Abstract
Description
Composition comprising an amino acid, a hydroxylated (poly)carboxylic acid, a silicone and a non-silicone solid fatty substance with a specific non-silicone solid fatty substance / silicone ratio
[0001] The present invention relates to a cosmetic composition, notably a hair composition, comprising one or more compounds of amino acid type, one or more hydroxycarboxylic acids, one or more silicones and one or more non-silicone solid fatty substances with a non-silicone solid fatty substance(s) / silicone(s) weight ratio of less than or equal to 10. The invention also relates to a cosmetic treatment process using said composition.
[0002] Hair may be damaged or embrittled by the action of external atmospheric agents such as the light and weathering, or by mechanical or chemical treatments such as brushing, combing, dyeing, bleaching, permanent-waving and / or relaxing. In particular, dyeing or bleaching hair compositions can sometimes be responsible for degrading the quality of the hair fibres, as the proteins making up the hair can be denatured. This degradation of the fibre quality may lead to substantial breakage during combing of the hair, notably when these compositions are applied to sensitized hair, and also to a degradation of the cosmetic properties of the hair, most particularly the sheen. To overcome these drawbacks, it is common practice to make use of hair treatments which can condition the hair. These haircare compositions may be conditioning shampoos or hair conditioners, which may be in the form of hair gels or lotions or more or less thick creams. However, it is still possible to improve the performance afforded by such compositions, notably in terms of providing strength (denser, stiffer hair), and also in terms of cosmetic properties such as disentangling, a smooth feel, suppleness, softness, manageability, hair strand separation and sheen.
[0003] The composition which is the subject of the present invention, and the use thereof, allow this aim to be achieved.
[0004] One subject of the present invention is thus a cosmetic composition, notably a hair composition, comprising:
[0005] - one or more compounds of amino acid type, present in a total content of at least 0.5% by weight, relative to the total weight of the composition,
[0006] - one or more hydroxylated (poly)carboxylic acids, comprising 2 to 8 carbon atoms, and / or salts thereof, present in a total content of at least 0.5% by weight, relative to the total weight of the composition,
[0007] - one or more silicones,
[0008] - one or more non-silicone solid fatty substances,
[0009] it being understood that the weight ratio between the total content of non-silicone solid fatty substance(s) and the total content of silicone(s) is less than or equal to 10.
[0010] The composition according to the invention was found to improve the hair's resistance to breakage, to strengthen the hair and also to significantly limit its reduction or loss of sheen, or even to improve its sheen.
[0011] The composition according to the invention affords the hair good cosmetic properties, notably in terms of transformation of the hair, disentangling, a smooth feel, suppleness, softness, manageability and hair strand separation, and also excellent performance in terms of sheen, and does so while affording strength, body and a volumizing effect to the head of hair.
[0012] The composition according to the invention finds a very particular application in the cosmetic treatment, notably the conditioning, of keratin fibres that have become sensitized, embrittled and / or damaged, notably following physical treatments (repeated brushing) and / or chemical treatments, for example dyeing, bleaching, permanent waving and / or relaxing.
[0013] In the text hereinbelow, unless otherwise indicated, the limits of a range of values are included in that range, notably in the expressions “between” and “ranging from ... to ...”.
[0014] Moreover, the expression “at least one” used in the present description is equivalent to the expression “one or more”, and may be replaced therewith.
[0015] For the purposes of the present invention, the term “the hair” means head hair. This term does not correspond to bodily hairs, the eyebrows or the eyelashes.
[0016] “Transformation” or “transformation on application” is understood as meaning the softening of the keratin fibre on contact with a composition. More particularly, the composition according to the invention is applied to wet hair. The property of transformation is therefore evaluated on wet hair.Compounds of amino acid type
[0017] The composition according to the present invention comprises at least 0.5% by weight of one or more compounds of amino acid type.
[0018] For the purposes of the present invention, the term “compound of amino acid type” means an organic compound comprising one or more carboxylic acid and / or sulfonic acid functions and one or more amine functions, it being possible for the amine function(s) to be endocyclic, optionally in salt form.
[0019] Preferably, the compound(s) of amino acid type are chosen from compounds of amino acid type comprising only one or more carboxylic acid functions (thus not comprising any sulfonic acid functions) and / or salts thereof. Said compounds are also called compounds of aminocarboxylic acid type and are particularly preferred.
[0020] Preferably, the composition according to the present invention comprises one or more compounds of amino acid type chosen from the compounds corresponding to formula (A) below and / or salts thereof.

The number-average size of the silicone particles in the emulsion generally ranges from 3 nm to 500 nm.

In general, the size of the wax crystals is such that the crystals diffract and / or scatter light, giving the composition that comprises them a more or less opaque cloudy appearance. By bringing the wax to its melting point, it is possible to make it miscible with oils and to form a microscopically homogeneous mixture, but on returning the temperature of the mixture to room temperature, recrystallization of the wax, which is microscopically and macroscopically detectable (opalescence), is obtained.
[0268] In particular, the waxes that are suitable for use in the invention may be chosen from waxes of animal, plant or mineral origin, non-silicone synthetic waxes, and mixtures thereof.
