Abstract
Disclosed herein are novel mixtures of scattered-branched chain fatty acids and derivatives of scattered-branched chain fatty acids. Further disclosed are uses of these mixtures in cleaning compositions (e.g., dishcare, laundry, hard surface cleaners) and/or personal care compositions (e.g., skin cleansers, shampoo, hair conditioners).
Claims13
A composition comprising a mixture of at least two compounds of Formula I:
- wherein each R1 independently is H or CH3, with the proviso that 1, 2, or 3 R1 is CH3;
- m is 1 or 2;
- n is 3, 4, 5, 6, 7, 8, or 9;
- p is 1, 2, 3, 4, 5, 6, 7, or 8;
- and,
- Y is CH2 or absent, with the proviso that when:
- (a) Y is CH2, Z is selected from the group consisting of hydroxyl, a sulfate, or a sulfonate;
- and,
- (b) Y is absent, Z is a carboxylic acid;
- wherein at least one compound of Formula I is selected from the group consisting of:
- wherein:
- r is 2, 3, 4, 5, 6, 7, or 8;
- s is 1, 2, 3, 4, 5, 6, or 7;
- t is 0, 1, 2, 3, 4, 5, or 6;
- u is 0, 1, 2, 3, 4, or 5;
- v is 0, 1, 2, 3, or 4;
- and,
- w is 0, 1, 2, or 3;
- wherein the mixture is present in an amount of at least about 80 wt. %, based on the total weight of the composition;
- wherein the mixture comprises no more than about 5 wt. % of compounds that have a longest linear carbon chain of 9 carbon atoms or fewer, and less than about 50 wt. % of compounds of Formula I that contain branching on a carbon atom that is within 40% of the nonfunctionalized terminus of the longest carbon chain, based on the total weight of the mixture, and;
- wherein the mixture further comprises at least one compound of Formula III:
- wherein q is 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, or 20;
- p is 1 or 2;
- Y is CH2 or absent, with the proviso that when:
- (a) Y is CH2, Z is selected from the group consisting of hydroxyl, a sulfate, or a sulfonate;
- and,
- (b) Y is absent, Z is a carboxylic acid;
- wherein the compound of Formula III is present in an amount of about 1 wt. % to about 99 wt. %, based on the total weight of the mixture.
A composition comprising a mixture of at least two compounds of Formula I:
- wherein each R1 independently is H or CH3, with the proviso that 1, 2, or 3 R1 is CH3;
- m is 1 or 2;
- n is 3, 4, 5, 6, 7, 8, or 9;
- p is 1, 2, 3, 4, 5, 6, 7, or 8;
- and,
- Y is CH2 or absent, with the proviso that when:
- (a) Y is CH2, Z is selected from the group consisting of hydroxyl, a sulfate, or a sulfonate;
- and,
- (b) Y is absent, Z is a carboxylic acid;
- wherein at least one compound of Formula I is selected from the group consisting of
- wherein the mixture is present in an amount of at least about 80 wt. %, based on the total weight of the composition;
- wherein the mixture comprises no more than about 5 wt. % of compounds that have a longest linear carbon chain of 9 carbon atoms or fewer, and less than about 50 wt. % of compounds of Formula I that contain branching on a carbon atom that is within 40% of the nonfunctionalized terminus of the longest carbon chain, based on the total weight of the mixture, and;
- wherein the mixture further comprises at least one compound of Formula III:
- wherein q is 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, or 20;
- p is 1 or 2;
- Y is CH2 or absent, with the proviso that when:
- (a) Y is CH2, Z is selected from the group consisting of hydroxyl, a sulfate, or a sulfonate;
- and,
- (b) Y is absent, Z is a carboxylic acid;
- wherein the compound of Formula III is present in an amount of about 1 wt. % to about 99 wt. %, based on the total weight of the mixture.
The composition of claim 3, wherein the cleaning composition comprises about 0.1 wt. % to about 80 wt. % the composition according to claim 5.
