Emulsions, especially water-in-silicone oil emulsions, containing fragrances or perfumes in the oil phase of the emulsion, are made by (i) preparing an oil phase containing as ingredients a vinyl-type polymer having in its molecular chain a carbosiloxane dendrimer; a volatile linear silicone oil, a non-volatile linear silicone oil, a volatile cyclic silicone oil, or an organic oil; a surfactant; an oil soluble emollient; and a fragrance or perfume; and mixing the ingredients of the oil phase; (ii) preparing an aqueous phase containing as ingredients water, a thickening agent, and a water soluble emollient, and mixing the ingredients of the aqueous phase; (iii) adding the aqueous phase to the oil phase; and (iv) mixing the two phases to form the emulsions in which the fragrance or perfume remains in the oil phase of the emulsion. The vinyl-type polymer is preferably obtained by polymerising a vinyl monomer with a carbosiloxane dendrimer macromonomer. The emulsions can be used as components of various products, especially cosmetic products. The products have particular utility in treating hair, skin or underarm areas of the human anatomy.
