Abstract
The hair care compositions contain a combination of from 0.01 to 10 percent by weight of at least one terminally functionalized diquaternary silicone compound of formula II:R1R2R3N+—A—SiR7R8—(O—SiR9R10)n—O—SiR11R12—A—N+R4R5R62X1−  (II),wherein R1 and R4, independently of each other, each represent an alkyl group with at least eight carbon atoms, and R2 R3 and R15 to R4, independently of each other, each represent a methyl group. A represents —(CH2)3—O—CH2—CH(OH)—CH2—, n is a number from 10 to 120 and X1− is an anion; and from 0.01 to 10 percent by weight of at least one quaternized amine compound of formula lb:R1—NH—(CH2)m—N+R2R3R4 X−  (lb),wherein R1 represents a C8- to C24-acyl group; wherein R2, R3 and R4 represent, independently of each other, C1- to C6-alkyl group; X− is an anion and m is 2 to 5. These compositions optionally contain at least one ester of an alphatic carboxylic acid with a primary or secondary alcohol.
