New grade of sodium perborate anhydrous obtained from dehydration of sodium perborate monohydrate, wherein the ratio by weight of sodium perborate monohydrate to sodium oxoborate is at least 1.5:1, method of manufacturing and use thereof in detergent compositions are disclosed. The new grade of sodium perborate anhydrous is particularly suitable for use in non-aqueous liquid detergent compositions to improve dispensing behaviour without impairing the chemical stability of formulations comprising a peroxy acid bleach precursor, especially N,N,N',N'-tetraacetyl ethylene diamine.
本发明公开了由一水过硼酸钠脱水制得的新牌号无水过硼酸钠,其中一水过硼酸钠与氧硼酸钠的重量比至少为 1.5:1,并公开了其制造方法及其在洗涤剂组合物中的用途。这种新牌号的无水过硼酸钠特别适用于非水性液体洗涤剂组合物,可改善分配性能,同时不影响含有过氧酸漂白剂前体(尤其是 N,N,N',N'-四乙酰乙二胺)的配方的化学稳定性。
