摘要:本论文针对色素的缓释性能,研究了不同测试条件对缓释性能评价的影响。主要包括不同供给液体系,如纯水、化妆水,O/W乳液、W/O乳液、油相体系以及不同接收液体系,如PBS 缓冲溶液、PBS 缓冲溶液与水的不同比例、有机溶剂、有机溶剂与 PBS 缓冲溶液的不同比例、以及不同的油相体系对缓释性能评价的影响。实验结果表明:不同供给液体系对水溶性染料及油溶性染料的影响不同。O/W 乳液体系中水溶性染料的渗透量比油溶性染料高,W/O 乳液体系中油溶性染料的渗透量比水溶性染料高;不同接收液体系对供给液渗透性能的影响也不同,PBS 缓冲液与有机溶剂有利于渗透,PBS 缓冲液与水的不同比例对缓释性能的影响不同。56985

Study on effect of different test conditions for slow release performance
Abstract:This thesis is aimed at the slow release property of pigment,The effects of different test conditions on the evaluation of slow release properties were studied.Mainly including effects of different liquid supply system,such as water, toning lotion, O/W emulsion, W/O emulsion, oil phase system and different receiving liquid system,such as PBS buffer solution, PBS buffer solution with different ratios of water, organic solvents, organic solvents and PBS buffer solution of different ratios, as well as the different oil phase.Experimental results show that the effect of different liquid supply systems on water soluble dyes and oil soluble dyes is different.The permeability of water soluble dyes in O/W emulsion system is higher than that of oil soluble dyes, the permeability of oil soluble dyes in W/O emulsion system is higher than that of water soluble dyes.The influence of different receiving liquid systems on the permeability of the supply liquid is also different.PBS buffer solution and organic solvent are beneficial to penetrate,The effects of different proportions of PBS buffer solution and water on the slow release performance are different.
