Abstract (en)
Foam-controlled solid laundry detergent containing anionic surfactants, antifoam, and nonionic surfactant(s) comprising (poly)alkylene glycol ester alkyl ether (I) with a 6-22 carbon (C) acyl group. Foam-controlled solid laundry detergent containing anionic surfactants, antifoam, and nonionic surfactant(s) comprising (poly)alkylene glycol ester alkyl ether of formula (I) with a 6-22 carbon (C) acyl group. R<1>COO(CH2CHR<3>O)xR<2> (I) x = 1-20; R<1>CO = linear or branched, saturated or unsaturated 6-22C acyl; R<2> = linear or branched 1-4C alkyl; R<3> = hydrogen (H), methyl or ethyl. An Independent claim is also included for the use of (I) as foam-reducing compound for solid laundry detergents containing anionic surfactants and antifoam.
