Abstract:

Alpinia oxyphylla Miq. extract is a kind of natural cosmetic raw material, which can be used as plant functional oil. In order to obtain a stable O/W microemulsion of Alpinia oxyphylla Miq. essential oil(AOEO), the O/W microemulsion containing AOEO was constructed by pseudo ternary phase diagram method. The effects of surfactants, cosurfactants, Km (mass ratio of surfactant to cosurfactant), and their different components and ratios on the area of the microemulsion were investigated. The particle size, morphology, conductivity, water solubility and stability of the microemulsion were measured, and its characterization and physicochemical properties were discussed. The results show that the optimal formula of O/W microemulsion of AOEO is obtained as follows: m(castor oil polyoxyethylene ether 40 (EL-40)) ∶m(1,2-propylene glycol) ∶m(AOEO)=10.5∶3.5∶6, the transition point of O/W microemulsion is 60% (mass fraction). The average particle size of the O/W microemulsion is (26.580±0.133) nm, the polydispersion index (PDI) is 0.226±0.010, and the microemulsion is slightly spherical or quasi-spherical, regular, and without adhering edges under transmission electron microscopy (TEM) and digital biological microscopy (DBM). The microemulsion has good water solubility, centrifugal stability, thermal stability and low temperature storage stability. The results show that the nano-coating of AOEO can be realized by using microemulsion as carrier, which provides reference for the development and application of AOEO in daily chemical field.
