Abstract
Abstract A hair care composition in the form of a gel-like, highly viscous microemulsion, especially suitable for damaged hair, containing: a) from 5 to 20 percent by weight of a nonionic surfactants with an HLB-value of from 5 to 12 or mixtures of the nonionic surfactants, the mixtures having HLB-values of from 6 to 10; b) from 5 to 20 percent by weight of at least one oil; c) from 0.5 to 10 percent by weight of at least one cationic surfactant; and d) from 50 to 89.5 percent by weight water, and not containing a nonionic surfactant with an HLB-value of greater than 12.
