Compositions for cold water washing containing N-substituted {107 -hydroxyalkane carboxylic acid amides

摘要

Cold-water active washing agent compositions comprising (A) FROM 0.3% TO 2.5% BY WEIGHT OF AN N-substituted- omega -hydroxyalkane carboxylic acid amide obtained by reacting substantially equimolar amounts of an N-(C8-20-alkyl)-di-amino-C2-6-alkane with a lactone having 4 to 7 ring atoms, (B) A TENSIDE MIXTURE OF ANIONIC TENSIDES OF THE SULFONATE AND/OR SULFATE TYPE AND/OR ZWITTERIONIC TENSIDES, OPTIONALLY TOGETHER WITH SOAPS AND/OR NONIONIC TENSIDES, IN AN AMOUNT SUFFICIENT TO GIVE A WEIGHT RATIO OF (A) TO (B) OF FROM 1:50 TO 1:2, PREFERABLY 1:20 TO 1:
