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:
The present invention relates to cosmetic preparations comprising novel polyurethanes or mixtures thereof as means for modifying rheological properties.
Abstract:
The invention relates to the use of at least one polymer which is different from polyethylene imine and which contains primary and/or secondary amino groups in cosmetic preparations for reducing the body odor caused by the formation of saturated and unsaturated C6-C12 aldehydes from the unsaturated fatty acids of the skin and/or the scalp.
Abstract:
The present invention relates to oligo- and polysaccharides containing amine groups. More particularly, the present invention is directed towards a new process to manufacture cationic cellulose oligomers. The new cationic oligo- or polysaccharides are shown to be useful ingredients in various aqueous compositions, inter alia as ingredients for personal care compositions.
Abstract:
The present invention relates to a 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. The present invention further relates to the thus obtained polyurethanes per se, to their use as thickener for aqueous preparations and to preparations containing such polyurethanes.
Abstract:
The invention discloses the use of a diol as a biocidal substance, characterised in that said use relates to a diol of formula (I), in which R1 and R2, independently of one another represent an organic group each having at least one C atom, or in which R1 and R2 together form a ring system that consists of at least 4 C atoms, and optionally can be substituted if required (referred to hereafter simply as 1,3-diol).
