A process for preparing an opaque composition using ethylene glycol distearate including the steps of providing a starting composition including A) from 0.5 parts by weight to 15 parts by weight of at least one surfactant, B) from 0.5 parts by weight to 15 parts by weight of at least one emulsifier, C) from 10 parts by weight to 30 parts by weight ethylene glycol distearate, and D) from 20 parts by weight to 85 parts by weight water; b) stirring the starting composition at a temperature in a range from 60° C. to 100° C.; and c) cooling to a temperature in a range from 5° C. to 55° C. to obtain the opaque composition.

Opaque composition comprising ethylene glycol distearate

The invention relates to a process for preparing an opaque composition using ethylene glycol distearate.

The invention relates to compositions comprising certain sorbitan carboxylic esters and glycerol carboxylic esters in particular amounts.

Compositions comprising sorbitan carboxylic esters and glycerol carboxylic esters

The present invention relates to a method in which an amino acid is reacted with an acyl group donor to obtain an N-acylamino acid in the presence of an amine.

Method for producing surfactants

The invention provides polyglycerol alkoxylate esters and for the preparation and use thereof.

Polyglycerol alkoxylate esters and preparation and use thereof

A subject-matter of the invention are betaines with a special fatty acid chain distribution, for example based on palm kernel oil, the palm kernel oil comprising an enhanced content of unsaturated Cfatty acids.

Betaines with special fatty acid chain distribution

The invention provides polyglycerol partial esters based on mono- and dicarboxylic acids and their use as solubilizers, particularly in cosmetics, for example for perfume oils and essential oils in aqueous systems.

Cross-linked polyglycerol esters

Polyglycerol partial esters of a specific composition which are capable of solubilizing very hydrophobic, oil-soluble substances in aqueous solution are provided. The preparation and use of these polyglycol ether-free solubilizers in cosmetic formulations are also disclosed.

Polyglycerol partial esters, preparation and use thereof

The invention relates to polyglycol ether-free, polyglycerol partial ester-based sulphosuccinates, the preparation thereof, and the use of these in cosmetic formulations and also in cleaning compositions in the industrial and domestic sector and formulations comprising these sulphosuccinates.

Polyglycol ether-free sulphosuccinates based on polyglycerol partial esters and use thereof
