FIELD: chemistry.
SUBSTANCE: invention concerns liquid detergent compositions with high stability during long-term storage. The liquid detergent composition includes fluid medium with water content up to 15 mass % and coated bleaching powder suspended in it. Dissolution time of the bleach is not less than 5 minutes; the bleach coating has at least two layers: inner layer includes one or more hydrate-forming non-organic salts as the main component, and outer layer comprises 0.2 to 5% of bleach and includes an alkali metal silicate with module of SiO2 to M2O (M is an alkali metal atom) over 2.5 as the main component. Preferable compositions include sodium percarbonate with an inner layer consisting mainly of sodium sulfate and an outer layer consisting mainly of 0.5 to 1.5 mass % of sodium silicate (with module of 3.2 to 4.2) as a bleach.
EFFECT: improved detergent efficiency and stability of the claimed composition.
