[0032] It consists of the following components in terms of mass percentage: 0.5% cedar wood essential oil with a concentration of 1 wt%, 2% propylene glycol, 2% glycerin, 0.1% hyaluronic acid, 0.5% sodium hydroxymethylglycinate, and 0.1 wt% Uruguay tea Extract 2%, Lactic Acid 0.25% and Water 92.65%.
[0033] Wherein, the preparation method of cedar wood essential oil comprises the steps:
[0034] (1) Take 500g of dry cedar wood and grind it, transfer it to a 5L fermenter with 1500g of distilled water, add 0.5% beef extract, 1% peptone and 0.5% sodium chloride, and adjust the pH to 4.5 with 1mol / L phosphate buffer , naturally fermented for 36 hours, and then high-temperature inactivated strains;
[0035] (2) Fully mix the product obtained in step (1) with 1.5 g of compound enzymolysis solution, and enzymolyze it for 30 minutes at 42°C; the compound enzymolysis solution is cell...
