Abstract

An encapsulated bleach particle is provided, comprising: (a) 1-30 % by weight of a coating including a gelled polymer material (as herein defined); (b) 99-70 % by weight of a core material selected from the group consisting of a peroxygen bleach compound, a bleach catalyst, and a bleach precursor. This particle was found to have both favourable storage stability and good solubility characteristics.
Furthermore, a process for producing encapsulated particles having said composition is provided.
