摘要:
Hairsetting compositions comprise, in addition to customary auxiliaries and additives,(A) from 0.5 to 15% by weight of carboxyl-containing polymers which are water-dispersible or water-soluble in neutralized form and have a glass transition temperature of above 0.degree. C.,(B) from 0.5 to 30% by weight, based on the polymer (A) employed, of polysiloxanes containing primary, secondary or tertiary amino groups,(C) from 0 to 50% of a low molecular mass neutralizing agent.
摘要:
Dextran esters with a molecular weight of 10,000-10,000,000 and ester side chains which are derived from acids with 6-18 carbon atoms, where the degree of esterification is adjusted, depending on the number of carbon atoms in the side chains and the molecular weight, to a value of 0.04-1.1 so that the dextran esters are insoluble in water at room temperature and are broken down by colonic bacteria, and their use for coating and/or embedding pharmaceutical active ingredients or drug formulations.
