Abstract:

In order to enhance the development and application of Camellia oleifera seed oil (CSO) in the field of cosmetics, the study utilizes CSO as the cosmetic base oil and combines it with ceramide (Cer). High-pressure homogenization was employed to prepare and optimize the best formula and conditions for the CSO-Cer nanoemulsion. The results show that under the conditions of homogenization pressure at 100 MPa, 7 cycles, a CSO mass fraction of 15%, a Cer addition of 1%, a hydrogenated lecithin mass fraction of 4%, a cholesterol mass fraction of 0.2%, and a glycerol mass fraction of 25%, a nanoemulsion with optimal particle size and stability is obtained. This emulsion has a particle size of 124.7 nm, a polydispersity index of 0.108, and a Zeta potential of -55.7 mV. Further testing reveals that the CSO-Cer nano-emulsion exhibits excellent moisturizing and transdermal properties. Consequently, the CSO-based CSO-Cer nanoemulsion is a potential new type of functional cosmetic emulsion, providing significant technical reference for the subsequent application of CSO in the field of cosmetics.
