Abstract
Novel colloidal products are described, containing calcium hydroxide in the center of micelles which are stabilised in an organic medium by a shell of a surfactant, in a reversed micelle. The products are obtained by reacting calcium oxide CaO, calcium hydride CaH.sub.2 or calcium metal with water in an organic medium in the present of a surfactant such as an alkine-earth or alkali metal alkylaryl sulphonate. They are used mainly as synthesis intermediates in reactions requiring lime to be introduced into an organic medium, or as detergent additives in lubricating oils.
