Stearic Acid/17 Oleic Acid/8 Zein G200/100 Aq. Ethanol, 90%/240
配制方法:
The stearic acid is dissolved in the ethanol at 35-40'C, as it is not soluble in 90% aqueous ethanol at room temperatures. The propylene glycol is added and the solution cooled to 30'C. The Zein G200 is added slowly with good agitation and stirred until dissolved. If desired the formulation may be further diluted with 90% aqueous ethanol.
