SCHAUMREGULIERUNGSMITTEL AUF PARAFFIN-BASIS

摘要

In granular, pourable foam control agents, especially for use in washing and cleaning agents, consisting of a granular, tenside-free carrier (1) and a homogenous adsorbed anti-foaming mixture (II) containing no siloxane polymers or tensides but containing 70 to 95 wt % of a paraffin wax and 5 to 30 wt % of a bisamide derived from C2-7 diamines and saturated C12-22 carboxylic acids, the effectiveness over a wide temperature range, i.e. in particular in the cold-wash range and at medium washing temperatures, and the shelf and effective lives when mixed with conventional washing agent components are to be improved. This has been achieved by the development of an agent with no silicic acid, the carrier of which contains no phosphates and is soluble or dispersible in water and in which the paraffin wax is solid at room temperature and is liquid to 100 wt % at a temperature below 90 DEG C.
