Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
68 words
A method of simultaneously obtaining pearlescence and conditioning of hair which comprises applying to the hair an aqueous composition consisting essentially of a conditioning agent and water, said conditioning agent being alkyl dimethylamine oxide wherein the alkyl is substantially straight chain and has 16 to 22 carbon atoms and said conditioning agent being applied in an effective amount sufficient to obtain both pearlescence and conditioning of the hair.
Claim 2
Independent Claim
68 words
A method of simultaneously obtaining pearlescence and conditioning of hair which comprises applying to the hair an aqueous composition consisting essentially of a conditioning agent and water, said conditioning agent being alkyl dimethylamine oxide wherein the alkyl is substantially straight chain and has 16 to 22 carbon atoms and said conditioning agent being applied in an effective amount sufficient to obtain both pearlescence and conditioning of the hair.
Claim 3
Dependent Claim
22 words
The method of claim 1 wherein the ratio of conditioning agent to water is between about 1:8 and 1:48 parts by weight.
Claim 4
Dependent Claim
20 words
The method of claim 1 wherein the hair is first washed and rinsed prior to application of the aqueous composition.
Claim 5
Dependent Claim
34 words
The method of claim 1 wherein the aqueous composition is retained on the hair for from about 1 to 2 minutes, followed by an aqueous rinsing sufficient to remove excess composition from the hair.
