Abstract: Agent for treating keratin-containing fibers, particularly, human hair, containing in a cosmetically-acceptable vehicle: (a) at least one amphiphilic, cationic polymer having at least one formula (I) structural unit, at least one formula (II) structural unit, at least one formula (III) structural, and at least one formula (IV) structural unit, where R1 and R4 independently=H or methyl; X1 and X2 independently=O or NH, A1 and A2 independently=ethan-1,2-diyl, propan-1,3-diyl or butan-1,4-diyl, R2, R3, R5 and R6 independently=(C1-C4) alkyl, R7=(C8-C30) alkyl and (b) at least one polymer having one or more silicon-containing sidechains and one or more anionic groups, use of the agent for temporary shaping of hair and for haircare, particularly in the form of a hair cream or hair gel.

Abstract: An agent for the temporary deformation of keratinic fibers comprises, in a cosmetically acceptable carrier, a) at least one copolymer A formed from: at least one monomer A1 selected from acrylic acid, methacrylic acid, acrylic acid alkyl esters, and methacrylic acid alkyl esters; at least one monomer A2 selected from acrylic acid hydroxyalkyl esters and methacrylic acid hydroxyalkyl esters; and at least one monomer A3 selected from succinic acid monoalkyl esters and succinic acid dialkyl esters; and at least one film-forming and setting amphoteric polymer. A method for using the agent for the temporary deformation of hair, and an aerosol hair spray containing the agent and at least one propellant also are provided.

Abstract: A cleaning agent for keratinic fibers which is essentially free of anionic surfactants is comprised, based on the weight of the cleaning agent, of from 1 to 50 wt. % of one or more cationic surfactants of wherein R is an alkyl group having from 8 to 18 carbon atoms; each of R1, R2, and R3 is independently a C1-C3-alkyl group and X? is a halogen or methosulfate. The cleaning agents can be used for conditioning and color protection of hair as well as the reduction and prevention of damage to hair.
