摘要:
An emulsifier mixture for use in a wax-based opacifier composition is comprised of: (a) an alkyl and/or alkenyl oligoglycoside; (b) a fatty acid partial glyceride and optionally (c) at least one amphoteric surfactant, with the proviso that the ratio by weight of (a) and optionally (c) to (b) is between 6:1 and 3:1 and wherein the composition is free from anionic surfactants.
