Abstract:
The present invention relates to a composition comprising an active ingredient soluble in water at 20°C at no greater than 10 g/L, and a hyperbranched polyester linked to a polar polymer comprising a polycondensate or a polymer comprising ethylene unsaturated monomers. The invention further relates to said hyperbranched polyester and to a method for the production thereof. The invention further relates to the use of the hyperbranched polyester for solubilizing the active ingredient in aqueous compositions.
Abstract:
The invention relates to aqueous formulations containing (A) at least one pigment, (B) at least one carbodiimide, (C) at least one statistical polyurethane, and (D) optionally, at least one polyacrylate which does not contain any copolymerized comonomers, which formulations can split off one equivalent of formaldehyde per mole due to the action of heat at temperatures ranging from 100° to 250°C.
Abstract:
The present invention relates to a one-stage method for producing polyurethanes which contain at least three hydrophilic segments, at least four hydrophobic segments, optionally allophanate segments and/or isocyanurate segments and which are produced in the presence of alkaline earth metal carboxylates or zinc carboxylates. The present invention further relates to the thus obtained polyurethanes, to their use as thickener for aqueous preparations and to aqueous preparations containing such polyurethanes.
Abstract:
Disclosed is a use of a polymer solubilizer for increasing the soil mobility of a low-solubility insecticide, the polymer solubilizer being such that the insecticidal active substance in a 1 wt % aqueous solution of the polymer solubilizer at 25°C and 1.01325 bar is at least 40 times more soluble than under the same conditions in pure water, and the weight ratio of active substance : solubilizer being = 1.
Abstract:
The present invention relates to cosmetic preparations comprising novel polyurethanes or mixtures thereof as means for modifying rheological properties.
Abstract:
Disclosed are keratin-binding polypeptide agents in the form of conjugates (A'B'C') or (A'B'C'D') comprising (A') a polypeptide sequence derived from a keratin-binding polypeptide (A), and (B') a statistical average of at least one polymer chain derived from a water-soluble or water-dispersible polymer (B) that carries lateral and/or terminal reactive functional groups (b1) and is selected in such a way as to form a homogeneous aqueous solution or dispersion along with the keratin-forming polypeptide (A) to be reacted to form the conjugate (A'B'C') or (A'B'C'D') in standard conditions, the polypeptide (A) in said aqueous solution or dispersion still having a keratin-binding activity. (C') At least one linker group links the polymer chain (B') to the polypeptide sequence (A'), and (D') optionally, a statistical average of at least one effector group is linked to the polymer chain (B'). Also disclosed are a method for the production of said active polypeptide substances and the use thereof for modifying keratin and keratin-containing materials and producing cosmetic and pharmaceutical compositions.
