At least one organic silicon atom - containing compound, a cosmetic composition containing at least one cationic surfactant and at least one organic acid, and cosmetic treatment methods of using said compositions
Cosmetic composition comprises at least one organic silicon compound comprising silanes containing a silicon atom and siloxanes comprising two or three silicon atoms, where the organic silicon compounds further comprises at least one basic chemical functions and one or more hydroxyl groups or hydrolyzable group per molecule, and the silanes are organosilane compound (I), one or more cationic surfactants, and one or more organic acids, in a medium. Cosmetic composition comprises at least one organic silicon compound comprising silanes containing a silicon atom and siloxanes comprising two or three silicon atoms, where the organic silicon compounds further comprises at least one basic chemical functions and one or more hydroxyl groups or hydrolysable group per molecule, and the silanes are organosilane compound of formula ((R1)(R2)N-R3-Si(R4)(R5)(R6)) (I), one or more cationic surfactants, and one or more organic acids, in a medium. R4 : halo, OR1a or R11a group； R5 : halo, OR2a or R22a group； R6 : halo, OR3a or R33a group； and R1, R2, R3, R1a, R2a, R3a, R11a, R22a, R33a : optionally saturated, optionally linear hydrocarbon group, optionally bearing additional chemical groups. Provided that: at least two of R1, R2, R1a, R2a and R3a groups are H； at least two of R4, R5 and R6 groups are OR1a, OR2a and OR3a； and at least two of R1a, R2a and R3a groups are different from hydrogen. An independent claim is included for a process for cosmetic treatment of keratin fibers comprising applying the composition on the fibers, and rinsing after an optional exposure time.
