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 µm, 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.
L'invention concerne une préparation nettoyante se présentant sous la forme d'une émulsion d'huile dans l'eau. Les particules de la phase huile ont un diamètre moyen en volume ne dépassant pas 1 $(m)m. Un agent de conservation est présent, au moins dans la phase aqueuse. L'invention concerne également un procédé permettant d'obtenir cette préparation, consistant à former une émulsion grossière et à homogénéiser cette émulsion, puis à la diluer avec un liquide de dilution aqueux contenant l'agent de conservation. Cette préparation peut être appliquée sur un substrat pour constituer un article nettoyant, par exemple pour des mouchoirs pour bébés.
