Abstract

The invention provides transparent sunscreen oil gel and a preparation method thereof. The transparent sunscreen oil gel comprises, by mass, 28.0 to 35.0% of an organic sun-screening agent, 36.2 to 47.0% of oil, 20.0 to 30.0% of a humectant, 0.3 to 1.5% of a surfactant and the balance of deionized water. The transparent sunscreen oil gel has transparent appearance and good skin feeling and has high sunscreen indexes SPF 50+ and PA ++++.

Description

technical field [0001] The invention belongs to the field of cosmetics, and mainly relates to a transparent sunscreen gel 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 two main types of transparent sunscreen products currently on the market: [0004] 1. For sunscreens of pure oil phase system, most sunscreens are oil-soluble substances, so they can be compatible with most polar oils to form a homogeneous system. However, sunscreen oil has a heavy skin feel and is not easy to absorb, so it is rare in the domestic market; [0005] 2. Ethanol system sunscreen, ethanol has good com...
