Abstract: The present invention relates to a cosmetic composition comprising: a) at least one anionic surfactant; b) at least one amphoteric or zwitterionic surfactant; c) at least one oil-in-water emulsion having a particle size D50 of less than 350 nm, the size being expressed on a volume basis, and comprising: —a silicone mixture comprising (i) one or more polydialkylsiloxanes bearing trialkylsilyl end groups, having a viscosity at 25° C. ranging from 40000 to 100000 mPa·s and (ii) one or more amino silicones having a viscosity at 25° C. ranging from 1000 to 15 000 mPa·s and an amine number ranging from 2 to 10 mg of KOH per gram of amino silicone; —a surfactant mixture comprising one or more nonionic surfactants, said mixture having an HLB ranging from 10 to 16; and—water; and d) at least 0.01% by weight, relative to the total weight of the composition, of one or more agents chosen from fatty amines, fatty acids, fatty alcohols and mixtures thereof.

Abstract: The present disclosure relates to methods for treating hair, which are particularly useful for repairing, strengthening, and protecting hair from damage. The methods include applying to the hair each of the following components, together, separately, or in any combination thereof, in one or more hair-treatment compositions:



(a) at least one amino acid or amino sulfonic acid, and/or a salt thereof, which is present in at least one of the one or more hair-treatment compositions in an amount of at least 0.5 wt. %;
(b) at least one non-polymeric mono, di, or tricarboxylic acid, and/or a salt thereof, which is present in at least one of the one or more hair-treatment compositions in an amount of at least 0.5 wt. %; and
(c) at least one non-taurate surfactant, which is present in at least one of the one or more hair-treatment compositions.




Hair treated with the methods exhibit desirable cosmetic properties such as smoothness, gloss, improved combability, and improved strength and elasticity.

Abstract: The present disclosure relates to hair-treatment compositions, which are particularly useful for repairing, strengthening, and protecting hair from damage. The hair-treatment composition include at least 0.5 wt. % of at least one amino acid or amino sulfonic acid, and/or a salt thereof, and optionally, at least 0.5 wt. % of at least one non-polymeric mono, di, or tricarboxylic acid, and/or a salt thereof. Additional components such as surfactants and water may also be included. The unique components of the hair-treatment compositions restructure the hair fibers and result in the hair exhibiting improved properties such as increased hair fiber strength, better discipline, and more curl definition.
