Abstract

An encapsulated active substance for a manual detergent for hard surfaces comprises an essentially anhydrous active substance with at least one surfactant and at least one liquid polymer carrier encapsulated in a water-soluble or water-dispersible capsule, the active substance containing: less than 25 wt. % of carrier; at least one unbranched or branched, acryclic or cyclic, saturated or unsaturated alcohol with 1 to 10 carbon atoms and one or two primary, secondary or tertiary hydroxy groups and a carbon chain optionally having one or more —O— groups; or being free of glycerol. The encapsulated active substance can be used as a manual detergent for hard surfaces.
