Problems solved by technology

[0004] It can be seen that the compounding of BMDM and other sunscreens is a good idea to solve its poor photostability, but there are still the following problems: ① After compounding with other sunscreens, although the SPF has increased, it is still not ideal, such as When compounded with titanium dioxide, the remaining amount of BM DM after ultraviolet irradiation can only reach 76% and 49%; ②When compounded with other sunscreens, the content of sunscreens increases, and excessive sunscreens often cause thick, whitening and other undesirable skin Sensation, irritation and potential danger

Embodiment 1

[0028] Embodiment 1, the rutile type titanium dioxide processed by mixed surfactant

[0029] Weigh 10g of rutile titanium dioxide, add deionized water, stir and disperse to obtain a titanium dioxide suspension with a mass fraction of 3%; add a mixed surfactant with a weight of 6% of titanium dioxide, stir, heat in a water bath, stand overnight, and evaporate to remove water , dried, that is. The mixed surfactant is composed of surfactant and sodium lauryl sulfate in a weight ratio of 0.02:1.

Embodiment 2

[0030] Embodiment 2, the anatase type titanium dioxide processed through mixed surfactant

[0031] For the preparation of anatase titanium dioxide treated with mixed surfactants, refer to the above-mentioned Example 1.

Embodiment 3

[0032] Embodiment 3, the titanium dioxide processed through sodium lauryl sulfate

[0033] The difference from Example 1 is that sodium lauryl sulfate is used instead of the mixed surfactant to prepare titanium dioxide treated with sodium dodecyl sulfate with two crystal structures.

Abstract

The invention relates to the technical field of cosmetics, in particular to sunscreen composition and an appellation thereof. A sunscreen is prepared from titanium dioxide and avobenzone in a weight ratio being (0.01-1):1 after being treated by a mixed surfactant which comprises surfactin and sodium dodecyl sulfate in a weight ratio being (0.01-0.05):1. The sun protection factor of a sunscreen cosmetic can reach SPF 49, and the sunscreen cosmetic has low sunscreen content and good skin feeling after use.

Description

technical field [0001] The invention relates to the technical field of cosmetics, in particular to a sunscreen composition and its application. Background technique [0002] In recent years, skin cancer has become one of the most common cancers in the world due to the increased intensity of ultraviolet radiation due to the seasonal expansion of the ozone layer hole. People's awareness of protection against photodamage caused by ultraviolet rays is increasing year by year, and the demand for sunscreen cosmetics is also increasing. In the personal care industry, sunscreen cosmetics have become the fastest growing branch in recent years. High sun protection index, broad-spectrum sun protection, strong water resistance and friction resistance, and excellent skin feel such as light and thin texture, skin-friendly, non-whitening, and non-greasy have become the development trend of this type of cosmetics. [0003] At present, butyl methoxydibenzoylmethane (BMDM, trade name: Escal...
