Problems solved by technology

Known opacifiers are mainly based on copolymers based on acrylic or methacrylic acid and styrene and are not biodegradable.
In addition, formulations containing sugar surfactants show relatively poor stability in storage at elevated temperature, particularly in regard to color quality and stability.

The wax, the fatty acid polyol esters (c), partial glycerides (b) and the amphoteric surfactants (a) were mixed in various ratios by weight and the particle fineness was determined by determining the particle size distribution in μm and the mean particle diameter in μm by laser diffraction (Mastersizer 2000; see product specification of MALVERN INSTRUMENTS GmbH, Herrenberg, Germany). Viscosity was measured by the Brookfield method (23° C., spindle 5, 10 r.p.m., mPas). The results are set out in Table 1.

Abstract

The invention relates to wax-based opacifier preparations containing (a) at least one amphoteric surfactant, (b) at least one fatty acid partial glyceride, (c) at least one fatty acid polyglycol ester and optionally (d) a polyol, with the proviso that the ratio by weight of (a) to (b) is between 10:1 and 4:1 and the ratio by weight of (b) to (c) is between 1:1 and 5:1 and the preparations are free from anionic surfactants.

Description

FIELD OF THE INVENTION This invention relates to opacifiers containing waxes, amphoteric surfactants, fatty acid partial glycerides, fatty acid polyglycol esters and optionally polyols in a certain ratio by weight, but no anionic surfactants, and to their use as opacifiers. PRIOR ART In the formulation of a number of surface-active household products, such as dishwashing detergents for example, or cosmetic preparations, such as hair shampoos for example, particular importance is attributed to the products being clear and not clouding, even in storage. In other cases, cloudy products with a shimmering effect known as pearlescence are required for the same purpose. A third group of products is made with a non-shimmering opaque whiteness using so-called opacifiers. Opacifiers are fine-particle dispersions of polymers or solids which, apart from water and / or a polyol (for example glycerol), largely contain only a wax and a suitable emulsifier. Known opacifiers are mainly based on cop...
