Description

Sunscreen repair cosmetic composition and preparation method and application thereof

Technical Field

The invention relates to a sunscreen repair cosmetic composition, a preparation method and application thereof, and belongs to the field of cosmetics.

Background

Ultraviolet rays are the main focus of research on photoaging at the present stage, and skin becomes dry and rough, loses elasticity and luster after being damaged by irradiation. The sun Protection factor spf (sun Protection factor) value is generally used to evaluate the resistance of a sunscreen to UVB (outdoor uv light) and pa (Protection UVA) to evaluate the resistance of a sunscreen to UVA (long wave black spot effect uv light). However, it is also important to reduce the deposition of melanin on the skin during sunscreen and repair, and to replenish moisture to the skin.

However, the sunscreen cosmetics of the prior art are mostly based on protection against uv light, such as some sunscreen products with high SPF values and PA. These broad-spectrum sunscreen cosmetics, although capable of protecting the skin from ultraviolet rays to a large extent, cannot repair the sunburned skin. In addition, the damage of infrared rays to the skin is not paid enough attention, the penetrating power of heat radiation caused by the infrared rays to the skin is stronger than that of ultraviolet rays, the damage of the ultraviolet rays can be enhanced, and when the skin is irradiated by the ultraviolet rays and the infrared rays, erythema is more easily generated, and water in the skin is correspondingly lost.

Patent application document CN105193678A provides a sunscreen and after-sun repair skin care composition: the composition is composed of rhEGF, hydrolyzed soybean protein, purslane extract, schisandra extract and rhizoma kaempferiae extract, and can repair damaged skin and reduce skin damage caused by ultraviolet rays. Patent application document CN103405363A provides a sunscreen repair composition which is also capable of reducing uv damage to the skin. However, neither of the above two repairing compositions can reduce or prevent the damage of the skin by the heat radiation caused by the infrared ray.

The addition amount of the coral algae extract is 0.01-6%, preferably 2-3%, more preferably 2.5% by weight of the sunscreen and repair cosmetic composition. In the present invention, if the coral algal extract is added in an amount of less than 0.01%, the sunscreen cosmetic composition does not have an obvious barrier effect against infrared rays and heat; if the addition amount of the coral algae extract is more than 6%, the sunscreen and repairing effect of the sunscreen and repairing cosmetic composition is better, but the cost is too high to be implemented. The addition amount of the coral algae extract is 2-3%, especially 2.5%, the sun-proof repair effect and the cost performance are optimal.

In a specific embodiment, the coral algae extract can be prepared by,

step 1), soaking the crushed coral seaweed in a propylene glycol aqueous solution to obtain a soaking solution;
