Abstract
The invention concerns pearly luster concentrates in the form of an aqueous dispersion having between 10 and 40 wt % pearly luster-forming components and between 15 and 55 wt % emulsifiers. The concentrates contain as emulsifiers alkylpolyglycosides of general formula (I), RO—(Z)x, in which R stands for a C6 to C22 alkyl group, Z stands for a mono or oligosaccharide, x is a number from 1.1 to 5, or their addition products with 1 to 10 molecules ethylene oxide and/or propylene oxide. The concentrates are characterized by a Newtonian flow behaviour when they are free of emulsifiers with —COO—and —OSO3 —groups, such that these concentrates are considerably easier to handle.
Claims23
A pearlescent concentrate having newtonian viscosity, consisting essentially of an aqueous dispersion of 10% to 40% by weight of a pearlescing component and 15% to 55% by weight of an alkyl polyglycoside of the formula (I):
- RO—(Z)x (I)
- wherein R is C6 to C22 alkyl, Z is a mono- or oligosaccharide, and x is a number of 1.1 to 5, and wherein the concentrate is free from emulsifiers containing —COO—and —OSO3 —groups.
