Description

Title of the invention: Cosmetic composition comprising a bis-amino silicone, an amino silicone, a fatty chain cationic surfactant and a fatty ester, and method

[0001] The present invention relates to a cosmetic composition comprising a combination of particular silicones, one or more particular cationic surfactants and one or more fatty esters. The invention also relates to a method for the cosmetic treatment of keratin materials, in particular hair, using said composition.

[0002] Hair is generally damaged and weakened by the action of external atmospheric agents such as light and bad weather, as well as by mechanical or chemical treatments such as brushing, combing, dyeing, bleaching, perming and / or straightening, or even repeated washing.

[0003] The hair is thus damaged by these different factors and can in the long run become dry, rough, brittle or dull, particularly in fragile areas, and more particularly at the ends.

[0004] Thus, to overcome these drawbacks, it is customary to use hair care compositions, in particular intended to condition the hair by providing it with satisfactory cosmetic properties. These hair compositions may be, for example, conditioners, masks or serums, and may be in the form of gels, hair lotions and care creams of varying thickness.

[0005] It is particularly known to use compositions in the form of oily masks or serums containing combinations of oils, silicone and / or non-silicone. However, such compositions still too often lead to excessive greasing of the keratin fibers, which can result in a greasy or even sticky feel to them, and a heavy and loaded visual appearance.

[0006] Furthermore, compositions containing oils, once applied to the hair, frequently lead to unpleasant effects to the touch, in particular the hair tends to be rough and / or to "squeak" (i.e. produce an unpleasant sound effect) in particular when rubbing the hair together while sliding the fingers along the hair from root to tip.

[0007] Furthermore, hair treated with such compositions is not easy or quick to dry.

[0008] Finally, the immediate benefits provided by such compositions are not always sufficient for the most damaged hair and / or tend to fade quickly in over time, or even disappear after shampooing.

[0009] The present invention aims to provide compositions which do not have the drawbacks mentioned above, and which are capable of providing good conditioning properties to the hair, such as a natural and clean feel, a smooth character to the touch and / or visual appearance, shine, softness, flexibility, lightness, a homogeneous coating of the fiber, as well as good detangling properties; these properties being advantageously long-lasting over time.

[0010] The present invention therefore relates in particular to a cosmetic composition, in particular for hair, comprising: (i) one or more alpha,omega-bis-amino silicones, (ii) one or more amino silicones, other than alpha,omega-bis-amino silicones (i),

[0011] (iii) one or more cationic surfactants comprising at least two fatty chains, and

[0012] (iv) one or more fatty esters,

[0013] the weight ratio between the total content of alpha-omega bis-amino silicone(s) (i) on the one hand, and the total content of amino silicone(s) (ii) different from the silicones (i) on the other hand, preferably being greater than or equal to 1.

[0014] The composition according to the invention makes it possible to confer good cosmetic properties on the hair, in particular to provide a very good level of hair care to the hair, in particular to weakened or damaged hair, in particular in terms of smoothness to the touch and visually, softness, suppleness, or even strengthening and / or repair of the hair, in particular damaged ends.

[0015] The composition according to the invention has good qualities of use. It is easy to apply, to spread on the keratin fibers and melts on application.

[0016] If necessary, it is easily removed by simply rinsing the keratin fibers, without leaving them with a greasy feel or appearance.

[0017] Even without rinsing the composition, when it is used as a leave-on for example, the fibers remain light, uncharged and non-sticky, and have a clean feel.

[0018] In addition, this composition has good durability of effects over time (at least for 24 hours) and good persistence of effects, for example after at least one shampoo.

[0019] In particular, the composition according to the invention makes it possible to give the hair, upon application, properties of smoothness, softness, suppleness and lightness; after 1 shampoo, the level of care provided by the composition according to the invention remains very high, in particular on dry hair, on which it is noted that the smooth (slippery) feel is always present, and in a homogeneous manner from the roots to the ends. hair.

[0221] After applying the composition according to the invention, the keratin materials can be rinsed with water, before being dried or left to dry. Preferably, there is no rinsing step.

[0222] The following examples serve to illustrate the invention without, however, being limiting in nature. Example 1

[0223] The hair care compositions according to the invention (A) or comparative compositions (B1 and B2) are prepared from the following ingredients (% by weight of active material MA):

[0224] [Tables 1] Ingredients A B1 B2 Bis-aminopropyl dimethicone 0.07 0.07 0.07 Amodimethicone 0.03 0.03 0.03 Dicetyldimonium chloride 1 1 1 Cetyl esters 1 - - Cetearyl alcohol 6 6 7 Cetrimonium chloride 1 1 1 Water Qsp 100 Qsp100 Qsp 100

[0225] The compositions thus obtained can be used as a hair care composition, to be rinsed; in particular they can be applied to damp hair previously washed with shampoo and rinsed.

[0226] They can advantageously be applied to damaged hair.

[0227] The quantity of silicon deposited on dried hair is determined by compositions A, B1 and B2; the quantity is measured by X-ray fluorescence spectrometry. mass concentration of silicon element on the hair fiber.

[0228] The composition to be tested is applied to natural locks of hair, previously washed and still damp, at a rate of 0.4g of composition per g of lock; it is left to act for 2 minutes then the lock is rinsed with water for 10 seconds [flow rate = 300 1 / h - Temperature = 38°C] and the locks are dried in a study at 60°C for 30 minutes.

[0229] The quantity of silicon is measured for each of the treated strands.

[0230] The amount of silicon deposited corresponds to the amount of silicon measured at from which we subtract the quantity of silicon present on untreated natural hair (silicon content = measured content - natural silicon content).

[0231] The following results are obtained (average over 3 strands):

[0232] [Tables2] A B1 B2 Quantity of silicon deposited 126 ppm 87 ppm 93 ppm Standard deviation 15 1 22

[0233] It is noted that composition A according to the invention makes it possible to deposit a greater quantity of silicon on the locks of hair in comparison with composition B1 which does not comprise fatty esters, and also with composition B2 which comprises an identical total content of fatty substances (fatty alcohol + fatty ester), but does not comprise fatty ester.

[0234] 2 / The cosmetic performance on wet hair of compositions A and B2.

[0235] Apply 0.4g of Total Repair 5 treatment shampoo (ELSEVE - L'OREAL PARIS) per g of strand sensitized by a bleaching treatment, knead and lather; leave on for 30 seconds then rinse the strand with water for 15 seconds [flow rate = 3001 / h - Temperature = 35°C].

[0236] On washed and still wet hair, apply 0.4 g of the composition to be tested per g of strand; leave for 2 minutes then rinse the strand with water for 10 seconds [flow rate = 3001 / h - Temperature = 35°C].

[0237] The sensory cosmetic performances provided by compositions A and B2 are evaluated on damp hair after rinsing.

[0238] The criteria evaluated are smoothness to the touch and flexibility.

[0239] The evaluation is done blindly by 5 evaluators, who give a score ranging from 0 (very bad) to 5 (very good), in steps of 0.5.

[0240] Smoothness assessment: The assessor takes a lock of hair at the root and slides it between the fingers along the entire length of the lock to the tips. The more uniform and consistent the hair is from root to tip, the fewer rough spots it has, the less it catches the fingers, the better the smoothness to the touch.

[0241] Evaluation of flexibility: the evaluator takes the hair in both hands and tries to bend it. The more easily the hair can be bent and curved, the more malleable it is, the better the flexibility.

[0242] [Tables3] A B2 Smooth Touch 4.5 3.5 Flexibility 4 3

[0243] It is noted that the composition according to the invention provides performance in terms of smoothness to the touch and flexibility, superior to those provided by comparative composition B2 which comprises an identical content (7%) of fatty substances, but of a different nature.
