摘要:
A method for converting liquid nonionic surfactants to dry free flowing form is disclosed. The new method includes the mixing of the liquid nonionic material with specific particulate carrier materials in amounts varying from 30 to 85 percent. Suitable carrier materials include compounds having functional properties in detergent formulations. The free flowing nonionic surfactantcarrier pre-mix is very suitable for post-addition to spray dried detergent formulations in order to increase their content of nonionic surfactant.
摘要:
A composition for applying a non-permanent soil-release finish to fabrics comprising a mixture of a polycarboxylate polymer having an acid equivalent weight from about 110 to 175, and a mineral acid. A preferred carboxylate polymer is a copolymer of an ethylenically unsaturated monocarboxylic acid and an alkyl acrylate or methacrylate. The composition is particularly useful for applying a soil-release finish in the rinse cycle of a home laundry process.
