Abstract
A cleansing preparation is provided in the form of an oil-in-water emulsion. The oil phase particles have a median particle diameter by volume of not more than 1 &mgr;m, and a preservative is present in at least the aqueous phase. A method is described of making this preparation, in which a coarse emulsion is formed, the coarse emulsion is homogenized, and the homogenized emulsion is diluted by an aqueous dilution liquid containing the preservative. Cleansing articles, for example baby wipes can be made in which a substrate carries the cleansing preparation.
