Abstract:
A liquid detergent composition for washing dishes by hand or textiles by hand comprising an effective amount of a foaming aqueous medium (FAM) which can form stable foams in the presence of grease (G), said foaming aqueous medium (FAM) comprising water and at least one base surface-active agent (BSA) which can disperse and/or dissolve the grease (G) in the water and which comprises at least one amphiphilic additive (ADD) compatible with said base surface-active agent (BSA), said amphiphilic additive (ADD) exhibiting, at a concentration of 0.1% by weight in water, a surface tension .gamma..sub.(ADD) water/air of less than 25 mN/m at 25.degree. C. and exhibiting an affinity for the grease (G) which is less than that of the base surface-active agent (BSA) for said grease (G), wherein said amphiphilic additive (ADD) comprisessurface-active agents of the formulaF(CF.sub.2 CF.sub.2).sub.3-8 CH.sub.2 CH.sub.2 SCH.sub.2 CH.sub.2 COOLiF(CF.sub.2 CF.sub.2).sub.3-8 CH.sub.2 CH.sub.2 O(CH.sub.2 CH.sub.2 O).sub.y HF(CF.sub.2 CF.sub.2).sub.3-8 CH.sub.2 CH.sub.2 SCH.sub.2 CH.sub.2 N.sup.+ (CH.sub.3).sub.3 CH.sub.2 SO.sub.4.sup.-F(CF.sub.2 CF.sub.2).sub.3-8 CH.sub.2 CH(OCOCH.sub.3)CH.sub.2 N.sup.+ (CH.sub.3).sub.2 CH.sub.2 CH.sub.2 CO.sub.2.sup.-perfluoroalkyl betaines,ethoxylated polyfluoroalcoholspolyfluoroalkyl ammonium saltssurface-active agents, the hydrophilic part of which comprises one or more saccharide unit(s) comprising from 5 to 6 carbon atoms and the hydrophobic part of which comprises a unit of formula R.sub.F (CH2)n.sup.-, where n can range from 2 to 20, and R.sub.F represents a perfluoroalkyl unit of formula C.sub.m F2.sub.m+1 with m being able to range from 1 to 10,polyacrylates exhibiting R.sub.F (CH.sub.2).sub.n -- groups, where n can range from 2 to 20, and R.sub.F represents a perfluoroalkyl unit of formula C.sub.m F.sub.2m+1 with m being able to range from 1 to 10.
