Claims20
A composition for treating live human hair comprising water, an organic solvent or mixtures thereof which includes, as an ingredient thereof, a hydrophobic-lipophobic compound of anionic, cationic, nonionic or amphoteric character corresponding to the formula
- CF 3--(CF.sub.2).sub.x --(CH.sub.2).sub.y --Z
- where Z is a member selected from the group consisting of a water-solubilizing groups and an oil-solubilizing group, x is an integer from 2 to 17, and y is an integer from 0 to 4, said compound being present in proportions, based on the weight of the composition, in the range of about 0.05% to not in substantial excess of the solubility or ready dispersibility of said compound in the composition and not in excess of 10%, said composition also containing, as an additional ingredient, a combing aid selected from the group consisting of cationic compounds, silicones and proteins.
A method of retarding the flow of sebum along the hair shafts of hair on the human head which comprises contacting said hair with a solution containing from about 0.05% to 10% by weight of a hydrophobic-lipophobic compound of anionic, cationic, nonionic or amphoteric character corresponding to the formula
- CF.sub.3 --(CF.sub.2).sub.x --(CH.sub.2).sub.y --Z
- where Z is a member selected from the group consisting of a water-solubilizing groups and an oil-solubilizing group, x is an integer from 2 to 17, and y is an integer from 0 to 4.
