Sun protection composition and cosmetics prepared from sun protection composition

Abstract

The invention relates to the technical field of cosmetics, in particular to a sun protection composition and cosmetics prepared from the sun protection composition. By compounding components of zinc oxide, ethyl hexyl methoxycinnamate, titanium dioxide and the like, the obtained sun protection composition can have a good sun protection effect, the sun protection effect is remarkably superior to that of one component which is independently used or a formula-lack composition, and the sun protection effect verifies that the compounding of all the components has a good synergistic effect. Detection shows that SPE (Sun Protection Factor) value of the cosmetics prepared from the sun protection composition provided by the invention can be up to 52, and PFA (Protection Factor of UVA (Ultraviolet A)) value can be up to 18. The cosmetics have a good waterproof function, the SPF before a bath is 52, and the SPF value after the bath is 25.

Description

technical field [0001] The invention relates to the technical field of cosmetics, in particular to a sunscreen composition and the cosmetics prepared therefrom. Background technique [0002] Ultraviolet rays in the sun are one of the main causes of human skin aging. Its direct exposure to the skin can cause a series of skin problems such as skin erythema, burns, blackening, dermatitis and even skin cancer. Long-term scientific research has proved that ultraviolet rays can change the structure or function of individual cell components. When the skin is exposed to excessive ultraviolet rays, it will damage the epidermal cells; activate tyrosinase, accelerate pigment synthesis, destroy the moisturizing function of the skin, and make the skin become dull. If it is too dry, the elastic fibers in the dermis will be damaged, resulting in fine lines. Under strong exposure, it can also cause skin inflammation and burns. When there are abnormalities, it will become pigmented skin ca...

Problems solved by technology

However, investigations and studies have shown that poor permeability of UV shielding agents can easily block pores and cause skin diseases when the secretion of sweat glands is seriously affected; UV absorbers are irritating to the skin and may cause side effects such as inflammation and allergies. With high oil and water absorption characteristics, it is easy to cause dry and peeling skin

However, the sunscreen function of natural plant-derived sunscreens is relatively weak, and it is difficult to completely replace UV absorbers or UV shielding agents.
