Patent ID: 7396803

Claim:
A composition comprising: (A) at least one water immiscible component selected from the group consisting of polyhydroxystearic acid, a polyhydroxyoleic acid, substantially fully esterified C 1 to C 9 alkyl esters of trimer acid, and mixtures thereof; (B) at least one water dispersible esterified trimer acid, wherein the water dispersible esterified trimer acid is the esterification product of: (1) an acid component comprising at least one member of the group consisting of trimer acid, hydrogenated trimer acid, and mixtures thereof; and (2) an alcohol component comprising: (i) at least one straight chain or branched saturated monohydric alcohol having from about 1 to about 24 carbon atoms; and (ii) at least one alkoxy poly(alkylene)glycol having one terminal hydroxyl group etherified with a C 1 to C 4 aliphatic monohydric alcohol and which is alkoxylated with from 2 to 25 moles of a C 2 to C 5 alkylene oxide; and (C) a co-emulsifier selected from the group consisting of straight chain or branched organic acids having between 8 and 20 carbon atoms and mixtures thereof, wherein the total amount of co-emulsifier is from 0 to about 50 weight percent of the total amount of (A), (B) and (C); wherein the weight ratio of the total of (A) to the combined total amount of (B) plus (C) is between about 3:1 and about 1:7 and the composition is capable of forming a synthetic system having a pH of greater than about 7.5 when added to water.
