Abstract
Novel film-forming gel compositions are described comprising from 10-40% by weight of a water dissipatable polymer, from 10 to 40% by weight of humectants and 20-60% by weight of water. The gel compositions may also be in the form of an emulsion comprising from 15-30% by weight of a water dissipatable polymer, from 15 to 35% by weight of humectants, up to 40% by weight of emollients, from 15 to 35% by weight water and a small amount of emulsifier. Additionally the gels of the present invention may contain optional agents such as, for example, coloring agents, pigments, preservatives, medical agents, cosmetic agents or agents to modify the refractive index of the gel.
