The invention provides new dietetic, laxative or cosmetic products which comprise an aqueous phase containing a proportion between 0.01 ane 10% by weight of water, an extract of lecithin enriched in phosphatidylcholine, which aqueous phase forms an emulsion with an oily phase comprised principally of paraffin hydrocarbons which are oily or solid at ambient temperature, for example vaseline and/or paraffin oil and of a lipo-soluble lecithin extract in proportions between 0.01 and 10% by weight of the paraffin hydrocarbons. The emulsion can moreover contain an inert mineral powder, such as kaolin, talc, calcium carbonate and/or monodiglycerides having a melting temperature above 50.degree. C. An application is the preparation of spreadable dietetic or laxative products or cosmetic milks or creams.
