Sun protection and skin care cosmetic composite and application thereof

Abstract

The invention discloses a sun protection and skin care cosmetic composite and an application of the composite in a sun protection emulsion. The composite comprises the following components: kojic acid, a radix scutellariae extract, a grape pip extract, an aloe extract, a honeysuckle extract and a cardiospermum halicacabum extract. A natural sun protection agent of a product can alleviate radiation damage of ultraviolet rays on skin by an oxidation or radical resistance effect, so that the sun protection performance of the product is indirectly improved and a light ageing phenomenon of the skin is slowed; raw materials highly absorb the ultraviolet rays and protect against the damage caused by the ultraviolet rays, and the effective components are scientifically compatible, so that an SPF (Sun Protection Factor) value of the product is higher, and the product is endowed with a high-efficiency sun protection effect; and in addition, the stimulation on the skin is low and an oil phase with good permeability and spreadability is compatible with the sun protection agent, so that the sun protection agent is better fixed on the skin, and the acting time of the sun protection agent is longer.

Description

technical field [0001] The invention relates to the field of cosmetics, in particular to a sunscreen skin care cosmetic composition and its application. [0002] technical background [0003] Excessive ultraviolet radiation in the sun will damage the human immune system, accelerate skin aging, cause various skin diseases, and even cause skin cancer. Ultraviolet rays can penetrate the skin directly to the dermis, causing skin darkening, pigmentation and aging, and even skin cancer. UVA can also trigger free radicals and reactive oxygen species, which can indirectly affect the skin. Long-term low-dose UVA exposure can cause UVA mutations, accelerate the destruction of collagen and elastin, and cause wrinkles and loss of elasticity in the skin. UVA segment ultraviolet rays account for 96% of the ultraviolet radiation reaching the ground, and its penetration is extremely strong, 35% to 50% can reach the dermis, causing damage to the cellulose in the dermis, such as collagen fib...

Problems solved by technology

Physical sunscreens mainly rely on reflection to shield ultraviolet rays to achieve the purpose of sunscreening, while chemical sunscreens rely on absorbing ultraviolet rays, converting them into heat and releasing them to achieve the sunscreen effect, but chemical UV absorbers are chemical substances, which are stable due to light Poor, easy to oxidize and deteriorate

[0005] Chinese patent application CN104644489A discloses a sunscreen, which is mainly made of aloe, titanium dioxide, isopropyl palmitate, lanolin, olive oil, stearic acid, triethanolamine, stearyl polyoxyethylene ether phosphate, wherein, The main sunscreen is titanium dioxide. Its physical and chemical properties make it only formulated into oily ointment, so this kind of sunscreen is greasy, thick and not refreshing.
