Japanese Patent JP4163703

B2

Composition (I) (in the form of an oil-in-water emulsion (comprising an oily phase (comprising at least one hydrocarbon-based oil) dispersed in an aqueous phase)) comprises an emulsifying system comprising at least one nonionic surfactant and at least one anionic surfactant. Composition (I) (in the form of an oil-in-water emulsion (comprising an oily phase (II) dispersed in an aqueous phase, where the globules of oil have a mean diameter of 50-500 nm)) comprises an emulsifying system comprising at least one nonionic surfactant (having a melting point of less than 45[deg]C and an (hydrophilic lipophilic balance) HLB of 10-15) comprising a polar portion comprising at least 5 oxyethylene groups and an apolar portion comprising at least one branched or unsaturated 14-22C alkyl chain; and at least one anionic surfactant, where (II) comprises at least one hydrocarbon-based oil (III) (having a molecular weight of greater than or equal to 400 representing at least 25 wt.% relative to the total weight of (II)) and the amount of triglyceride based oils representing less than 15 wt.% relative to the total weight of (II), where (III) is alkanes with melting point of less than 45[deg]C, and the weight ratio of the amount of oily constituents of the oily phase to the amount of emulsifying system is 0.8-3.5. Independent claims are also included for: (1) preparation of (I); (2) and an article comprising a water-insoluble substrate impregnated a with (I).
