摘要:
There is a bleaching composition comprising alkali metal percarbonate as an oxygen releasing compound, and alkali metal carbonate particles or bicarbonate particles of defined size (mean particle size of 300 .mu.m or greater) wherein fewer than 10% of the particles have a particle size below 250 .mu.m. The said composition comprises discrete particles of said alkali metal percarbonate salt and said alkali metal carbonate or said alkali metal bicarbonate. The particle bleaching composition may form a component of a machine dishing composition, a bleach booster composition or in particular a laundry detergent composition. The percarbonate has increased storage stability in the composition of the invention.
摘要:
There is provided a granular, silicate-built, phosphate free laundry detergent composition comprising fine alkali metal percarbonate particles having mean particle diameter below 450 .mu.m, preferably below 400 .mu.m, wherein no more than 20%, preferably no more than 10%, of the particles have a diameter above 710 .mu.m, said particles having a coating comprising one or more soluble inorganic salts. The salts may be selected from alkali or alkaline earth metal carbonates, sulphates, chlorides and nitrates. The coated percarbonate particles have improved stability to storage and are capable of dissolving quickly in wash liquor.
摘要:
Low density detergent compositions, containing sulfate and an acidic dispersing aid combined with an alkaline source, which are capable of reacting together to produce a gas, are suitable for use in laundry washing methods.
摘要:
This invention relates to a detergent composition comprising an anionic surfactant and a cationic surfactant, an acid source and an alkali source capable of reacting together in the presence of water to produce a gas.
摘要:
There is provided a detergent composition containing an amylase enzyme and a builder system comprising an aluminosilicate zeolite, a crystalline layered silicate and most preferably an organic polymeric compound wherein the weight ratio of said crytalline layered silicate to said amylase enzyme (120 KNU/gram activity basis) is from 7:1 to 20:1. In one preferred aspect the detergent composition contains a bleaching system capable of providing delayed release of an organic peroxyacid to a wash solution.
