Embodiment 1

[0091] A photochromic sunscreen particle includes a photochromic material and an embedding agent. The specific production method of the photochromic sunscreen particle is: dissolving 2g of photochromic material in 5.2g of tetraethoxysilane and cutting at high speed. The mixed solution is prepared under the action of emulsification and dispersion. The above-mentioned mixed solution is emulsified with 24g of an aqueous solution containing 1% cetyltrimethoxyammonium chloride, and the obtained emulsion is poured into 35g of hydroxide with adjusted pH 11.3 In a reactor with sodium aqueous solution, the reaction is stirred at room temperature for 24 hours, the product is centrifuged, the product is washed with deionized water, and the photochromic sunscreen particles are obtained by spray drying.

Embodiment 2

[0093] Example 2: Sunscreen

[0094] The photochromic sunscreen particles prepared in Example 1 were added to the sunscreen base at a weight ratio of 5%, fully stirred and mixed, and obtained by following the existing sunscreen manufacturing and storage methods.

[0095] When using it, apply sunscreen to exposed areas such as face and arms.

[0096] The photochromic material is selected and can be converted into pink under sunlight, so that the human skin presents a more healthy and beautiful color.

Embodiment 3

[0097] Example 3: Oil paint for body painting

[0098] The photochromic sunscreen particles prepared in Example 1 were added to the adjusted matrix containing different colors according to the weight ratio of 8%, and the mixture was fully stirred and mixed to obtain.

[0099] The oil paint can not only play a strong role in sun protection, but also can change colors with the intensity of sunlight to form novel and fantastic effects on the surface of the human body.

[0100] The oil paint of the invention has strong waterproof performance and high fatigue resistance.

Abstract

The invention provides a photochromic sunblock particle, a human body surface coating object containing photochromic sunblock particles, and application of the coating object in skin sunblock, body painting and a field hidden material. A photochromic material is added into the human body surface coating object and serves as an ultraviolet absorber, the absorption wavelength is between 280 nm and 400 nm and is just in the wavelength range of UVA (ultraviolet a) and UVB (ultraviolet b) radiating to the ground, the absorption efficiency is high, and the ultraviolet protection effect is improved; the photochromic material is stable in performance, long in service life and good in hot and cold resistance, and the fatigue endurance can reach more than 10,000 times; the surface coating object can be changed into various beautiful and bright colors while absorbing ultraviolet light, can change the colors when applied to a human body and irradiated under sunshine, and can be used for body painting, the field hidden material and the like due to the characteristic; and besides, the ultraviolet intensity of sunlight can be evaluated through observation of the color change condition and the color degree, and a user can be reminded of certain ultraviolet protection.

Description

Technical field [0001] The invention relates to the field of cosmetics, in particular to a body surface coating. Background technique [0002] Ultraviolet rays are non-ionizing radiation in electromagnetic waves. The sun is the main source of ultraviolet rays. The wavelength range is 100-400nm. According to the wavelength, ultraviolet rays are divided into C section (UVC, 100-290nm), B section (UVB, 290-320nm) and Section A (UVA, 320-400nm), when ultraviolet rays pass through the atmosphere, the ozone molecules in the ozone layer absorb all the ultraviolet rays with a wavelength less than 290nm (section C), and also absorb a large amount of ultraviolet rays in the range of 290-320nm (section B), radiating to The surface of the ground is mainly 320-400nm (mainly UVA) solar ultraviolet rays, which will affect people and living things. [0003] However, with the increase in air pollution, the ozone layer is becoming thinner and the ultraviolet energy reaching the ground continues to ...
