Abstract
Abstract This invention relates to the use of alpha olefin/maleic anhydride terpolymers in conjunction with anionic surfactants, such as ammonium lauryl sulfate and ammonium lauryl ether sulfate, in hair, skin and other cleaning compositions. The use of alpha olefin/maleic anhydride terpolymers in such cleaning compositions reduces the irritation potential of anionic surfactants without decreasing the foaming and cleaning characteristics of such compositions.

Claims Analysis
Total Claims: 16
Claim 1
Independent Claim
126 words
A cleaning composition comprising: (a) at least one anionic surfactant having foaming and cleansing properties and a tendency to irritate sensitive tissues in an amount of 0.15 to 25% by weight of the composition; (b) at least one alpha maleic anhydride terpolymer containing about 49-60 mole percent maleic anhydride, about 10-40 mole percent of at least one lower 1-alkene having from 4-16 carbon atoms, and about 40-10 mole percent of at least one higher 1-alkene having at least 18 carbon atoms in an amount of 0.1 to 18% by weight of the composition, said ingredient in amount so as not to reduce the foaming and cleaning properties of said composition; and (c) an aqueous vehicle in an amount up to 99% by weight of the composition.
Claim 2
Dependent Claim
126 words
A cleaning composition comprising: (a) at least one anionic surfactant having foaming and cleansing properties and a tendency to irritate sensitive tissues in an amount of 0.15 to 25% by weight of the composition; (b) at least one alpha maleic anhydride terpolymer containing about 49-60 mole percent maleic anhydride, about 10-40 mole percent of at least one lower 1-alkene having from 4-16 carbon atoms, and about 40-10 mole percent of at least one higher 1-alkene having at least 18 carbon atoms in an amount of 0.1 to 18% by weight of the composition, said ingredient in amount so as not to reduce the foaming and cleaning properties of said composition; and (c) an aqueous vehicle in an amount up to 99% by weight of the composition.
