Problems solved by technology

[0007] However, the use of coated SiO in sunscreen formulations 2 Pyrolytic TiO 2 The following series of problems still exist: 1. Insufficient transparency ("blush") after application to the skin, as if applied with a white film; 2. Complex dispersion system is required; Obvious thickening effect, so that the preparation has a high content of TiO 2 The dispersed phase becomes difficult; 4. The prepared sunscreen cosmetics have an unpleasant dull feeling when applied on the skin

[0064]

[0065]

[0066] Table 2 Function and source of main ingredients of sunscreen

[0067]

[0068] The dosage of glabridin in cosmetics is between 0.05-0.1%.

[0069] The additive amount of self-made sunscreen lotion in this formula is between 5-10%. After many experiments and three years of observation, it is found that more than this amount of additives will affect the spreading performance and the stability of the formula structure, while less ones cannot meet the requirements of formula design.

[0070] The amount of β-glucan additive is between 5-9%, preferably between 5-7%. After many experiments and comparative observations of 30 volunteers using 3%, 5% and 9% (10 people in each group) under relatively consistent humidity conditions...

Embodiment 2

[0076] Embodiment 2 The preparation technology of sunscreen of the present invention

[0077] The preparation process of sunscreen of the present invention is as follows:

[0078] 1. Add phase A except the essence, weigh it, pour it into the emulsification pot and mix evenly, add phase B, stir for 5 minutes, control the speed of the emulsification pot at 900 rpm, then homogenize for 2 minutes, add the essence, and mix evenly;

[0079] 2. Weigh the water and put it into the water pot, add the remaining raw materials in phase C to form the water phase, raise the temperature to 90°C, keep it warm for 30 minutes (high temperature sterilization), cool down to below 40°C, add phase D, and mix well;

[0080] 3. Adjust the rotation speed of the emulsification pot to 1000 rpm, slowly introduce the water phase into the emulsification pot, and control the process within 30 minutes. After the completion, add the E-phase raw materials and continue stirring until uniform. After uniformity, ...

Abstract

The invention provides a sunscreen lotion, which comprises: 3.5wt% of tetraethyl orthosilicate TEOS; 3wt% of ethanol absolute; 1wt% of glacial acetic acid; 6wt% of butyl titanate; 20-25wt% of nano-TiO2; 25-35wt% of micron-SiO2; and the balance deionized water. The sunscreen lotion is a titanium dioxide wrapped silicon dioxide composite particle. The invention also provides a SiO2 / TiO2 composite particle and a preparation method of modified SiO2 / TiO2 particle. The invention also provides a sunscreen cream containing the sunscreen lotion. The sunscreen lotion and the sunscreen cream provided by the invention have high ultraviolet absorption ability, good application effect, and anti-aging and whitening effect, and are easy to prepare.

Description

technical field [0001] The invention relates to beauty cosmetics, in particular to a sunscreen liquid and a sunscreen. Background technique [0002] Ultraviolet radiation in sunlight is a light wave that is harmful to the human body. Under normal circumstances, due to the blocking of the ozone layer in the atmosphere, the ultraviolet radiation that can reach the ground is very small, so it does not cause much impact. However, if you travel, work or sunbathe in the open air for a long time, you may receive too much ultraviolet radiation, which will cause erythema on the skin, accelerate skin aging, and even lead to the occurrence of skin cancer. In recent years, due to the continuous expansion of the ozone layer, the harm of ultraviolet radiation cannot be underestimated. There are three sections in the ultraviolet spectrum: UVA (320-400nm), UVB (280-320nm) and UVC (less than 280nm), among which UVA and UVB ultraviolet rays are mainly harmful to the human body. UVA can caus...
