Compositions and process for treating hair

Claim 1

A composition for treating the hair to improve the manageability, softness and appearance which comprises (1) from 0.025 to 5% by weight of an organosilicon compound selected from (a) silanes represented by the general formula Q.sub.3 SiRN.sup.+ (R').sub.3 X.sup.- wherein each Q represents an alkyl group having from 1 to 4 carbon atoms, a hydroxyl group, or an alkoxy group or alkoxy-alkoxy group having less than 12 carbon atoms, R represents a divalent organic group having from 3 to 10 carbon atoms selected from the group consisting of aliphatic hydrocarbon radicals, aliphatic hydrocarbon radicals containing ether linkages, hydroxyl-substituted aliphatic hydrocarbon radicals and hydroxyl-substituted aliphatic hydrocarbon radicals containing ether linkages, each R' represents a monovalent hydrocarbon group having from 1 to 18 carbon atoms and X represents a halogen atom, and (b) polydiorganosiloxanes having in the molecule at least one silicon-bonded group represented by the general formula --RN.sup.+ (R').sub.3 X.sup.- wherein R, R' and X are as hereinabove defined, at least 40 percent of the total silicon-bonded substituents being methyl groups and any remaining substituents being selected from monovalent hydrocarbon groups having from 2 to 8 carbon atoms, hydroxyl groups and alkoxy and alkoxyalkoxy groups having less than 12 carbon atoms, (2) from 0.025 to 5% by weight of a polydiorganosiloxane having in the formula at least one group represented by the general formula .tbd.SiR"NHR"' wherein R" represents an alkylene group having from 3 to 8 inclusive carbon atoms and R"' represents a hydrogen atom, an alkyl group having from 1 to 4 inclusive carbon atoms or an aliphatic hydrocarbon group attached to the nitrogen atom through a carbon to nitrogen bond and containing at least one group selected from --NH-- and --NHZ groups wherein Z represents a hydrogen atom or an alkyl group having from 1 to 4 carbon atoms, at least 50 percent of the total silicon-bonded substituents being methyl groups and any remaining substituents being selected from monovalent hydrocarbon groups having from 2 to 8 carbon atoms, hydroxyl groups and alkoxy and alkoxyalkoxy groups having less than 12 carbon atoms, (3) from 0.01 to 30% by weight of at least one surfactant and (4) from 60 to 99.94% by weight of water.
