Description

Cosmetic composition comprising a cationic galactomannan, specific anionic surfactants and a glucamide, and cosmetic treatment process

[0001] The present invention relates to a cosmetic composition comprising specific cationic polymers, specific anionic surfactants and glucamides. The invention also relates to a process for treating, notably washing, keratin materials, notably the hair, using said composition.

[0002] For cleansing and / or washing the hair, it is known to use liquid detergent haircare compositions (or shampoos) which are essentially based on conventional surfactants; notably anionic, nonionic and / or amphoteric, but generally anionic, surfactants. These compositions are applied to wet hair and the foam generated by massaging or rubbing with the hands makes it possible, after rinsing with water, to remove the various types of soiling initially present on the hair.

[0003] Among the anionic surfactants which may be used, mention may notably be made of sulfate surfactants, such as alkyl sulfate or alkyl ether sulfate salts. These surfactants are known to generate abundant foam, making it possible to easily remove soiling by dispersing it in water, leading to a feeling of cleanliness.

[0004] In order to preserve natural resources and notably water, it is advantageous to propose compositions that make it possible to reduce the amount of water needed, notably during use of the product, in particular for rinsing out said product.

[0005] In addition, the formulation of environmentally-friendly cosmetic products, i.e. products whose design and development take account of environmental issues, is becoming a major preoccupation for contributing towards meeting the global challenges.

[0006] It is therefore essential to propose compositions and / or preparation processes and / or ingredients that make it possible to respond to these environmental challenges. In this context, it is important to develop novel cosmetic compositions with a better carbon footprint, notably by promoting the use of starting materials that are renewable and / or that have a good naturalness index and / or that are of natural origin and more particularly of plant origin, while reducing the use of compounds of petrochemical origin.

[0007] There is therefore a real need to propose cosmetic compositions which are easy to rinse, notably in order to save on water during rinsing, while retaining both good properties of use, such as a good intrinsic washing power and good foam quality (abundance, creaminess notably) and also excellent cosmetic properties, in particular in terms of suppleness, disentangling, smoothness to the touch and coating the treated hair.

[0008] It is possible to solve these problems and achieve these aims by virtue of the present invention, one subject of which is notably a cosmetic composition comprising:

[0009] (a) one or more cationic galactomannans,

[0010] (b) one or more sulfate anionic surfactants,

[0011] (c) one or more anionic surfactants of formula (I): R-X-L-Y-A+

[0012] wherein:

[0013] - R is a linear or branched alkyl group comprising from 6 to 30 carbon atoms;

[0014] - X is a divalent radical chosen from -O-C(O)- and -C(O)-NH-,

[0015] - L is a linear or branched divalent alkyl group comprising from 1 to 4 carbon atoms;

[0016] - Y-is a sulfonate SO3-or carboxylate COO-group, and

[0017] - A+is a cosmetically acceptable counterion, and

[0018] (d) one or more glucamide compounds.

[0019] The composition according to the invention is particularly easy to rinse, notably but not only by virtue of the use of specific surfactants as a replacement for part of, or in addition to, the customary sulfate surfactants.

[0020] The composition according to the invention makes it possible to substantially reduce the environmental impact thereof compared to a conventional washing composition based on sulfate surfactants, notably in terms of saving on water.

[0021] Moreover, the composition according to the invention has good qualities of use; notably, it makes it possible to generate an adequate amount of good quality foam, in particular having a pleasant creaminess (creamy foam).

[0022] In addition, the composition according to the invention makes it possible to impart good cosmetic properties to the treated hair: the hair is particularly supple, easy to disentangle, has a smoothness to the touch, and is adequately coated.

[0023] In the present description, and unless otherwise indicated:

[0024] - the expression "at least one" is equivalent to the expression "one or more" and can be replaced therewith;

[0025] - the expression “between” is equivalent to the expression “ranging from” and can be replaced therewith, and implies that the limits are included;

[0026] - the term “keratin materials” denotes keratin fibres, and in particular the hair, the eyelashes, the eyebrows, the skin, the nails, the mucous membranes or the scalp;

[0027] - according to the present patent application, the term “keratin fibres” denotes human keratin fibres and more particularly the hair.Cationic galactomannans

[0030] Said cationic polymers can be associative or non-associative; a mixture of such polymers can also be used. Preferably, the cationic galactomannan gums are non-associative.

[0031] Said polymers are not silicone-based (they do not comprise any Si-O units).

[0032] Advantageously, the cationic galactomannans are chosen from guar gums comprising cationic trialkylammonium groups, notably C1-4 alkyl, for example methyl.

[0033] Mention may notably be made of guar gums modified with a 2,3-epoxypropyltrimethylammonium salt (for example a chloride).

[0234] Compositions which can be used as a shampoo to be rinsed out, for washing the hair, are obtained.A / Evaluation of the cosmetic performance

[0235] The cosmetic performance in terms of smoothness to the touch provided by compositions A and B is evaluated.

[0236] Each of the compositions A and B was applied to locks of wet hair (5.4 g locks, SA20 sensitized) in an amount of 0.6 g of composition per gram of lock. The locks were rinsed without any leave-on time. Evaluation on wet locks was carried out.

[0237] A score of 0 was awarded to locks treated with comparative composition B, and a score ranging from -3 to +3 in increments of 0.5 was awarded to the locks treated with composition A. The comparative evaluation was carried out blind by 3 experts.

[0238] Each whole score corresponds to the following elements:

[0239] + / - 3: large difference

[0240] + / - 2: medium difference

[0241] + / - 1: small difference

[0242] 0: equivalent (no difference).

[0243] The results are considered to be better when the score is positive, and worse when the score is negative.

[0244] The nature of smoothness to the touch was evaluated as follows: touch evaluation of the uniformity of the hair from root to tip, by holding a lock of hair at the root and sliding it through the fingers as far as the tip; the more the feeling is uniform, the better the smoothness to the touch.

[0245] The following results are obtained (mean of 3 scores):

[0246] Smoothness to the touch on wet hairA (invention)B (comparative)Expert 1+20Expert 2+20Expert 3+10Mean+1.670Standard deviation0.580

[0247] With the application of composition A according to the invention, it can be observed that the hair has a greater smoothness to the touch compared to the comparative composition B.B / Evaluation of rinsability performance

[0248] In order to evaluate rinsability performance, three drops of artificial sebum were applied using a pipette to locks of hair (5.4 g, SA20 sensitized) and distributed over the whole length of the lock. The locks were then wet, then dried manually.

[0249] 0.25 g of the composition to be tested were then applied to the lock. The lock was then rinsed until the feeling when touched no longer changed, i.e. until there was no more sebum on the lock.

[0250] The time required for rinsing each lock was compared to that obtained with a reference shampoo (Garnier Fructis Aloe Hydrabomb). The shorter the rinsing time, the easier the rinsing is.

[0251] Each expert (3 experts) awarded a score corresponding to the rinsing times, ranging from -3 to +3, with an increment of 0.5, to the locks to be evaluated, using the same scoring scale as described previously. A score of 0 is awarded to the reference composition.

[0252] The following results are obtained (mean of 3 scores):

[0253] RinsabilityA (invention)B (comparative)ReferenceExpert 1+1-20Expert 2+1-1.50Expert 3+1-20Mean+1-1.80Standard deviation00.30

[0254] It is noted that composition A according to the invention is easier to rinse than the comparative composition and the reference composition.

[0255] Hair washed with the composition according to the invention also has better cosmetic properties, notably a smoother feel on wet hair than comparative composition B.
