Preparation and Properties of Litsea cubeba Essential Oil Microemulsion
摘要
Abstract
A series of Litsea cubeba essential oils(LCO)were compounded and their hydrophile-lipophile balance value(HLB).The phase transition temperatures required for preparing microemulsions were determined using the phase transition temperature method.Then,the pseudo-ternary phase diagram method was employed to establish the range of surfactant/oil/water ratios for each type of essential oil microemulsion.Finally,the physical and chemical properties as well as the rheological characteristics of the obtained microemulsions were characterized.The results showed that the HLB values of the LCO On,Onl,O75,O85,O37,O1#,O2#,and one type of borneol essential oil Ol ranged from 11 to 16.Tween 20 and soybean lecithin were suitable surfactants.Each component was stirred for 20 min,heated at 80℃ for 5 min,and cooled in an ice water bath to prepare a stable microemulsion of seven kinds of LCO.The addition amount of soybean lecithin had a significant impact on the oil phase embedding amount and emulsion stability.Adding 3％soybean lecithin could form a uniform and stable single-phase microemulsion.If it was excessive,it would be stratified,and the resulting single-phase emulsion was isotropic under polarized light.By adding 4％Tween 80,the upper limit of oil content of the microemulsion of the essential oils On,Onl,O75,and O85 could be increased from 5％to 10％and their stability could be improved.The upper limit of oil content of the O37,O1#,O2#essential oil microemulsion was 20％.The droplet size of the seven types of LCO microemulsions was small(＜22 nm),with low dispersity(PDI＜0.3).The microemulsions were transparent and homogeneous,exhibiting low viscosity and Newtonian fluid behavior,consistent with the characteritics of microemulsions.关键词
