Abstract
A detergent composition which is liquid at application temperature includes a hydrophobic surfactant system in combination with an aqueous component which is maintained in solution without gellation by an effective amount of N-methyl pyrrolidone. The N-methyl pyrrolidone allows the aqueous component preferably an aqueous solution of hydrogen peroxide to mix with the surfactant blend without causing the surfactant blend to gel. The N-methyl pyrrolidone can also be used to achieve similar results with other aqueous detergent components.
Claims12
A liquid detergent comprising a surfactant blend having an HLB of less than about 12 and from about 15% to about 77% by weight of an aqueous component in combination with an amount of N-methyl pyrrolidone effective to prevent gellation of the liquid detergent.
A low temperature liquid detergent composition comprising a liquid surfactant system having HLB less than about 11, an aqueous component and an amount of N-methyl pyrrolidone effective to maintain said aqueous component in said surfactant blend without gellation;
- an organic solvent and a (C1-C8)alkyl ether of alkylene(C2-C3)glycol.
A method of enhancing the stability of a detergent composition having a lipophyllic surfactant blend and an aqueous component comprising adding to said detergent composition N-methyl pyrrolidone in an amount effective to provide a stable non-gelled blend of said surfactant blend and said aqueous component.
