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 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 provides for the use of specific microemulsions comprising quaternary ammonium compounds for production of clear fabric softener formulations having improved performance properties, and also the corresponding formulations and a process for production thereof.

The invention provides derivatives of rhamnolipids, formulations comprising these, and the use thereof.

Rhamnolipid amides for hair scent retention

The invention provides ester derivatives of rhamnolipids, formulations comprising these, and the use thereof.

Rhamnolipid esters as nonionic surfactants for cosmetic use

The invention provides compositions comprising at least one rhamnolipid and at least one siloxane, characterized in that the weight ratio of rhamnolipid to siloxane is from 5,000,000:1 to 100:1, preferably from 500,000:1 to 1000:1, particularly preferably from 25,000:1 to 2500:1. In another embodiment, the invention provides compositions include rhamnolipid in an amount of from 0.5% by weight to 70% by weight, preferably from 2% by weight to 60% by weight, particularly preferably from 3% by weight to 50% by weight, where the percentages by weight refer to the total composition.

Skin cleansing composition containing rhamnolipid and siloxane

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

A process for isolating rhamnolipids is provided. The process includes providing an aqueous medium containing at least one rhamnolipid and having a pH of less than 6. Next, the aqueous medium is brought into contact with at least one organic solvent to provide a multiphase system and then the aqueous phase is separated off. The pH is then increased to a value of 6 or more to provide a multiphase organic system. Next, a rhamnolipid-enriched organic phase is separated off. An optional step of further purifying the rhamnolipid may be performed.

Process for the isolation of rhamnolipids

The present invention provides a curable coating composition comprising at least one linear or cyclic polysiloxane containing at least one quaternary ammonium group, a process for producing the aforesaid coating composition, and a process for producing a coating with the curable coating composition, and also the coatings and coating compositions themselves that are obtainable by the processes described.

Coating composition comprising polysiloxane quats

The invention relates to microemulsions which comprise, as oil phase, a polysiloxane containing at least one quaternary ammonium group, methods for production thereof and also to the use of such microemulsions.

Microemulsion of polysiloxanes containing quaternary ammonium groups, production and use thereof

The present invention relates to a process for producing a polyurethane foam, where the blowing agent used is present in the supercritical or near-critical state. A reaction mixture is introduced into a closed mould, where the closed mould has been set up in such a way that its interior volume and/or the pressure prevailing in its interior can be altered after the introduction of the mixture by external influence. Through the selection of the surfactant it is possible to obtain microemulsions of the blowing agent in the polyol phase. The invention further relates to a nanocellular polyurethane foam obtainable by the process of the invention.
