Disclosed are nonaqueous, bleach-containing liquid laundry detergent compositions which are in the form of a suspension of particulate material, including peroxygen bleaching agent and an alkyl sulfate anionic surfactant, dispersed in a liquid phase containing an alcohol ethoxylate nonionic surfactant and a nonaqueous, low-polarity organic solvent. Such compositions provide especially desirable cleaning and bleaching of fabrics laundered therewith and also exhibit especially desirable chemical and phase stability.
L'invention concerne des compositions détergentes liquides non aqueuses contenant un agent de blanchiment et se présentant sous la forme d'une suspension d'un matériau en particules, y compris un agent de blanchiment péroxygéné et un tensioactif anionique de sulfate d'alkyle, dispersée dans une phase liquide contenant un tensioactif non ionique d'éthoxylate d'alcool, ainsi qu'un solvant organique non aqueux à polarité basse. Ces compositions permettent d'effectuer avantageusement le nettoyage et le blanchiment de tissus et présentent également une stabilité chimique, ainsi qu'une stabilité de phase, particulièrement favorables.
