Abstract
The present invention relates to a pharmaceutical and/or cosmetic composition in the form of a stabilized pseudoemulsion, characterized in that it is essentially comprised of (1) at least one aqueous phase containing a single gelifying agent selected from the group comprising polyoses, such as gelose, the xanthane gums, cellulose, alginates, semisynthetic derivatives of cellulose, and acrylic polymers such as Synthalen.RTM.; (2) at least one lipidic phase containing at least one consistency factor, with a ratio consistency factor/total lipidic phase between about 0.06 and 0.18, and in that said composition is free of surfactants. It also relates to a process for preparing such composition.
