A kind of production method of the cosmetic oil based on almond benevolence, belongs to cosmetics processing technique field.The present invention by almond benevolence by drying, be crushed to certain particle size；Add after ethanol and the pretreatment of ethyl acetate microwave radiation technology, supercritical CO is carried out using ethanol and ethyl acetate as entrainer 2 Extraction, pressure is extraction under the conditions of 20~30MPa, 45~50 DEG C of temperature；Then separated in knockout drum at pressure 3MPa~6MPa, 25~30 DEG C of temperature.After reclaiming ethanol and ethyl acetate through vacuum distillation, extraction oil obtains anti-oxidant almond oil by adding carnosine, Tea Polyphenols and lycopene composite antioxidant after solubilising.Extraction rate of the present invention is fast, recovery rate is high, no solvent residue, and the high quality oils water activity of acquisition is low, with anti-oxidant and vegetative cell function, and water retention property and Storage are all good, can be used as in cosmetics of super quality base starting material. |
