Abstract

A detergent composition which imparts a good "hand" to textiles washed therewith comprises (a) a non-ionic detergent such as a fatty alkanolamide, a fatty ester of a polyol, and ethylene and/or propylene oxide condensates with such compounds or with fatty acids, alcohols, amines, amides, mercaptans or alkylphenols, or condensates of propylene oxide with polyethylene glycol, and (b) a hydrazinium compound containing at least one straight hydrocarbon chain of more than 8 carbon atoms, preferably of formula <FORM:0895456/III/1> wherein R is an alkyl, alkenyl or alkadienyl radical of 16-24 carbon atoms, R1 and R11 (which may be the same or different) are alkyl radicals of 1-24 carbon atoms, alkenyl radicals of 2-24 carbon atoms, or alkadienyl radicals of 4-24 carbon atoms, and A is an anion, suitably chloride. Compound (b) is generally surface active and is usually present in amounts of at least 3% by weight of the composition. The composition usually also includes builder salts such as sodium carbonate, bicarbonate, sulphate, silicate, borates, phosphates, and polyphosphates, chlorinated trisodium phosphate, carboxymethylcellulose and optical bleach. In a preferred embodiment, the composition comprises by weight 10-35% of non-ionic detergent (a), 60-85% of inorganic builder, at least 3% of hydrazinium compound (b), 1% sodium carboxymethylcellulose, and traces of optical bleach. Specifications 884,625 and 884,775 are referred to.ALSO:A good "hand" is imparted to textiles, especially of cotton, by washing in a composition comprising (a) a non-ionic detergent such as a fatty alkanolamide, a fatty ester of a polyol, and ethylene and/or propylene oxide condensates with such compounds or with fatty acids, alcohols, amines, amides, mercaptans or alkylphenols, or condensates of propylene oxide with polyethylene glycol, and (b) a hydrazinium compound containing at least one straight hydrocarbon chain of more than 8 carbon atoms, preferably of the formula <FORM:0895456/IV (c)/1> wherein R is an alkyl, alkenyl or alkadienyl radical of 16-24 carbon atoms, R1 and R11 (which may be the same of different) are alkyl radicals of 1-24 carbon atoms, alkenyl radicals of 2-24 carbon atoms or alkadienyl radicals of 4-24 carbon atoms, and A is an anion, suitably chloride.
