Thirteen kinds of monohalogenoacyl substituted aromatic derivatives were synthesized and tested their antitrichophyton effect. On anilide, Cl substitution of p-position is 30 times as strong as that of o-position, and Cl substitution is 33 times as strong as Br substitution. The double bond of acyl group of monohalogenoacyl substituted aromatic amide derivatives did not show strong fungical effect, and there was no difference of fungical effect between cis and trans.
A bleach product comprising a percompound contained within a closed water-insoluble but water-permeable bag of fibrous material, provided with a protective water-impermeable coating which is removable in water at a temperature of 30-75°C, preferably 35-65°C. The bleach product can be used in fabric washing machines for bleaching fabrics with or without a detergent product.

This invention relates to peroxygen bleaching activator compounds and bleaching compositions. The peroxygen bleach activator compounds, used in combination with peroxygen bleach compounds which yield hydrogen peroxide in an aqueous solution, provide effective and efficient bleaching of textiles over a wide range of temperatures. In a highly preferred embodiment the bleaching compositions of the invention are detergent compositions. The method of preparing these peroxygen bleach activator compounds is also claimed.

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.
