摘要:
The invention relates to textile softener concentrates based on pentaerythritol and/or dipentaerythritol fatty acid partial esters. The dispersibility of such softener concentrates in cold water can be significantly improved by addition of a special emulsifier combination of quaternary ammonium compounds and nonionic compounds. The quaternary ammonium compounds are quaternized alkoxylated alkylamines and/or esterquats. Ethoxylated and/or propoxylated fatty acids or fatty acid esters and end-capped fatty alcohol polyglycol ethers are suitable nonionic emulsifiers.
