A kind of plant extract for whitening and moisturizing and preparation method thereof |
| abstract |
The invention discloses a plant extract for whitening and moisturizing and a preparation method thereof. In the preparation process of the plant extract for whitening and moisturizing, a multi-effect stabilizer with antibacterial, anti-oxidation and anti-ultraviolet light effects is added. agent. The multi-effect stabilizer is obtained by cycloaddition reaction of phenolic acid compound and azide carboxymethyl chitosan, and the phenolic acid compound and the azide group are formed by the method of forming a triazole ring structure with an alkynyl group and an azide group. Nitrogenated carboxymethyl chitosan binding. The preparation method of the invention has simple steps and quick operation, and has the potential of large-scale application; the invention can effectively prevent the active components of the plant extract from being putrefied, and can avoid their oxidative decomposition under the influence of environmental factors such as light. |
