Abstract (en)
[origin: EP0879874A2] Encapsulated agents for manual cleaning, especially dishwashing, comprise (a) an agent containing 20-100 wt.% alkyl- and/or aryl-polyether sulphate surfactant(s) of formula R<1)<CHR<2>CH2O)xOSO3M (I) and/or alkyl- and/or aryl sulphate surfactant(s) of formula R<3>OSO3M (II) and (b) a water-soluble or water-dispersible encapsulating material (III). In the formulae, R<1>, R<3> = 6-22 carbon (C) aliphatic hydrocarbyl and/or aromatic hydrocarbyl, optionally substituted by 1-18 C alkyl; R<2> = hydrogen (H) and/or 1-4 C alkyl; x = 0.1-6; M = a metal cation or ammonium ion. Also claimed is the use of agents containing anhydrous surfactant, encapsulated in (III), as manual cleaning or dishwashing agents.
