Embodiment 1

[0014] The production process of the Polygonum sorrel extract is as follows: 1) Pulverize the Polygonum sorrel powder in a pulverizer to obtain Polygonum sorrel powder after vacuum drying, and place the Polygonum sorrel powder in an extraction kettle for supercritical extraction, 2 ) Use supercritical CO2 as a solvent, and ethanol with a concentration of 65% as an entrainer; 3) Adjust the extraction kettle to control the extraction pressure at 25-30MPa, the temperature at 45°C, the CO2 flow rate at 9L / h, and the extraction time at 2h, get Polygonum sorrel extract.

[0015] According to the weight ratio: neohesperidin dihydrochalcone 0.5%, Polygonum sorrel extract 4%, glycerin 5%, propylene glycol 3%, allantoin 2%, hydroxyethyl cellulose 0.8%, sorbic acid 2%, 0.8% of sodium hyaluronate and the balance of water constitute.

Embodiment 2

[0017] The same manufacturing process as in Example 1, the difference is: 0.5% neohesperidin dihydrochalcone, 5% Polygonum sorrel extract, 5% glycerin, 3% propylene glycol, 2% allantoin, hydroxyethyl 0.8% of cellulose, 2% of sorbet, 0.8% of sodium hyaluronate and the balance of water constitute.

Embodiment 4

[0025] The same manufacturing process as in Example 1, the difference is: 0.5% neohesperidin dihydrochalcone, 5% Ginkgo biloba extract, 5% glycerin, 3% propylene glycol, 2% allantoin, hydroxyethyl cellulose 0.8%, Sorbet 2%, sodium hyaluronate 0.8%, and the balance of water constitute.

Abstract

The invention discloses a Persicaria lapathifolia whitening lotion. The effective components of the lotion comprise neohesperidin dihydrochalcone, Persicaria lapathifolia extract and matrixes, and the matrixes are magnesium vitamin E phosphate, polyglyceryl-3 diisostearate, glycolic acid, linseed oil and hyaluronic acid respectively. The Persicaria lapathifolia extract is adopted as a main raw material, and neohesperidin dihydrochalcone and some matrixes are added, so the lotion has low price; and a mixture of the Persicaria lapathifolia extract and a small amount of neohesperidin dihydrochalcone has a very good synergistic effect on whitening, and greatly improves the whitening effect especially when a weight ratio of the Persicaria lapathifolia extract to neohesperidin dihydrochalcone is 8:1 to 10:1.
