Independent Claim
204 words
A method of protecting skin and scalp from the irritating side effects of hair relaxers without interfering with the hair straightening action of hair relaxers, said method comprising applying to a user's scalp, prior to the application of the hair relaxer, a protection-effective amount of a composition comprising: a) about 10-85 weight percent parrafin; and b) about 15-90 weight percent of at least one ester, wherein the ester is of the formula: R.sub.1 --(COO)--[X- (COO)].sub.n --R.sub.2, wherein n is 0, 1, or 2; wherein R 1 is selected from the group consisting of C 1 -C 30 alkyl, C 1 -C 30 alkene, phenyl, benzyl, polyhydroxy C 1 -C 30 alkanols, C 1 -C 5 amino acid, C 1 -C 30 alkyl-amine, and C 1 -C 30 oxy-alcohol; wherein x is selected from the group consisting of a single bond, C 1 -C 30 alkyl, C 1 -C 30 alkene, C 1 -C 30 alkyl-oxy C 1 -C 30 alkyl, C 1 -C 30 alkyl-carboxy C 1 -C 30 alkyl, phenyl, and phenyl C 1 -C 30 alkyl; and wherein R 2 is defined the same as R 1 , and R 1 and R 2 may be the same or may be different.
Claim 2
Independent Claim
204 words
A method of protecting skin and scalp from the irritating side effects of hair relaxers without interfering with the hair straightening action of hair relaxers, said method comprising applying to a user's scalp, prior to the application of the hair relaxer, a protection-effective amount of a composition comprising: a) about 10-85 weight percent parrafin; and b) about 15-90 weight percent of at least one ester, wherein the ester is of the formula: R.sub.1 --(COO)--[X- (COO)].sub.n --R.sub.2, wherein n is 0, 1, or 2; wherein R 1 is selected from the group consisting of C 1 -C 30 alkyl, C 1 -C 30 alkene, phenyl, benzyl, polyhydroxy C 1 -C 30 alkanols, C 1 -C 5 amino acid, C 1 -C 30 alkyl-amine, and C 1 -C 30 oxy-alcohol; wherein x is selected from the group consisting of a single bond, C 1 -C 30 alkyl, C 1 -C 30 alkene, C 1 -C 30 alkyl-oxy C 1 -C 30 alkyl, C 1 -C 30 alkyl-carboxy C 1 -C 30 alkyl, phenyl, and phenyl C 1 -C 30 alkyl; and wherein R 2 is defined the same as R 1 , and R 1 and R 2 may be the same or may be different.
Claim 3
Independent Claim
190 words
A method of relaxing hair without irritating the skin and scalp which comprises applying a protection-effective amount of a composition comprising: a) about 10-85 weight percent parrafin; and b) about 15-90 weight percent of at least one ester, wherein the ester is of the formula: R.sub.1 --(COO)--[X-(COO)].sub.n --R.sub.2, wherein n is 0, 1, or 2; wherein R 1 is selected from the group consisting of C 1 -C 30 alkyl, C 1 -C 30 alkene, phenyl, benzyl, polyhydroxy C 1 -C 30 alkanols, C 1 -C 5 amino acid, C 1 -C 30 alkyl-amine, and C 1 -C 30 oxy-alcohol; wherein x is selected from the group consisting of a single bond, C 1 -C 30 alkyl, C 1 -C 30 alkene, C 1 -C 30 alkyl-oxy C 1 -C 30 alkyl, C 1 -C 30 alkyl-carboxy C 1 -C 30 alkyl, phenyl, and phenyl C 1 -C 30 alkyl; and wherein R 2 is defined the same as R 1 , and R 1 and R 2 may be the same or may be different, to a user's scalp, and then applying a hair relaxer to the user's hair.
Claim 4
