Description

[0001] COMPOSITION COMPRISING A FATTY AMINE CATIONIC SURFACTANT AND THREE PARTICULAR ALCOHOLS

[0002] The present invention relates to the field of treating keratin fibres, notably the hair, and more particularly to conditioning / caring for the hair.

[0003] The invention relates to a composition comprising at least one fatty amine cationic surfactant, at least one fatty alcohol, at least one polyol and at least one monoalcohol, the polyol and the monoalcohol being present in a particular weight ratio.

[0004] The invention also relates to a process for treating keratin fibres, in particular the hair, which involves at least one step of applying the composition according to the invention to said fibres.

[0005] The invention also relates to a process for treating keratin fibres, in particular the hair, which involves the steps of applying a dye composition and the composition according to the invention to said fibres.

[0006] Hair is generally damaged and embrittled by the action of external atmospheric agents such as light and bad weather, and also by mechanical or chemical treatments, such as brushing, combing, dyeing, bleaching, permanent-waving and / or relaxing, or even repeated washing.

[0007] Hair is thus damaged by these various factors and may over time become dry, coarse, brittle or dull, notably in fragile areas, and more particularly at the ends.

[0008] To overcome these drawbacks, it is common practice to resort to haircare treatments using compositions that condition the hair, giving it satisfactory cosmetic properties, notably in terms of smoothness, sheen, softness, suppleness, lightness, a natural feel and good disentangling properties. These haircare compositions intended to be applied regularly to the hair may be, for example, hair conditioners, masks or sera, and may be in the form of gels, hair lotions or care creams that are more or less thick.

[0009] The products present on the market may have a thick texture and may thus be difficult to take up, to apply and to spread over the entire head of hair.

[0010] In addition, users are increasingly in search of products mainly comprising ingredients of natural origin.

[0011] The object of the present invention is to propose cosmetic compositions, notably hair compositions, which are advantageously in a stable, homogeneous, transparent, slightly gelled (which means slightly thickened) liquid form, allowing the formation of a lamellar phase on contact with water. These compositions areparticularly useful in the field of hair care and / or conditioning; notably rinse-out care preferentially for fine hair and / or sensitized hair. In particular, the slightly gelled texture transforms into a creamy texture upon application to wet hair.

[0012] In order to meet users’ needs, the present invention proposes a stable, homogeneous, transparent composition which provides very good cosmetic performance properties, with an improvement in disentangling, in smooth feel, suppleness, sheen and manageability, along with lightness. The present invention also affords improved working properties, notably a texture which facilitates the application thereof, uniform distribution and also improved, notably faster, rinsing. More particularly, the slightly gelled texture of the compositions according to the invention makes them easier to handle and affords greater precision at the time of application to the area to be treated, when compared with more liquid compositions that flow too quickly. Thus, these slightly gelled compositions enable the use of less product while ensuring good disentangling properties and having very good cosmetic properties, notably in terms of a smooth feel, suppleness, sheen, manageability and lightness.

[0013] These aims are achieved with the present invention, one subject of which is notably a composition, preferably a cosmetic composition, comprising:

[0014] a) at least one fatty amine cationic surfactant,

[0015] b) at least one fatty alcohol comprising from 7 to 40 carbon atoms,

[0016] c) at least one C2-C6 polyol, and

[0017] d) at least one monoalcohol comprising from 1 to 6 carbon atoms,

[0018] and wherein:

[0019] - the weight ratio of the total content of monoalcohol(s) d) to the total content of polyol(s) c) is greater than or equal to 2, and

[0020] - the total content of C2-C6 polyol(s) c) and of Ci-Ce monoalcohol(s) d) ranges from 32% to 80% by weight, relative to the total weight of the composition.

[0021] It has been found that the compositions according to the invention afford better conditioning properties, and the hair thus treated is shiny, has a smooth feel, is supple, easy to disentangle and more manageable, while also being light.

[0022] The compositions according to the invention also have good working qualities in the form of a gelled texture. The compositions according to the invention are notably stable, homogeneous and transparent. In addition, they are easy to apply and to spread on keratin fibres.The invention also relates to a process for treating keratin fibres, in particular human keratin fibres such as the hair, comprising at least one step of applying a composition according to the invention to the keratin fibres.

[0023] A subject of the invention is also a process for dyeing keratin fibres, in particular human keratin fibres such as the hair, comprising at least the following steps: (i) a step of applying a composition (C) comprising at least one dye to keratin fibres, and

[0024] (ii) a step of applying a composition according to the invention, different from the dye composition (C), to the keratin fibres.

[0134] Preferably, the composition according to the invention comprises at least one nonionic polysaccharide.

[0135] More preferentially, the nonionic polysaccharide(s) are chosen from non-associative nonionic polysaccharides, associative nonionic polysaccharides, and mixtures thereof.

[0136] Non-associative nonionic polysaccharides

[0137] Non-associative nonionic polysaccharides that may notably be mentioned include native gums such as:

[0138] a) tree or shrub exudates;

[0139] b) gums derived from algae, including:

[0140] - agar (polymer derived from galactose and anhydrogalactose);

[0141] c) gums derived from seeds or tubers, including:

[0142] - guar gum (polymer of mannose and galactose);

[0143] - locust bean gum (polymer of mannose and galactose);

[0149] e) plant extracts, including:

[0150] - cellulose (glucose polymer);

[0151] - starch (glucose polymer) and

[0152] - inulin.

[0153] These non-associative nonionic polysaccharides may be physically or chemically modified. A physical treatment that may notably be mentioned is the temperature.

[0154] Chemical treatments that may be mentioned include esterification, etherification, amidation or oxidation reactions. These treatments can also afford nonionic polymers.Preferably, these chemical or physical treatments are applied to guar gums, locust bean gums, starches and celluloses.

[0155] The nonionic guar gums that may be used according to the invention may be modified with Ci-Ce (poly)hydroxyalkyl groups.

[0156] Among the Ci-Ce (poly)hydroxyalkyl groups, mention may be made, by way of example, of hydroxymethyl, hydroxyethyl, hydroxypropyl and hydroxybutyl groups.

[0157] These guar gums are well known in the prior art and may be prepared, for example, by reacting corresponding alkene oxides, for instance propylene oxides, with the guar gum so as to obtain a guar gum modified with hydroxypropyl groups.

[0158] The degree of hydroxyalkylation preferably ranges from 0.4 to 1.2 and corresponds to the number of alkylene oxide molecules consumed by the number of free hydroxyl functions present on the guar gum.

[0159] Such nonionic guar gums optionally modified with hydroxyalkyl groups are sold, for example, under the trade names Jaguar HP8, Jaguar HP60 and Jaguar HP120 by the company Rhodia Chimie.

[0160] The starch molecules may be derived from any plant source of starch, notably such as com, potato, oat, rice, tapioca, sorghum, barley, pea or wheat. Use may also be made of the hydrolysates of the starches mentioned above. The starch is preferably derived from potato.

[0161] The starches may be chemically or physically modified, notably by one or more of the following reactions: pregelatinization, oxidation, crosslinking, esterification, etherification, amidation, heat treatments.

[0162] The non-associative nonionic polysaccharides of the invention may be cellulose-based polymers not including a C7 to C30 and preferably C10 to C30 fatty chain in their structure.

[0163] According to the invention, the term “cellulose-based polymer” refers to any polysaccharide compound bearing in its structure sequences of glucose residues linked together via P-1,4 bonds; in addition to unsubstituted celluloses, the cellulose derivatives may be anionic, cationic, amphoteric or nonionic.

[0164] Thus, the cellulose-based polymers that may be used according to the invention may be chosen from unsubstituted celluloses, including those in a microcrystalline form, and cellulose ethers.

[0165] Among these cellulose-based polymers, cellulose ethers, cellulose esters and cellulose ether esters are distinguished.Among the cellulose esters are mineral esters of cellulose (cellulose nitrates, sulfates, phosphates, etc.), organic cellulose esters (cellulose monoacetates, triacetates, amidopropionates, acetatebutyrates, acetatepropionates or acetatetrimellitates, etc.), and mixed organic / mineral esters of cellulose, such as cellulose acetatebutyrate sulfates and cellulose acetatepropionate sulfates. Among the cellulose ether esters, mention may be made of hydroxypropylmethylcellulose phthalates and ethylcellulose sulfates.

[0166] Among the nonionic cellulose ethers not bearing a C7-C30 fatty chain, i.e. “non-associative” cellulose ethers, mention may be made of (Ci-C4)alkylcelluloses, such as methylcelluloses and ethylcelluloses (for example Ethocel standard 100 Premium from Dow Chemical); (poly)hydroxy(Ci-C4)alkylcelluloses, such as hydroxymethylcelluloses, hydroxyethylcelluloses (for example Natrosol 250 HHR sold by Aquaion) and hydroxypropylcelluloses (for example Klucel EF from Aquaion); mixed (poly)hydroxy(Ci-C4)alkyl(Ci-C4)alkylcelluloses, such as hydroxypropylmethylcelluloses (for example Methocel E4M from Dow Chemical), hydroxy ethylmethylcelluloses, hydroxy ethylethylcelluloses (for example Bermocoll E 481 FQ from AkzoNobel) and hydroxybutylmethylcelluloses.

[0167] The non-associative nonionic polysaccharide(s) may advantageously be chosen from nonionic cellulose ethers not bearing a C7 to C30 fatty chain and mixtures thereof, more preferentially from hydroxyethylcelluloses, hydroxypropylcelluloses, ethylcelluloses and mixtures thereof, and better still ethylcelluloses and mixtures thereof.

[0413] The examples that follow serve to illustrate the invention without, however, being limiting in nature.

[0414] Examples

[0415] Example 1

[0416] Composition Al according to the invention and the comparative composition Bl, as described in the table below, were prepared. The amounts are expressed as weight percentages of active material (AM).[Table 1]

[0417]

[0418] Figure 1 in the appendix corresponds to a photograph of composition Al according to the invention 5 minutes after its preparation.

[0419] It is observed that composition Al according to the invention is a transparent gel, which is stable and perfectly homogeneous from the end of its manufacture. No syneresis was observed at room temperature (25°C) several days after the preparation of composition Al according to the invention.

[0420] Figure 2 in the appendix corresponds to a photograph of the comparative composition Bl 5 minutes after its preparation.

[0421] It is observed that the comparative composition Bl is neither homogeneous nor stable and forms crystals and gel agglomerates from the end of manufacture. Thecomparative composition Bl is opaque and remains non-homogeneous at room temperature (25 °C) several days after the preparation.

[0422] Example 2

[0423] Compositions C to E according to the invention, as described in the table below, were also prepared. The amounts are expressed as weight percentages of active material (AM).

[0424] [Table 2]

[0425]

[0426] It is observed that compositions C to E according to the invention are transparent gels, which are stable and perfectly homogeneous from the end of their manufacture.

[0427] No syneresis was observed several days after the preparation of compositions C to E according to the invention.

[0428] In addition, compositions C to E are easy to apply to keratin fibres and provide a uniform feel from the root to the end of said fibres. The disentangling of the keratin fibres is improved, and the hair is lighter, more supple and shinier.

[0429] Example 3 :

[0430] Composition A2 according to the invention and comparative composition B2, as described in the table below, were prepared. The amounts are expressed as weight percentages of active material (AM).

[0431] [Table 3]

[0432]

[0433] Compositions A2 and B2 are applied to sensitized SA20 hair locks.

[0434] The locks are first cleaned by applying a standard treatment shampoo (L'Oreal - DOP) at a rate of 0.3g of shampoo per gram of lock. The locks are kneaded until the shampoo lathers. The locks are then rinsed with water and wrung out.

[0435] Each composition A2 and B2 is applied to one of the washed and still wet locks at a rate of 0.3g of composition per gram of lock and the locks are kneaded. Without delay, the locks are then rinsed with water and wrung out twice.

[0436] After the above treatment, the hair locks were blindly evaluated by a panel of 5 experts selected and trained for the sensory evaluation of hair locks.

[0437] The evaluation of the smoothness to the touch on wet hair was carried out for each of the locks treated with one of the compositions A2 and B2.

[0438] The smoothness of wet hair was evaluated blind, as follows: each expert took a lock of hair at the root and ran it between their fingers along the entire length of the lock to the ends. The more uniform and homogeneous the hair is from root to tip, the less rough it feels, the less it snags the fingers, and therefore the smoother it feels to the touch. The hair appears more treated and repaired.

[0439] Each expert gives a score ranging from 0 to 5, in increments of 0.5.

[0440] The scores correspond to the criteria below:

[0441] 0 = very poor smoothness to the touch, the roughness of the hair is very noticeable (the hair appears untreated)

[0442] 1 = poor smoothness to the touch, the roughness of the hair is very noticeable 2 = slight smoothness to the touch, the roughness of the hair is noticeable

[0443] 2.5 = average smoothness to the touch, the roughness of the hair is moderately noticeable

[0444] 3 = quite good smoothness to the touch, the roughness of the hair is slightly noticeable 4 = good smoothness to the touch, the roughness of the hair is barely noticeable 5 = very good smoothness to the touch (no roughness of the hair is noticeable to the touch: the composition has treated the hair perfectly)

[0445] The results are as follows:[Table 4]

[0446]

[0447] It is observed that the hair treated with the composition A2 according to the invention is smoother to the touch than the hair treated with the comparative composition B2.
