The invention relates to a polyglycerol partial ester obtainable by esterification of a polyglycerol with a carboxylic acid mixture comprising at least one polyhydroxycarboxylic acid of a hydroxycarboxylic acid having 8 to 32 carbon atoms, at least one short-chain dicarboxylic acid having 2 to 16, preferably 6 to 14, particularly preferably 8 to 12, carbon atoms, at least one long-chain dicarboxylic acid having 24 to 44, preferably 30 to 40, particularly preferably 34 to 38, carbon atoms, and at least one fatty acid selected from linear, unsaturated and branched, saturated fatty acids having 14 to 24 carbon atoms, to a method for preparing polyglycerol partial esters, and to the use of corresponding polyglycerol partial esters as W/O emulsifier.

Cross-linked polyglycerol esters

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.

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.

Polyglycerol partial esters of polyricinoleic acid and polyfunctional carboxylic acids and the use thereof for producing emulsions and dispersions

The present invention relates to polyglycerol partial esters of polyhydroxystearic acid and polyfunctional carboxylic acids which are obtainable by esterification of a polyglycerol mixture with polyhydroxystearic acid where N=1 to 10, preferably 2 to 8, in particular 3 to 5 units and dimer fatty acids which have been obtained by catalytic dimerization of unsaturated fatty acids having 12 to 22 C atoms and have an average functionality of 2 to 3, and/or with aliphatic, linear or branched dicarboxylic acids having a chain length of 2 to 16 C atoms and additionally saturated or unsaturated, linear or branched fatty acids having 6 to 22 C atoms, preferably 12 to 18 C atoms, the degree of esterification of the polyglycerol mixture being between 20 and 75%, preferably 40 to 70%.

Emulsifier for highly liquid W/O emulsion based on partly crosslinked polyglycerol esters of polyhydroxystearic acid

The present invention provides a defined alkylpolyglucoside having a degree of oligomerization of at least 1.7 to 3 and an alkyl radical comprising 8 carbon atoms, and mixtures of this alkylpolyglucoside with further alkylpolyglucosides, as cleaner concentrate. The present invention also relates to compositions which include the defined alkylpolyglucoside and a concentrated alkali metal hydroxide solution as well as a method of using the composition as a cleaner.
