Abstract
Abstract A composition for forming a second composition to treat hair, and method of treating hair, are disclosed. The first composition is based upon guanidine hydroxide in an inert organic topically acceptable liquid medium which is essentially free of water and carbon dioxide. When the composition is ready for use, water is added thereto to form an aqueous composition which is suitable for use in treating hair to cause the hair to assume a desired configuration.

Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
60 words
A composition for treating hair when applied thereto, comprising a non-aqueous solution of guanidine hydroxide and from 0.5% to 25% by weight of said solution of an inert organic solvent for said guanidine hydroxide, the user adding a preselected amount of water to said solution before applying said composition to the hair, said composition having a pH greater than 11.8.
Claim 2
Dependent Claim
60 words
A composition for treating hair when applied thereto, comprising a non-aqueous solution of guanidine hydroxide and from 0.5% to 25% by weight of said solution of an inert organic solvent for said guanidine hydroxide, the user adding a preselected amount of water to said solution before applying said composition to the hair, said composition having a pH greater than 11.8.
Claim 3
Dependent Claim
14 words
A composition as claimed in claim 1 wherein said solvent contains a hydroxyl group.
Claim 4
Dependent Claim
20 words
A composition as claimed in claim 2 wherein said solvent is an alkanol having from 2 to 18 carbon atoms.
Claim 5
Dependent Claim
21 words

Dependent Claim
21 words
A composition as claimed in claim 1 wherein said solvent is an N-alkyl amide having from 3 to 12 carbon atoms.
Claim 9
Dependent Claim
53 words
A manufacture for use in treating hair comprising a container of a non-aqueous composition of guanidine hydroxide and an alcohol having from 2 to 18 carbon atoms to which an effective amount of water is added to form a preparation having a pH of at least 11.8 which is applied to the hair.
Claim 10
Dependent Claim
53 words
A manufacture for use in treating hair comprising a container of a non-aqueous composition of guanidine hydroxide and an alcohol having from 2 to 18 carbon atoms to which an effective amount of water is added to form a preparation having a pH of at least 11.8 which is applied to the hair.
Claim 11
Dependent Claim
12 words
