Abstract (en)
The present invention relates to a process of bleaching a fabric which comprises the steps of : diluting in an aqueous bath a liquid aqueous composition in its neat form, having a pH below 7 and comprising a persulfate salt, contacting said fabric with said aqueous bath comprising said liquid composition, and subsequently rinsing said fabric with water. This bleaching process delivers effective bleaching performance and effective overall stain removal performance while being particularly safe to the fabrics and fabric colours
