Definitions

  • the present invention relates to a liquid bleaching composition which is suitable both for laundry and household applications.
  • Compositions herein are particularly suitable in laundry applications, as a prewash bleaching composition.
  • Liquid bleaching compositions are well known In the art. Amongst the different bleaching compositions available, those relying on bleaching by hypochlorite are often preferred, mainly for performance reasons. These hypochlorite-based compositions are typically used in dilute form and are suitable both for laundry and household applications. However a major drawback associated with chlorine-based compositions is the malodor they generate during and after use. Indeed, not only does the composition itself smell chlorine bleach, but the malodor remains noticeable on fabrics or surfaces which have been treated with said compositions, as well as on the skin of the user of the composition, even after the bleaching composition has been thoroughly rinsed away.
  • Formulators have tried to solve that problem by designing perfumed chlorine-based bleaching compositions. However, this has proved difficult mainly for two reasons. Firstly, only a few perfume components are available which are stable in a strong oxidative environment such as a chlorine-based bleaching composition, resulting in limited flexibility in designing perfumes for such compositions. Secondly, chlorine bleach odor is strong and therefore difficult to mask even when perfumes are present.
  • a chlorine-based bleaching composition suitable for use in diluted form could be formulated, which exhibits a reduced chlorine odor upon use, by adding a pH buffering means, preferably a carbonate salt and/or a silicate salt in an aqueous bleaching composition, said composition comprising an alkali metal hypochlorite (2% - 10% by weight) and a bleach stable perfume and being formulated, at a pH of from 11.5 to 14.
