Abstract
A stable gelled composition, containing at least one lipophilic active agent sensitive to oxygen or to water or to both, and a solvent which contains, as gelling agent, at least one polysaccharide alkyl ether formed of units containing at least two different glycoside rings, each unit containing at least one hydroxyl group substituted with a saturated hydrocarbon alkyl group.
Claims26
A stable gelled composition, comprising at least one lipophilic active agent sensitive to at least oxygen, and a solvent, which composition comprises, as gelling agent, at least ethylated guar gum.
A method of stabilizing a lipophilic active agent which is sensitive to at least oxygen, which comprises adding to said lipophilic active agent a polysaccharide alkyl ether formed of units comprising at least two different glycoside rings, each unit comprising at least one hydroxyl group substituted with a saturated hydrocarbon alkyl group.
A method of treating acne or wrinkles in mammalian skin, which comprises applying to skin of a mammal in need thereof an effective amount of a stable gelled composition, comprising at least one lipophilic active agent sensitive to at least oxygen, and a solvent which composition comprises, as a gelling agent, at least ethylated guar gum.
