Abstract
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 behavior without impairing the chemical stability of formulations comprising a peroxy acid bleach precursor, especially N,N,N',N'-tetraacetyl ethylene diamine.
Claims8
A detergent composition comprising:
- (a) from 15 to 90% weight of a non-aqueous liquid phase selected from the group consisting of liquid detergent surfactants, polyols, low molecular weight alcohols, liquid paraffins, benzyl alcohol, terpene and terpene derivatives, phthalate esters, natural nut oil, vegetable oil, fish oil, castor oil, amines, hydrocarbons, dioxane, dimethylformamide, liquid esters and mixtures thereof;
- (b) from 5 to 35% by weight of sodium perborate anhydrous obtained from dehydration of sodium perborate monohydrate, wherein the ratio by weight of sodium perborate monohydrate to sodium oxoborate is from 1.5:1 to 15:1;
- and
- (c) from 1 to 20% by weight of a peroxy acid bleach percursor.
