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.
