Embodiment 1-6

[0072] Prepare the anhydrous sunscreen gel of pure physical sunscreen of the present invention according to the formula in the following table 2, and the basic steps of the preparation method are as follows:

[0073] 1) Disperse the physical sunscreen agent in the oil, homogenize it, make it evenly dispersed without coarse particles, and obtain the sunscreen agent dispersion;

[0074] 2) adding the dispersed silicone elastomer to the sunscreen dispersion obtained in step 1), and stirring evenly;

[0075] 3) Add the selected active substance and stir evenly.

[0076] For the embodiment containing an oil phase thickener, step 2) also includes adding the dispersed oil phase thickener to the sunscreen dispersion obtained in step 1).

Abstract

The invention discloses anhydrous sunscreen gel of a pure physical sunscreen agent and a preparation method of the anhydrous sunscreen gel, the anhydrous sunscreen gel comprises the following components: 10%-50% of a physical sunscreen agent, 0.1%-5% of a dispersant, 1.0%-9.0% of an organosilicon elastomer, 0%-5% of an oil phase thickener, 40%-80% of grease and 0%-5% of an active matter, the physical sun-screening agent is nano or non-nano titanium dioxide and/or zinc oxide subjected to surface treatment. According to the present invention, the pure physical sun-screening agent is utilized to form the anhydrous sun-screening gel, and the formed gel has characteristics of excellent skin feeling, high sun-screening value and good water resistance although the pure physical sun-screening agent is the whole oil formula;

Description

technical field [0001] The invention relates to a sunscreen and a preparation method thereof, more specifically, the invention relates to a sunscreen anhydrous gel of a purely physical sunscreen and a preparation method thereof. Background technique [0002] Under the strong irradiation of ultraviolet rays, the skin is prone to inflammation, burns, and even pigmented skin cancer and other problems. In order to prevent the skin from being tanned and sunburned, in addition to using sunscreen clothing for physical shielding, you can also block or absorb ultraviolet rays by applying sunscreen products and other methods. [0003] There are several types of sunscreen products currently on the market: [0004] 1. Sunscreen oil in pure oil phase system: Most sunscreen agents are oil-soluble substances, so they can be compatible with most polar oils to form a homogeneous system. But sunscreen oil feels heavy and greasy on the skin, so it is rare in the domestic market; and this sun...
