerge even more clearly from reading the description and examples that follow.

Cationic associative polymer

Petition 870190063619, of 07/08/2019, p. 24/51

18/36 [074] Cationic associative polymers are water-soluble or water-dispersible cationic polymers capable, in an aqueous medium, of reversibly combining with each other or with other molecules.

[075] In one embodiment, the associative polymer used in the invention is an amphiphilic polymer, which means that it is a polymer that comprises at least one hydrophilic unit that makes the polymer soluble in water and at least one hydrophobic region, comprising at least one grease chain, through which the polymer interacts and is associated with another associative polymer or with other molecules.

[076] Thus, the cationic associative polymer used in the present invention is preferably a cationic amphiphilic polymer comprising at least one hydrophilic group and at least one grease chain.

[077] According to the present invention, a grease chain has at least 8 carbon atoms, preferably 8 to 30 carbon atoms, more preferably 10 to 30 carbon atoms and especially 12 to 22 carbon atoms.

[078] According to the present invention, the cationic associative polymer has at least one repetitive unit other than an oxyalkylene group. Thus, associative polymers are different from products that result merely from the condensation of an alkylene oxide with an alcohol, an ester or an amide.

[079] Cationic amphiphilic associative polymers can be chosen from:

- (1) cationic associative amphiphilic polyurethanes, which can be water-soluble or water-dispersible, whose family was described by the Applicant in French patent application No. 00/09609.

[080] Cationic amphiphilic associative polyurethanes can be represented by the general formula (XIII) below:

R-X- (P) n- [L- (Y) m] r-L '- (P') p-X'-R '(XIII) where:

Petition 870190063619, of 07/08/2019, p. 25/51

19/36

R and R ', which can be identical or different, represent a hydrophobic group or a hydrogen atom;

X and X, which can be identical or different, represent a group comprising an amine function optionally having a hydrophobic group, or, alternatively, an L group;

L, L 'and L, which can be identical or different, represent a group derived from a diisocyanate;

P and P ', which may be identical or different, represent a group comprising an amine function optionally having a hydrophobic group;

Y represents a hydrophilic group;

r is an integer between 1 and 100, preferably between 1 and 50, and in particular between 1 and 25;

n, m and p vary, each independently from the others, between 0 and 1000;

the molecule containing at least one protonated or quaternized amine function and at least one hydrophobic group.

[081] In a preferred embodiment of these polyurethanes, the only hydrophobic groups are the R and R 'groups at the ends of the chain.

[082] A preferred family of cationic associative polyurethanes is that corresponding to the formula (XIII) described above and in which:

R and R 'both independently represent a hydrophobic group,

X and X each represent a group L, n and p vary between 1 and 1000, and

Petition 870190063619, of 07/08/2019, p. 26/51

20/36 [084] The fact that η and ρ are 0 means that these polymers do not comprise units derived from a monomer that contains an amine function incorporated in the polymer during polycondensation. The protonated amine functions of these polyurethanes result from the hydrolysis of excess isocyanate functions at the end of the chain, followed by alkylation of the primary amine functions formed by alkylating agents containing a hydrophobic group, that is, compounds of the RQ or R'Q type, in that Re R 'are as defined above and Q denotes an leaving group such as a halide, a sulfate, etc.

[085] Yet another preferred family of cationic associative polyurethanes is that corresponding to formula (I) above in which:

Re R 'both independently represent a hydrophobic group,

X and X 'both independently represent a group comprising a quaternary amine, n and p are zero, and

L, L ', Y and m have the meaning given above.

[086] The average molecular weight in number of cationic associative polyurethanes is preferably between 400 and 500 000, in particular between 1000 and 400 000 and ideally between 1000 and 300 000.

[087] The term hydrophobic group means a radical or polymer containing a hydrocarbon based chain, saturated or unsaturated, linear or branched, which may contain one or more hetero atoms such as Ρ, O, N or S, or a radical containing a perfluorinated or silicone chain. When the hydrophobic group denotes a hydrocarbon-based radical, it comprises at least 10 carbon atoms, preferably 10 to 30 carbon atoms, in particular 12 to 30 carbon atoms and more preferably 18 to 30 carbon atoms.

[088] Preferably, the hydrocarbon-based group is derived from a monofunctional compound.

[089] For example, the hydrophobic group can be derived from a fatty alcohol such as stearyl alcohol, dodecyl alcohol or decyl alcohol. Can

[090] When X and / or X 'denotes (m) a group comprising a tertiary or quaternary amine, X and / or X' may represent one of the following formulas:

—NR, - · —N — R-> - —R _: - or— i - i + laughs

Ri Rj A NNt n / 'o ^R 1 IR [ ^K l ^K 1R, r ₃ —R, -N— —R ₂ -N— - R ₂ - ^Or t JL A * IM + A “

—Z-C-NH-R4-NH-C-Z— II II where:

Z represents -O-, -S- or -NH-; and

Petition 870190063619, of 07/08/2019, p. 28/51

22/36

R4 represents a linear or branched alkylene radical containing 1 to 20 carbon atoms, optionally comprising a saturated or unsaturated ring, or an arylene radical, with one or more of the carbon atoms possibly substituted with a heteroatom chosen from N, S, O and P.

[092] The groups P and P 'comprising an amine function can represent at least one of the following formulas:

Ko r —R ₅ -NR ₇ - Or * 6 - R ₅ -NR ₇ - R $ A ^ 6% Λβ N | or ~~ R _? —CH ~ R ₇ ~~ or - r _? -ch-R ₇ - R _í -NR _$ A r ₈ Λ N 1 or - R ₅ -CH-R ₇ - - R - CH-R ₇ - Or p γιο R ^ -N-Rg A

on what:

Rs and R? have the same meanings as R2 defined above;

Re, Rs and R9 have the same meanings as R1 and R3 defined above;

R10 represents a linear or branched alkylene group, optionally unsaturated, possibly containing one or more hetero atoms chosen from N, O, S and P; and

A 'is a physiologically acceptable counterion.

[093] Regarding the meaning of Y, the term hydrophilic group means a water-soluble polymeric or non-polymeric group.

[094] As an example, when it is not a polymer, reference can be made to ethylene glycol, diethylene glycol and propylene glycol.

Petition 870190063619, of 07/08/2019, p. 29/51

23/36 [095] In the case of a hydrophilic polymer, according to a preferred embodiment, reference can be made, for example, to polyethers, sulfonated polyesters, sulfonated polishes or a mixture of these polymers. The hydrophilic compound is preferably a polyether and especially a poly (ethylene oxide) or poly (propylene oxide).

[096] The cationic associative polyurethanes of formula (XIII) that can be used according to the invention are formed from diisocyanates and various compounds that have functions containing a labile hydrogen. The functions containing a labile hydrogen can be functions of alcohol, primary or secondary amine or thiol, producing, after reaction with diisocyanate, polyurethanes, polyureas and polythioureas functions, respectively. The term polyurethanes that can be used in accordance with the present invention encompasses these three types of polymers, namely polyurethanes themselves, polyureas and polythioureas, and also copolymers thereof.

[097] A first type of compound involved in the preparation of the polyurethane of formula (XIII) is a compound comprising at least one unit that contains an amine function. This compound can be multifunctional, but the compound is preferably bifunctional, that is, according to a preferred embodiment, this compound comprises two labile hydrogen atoms derived, for example, from hydroxyl, primary amine, secondary amine or thiol functions. A mixture of multifunctional and bifunctional compounds in which the percentage of multifunctional compounds is low can also be used.

[098] As mentioned above, this compound can comprise more than one unit containing an amine function. In this case, it is a polymer that has a repeat of the unit containing an amine function.

[099] Compounds of this type can be represented by one of the following formulas:

HZ- (P) n-ZH or

HZ- (P ') p-ZH

Petition 870190063619, of 07/08/2019, p. 30/51

24/36 where Z, P, P ', n and p are as defined above.

[0100] Examples of compounds containing an amine function that may be mentioned include N-methyldiethanolamine, N-tert-butyldiethanolamine and Nsulfoethyldiethanolamine.

[0101] The second compound included in the preparation of the polyurethane of formula (XIII) is a diisocyanate corresponding to the formula:

O = C = NR ₄ -N = C = O where R4 is as defined above.

[0102] For example, methylenediphenyl diisocyanate, methylene cyclohexane diisocyanate, isophorone diisocyanate, tolylene diisocyanate, naphthalene diisocyanate, butane diisocyanate and hexane diisocyanate can be mentioned.

[0103] A third compound involved in the preparation of the polyurethane of formula (XIII) is a hydrophobic compound intended to form the terminal hydrophobic groups of the polymer of formula (XIII).

[0104] This compound is formed from a hydrophobic group and a function containing a labile hydrogen, for example a hydroxyl function, primary or secondary amine, or thiol.

[0105] As an example, this compound can be a fatty alcohol, such as, in particular, stearyl alcohol, dodecyl alcohol or decyl alcohol. When this compound comprises a polymeric chain, it can be, for example, a-hydroxylated hydrogenated polybutadiene.

[0106] The hydrophobic group of the polyurethane of formula (I) can also result from the tertiary amine quaternization reaction of the compound comprising at least one tertiary amine unit. Thus, the hydrophobic group is introduced through the quaternizing agent. This quaternizing agent is a compound of the type RQ or R'Q, in which R and R 'are as defined above and Q designates a leaving group such as a halide, a sulfate, etc.

[0107] The cationic associative polyurethane can also comprise a hydrophilic block. This block is provided by a fourth type of compound involved in the

Petition 870190063619, of 07/08/2019, p. 31/51

25/36 preparation of the polymer. This compound can be multifunctional. It is preferably bifunctional. It is also possible to have a mixture where the percentage of multifunctional compound is low.

[0108] Functions containing a labile hydrogen are alcohol, primary or secondary amine, or thiol functions. This compound can be a polymer terminated at the ends of the chain with one of these functions containing a labile hydrogen.

[0109] As an example, when it is not a polymer, reference can be made to ethylene glycol, diethylene glycol and propylene glycol.

[0110] When dealing with a hydrophilic polymer, reference can be made, for example, to polyethers, sulfonated polyesters and sulfonated polyamides, or a mixture of these polymers. The hydrophilic compound is preferably a polyether and especially a poly (ethylene oxide) or poly (propylene oxide).

[0111] The hydrophilic group designated Y in formula (I) is optional. Specifically, units containing a quaternary or protonated amine function may be sufficient to provide the required water solubility or dispersibility for this type of polymer in an aqueous solution.

[0112] Although the presence of a hydrophilic Y group is optional, cationic associative polyurethanes comprising such a group are nevertheless preferred.
