Description

Title of the invention: HAIR CARE COMPOSITION BASED ON VEGETABLE WAX AND SPECIAL CATIONIC SURFACTANTS

[0001] The present invention relates to a composition, in particular a hair care product comprising at least one vegetable wax, at least one first cationic surfactant selected from fatty amines and at least one second cationic surfactant of the ammonium diester type.

[0002] The invention further relates to a cosmetic treatment process for keratinous materials comprising a step of applying to said keratinous materials at least one composition as defined later.

[0003] Hair can be weakened or damaged by the action of external atmospheric agents such as light and inclement weather, or by mechanical or chemical treatments such as brushing, combing, dyeing, bleaching, perming, and / or straightening. To remedy these problems, it is common to use hair care products that condition the hair. These hair care products can be conditioning shampoos or conditioners, which may be in the form of gels, hair lotions, or creams of varying thicknesses.

[0004] To improve the cosmetic properties of these compositions, particularly those intended for sensitized hair, it is known to introduce silicones into them. Silicones do indeed improve cosmetic properties, including detangling, softness to the touch, and hair volume, while preserving and strengthening the intrinsic mechanical properties of keratin fibers, such as tensile strength, breaking load and elasticity, or their resistance to swelling in an aqueous environment.

[0005] However, the presence of silicone has several disadvantages: the environmental profile (biodegradability, water footprint) is not always optimal, the appearance of the composition is generally opaque (not very aesthetic), and the hair becomes greasy quickly and is often weighed down.

[0006] In addition, repeated applications of these compositions often result in an unpleasant feel to the hair, a loss of volume and bounce in the hair, and sometimes a lack of shine.

[0007] Furthermore, research on texture has played a central role in cosmetics for years in the development of creams for the body, face, hands, etc., but remains very underdeveloped in the hair care field and particularly in the field of hair care. As a result, current hair care formulations generally do not have textures that are pleasant to the touch for consumers, specifically one that is both firm and melts into the skin.

[0008] Indeed, current compositions, which generally have a thick texture, are not very meltable and are difficult to distribute evenly on keratinous materials, in particular keratinous fibers such as hair.

[0009] From these observations arose the interest in developing a hair care composition advantageously without silicone (“silicone-free” in English), presenting improved qualities of use, in particular a firm and melting texture which is easy to apply on the keratin fibers, which spreads easily on the fibers, and “melts” quickly on application, as well as good cosmetic properties, in particular which is able to repair the ends of the hair and give the keratin fibers softness to the touch, suppleness, and a smooth feel.

[0010] It is of particular interest to succeed in developing a composition which has both a firm and melting texture upon application, which allows for a homogeneous deposition of the composition on keratinous materials, and more preferentially on keratinous fibers such as hair.

[0011] Furthermore, the formulation of environmentally friendly cosmetic products, that is to say, whose design and development take into account environmental issues, is becoming a major concern in order to help meet global challenges.

[0012] It is therefore essential to propose more sustainable compositions and / or preparation processes and / or ingredients, thus enabling us to meet these environmental challenges.

[0013] In this context, it is important to develop new cosmetic compositions with a better carbon footprint, in particular by promoting the use of renewable raw materials and / or with a good naturalness index and / or of natural origin and more particularly of plant origin, while reducing the use of petrochemical compounds.

[0014] These objectives are achieved with the present invention, which relates in particular to a composition, preferably cosmetic, in particular hair care, comprising:

[0015] (i) at least one vegetable wax, (ii) at least one first cationic surfactant selected from fatty amines, and (iii) at least one second cationic surfactant of the following formula (A): in which: - Ri and R2 represent, independently of each other, a C7-C4o hydrocarbon group, linear or branched, saturated or unsaturated, - R3 and R4, independently of each other, are chosen from a) alkyl groups in C1-C4, b) hydroxyalkyl groups in Ci-C4, and c) dihydroxyalkyl groups in CrC4, - A and A' represent, independently of each other, an alkyl group in Ci-C6, and - X represents an anion.

[0016] It has been observed that the composition according to the invention has good performance qualities and good cosmetic properties, in particular a good coating of the keratin fibers by the composition, giving them good protection against the action of external atmospheric agents such as light and weathering, or by mechanical or chemical treatments such as brushing, combing, dyeing, bleaching, perming and / or straightening, and allowing the asperities of said fibers to be effectively eliminated to the touch.

[0017] The composition according to the invention also has a differentiating texture compared to hair care compositions usually used, with a very thick (very firm) balm texture and particularly melts upon application, especially upon contact with keratin fibers such as hair.

[0018] The composition according to the invention succeeds in presenting a firm and melting texture upon application, while allowing homogeneous deposition of the latter on keratinous materials, in particular keratinous fibers such as hair.

[0019] The melting refers in particular to the ability of the product to become fluid upon contact with hair materials during its application.

[0020] In addition, it has been observed that the composition according to the invention makes it possible to repair the ends of the hair and gives the keratin fibers softness to the touch, suppleness, and smoothness to the touch.

[0021] Furthermore, the applicant also noted that the composition according to the invention can advantageously be formulated without silicone compounds, without giving up the advantageous properties mentioned above.

[0022] The invention also relates to a cosmetic treatment process, in particular for hair, comprising at least one application step on keratinous materials, in particular keratinous fibers of at least one composition as described later.

[0023] Other objects, features, aspects and advantages of the invention will become even clearer upon reading the description and example that follows.

[0024] In this description, and unless otherwise indicated: - the expression "at least one" is equivalent to the expression "one or more" and can be substituted for it. - the expression "between... and..." is equivalent to the expression "ranging from... to..." and can be substituted for it, and implies that the limits are included. - By the expression "greater than" and respectively the expression "less than" in the meaning of the present invention, we mean an open interval that is strictly greater than, respectively strictly less than, and therefore that the bounds are not included. - For the purposes of this application, "keratinous materials" means more particularly 1) the skin of the body and / or face (including the scalp) and / or nails, and 2) keratinous fibers; and even more particularly the scalp and hair. - For the purposes of this application, "keratin fibers" refers particularly to human keratin fibers such as hair, eyelashes, eyebrows, and body hair, preferably hair, eyebrows and eyelashes, and even more preferably hair. - For the purposes of this invention, "hair" means the hair on the head. This term does not include body hair, eyebrows, or eyelashes. - For the purposes of this application, "fatty acid" means an organic acid comprising in its structure a hydrocarbon chain, linear or branched, saturated or unsaturated, comprising from 6 to 40 carbon atoms, preferably from 8 to 30 carbon atoms, more preferably from 10 to 22 carbon atoms. - For the purposes of this application, "fatty alcohol" means an alcohol comprising in its structure a hydrocarbon chain, linear or branched, saturated or unsaturated, comprising from 6 to 40 carbon atoms, preferably from 8 to 30 carbon atoms, more preferably from 10 to 22 carbon atoms.

[0025] Preferably, the composition according to the invention is free of silicone.

[0026] By the expression "silicone-free", it is understood that the composition according to the invention does not include silicone, or that the silicone(s) present in the composition according to the invention are included in a total content less than or equal to 0.1% by weight, preferably less than 0.05% relative to the total weight of the composition according to the invention, better silicone-free (0%).

[0027] The term “silicone” means all organosilicon polymers or oligomers with a linear or cyclic, branched or cross-linked structure, of varying molecular weight, obtained by polymerization and / or polycondensation of suitably functionalized silanes, and consisting essentially of a repetition of principal motifs in which silicon atoms are linked together by oxygen atoms (siloxane bond -Si-O-Si-), with optionally substituted hydrocarbon radicals being directly linked via a carbon atom to said silicon atoms; and more specifically dialkylsiloxane polymers, amino silicones, dimethiconols.

[0028] Preferably, the composition according to the invention is free of anionic surfactant.

[0029] By the expression "devoid of anionic surfactant", it is understood that the composition according to the invention does not include anionic surfactant, or that the anionic surfactant(s) present in the composition according to the invention are included in a total content less than or equal to 0.1% by weight, preferably less than 0.05% relative to the total weight of the composition according to the invention, better free of anionic surfactant (0%).

[0030] By "anionic surfactant" is meant a surfactant comprising only anionic groups as ionic or ionizable groups.

[0031] In the present description, an entity is qualified as "anionic" when it has at least one permanent negative charge or when it can be ionized into a negatively charged entity, under the conditions of use of the composition of the invention (medium, pH for example) and not comprising a cationic charge.

[0032] Vegetable waxes: The composition according to the invention comprises at least one vegetable wax.

[0033] A wax, in the sense of the present invention, is a lipophilic compound, solid at room temperature (25°C) and atmospheric pressure (1.013.105 Pa), with a reversible solid / liquid change of state, having a melting temperature above about 40°C and up to 200°C, and exhibiting in the solid state an anisotropic crystalline organization.

[0034] In particular, the wax(s) suitable for the invention may have a melting point greater than or equal to 45°C, and in particular greater than or equal to 55°C, and especially up to 120°C. More particularly, the wax(s) suitable for the invention may have a melting point greater than or equal to 45°C, and in particular greater than or equal to 55°C.

[0035] For the purposes of this invention, the melting point corresponds to the temperature of the most endothermic peak observed in differential scanning calorimetry (DSC) as described in ISO 11357-3; 1999. The melting point of the crystallizable fat can be measured using a differential scanning calorimeter (DSC), for example, the calorimeter sold under the name MDSC 2920 by TA Instruments. Such a measurement method is described, for example, in document WO 2013190080.

[0036] Generally speaking, the size of the wax crystals is such that the crystals diffract and / or diffuse light, giving the composition containing them a cloudy, more or less opaque appearance. By heating the wax to its melting point, It is possible to make it miscible with oils and to form a microscopically homogeneous mixture, but by bringing the temperature of the mixture back to room temperature, a recrystallization of the wax is obtained, detectable microscopically and macroscopically (opalescence).

[0037] The vegetable wax(s) may be unmodified (native) or modified (for example hydrogenated); unmodified vegetable waxes are preferred.

[0038] A vegetable wax, within the meaning of the present invention, is a wax obtained from plants, for example extracted from leaves, flowers, fruits, peel (for example of citrus fruits), seeds or stems.

[0039] Examples include jojoba wax, rice bran wax (Oryza sativa cera), carnauba wax (Copemicia cerifera cera), candelilla wax (Candelilla cera), sunflower wax (Helianthus annuus seed cera), Ouricury wax, alfa wax, berry wax, shellac wax, Japanese wax and sumac wax; Montan wax, orange and lemon waxes, mimosa flower wax (Acacia decurrens flower cera), absolute flower waxes such as blackcurrant flower essential wax sold by the company BERTIN (France).

[0040] We can also mention waxes obtained by catalytic hydrogenation of vegetable oils having linear or branched fatty chains, in C8 to C32. Among these, we can notably mention isomerized jojoba oil, such as trans isomerized partially hydrogenated jojoba oil, in particular that manufactured or marketed by the company Desert Whale under the trade reference Iso-Jojoba-50®, hydrogenated sunflower oil, hydrogenated castor oil and hydrogenated coconut oil.

[0041] Waxes obtained by hydrogenation of esterified castor oil with cetyl alcohol can also be used, such as those sold under the names Phytowax ricin 16L64® and 22L73® by the company SOPHIM.

[0042] It is also possible to use micro-waxes, in particular carnauba micro-waxes, such as that marketed under the name MicroCare 350® by the company MICRO POWDERS.

[0208] The following examples serve to illustrate the invention without, however, being intended to be limiting. Examples#:

[0209] Example 1: Composition A according to the invention and the comparative composition B as described in the table below were prepared. The quantities are expressed as % by weight of active ingredient (ma).

[0210] [Tables 1] Ingredients A (invention) B (comparative) Jojoba wax(1) 5 - Jojoba butter(2) - 5 Stearamidopropyl dimethylamine 1 1 Distearoylethyldiimonium chloride 2.9 2.9 Cetearyl alcohol 9.5 9.5 Glycerin 0.5 0.5 Lactic acid 0.3 0.3 Preservatives qs qs Fragrance qs qs Water qsp 100 qsp 100

[0211] (1) melting point = 50°C (2) melting point = 35°C

[0212] Thick creams are obtained, white in color and with a smooth and shiny appearance, which can be used as a rinse-off hair care composition (such as conditioner, after-shampoo, mask...).

[0213] Application protocol for sensory evaluation:

[0214] The above compositions are applied to SA20 sensitized Caucasian hair strands.

[0215] The strands are pre-cleaned by applying a standard treatment shampoo (L'Oréal Paris - Elseve DreamLong Reconstructing Shampoo) at a rate of 0.3g of shampoo per gram of strand. The strands are massaged until the shampoo lathers. The strands are then rinsed with water.

[0216] Each composition A and B is applied to one of the washed and still wet strands, at a rate of 0.45g of composition per gram of strand, then the strands are left to air dry for 5 minutes. The strands are then rinsed with water for 10 seconds.

[0217] Sensory evaluation protocol and results obtained:

[0218] In application, experts note that the melting character of the composition is more marked for the composition according to the invention than for the comparative composition.

[0219] After the above treatment, the hair strands were evaluated blindly by a panel of 6 people selected and trained for the sensory evaluation of hair strands.

[0220] The evaluation was carried out on the coating of the compositions on wet hair.

[0221] The evaluation is carried out blindly, as follows: the expert takes the take a strand of hair and slide your fingers from root to tip, and thus assess the presence and homogeneity of a deposit.

[0222] Each expert gives a score from 0 to 5, in increments of 0.5. The more significant and homogeneous the deposit, the better the hair is coated and the better the hair's imperfections are masked.

[0223] The scores correspond to the criteria below: 0 = very poor coating of the hair by the composition, the roughness of the hair is very strongly felt (the hair appears untreated) 1 = hair very lightly coated by the formula, the hair's roughness is strongly felt 2 = hair not very coated by the formula, the hair's texture is clearly visible 3 = hair is moderately coated by the formula; the hair's roughness is moderately felt. 4 = hair is well coated by the formula, and any roughness in the hair is barely noticeable. 5 = hair very well coated by the formula (no more roughness of the hair is perceptible to the touch: the formula has perfectly treated the hair)

[0224] The rating of 3 is given for reference to the comparative composition.

[0225] The results are as follows:

[0226] [Tables2] Individualization A (Invention) B (Comparative) Expert 1 4 3 Expert 2 4 3 Expert 3 3.5 3 Expert 4 4 3 Expert 5 3.5 3 Expert 6 4 3 Mean 3.8 3 Standard deviation 0.2 0.0

[0227] These results show an improvement in hair coating with the composition according to the invention compared to the coating obtained with the comparative composition.

[0228] Hair treated with the composition according to the invention appears better treated, with less aporia and is more repaired than hair treated with the comparative composition.

[0229] Example 2: Composition C according to the invention, as described in the table below, was prepared. Quantities are expressed as % by weight of active ingredient (ma). Ingredients C (invention) Rice bran wax 1.8 Stearamidopropyl dimethylamine 0.8 Distearoylethyl dimonium chloride 2.5 Cetearyl alcohol 6.7 Glycerin 0.5 Cetyl esters 2 C10-C18 triglycerides 5 Lactic acid 0.3 Preservatives qs Parfum qs Water qsp 100

[0230] Composition C spreads easily on the hair and has a very good melting character upon application.

[0231] It leads to very good cosmetic properties, particularly in terms of homogeneous coating of the fiber and the smooth feel of the hair. It is also noted that hair treated with composition C according to the invention has more body.
