Description

[0001] DESCRIPTION

[0002] TITLE: Cosmetic composition comprising a cationic surfactant of fatty amine type and a combination of esters in a particular weight ratio

[0003] The present invention relates to a cosmetic composition, in particular hair composition, comprising at least one cationic surfactant of fatty amine type, at least one liquid non-oxyethylenated sorbitan ester, at least one ester of a fatty acid and a fatty alcohol, with a specific weight ratio of the total content of the liquid non-oxyethylenated sorbitan ester(s) to the total content of the ester(s) of fatty acids and fatty alcohols.

[0004] The invention also relates to a method for the cosmetic treatment, preferably the care and / or conditioning, of keratin fibers, preferably human keratin fibers, more preferentially the hair, comprising the application to said keratin fibers of said cosmetic composition.

[0005] The invention also relates to the use of said cosmetic composition for the cosmetic treatment, preferably the care and / or conditioning, of keratin fibers, preferably human keratin fibers, more preferentially the hair.

[0006] Technical field

[0007] Natural hair or hair that has been treated via various chemical treatments may be dull, lacking care, 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, dyeing, bleaching, permanent- waving and / or relaxing, and repeated washing.

[0008] The hair thus ends up lacking care as regards natural hair, or damaged by these various factors, and may in the long run become dry, coarse, brittle, dull, split and / or limp.

[0009] To overcome these drawbacks, it is common practice to resort to hair care products using compositions intended to care for and / or condition the hair appropriately, giving it satisfactory cosmetic properties, especially in terms of smoothness, sheen, suppleness, good coating and good disentangling properties.

[0010] These haircare compositions may be, for example, conditioning shampoos, hair conditioners, masks, creams or serums.

[0011] However, these haircare compositions are not always entirely satisfactory in terms of visual esthetics such as the sheen, and a soft and natural feel.In addition, the current compositions generally have a thick, non-melting texture and they are difficult to spread uniformly over the keratin materials, in particular the keratin fibers such as the hair, without running.

[0012] Thus, there is a need to provide a melting composition which is easily applied to and spread over keratin fibers and which makes it possible to give them improved cosmetic properties, in particular conditioning properties, such as smoothness, sheen, suppleness, slip, disentangling properties leading to easy combing, and also good coating.

[0013] Moreover, the formulation of environmentally friendly cosmetic products, i.e., products designed and developed while taking account of environmental issues, is becoming a major concern in helping to meet global challenges.

[0014] It is therefore essential to propose more sustainable compositions and / or preparation processes and / or ingredients, thus enabling these environmental challenges to be met.

[0015] In this context, it is important to develop new cosmetic compositions with a better carbon footprint, in particular by promoting the use of starting materials that are renewable and / or that have a good naturality index and / or that are of natural origin and more particularly of plant origin, while reducing the use of compounds of petrochemical origin.

[0016] The applicant has thus discovered, surprisingly, that the combination of at least one cationic surfactant of fatty amine type with at least one liquid non-oxyethylenated sorbitan ester and at least one ester of a fatty acid and a fatty alcohol, in a particular weight ratio, made it possible to meet these needs.

[0304] Another subject of the present invention is the use of the composition as described previously, for the cosmetic treatment, preferably the care and / or conditioning, of keratin fibers, preferably human keratin fibers, more preferentially the hair.

[0305] More particularly, the composition according to the invention is used as a hair conditioner, notably as a hair mask.

[0306] The examples that follow serve to illustrate the invention without, however, being limiting in nature.Examples

[0307] Example 1

[0308] Compositions A and B according to the invention and comparative composition C as described in table 1 below were prepared: the amounts are expressed as % by weight of active material (% AM) relative to the total weight of the composition.

[0309] [Table 1]

[0310]

[0311] Light creams were obtained, which were white in color and smooth and shiny in appearance, and which can be used as a rinse-out haircare composition (cream rinse, conditioner, mask, etc.).

[0312] Application protocol for the sensory evaluation

[0313] Locks of AS20 sensitized Caucasian hair were precleaned by applying a standard treatment shampoo (L’Oreal Paris - Elseve Dream Long Restoring Shampoo) in a proportion of 0.3 g of shampoo per gram of lock. The locks were massaged until the shampoo was worked into a lather. The locks were then rinsed with water.

[0314] Each composition A and C was applied to one of the washed and still wet locks, in a proportion of 0.45 g of composition per gram of lock, then the locks were left in the open air for 5 minutes. The locks were then rinsed with water for 20 seconds.Sensory evaluation and results obtained:

[0315] On application, the experts noted that the melting character of the composition was more marked for composition A according to the invention than for comparative composition C.

[0316] A sensory evaluation of the conditioning properties of each wet treated lock was carried out blind. For this purpose, the expert compares the lock of hair treated with comparative composition C with the lock of hair treated with composition A according to the invention, under blind conditions.

[0317] The expert then grades the lock of hair treated / washed with comparative composition C, according to the following scores:

[0318] +2: very significantly better than with composition A according to the invention, +1: significantly better than with composition A according to the invention,

[0319] 0: similar to the lock treated with composition A according to the invention,

[0320] -1: significantly worse than with composition A according to the invention,

[0321] -2: very significantly worse than with composition A according to the invention.

[0322] The score of 0 is given to the lock treated with composition A according to the invention.

[0323] Then, after evaluation on wet hair, the locks were dried using a hair dryer before an evaluation on dry hair.

[0324] The same protocols as those for wet hair were used.

[0325] Evaluation of smoothness to the touch:

[0326] The expert takes a lock of hair at the root and slides it between the fingers over the entire length of the lock as far as the ends. The more uniform and homogeneous the hair from the root to the end, the fewer rough patches it has, the less it catches on the fingers, and therefore the better the smoothness to the touch.

[0327] Evaluation of suppleness:

[0328] The expert takes a lock of hair in both hands and attempts to fold it. The more easily the hair can be folded or bent, the more pliable it is, and therefore the better the suppleness.

[0329] Evaluation of disentangling:The expert takes a lock of hair and evaluates the ease with which a fine comb passes through the hair, while sliding it from the root to the end. The more easily the fine comb passes through, the better the disentangling.

[0330] Evaluation of slip:

[0331] The expert takes a lock of hair at the root and slides it between the fingers over the entire length of the lock from the root to the end. The more lubricated the fiber, the easier and faster the fingers slide, and therefore the better the slip.

[0332] The results are collated in table 2 below:

[0333] [Table 2]

[0334]

[0335] These results show that the application of the composition according to the invention leads to an improvement in the suppleness, disentangling and smoothness of the hair compared with the application of the comparative composition, both on dry hair and on wet hair.

[0336] In addition, these results show an improvement in the slip on dry hair with the composition according to the invention compared with the results obtained with the comparative composition.

[0337] The hair treated with the composition according to the invention appears better treated, with fewer rough patches and is more repaired than the hair treated with the comparative composition.

[0338] Example 2

[0339] Composition D according to the invention and comparative compositions E and F as described in table 3 below were prepared: the amounts are expressed as % by weight of active material (% AM) relative to the total weight of the composition.

[0340] [Table 3]

[0341]

[0342] Application protocol for the sensory evaluation

[0343] Locks of AS20 sensitized Caucasian hair were precleaned by applying a standard treatment shampoo (L’Oreal Paris - Elseve Dream Long Restoring Shampoo) in a proportion of 0.5 g of shampoo per gram of lock. The locks were massaged until the shampoo was worked into a lather. The locks were then rinsed with water.

[0344] Each of the compositions D to F was applied to one of the washed and still wet locks, respectively, in a proportion of 0.9 g of composition per gram of lock, then the locks were left in the open air for 5 minutes. The locks were then rinsed with water for 20 seconds.

[0345] Sensory evaluation and results obtained:

[0346] A sensory evaluation of the conditioning properties of each wet treated lock was carried out blind by experts. For this purpose, the expert compares, under blind conditions:

[0347] - the lock of hair treated with comparative composition E with the lock of hair treated with composition D according to the invention;

[0348] - the lock of hair treated with comparative composition F with the lock of hair treated with composition D according to the invention.

[0349] The expert then grades the lock of hair treated / washed with comparative compositions, according to the following scores:

[0350] +2: very significantly better than with composition D according to the invention, +1: significantly better than with composition D according to the invention,

[0351] 0: similar to the lock treated with composition D according to the invention,-1: significantly worse than with composition D according to the invention,

[0352] -2: very significantly worse than with composition D according to the invention.

[0353] The score of 0 is given to the lock treated with composition D according to the invention.

[0354] The results are collated in table 4 below:

[0355] [Table 4]

[0356]

[0357] These results show that the application of the composition according to the invention leads to an improvement in the suppleness and smoothness of the hair compared with the application of the comparative composition, on wet hair.
