The invention relates to functionalized polymers, a process for producing functionalized polymers and the use of functionalized polymers, especially in the field of personal care.

Functionalized polymers

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

An emulsion contains A) an alkyl ester quat of formula I wherein Ris an acyl radical of a fatty acid with a chain length of from 6 to 24 carbon atoms, with the proviso that a mass fraction of saturated, linear fatty acids with a chain length of from 12 to 24 carbon atoms, is more than 50% by weight, based on all acyl radicals R, wherein Ris an alkyl radical having 1 to 6 carbon atoms, wherein a=1-3 and b=1-3, with the proviso that a+b=4, B) at least one consistency regulator, and C) at least one cosmetic oil.

Emulsions comprising cationic emulsifiers based on MDIPA ester quats

A paint system contains an anti-fouling metal oxide and a fumed silica, wherein the fumed silica has a BET surface area of 150 to 400 m/g, a tamped density of 100 to 300 g/l and a thickening of less than 500 mPas.

Paint system containing anti-fouling metal oxide and fumed silica

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

Polyglycerol esters with a particular oligomer distribution of the polyglycerol

The invention relates to organomodified additives, emulsifiers, dispersants and/or active nourishing ingredients present in the silicon part of branched siloxane block copolymers, to the use thereof, in particular for producing cosmetic, dermatological or pharmaceutical formulations as well as care and cleansing products, and to the preparations as such. Specifically the invention relates to branched polysiloxanes having trifunctional T units as well as polyether groups, alkyl radicals of more than 7 carbon atoms or multi-hydroxy functional radicals.

Surface-modified, pyrogenically prepared silica is prepared by subjecting the pyrogenically prepared silica, which is in the form of aggregates of primary particles having a BET surface area of 300&#xb1;25 m/g and the aggregates have an average area of 4800-6000 nm, an average equivalent circle diameter (ECD) of 60-80 nm and an average circumference of 580-750 nm, to surface-modification in a known way. It can be used as a filler for controlling the rheology of liquid silicone rubber (LSR) systems.

Surface-modified, pyrogenically prepared silicas

Surface-modified, pyrogenically prepared silica is prepared by subjecting the pyrogenically prepared silica, which is in the form of aggregates of primary particles and possesses a BET surface area of 150&#xb1;15 m/g, the aggregates having an average area of 12 000-20 000 nm, an average equivalent circle diameter (ECD) of 90-120 nm and an average circumference of 1150-1700 nm, to surface-modification in a known way. It can be used as a filler for thickening liquid systems.

Fumed silicon dioxide powder in the form of aggregated primary particles having a BET surface area of 175&#xb1;15 m/g and a thickening effect, based on the BET surface area, of greater than 18 mPas g/mis hydrophobicized with polydimethylsiloxane. This hydrophobic fumed silica has a BET surface area of 110&#xb1;25 m/g. It can be used in epoxy resins. These epoxy resins in turn can be used as adhesives.
