    Abstract: Bleaching agents contg. Na percarbonate (I) coated with a borate-contg. compsn. (II) are claimed. Also claimed are bleaching detergent compsns. contg. 1-99wt.% of (I) coated with (II).(II) may contain 10-100wt.% borate, esp. Na metaborate, opt.together with a sequestering agent (esp. EDTA or NTA) and/or an alkali metal silicate or a Mg cpd. The amt. of (II) may be 0.1-30% of the wt.of (I).Coating (I) with (II) stabilises it against decompsn., esp. in detergent compsns. which have a low or zero phosphate content and/or contain aluminosilicates
