Abstract

The invention discloses a plant skin whitening preparation. The plant skin whitening preparation is prepared by a complex coacervation method and specially prepared by mixing water and chitosan, stirring, adjusting the pH value to 2.5-3.5 with glacial acetic acid, completely dissolving the chitosan to obtain a water solution; uniformly mixing luteolin, a mulberry bark extract, licoflavone, tanshinone and vitamin E, adding an emulsifier, stirring uniformly, homogenizing, adding the chitosan water solution to obtain a solution I; adding carboxymethyl chitosan into water, stirring and dissolving to obtain a solution II; while stirring at the constant temperature of 40-60 DEG C, slowly adding the solution I into the solution II, adjusting the pH value of the solution to 5.0-6.5, and then further stirring for 30-45min; cooling the complex coacervation liquid, then adjusting the pH value to 6.5-8.0, adding a curing agent, moving to a water bath at 40-50 DEG C for curing reaction to obtain a microcapsule emulsion; and centrifuging the microcapsule emulsion, washing the precipitate with purified water for 1-3 times, dispersing in 20-30 parts by mass of purified water, and carrying out spray drying to obtain the plant skin whitening preparation. The plant skin whitening preparation has the functions of resisting irritability, whitening and promoting blood circulation.

Description

technical field [0001] The invention relates to the technical field of daily chemicals, in particular to a plant whitening preparation, its preparation method and its application in whitening cosmetics. Background technique [0002] Smooth, fair and ruddy skin has always been the beauty trend pursued by oriental women, hoping to achieve the effect of "skin like snow, firm like fat". In the past, whitening products used by people often contained physical shielding materials such as titanium dioxide, which can temporarily whiten and modify their skin. With the advancement of science and technology, the whitening that women pursue today has deeper physiological needs. They pursue the overall fairness of the skin, such as the desalination and removal of stains and the prevention of pigmentation. At the same time, whitening products are required to have safe, mild and efficient performance. [0003] The whitening cosmetics market is becoming increasingly active, and product sal...
