<p>In liquid, pourable, thickened chlorine bleaching compositions, in which the thickening is produced by at least two different detergent active compounds, a buffer salt is included to improve their stability at lower chlorine levels and at reduced pH values. Typically, a composition comprises an aqueous solution of alkalimetal hypochlorite, thickened by means of a tertiary amine oxide and a saturated fatty acid soap, and contains an alkali-metal orthophosphate buffer system, at a chlorine content of 1-10% and a pH of 10-12.5. The compositions are useful in bleaching operations, especially in bleaching hard surfaces such as toilets, tiles, kitchen sinks etc.</p> |
