Microemulsion gels a) based on oil in water type, comprising an oil phase, substantially consisting of not easily volatile constituents, and an aqueous phase containing one or more O/W emulsifiers free from ethylene oxide and propylene oxide and possibly one or more additional O/W emulsifiers, an emulsifier content which is lower than 20 wt. % related to the full weight of the microemulsion, obtained in such a way that a mixture of basic constituents, consisting of an aqueous phase, an oil phase, one or more O/W emulsifiers, possibly one or more additional O/W emulsifiers, possibly other auxiliary, additional or active agents, is made to react against each other in a mixing ratio so that a microemulsion can be obtained and b) in which droplets of discontinuous oil phase are bound to each other by one or more cross-linking substances, whose molecules are characterized by at least one hydrophylic area having a suitable expansion for bridging of distance between each microemulsion droplet and at least one hydropobic area, which can interact hydrophobically with the microemulsion droplets.
