Abstract: Liquid detergent and cleaning agent composition comprises a liquid medium with a water (= 15 wt.%), and particulate coated bleaching agent(s). The bleaching agent(s) is suspended in the liquid medium from the series containing inorganic and organic peroxy compounds, The bleaching agent has a coating of at least two layers, preferably innermost layer (2-20 wt.%) and outer layer (0.2-5 wt.%). Liquid detergent and cleaning agent composition comprises a liquid medium with a water (=15 wt.%), and particulate coated bleaching agent(s). The bleaching agent(s) is suspended in the liquid medium from the series containing inorganic and organic peroxy compounds, The bleaching agent has a coating of at least two layers, preferably innermost layer (2-20 wt.%) and outer layer (0.2-5 wt.%). The innermost layer comprises hydrate-forming inorganic salt(s) as the main component(s). The outer layer comprises alkali metal silicate(s) with a modulus of silicon dioxide to alkali metal oxide of greater than 2.5 as the main component(s). The coated bleaching agent has a dissolving time of >= 5 minutes as measured for 95% dissolution in water at 15[deg]C and 2g/L.

Abstract: The invention relates to liquid detergent and cleaning agent compositions of high storage stability. They comprise a liquid medium with a water content of up to 15 wt.% and particulate coating bleaching agents suspended therein. The bleaching agent has a dissolving time of at least 5 minutes and a coating of at least two layers: The innermost layer comprises one or more hydrate-forming inorganic salts as the main component(s), and an outer layer, which makes up 0.2 to 5 wt.% of the coated bleaching agent, comprises alkali metal silicate(s) with a modulus of SiO2 to M2O (M = alkali metal) of greater than 2.5 as the main component(s). Preferred compositions comprise sodium percarbonate with an innermost layer of substantially sodium sulfate and an outermost layer of substantially 0.5 to 1.5 wt.% sodium silicate (modulus 3.2 to 4.2) as the bleaching agent.
