油溶性维生素、激素等的注射剂以及挥发油、挥发性物质等的芳香水,大多使用非离子型表面活性剂作增溶剂。作者选用挥发油中的成分苯甲醛,研究在吐温20水溶液中,抗氧剂对其自动氧化的影响。通过测定不同浓度吐温20水溶液的表面张力,得出临界胶团浓度为5.0×10~(-4)M。将浓度为5.0×10~(-2)M的苯甲醛和2.5×10~(-4)M 的抗氧剂,分散于浓度为1.0×10~(-5)M、5.0×10~(-4)M、5.0×10~(-2)M 的吐温20水溶液中,分别形成溶液、乳状液、增溶液三种分散体系。取各
Injections of oil-soluble vitamins, hormones and the like, as well as aromatic oils such as volatile oils and volatile substances, non-ionic surfactants are often used as solubilizers. The author chose benzaldehyde as a component of the volatile oil to study the effect of antioxidants on the autoxidation in an aqueous solution of Tween 20. By measuring the surface tension of different concentrations of Tween 20 aqueous solution, the critical micelle concentration was 5.0 × 10 ~ (-4) M. The benzaldehyde with the concentration of 5.0 × 10 ~ (-2) M and the antioxidant with the concentration of 2.5 × 10 ~ (-4) M were dispersed in a solution of 1.0 × 10 ~ (-5) M, 5.0 × 10 ~ 4) M, 5.0 × 10 ~ (-2) M Tween 20 aqueous solution, respectively, the formation of the solution, emulsion, solution of three dispersed systems.
