Embodiment 1

[0046] Example 1: Preparation of a dissolving system comprising isopropyl lauroyl sarcosinate, ethylhexyl triazone and ethanol

[0047] Weigh 5 parts by weight of isopropyl lauroyl sarcosinate and 1 part by weight of ethylhexyl triazone, stir and heat to 80° C. until completely dissolved, and keep stirring for 10 minutes. Cool to room temperature, add 94 parts by weight of alcohol, stir evenly, and stir for 10 minutes, then carry out follow-up stability inspection experiments. When observing stability, the sample needs to be returned to room temperature in advance before observation can be performed.

Embodiment 2

[0048] Embodiment 2: Preparation comprises the dissolving system of isononyl isononanoate, ethylhexyl triazone and ethanol

[0049] Weigh 5 parts by weight of isononyl isononanoate and 1 part by weight of ethylhexyl triazone, stir and heat to 80° C. until completely dissolved, and keep stirring for 10 minutes. Cool to room temperature, add 94 parts by weight of alcohol, stir evenly, and stir for 10 minutes, then carry out follow-up stability inspection experiments. When observing stability, the sample needs to be returned to room temperature in advance before observation can be performed.

Embodiment 3

[0050] Example 3: Preparation of a dissolving system comprising caprylic capric triglyceride, ethylhexyl triazone and ethanol

[0051] Weigh 5 parts by weight of caprylic triglyceride and 1 part by weight of ethylhexyl triazone, stir and heat to 80° C. until completely dissolved, and keep stirring for 10 minutes. Cool to room temperature, add 94 parts by weight of alcohol, stir evenly, and stir for 10 minutes, then carry out follow-up stability inspection experiments. When observing stability, the sample needs to be returned to room temperature in advance before observation can be performed.

Abstract

The invention discloses a sun-screening agent composition and an application thereof in cosmetics. The sun-screening agent composition contains isopropyl lauroyl sarcosinate and ethylhexyl triazone. The isopropyl lauroyl sarcosinate can efficiently dissolve the ethylhexyl triazone, improves the stability of the ethylhexyl triazone in the formula, and is conducive to development of more effective sun-screen products. In a preferred embodiment, the weight ratio of the isopropyl lauroyl sarcosinate and the ethylhexyl triazone in the sun-screening agent composition is at least 4:1.

Description

technical field [0001] The invention relates to the field of cosmetics, in particular to a cosmetic composition with sunscreen capability. Background technique [0002] With the development of medicine, a large number of experimental data prove that ultraviolet rays can damage our skin, accelerate the aging of our skin, and increase the probability of skin cancer. Therefore, today's consumers are very concerned about the sun's damage to the skin. Cosmetics with sun protection index can effectively resist ultraviolet rays and prevent the skin from being damaged by excessive ultraviolet rays. It is a major choice for consumers to prevent ultraviolet rays. [0003] Compared with ordinary cosmetics, the biggest feature of sunscreen products is that the products have the effect of resisting ultraviolet rays. According to the formula, the main reason for resisting ultraviolet rays is due to the addition of sunscreen agents in the formula. Sunscreens are substances added to suns...
