Abstract:
An oil-in-water emulsion for application on a skin surface, the emulsion comprising an oily phase and an aqueous phase,said oily phase comprising a first lipid of vegetable or animal origin, the emulsion being stabilized by containing at least one surfactant/emulsifier, the at least one surfactant/emulsifier being substantially removed from a skin surface onto which the emulsion has been applied and from the emulsion by flushing with liquid, thereby leaving at least a part of the oily phase on the skin, and the emulsion when diluted with tap water having a degree of hardness of about 18 degrees in a volume of 100 parts of water to one part of the emulsion at ambient temperature, being separated into at least two distinct phases after standing for 24 hours at ambient temperature, wherein the oil-in-water emulsion has a pH value of at least 6, and at least about 50% w/w of the total concentration of the at least one surfactant/emulsifier which is a fatty acid derivative, wherein said derivative has a fatty acid component which is a saturated or unsaturated C10-C24 hydrocarbon carboxylic acid or mixtures thereof.
