Natural plant sunscreen composition and preparation method thereof

Abstract

The invention relates to a natural plant sunscreen composition and a preparation method thereof. The composition comprises a phase A and a phase B, wherein the phase A comprises the following components of fat, an emulsifying agent and a chemical sunscreen agent; and the phase B comprises the following components of a solvent, a soothing agent, a plant sunscreen agent, a thickening agent and an additive, wherein the additive comprises a preservative, a pH-regulating agent and an antioxidant. The preparation method comprises the preparation steps of (1) heating the solvent, the thickening agent, the plant sunscreen agent and the soothing agent in an emulsifying pot to 75-80 DEG C, and performing stirring for dissolving; (2) heating the fat, the emulsifying agent and the chemical sunscreen agent to 75-80 DEG C, adding the heated fat, the heated emulsifying agent and the heated chemical sunscreen agent to the emulsifying pot, performing homogenizing and emulsifying, and reducing the temperature; (3) reducing the temperature to 45-50 DEG C, sequentially adding the antioxidant and the plant sunscreen agent, and continuing performing stirring to reduce the temperature; (4) reducing the temperature to 45 DEG C or below, sequentially adding the preservative and a pH-regulating agent mixture; and (5) performing examination, performing discharging and performing filling. The natural plant sunscreen composition disclosed by the invention has good sunscreen effects.

Description

technical field [0001] The invention relates to the technical field of cosmetics, in particular to a natural plant sunscreen composition and a preparation method thereof. Background technique [0002] For more than half a century, as the amount of ultraviolet radiation has been increasing along with the destruction of the ozone layer, the number of patients with solar dermatitis, skin aging and even skin cancer has increased significantly worldwide. Therefore, sun protection has been increasingly valued by the medical and cosmetic industries. However, most of the current sunscreens use chemical compounds. When the amount of such sunscreens is too much, it is easy to cause skin allergies; even titanium dioxide, which has always been considered as a safe physical sunscreen, has been reported that titanium dioxide is less than 380nm. Under the wavelength, titanium dioxide will be affected by ultraviolet rays, and the stimulated titanium dioxide will generate active oxygen free ...
