Pasty bleaching agent compsn. - comprising perborate mono:hydrate in liq. medium comprising addn. prod. of ethylene oxide with long chain satd. alcohol

摘要

Pasty compsn. contg. 40-70 wt.% perborate monohydrate in a liq. medium consists predominantly or entirely of addn. prods. of ethylene oxide and long chain satd. alcohols. - Pref. the liq. medium consists predominantly or wholly of an addn. prod. of 2-7 mols. ethylene oxide with 12-18 C alcohols. The compsn. may also contain (i) up to 10 wt.%, pref. 3-10 wt.% of another organic liq. chosen from paraffin oil, polypropyleneglycol, propylenecarbonate, ethanol, isopropanol, or mixts., of these and (ii) up to 10 wt.%, esp. 2-10 wt.% other additives e.g. anti-greying agents, optical brighteners, anhydrous inorganic salts, heavy metal complex formers, soaps and mixts. of these. Pref. the suspended solids are present at more than 90 % particles with a size of less than 50 microns, esp. 25 microns. USE/ADVANTAGE - Compsns. have good physical and chemical stability together with ease of dispensing measured portions and water solubility. They are useful as bleaching agents for washing textiles in domestic laundries and give rapid development of a high active oxygen availability. The compsns. are also useful as oxidising agents and disinfectants. - (Dwg.0/0 P01795)
