Description

technical field [0001] The invention relates to a cosmetic and a preparation method thereof, more specifically to a sunscreen milk containing natural plant sunscreen ingredients and a preparation method thereof. Background technique [0002] Direct exposure of ultraviolet rays in the sun to the skin can cause damage to the skin in varying degrees, such as erythema, burns, dermatitis, and even skin cancer in severe cases. Ultraviolet rays are one of the main causes of people's skin aging, so people pay more and more attention to the development of sunscreen to prevent the damage caused by ultraviolet rays in the sun to the skin. At present, most sunscreens in cosmetics use chemically synthesized UV absorbers, such as p-aminobenzoic acid and its esters (PABA), anthranilate, salicylic acid ester p-methoxy carnitate, Benzophenone and its derivatives, methane derivatives, etc. The above-mentioned chemically synthesized sunscreens are all irritating to the skin, and there are ce...
