Abstract (en)
[origin: DE19859427A1] The invention relates to gels or low viscosity transparent or translucent oil-in-water microemulsions which comprise a water phase and an oil phase and which essentially consist of constituents that are not easily volatized. These constituents contain at least one phospholipid and at least one oil-in-water emulsifier and optionally contain at least one W/O emulsifier which can be obtained by adding the water phase with the constituents thereof to the oil phase with its constituents, especially with the phospholipid and the O/W emulsifier and optionally with the W/O emulsifier, whereby the phases are mixed together and a gel state is attained. If a low viscosity O/W microemulsion is desired, additional parts of the water phase are added and the phases are mixed, whereby the phases can optionally contain additional auxiliary, addition and/or active agents.
