Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
156 words
A method for enhancing the drying of hair when water or an aqueous composition is applied, comprising applying thereto an aqueous solution containing from about 0.05 to 5% of a cationic or amphoteric compound having the formula: (C.sub.n F.sub.2n +.sub.1) -- R--Q wherein n is an integer from 4 to 18, R is selected from the group consisting of (CH 2 ) x , (CH 2 ) y --O--(CH 2 ) z , (CH 2 ) y --S--(CH 2 ) z , ##STR6## wherein x is an integer from 1 to 6, the terminal (CH 2 ) y group is attached to the (C n F 2 + 1 ) portion of the molecule, the terminal (CH 2 ) z group is attached to the Q portion of the molecule, y is an integer from 0 to 3, z is an integer from 1 to 3 and Q is selected from the group consisting of: ##STR7##
Claim 2
Independent Claim
156 words
A method for enhancing the drying of hair when water or an aqueous composition is applied, comprising applying thereto an aqueous solution containing from about 0.05 to 5% of a cationic or amphoteric compound having the formula: (C.sub.n F.sub.2n +.sub.1) -- R--Q wherein n is an integer from 4 to 18, R is selected from the group consisting of (CH 2 ) x , (CH 2 ) y --O--(CH 2 ) z , (CH 2 ) y --S--(CH 2 ) z , ##STR6## wherein x is an integer from 1 to 6, the terminal (CH 2 ) y group is attached to the (C n F 2 + 1 ) portion of the molecule, the terminal (CH 2 ) z group is attached to the Q portion of the molecule, y is an integer from 0 to 3, z is an integer from 1 to 3 and Q is selected from the group consisting of: ##STR7##
Claim 3
Dependent Claim
14 words
The method according to claim 1 wherein the aqueous solution also contains shampoo detergents.
Claim 4
Dependent Claim
18 words
The method according to claim 1 wherein the treatment of said hair is followed by a water rinse.
Claim 5
Independent Claim
212 words
A method of treating hair to enhance drying which comprises the steps of applying thereto a composition consisting essentially of an aqueous solution of from about 10 to 30% of a lower alcohol selected from the group consisting of methanol, ethanol n-propanol and isopropanol, from about 0.05 to 1% of a cationic or amphoteric compound of the formula: (C.sub.n F.sub.2 +.sub.1) -- R--Q wherein n is an integer from 4 to 18, R is selected from the group consisting of (CH 2 ) x , (CH 2 ) y --O--(CH 2 ) z , (CH 2 ) y --S--(CH 2 ), ##STR8## wherein x is an integer from 1 to 6, the terminal (CH 2 ) z group is attached to the (C n F 2n + 1 ) portion of the molecule, the terminal (CH 2 ) z group is attached to the Q portion of the molecule, y is an integer from 0 to 3, z is an integer from 1 to 3, and Q is selected from the group consisting of: ##STR9## wherein R 1 , R 2 , and R 3 are alkyl groups containing from 1 to 4 carbon atoms, and 0-5% of a cationic conditioner, and therefafter rinsing said aqueous solution from the hair with water.
