PEARLY LUSTRE CONCENTRATE WITH NEWTONIAN VISCOSITY

摘要

The invention concerns pearly lustre concentrates in the form of an aqueous dispersion having between 10 and 40 wt % pearly lustre-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.
