Abstract: The stable multiple emulsion of the X/O/Y type contains at least one X/O phase in which X is an oil-immiscible component and O an oil phase. The X/O phase can contains an active substance, possibly in solid form, for example for medical, cosmetic or technical applications. The Y phase can be an aqueous phase, an aqueous liquid, preferably liquid-crystalline, gel or a W/O/W emulsion and serves as carrier for the at least one X/O phase. The X/O phase is produced using an emulsifier that has an HLB value equal to or less than 6 and/or is a W/O emulsifier. The preparation of the X/O phase itself and its diffusion in the Y phase are done with standard stirring tools. The drops of the X/O phase have long-term stability and, even when greatly diluted, do not interact with the Y phase or the drops or other X/O phases dispersed therein.

Abstract: Emulsifier composition is a mixture of polyglycerol fatty acid ester (n.gtoreq.4) and the lactylate of a fatty acid (C.gtoreq.8) or its salt and is used to manufacture a wide range of different O/W emulsions, e.g. sunscreen emulsions for cosmetics. The polyglycerol fatty acid ester preferably has an HLB value.ltoreq.8. The emulsifier composition can additionally contain a lipophilic emulsifier.
