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 relates to a dispersion containing at least one rhamnolipid derivative and also to the use of the rhamnolipid derivatives as emulsifier or dispersing aid.

Rhamnolipid derivatives as emulsifiers and dispersing aids

The present invention relates to a PEG free, stable, low viscosity classic oil-in-water emulsion and the use and preparation thereof. The oil-in-water emulsion comprises, A) a primary emulsifier selected from alkyl polyglucosides and long chained polyglycerol esters, B) a secondary emulsifier selected from short chained polyglycerol esters and short chained sorbitan esters, and optionally a thickener if the amount of secondary emulsifier is below 2.5 wt. %. The emulsion is a classic emulsion and can be sprayable. The emulsion is suitable to prepare spray or foam emulsion products with good application effect.

Peg free stable low viscosity oil-in-water emulsion and use thereof

The invention relates to novel polyglycerol esters with a particular oligomer distribution of the polyglycerol present, and to their use in particular in cosmetic formulations as, for example, emulsifier.
