Description

Technical Field

[0001] The invention relates to a mild sunscreen mousse and a preparation method thereof, and relates to A61K, in particular to the field of makeup preparations. Background Art

[0002] Sunlight irradiation has certain damage to human skin, causing the skin to become red and peel, and also causing the skin to tan, even causing the skin to become loose and aging. Ultraviolet rays penetrate deep into the skin, which may cause sun spots on the skin and even skin cancer. Therefore, using sunscreen products to resist ultraviolet rays is an important means of protecting the skin. Existing smearable sunscreens and sunscreens will cause the skin to be stuffy and greasy after use, especially for female users. Spray-type sunscreen products are light in texture and have a clear feel when used. However, if nano-silicon dioxide is added to the sunscreen spray, there is a risk of inhalation, and the safety of use is poor. Therefore, it is crucial to develop a sunscreen product that has a clear skin feel and is easy to use.

[0003] Chinese invention patent CN202311274086.2 discloses a sunscreen composition with foaming function, its preparation method and application, which uses triethanolamine salt formed by the reaction of triethanolamine and fatty acid as a foaming ingredient. In the presence of a propellant, it can show rich foaming performance to form a dense foam mousse, which can resist the inflammatory response, pigmentation, and collagen degradation caused by UV stimulation. However, the amount of propellant used is small, and the product cannot be completely launched in the later stage, resulting in a large amount of waste. Chinese invention patent CN202310144483.1 discloses a sunscreen composition, its preparation method and application, with a high sun protection index. It is prepared into a sunscreen mousse, which is in the form of a mass of fine foam after spraying. The foam is not easy to dissipate and has good safety. However, the sunscreen mousse takes a long time to melt and is inconvenient to use. Summary of the invention
