Description

[0001] This application is a divisional application of Chinese patent application No. 201880082393.1, filed on December 17, 2018, entitled “Partial Composition”. Technical Field

[0002] This invention relates to a topical composition comprising panthenol, a polysiloxane-based ultraviolet filter, and a micronized ultraviolet filter in a specific ratio. Background Technology

[0003] Sunscreen products have evolved significantly over the years. Early formulations aimed to protect users from UV-B radiation, as UV-B rays were once considered the leading cause of wrinkles, skin diseases, and skin cancer. However, recent research has shown that UV-A radiation plays an equal or even greater role in sun damage and the development of skin diseases such as lupus and melanoma and non-melanoma skin cancer. Therefore, the current focus is on eliminating as much UVA (320-400 nm) and / or UVB (280-320 nm) light as possible. Consequently, there is a growing demand for sunscreens that offer high SPF (Sun Protection Factor) and high UVA protection while remaining photostable.

[0004] In addition, modern sunscreens require skin-friendly preservatives or preservative enhancers, which can be alternatives to traditional preservatives. Another requirement for sunscreens is improved moisturizing properties and prevention or reduction of skin irritation.

[0005] However, sunscreen products often contain a lot of fats and oils, which, when applied to the skin, especially the fingers, can transfer to surfaces, particularly glass surfaces such as touchscreens, resulting in an oily residue that is highly undesirable to the end consumer. Summary of the Invention
