PARTICULATE DETERGENT ADDITIVE PRODUCT ABSTRACT A detergent additive product intended to enhance removal of oxidisable and oily stains from textiles comprising a substantially water impermeable container enclosing an organic matrix consisting of 30-85% by weight of a normally solid water soluble ethoxylated nonionic compound and 15-70% by weight of an organic peroxybleach precursor, optionally with 1-75% by weight of the matrix of other water soluble detergent components especially cationic surfactants, organic chelating agents and soil suspending agents. The particulate product has a maximum dimension in the range 1-4mm, a penetrometer indentation of less than 1 mm, a wicking value (resistance to monionic bleeding) < 10 and should disperse in aqueous inorganic persalt-containing detergent solution to release at least 50% of the theoretically available bleach within 8 minutes. In a preferred granular form, the product is coated with 1-30%, by weight of the matrix, of a powder coating which may be organic or inorganic.
