Abstract
A photobleaching liquid cleaning composition contains 1% to 79.9% by weight of detersive surfactant, with or without a detergency builder; 0.1 to 40% by weight of a chlorite, and at least about 20% by weight of a liquid base, the composition yielding a pH of at least 6 when dissolved in water at a concentration of about 0.5 g/l. The composition is suitable for the laundering of fabrics as well as for the use in the manual cleaning of dishes or in general purpose cleaning of hard surfaces.
Claims16
A liquid-based bleaching and cleaning composition consisting essentially of:
- (i) at least about 20% by weight of a liquid base,
- (ii) about 1% to about 79.9% by weight of a detersive surfactant with or without a detergency builder;
- and
- (iii) about 0.1% to about 40% by weight of a chlorite whereby said
- composition yields a pH of at least 6.0 when dispersed in water at a concentration of about 0.5 g/l and provides a bleaching effect when exposed to a source of ultraviolet light.
A method of bleaching and cleaning fabrics comprising the steps of:
- (i) preparing a treatment liquid comprising
- (a) at least about 20% by weight of a liquid base;
- (b) about 1% to about 79.9% by weight of a detersive surfactant with or without a detergency builder;
- and
- (c) about 0.1% to about 40% by weight of a chlorite;
- (ii) contacting said fabric with said treatment liquid;
- and then
- (iii) exposing said fabric contacted with said treatment liquid to a source of ultraviolet light whereby a bleaching and cleaning effect is obtained.
