PARTICULATE FOAM-REGULATING AGENT MADE FROM PARAFFIN

摘要

The invention concerns free-flowing granular foam-regulating agents intended for use, in particular, in washing and cleaning agents and consisting of a granular, surfactant-free carrier material (I) with, adsorbed on it, a homogeneous anti-foaming mixture (II) containing 70 to 95 % by wt. of a paraffin wax plus 5 to 30 % by wt. of a bisamide derived from C2-7 diamines and saturated C12-22 carboxylic acids. The aim of the invention is to improve the effectiveness of such foam-regulating agents, in particular in cold-wash conditions and at medium washing temperatures. This is achieved by using an agent whose paraffin wax is solid at room temperature and of which at least 35 % by wt., but less than 100 % by wt., becomes liquid at a temperature of 40 DEG C.
