Non-aqueous, nonionic heavy duty laundry detergent with improved stability.

摘要

A non-aqueous liquid heavy duty laundry detergent composition in the form of a suspension of builder salt in liquid nonionic surfactant is stabilized against phase separation by the incorporation of gas bubbles having an average particle size diameter of 10 to 100 microns. The gas bubbles are incorporated in an amount to equalize the densities of the continuous liquid phase and the dispersed phase. The gas bubbles are stabilized by incorporation of a stabilizer having the formula <CHEM> wherein R is a hydrocarbon group of about 5 to 21 carbon atoms, Q is a hydrogen atom, a Group IA metal, a Group IIA metal, a group having the formula -CH2-CH(R<1>)-CH2(R<2>), or a mixture thereof, wherein R<1> and R<2> are, independently, -OH or R-C(O)O- (R being as defined above); and a is 1 or 2, with the proviso that a=2 only when Q is a Group IIA metal.
