Influence of nanoemulsions on the penetrability of resveratrol
Abstract:The main topic of the effects of additives on preparation and shea butter to its particle size nanoemulsion, including the impact of different types of oils, ionic surfactants, moisturizers and rheology modifiers. And the effects of nano-emulsion particle size effect of resveratrol in the penetration and permeability of nano-emulsions containing different levels of resveratrol. Also studied particle stability and the stability of nano-emulsions resveratrol. Experimental results show that nano-emulsion of vegetable oils affect a smaller particle size, and synthetic oils in liquid oil nanoemulsion particle size effects on small diameter solid fats increase significantly so. Anionic and cationic surface active AES 1631 enables enhanced charging system, but also to make the particle size increases. Humectant glycerol and 1,3-butanediol impact on nano-emulsion system larger particle size, but a small effect on the PDI values. Join rheology modifier makes the system size and PDI values were significantly increased. The results also show that the poor low temperature stability of nano-emulsions, but better temperature stability. Stability of resveratrol are better.With resveratrol and resveratrol nanoemulsion lotion penetrate ordinary compared to the permeability of nano-emulsion better.
Keywords: nano-emulsions; preparation method; stability; Transdermal absorption
