Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
122 words
A method of conditioning the hair which comprises applying to the hair a conditioningly effective amount of a compound or mixture of compounds having the formula: ##STR3## where Z is selected from the group consisting of X and --N(CH 3 ) 2 , wherein X is a halogen having an atomic weight greater than 34, where X - is the anionic form of X, there being one such anionic halogen for each cationic nitrogen, and wherein n is an integer of from 2 to 20, said compound or mixture of compounds being formed by the reaction of equimolar proportions of 1,3-bis-dimethylamino-2-propanol and 1,3-dichloro-2-propanol, the reaction being affected at a temperature of about 40° to about 90° for about 2 to 12 hours.
