Abstract

The invention discloses a preparation method of refreshing sunscreen lotion. The preparation method includes the following steps: (1) weighing 10-15 parts by weight of caprylic / capric triglyceride and5-8 parts by weight of octyl methoxycinnamate to put into a reaction kettle, heating the reaction kettle to 100-120 DEG C, and performing stirring to make mixture fully mixed; (2) weighing 10-20 parts by weight of titanium dioxide, 5-10 parts by weight of titanium dioxide, and 3-6 parts by weight of zinc oxide to dissolve in 50-60 parts by weight of water, performing stirring and dissolving, pouring an obtained solution into the reaction kettle, adding 3-8 parts of butyl methoxydibenzoylmethane, cooling the mixture to 70-80 DEG C, and performing stirring for 10-20 min at a maintained temperature; and (3) cooling the reaction kettle to below 40 DEG C, adding 0.5-2 parts by weight of a thickening agent and 0.3-1 part by weight of a preservative so that sunscreen lotion can be obtained through stirring, dissolving and homogeneity. The prepared sunscreen lotion is an oil-in-water sunscreen product; as the caprylic / capric triglyceride is taken as base grease, the obtained sunscreen lotionis refreshing, not greasy and excellent in sunscreen effect, so that multiple smearing is not needed; and the sunscreen lotion can maintain more than 5-6 h outdoors.

Description

technical field [0001] The invention relates to a preparation method of sunscreen milk, in particular to a preparation method of refreshing sunscreen milk. Background technique [0002] The ultraviolet spectrum in sunlight is in the wavelength range of 100-400nm, which can be divided into three bands, namely, short-wave ultraviolet (UVC) with a wavelength of 100-290nm, medium-wave ultraviolet (UVB) with a wavelength of 290-320nm, and ultraviolet rays with a wavelength of 320-290nm. 400nm long-wave ultraviolet (UVA). Different wavelengths of ultraviolet rays penetrate the skin at different depths. UVC is reflected and absorbed by the stratum corneum, and only a small part penetrates to the superficial layer of the epidermis. However, when UVC passes through the atmosphere, most of it is absorbed by the ozone layer and cannot reach the surface of the earth, so it will basically not cause harm to human skin. Most of UVB is absorbed by the epidermis, and a small part reaches ...
