The invention relates to the use of polyolethers as additives in aqueous polymer dispersions for producing porous polymer coatings, preferably for producing porous polyurethane coatings.

Use of polyolethers for producing porous plastic coatings

The use of long-chain citric acid esters as additives in aqueous polymer dispersions for production of porous polymer coatings, preferably for production of porous polyurethane coatings, is described.

Use of long-chain citric acid esters in aqueous polyurethane dispersions

The invention relates to a process for producing a porous polyurethane coatings, using a polyol ester as additives in an aqueous polymer dispersion, the process comprising the steps of a) providing a mixture comprising an aqueous polymer dispersion, a polyol ester, and an additive, b) foaming the mixture to give a homogeneous, fine-cell foam, c) adding at least one thickener to establish the desired viscosity of the wet foam, d) applying a coating of the foamed polymer dispersion to a suitable carrier, e) drying the coating. The invention further relates to a phosphorylated polyol ester.

Process for producing porous polyurethane coatings using polyol ester additives

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 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 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.

Polyglycerol esters with a particular oligomer distribution of the polyglycerol

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