23 Jul Gel emulsion stabilized by rosin-based amine oxide surfactant
Abstract
The invention discloses gel emulsion stabilized by a rosin-based amine oxide surfactant, and belongs to the technical fields of colloid and interface chemistry. Dehydroabietic acid serving as a main synthetic material of the surfactant provided by the invention is derived from natural product rosin and is an environmentally-friendly surfactant. The critical micelle concentration of the rosin-basedsurfactant 6-dehydroabietylamine amine oxide at room temperature is 0.6*10<-3> mol.L<-1>. In an oil-water mixed system, the stable gel emulsion can be formed when the content of the surfactant 6-dehydroabietylamine amine oxide is only 0.22 percent by weight of a continuous phase. The volume fraction of a dispersed phase of the gel emulsion can be randomly adjusted within the range of 1 to 98 percent (v/v), which breaks through the conclusion that the internal phase volume ratio of conventional gel emulsion must be more than 74 percent. Meanwhile, the rosin-based surfactant 6-dehydroabietylamine amine oxide in the invention can enable most oil to form the stable gel emulsion which can be applied to multiple fields such as food, medicines, daily chemical products, tissue engineering, environmental protection, water pollution treatment and the like.
