Abstract
The present application provides for novel anhydride substituted starches and their use in personal and home care products. The natural based starches disclosed are useful for the replacement of chemical surfactants in personal and home care products. The starches demonstrate the unique ability to create and maintain desired properties in these products. The anhydride substituted starches are particularly useful in replicating the foaming properties of standard chemical surfactants.
Claims19
An anhydride modified dextrin wherein the anhydride modified dextrin has (i) an anhydride modification comprising a degree of substitution between 0.1 and 0.8 and (ii) was prepared from a base dextrin having an average molecular weight of between 15,000 and 200,000 g/mol, and wherein the anhydride modification includes a hydrophobic moiety including 8 to 22 carbon atoms such that the anhydride modified dextrin has a surfactant functionality and in an effective amount to build foam.
A personal care or home care formulation comprising an anhydride modified dextrin functioning in the formulation as a surfactant, wherein the anhydride modified dextrin has (i) an anhydride modification comprising a degree of substitution between 0.1 and 0.8 and (ii) was prepared from a base dextrin having an average molecular weight of between 15,000 and 200,000 g/mol, and wherein the anhydride modification includes a hydrophobic moiety having 8 to 22 carbon atoms and in an effective amount to build foam.
