Abstract

The invention belongs to the field of articles used in the daily life, in particular to a method for preparing novel sun cream. The novel sun cream comprises the main components of tea polyphenol, zinc oxide, glycerol, beta-carotene, Tween-80 and vaseline. The method comprises the following steps: firstly, adding the zinc oxide into the glycerol, evenly stirring to obtain a mixture A, adding the Tween-80, the tea polyphenol and the beta-carotene into distilled water proportionally, evenly stirring to obtain a mixture B, adding the mixture B into the mixture A, then adding the vaseline, evenly stirring, emulsifying and packaging so as to obtain a product. Because the product prepared by adopting the method contains the three substances of the tea polyphenol, the zinc oxide and the beta-carotene which can effectively prohibit ultraviolet rays, the skin is effectively protected by the reflection and the absorption of the ultraviolet rays, the use effect is better, all the main raw materials of the sun cream are purely natural nutrient substances, and the invention has no stimulation to the skin, can not cause skin allergy, also has no toxic or side effect and has higher use safety.

Description

technical field [0001] The invention belongs to the field of daily necessities, and in particular relates to a preparation method of a novel sunscreen. Background technique [0002] The spectrum that the sun radiates to the ground contains ultraviolet light, visible light and infrared light. Ultraviolet light has two parts, the light with a wavelength of 290-320nm is called UVB, and the light with a wavelength of 320-400nm is called UVA. UVB can inhibit mitosis and the synthesis of deoxyribonucleic acid (DNA), ribonucleic acid (RNA), and protein, causing bond breakage of biomolecules, causing DNA mutations to induce skin cancer, stimulating the production of melanin, and causing erythema called "sunburn" reaction. The penetration of UVA on clothing and human skin is far stronger than that of medium-wave ultraviolet rays. It can reach deep in the dermis and act on the melanin in the epidermis, thereby causing skin melanin pigmentation and darkening the skin, although it wil...
