PEROXYACID BLEACH PRECURSOR PARTICLE COATED WITH A WATER SOLUBLE ORGANIC ACID IN PARTICULATE FORM

摘要

Detergent additive compositions are disclosed in which a peroxyacid bleach precursor in the form of a substrate particulate having a mean specific area in the range of 0.05 to 0.9 m<2>/g, is coated with a solid particulate organic acid compound of median particle size < 450 micrometers, so as to give a Coating Index value (CI) in the range of from 0.01 to 9. A process for making the aditive compositions and detergent products containing them are also disclosed.
