The invention relates to low-viscosity, in particular atomizable, oil-in-water type microemulsions containing phospholipids. Said microemulsions comprise an aqueous phase and an oily phase, which are essentially composed of poorly volatile constituents and contain at least one phospholipid, at least one oil-in-water emulsifier and optionally at least one W/O emulsifier. The emulsions are obtained as follows: the aqueous phase with its constituents is added to the oily phase with its constituents, in particular the phospholipid, the O/W emulsifier and optionally the W/O emulsifier, whereby the phases are mixed together to obtain a gel state; if a low-visosity O/W microemulsion is desired, other parts are added to the aqueous phase and the phases are mixed; said phases can, if so desired contain additional adjuvants, additives and/or active ingredients. |
