Sunscreen composition, preparation method thereof and application of sunscreen composition

Abstract

The invention discloses a sunscreen composition, a preparation method thereof and an application of the sunscreen composition. The sunscreen composition comprises, by weight, 0.1-10 parts of diethyl-hexyl butylaminyl triazinone, 0.01-10 parts of diethylaminohydroxybenzoyl hexyl benzoate, 0.01-10 parts of diethyl hexoxyphenol methoxyphenyl triazine, 0.01-10 parts of methylene dibenzotriazolidyl tetramethyl butyl phenol, 0.001-2 parts of ectoin and 0.003-2.5 parts of emollients. The preparation method includes the steps: oil-phase mixed liquid preparation; water-phase mixed liquid preparing andmixing. The sunscreen composition can be added into a composition for directly smearing skins, the sunscreen composition can prevent harm of UVA, UVB, HEV and IRA to the skins in a broad spectrum manner, so that the skins cannot be black, red and sunburned, and accelerated ageing and water loss of the skins caused by illumination are prevented.

Description

technical field [0001] The invention relates to a sunscreen composition, a preparation method and application thereof, and belongs to the technical field of skin care additives. Background technique [0002] With the development of industrial civilization, the ozone layer has been greatly damaged, which has greatly increased the ultraviolet rays irradiated on the earth's surface and posed a serious threat to human health. 280-400nm ultraviolet rays cause skin redness and sunburn, premature aging of the skin, damage to the skin barrier, and abnormalities in various physical and chemical indicators of the skin, such as reduced skin moisture, dryness, some inflammatory reactions, and atopic dermatitis , Contact dermatitis, abnormal deposition of melanin in the skin, dull skin, loss of skin elastin and collagen, and eventually pigmentation, erythema, inflammatory reaction, abnormal keratinization and aging of the skin surface. [0003] Studies have found that in addition to ult...

AI Technical Summary

Problems solved by technology

[0006] 1. The safety of sunscreens: Among the sunscreens approved by the governments of various countries, many sunscreens have been found to have photoinstability during application research, and photolysis products are likely to cause skin irritation and phototoxicity. It is impossible to make a comprehensive evaluation through SPF and PA value. Under the pressure of formula cost, some sunscreen products on the market only pursue high SPF and PA value, without considering the safety of sunscreen itself and the compatibility of sunscreens , there is a certain risk of irritation and phototoxicity to the skin;

[0007] 2. Intrinsic damage of ultraviolet rays to the skin: No matter how high the SPF and PA value are, they cannot completely prevent harmful UV rays from entering the skin, and the unblocked ultraviolet rays will still cause chronic damage to skin cells, which will increase cell oxidative stress and pigmentation. Calm, destroy collagen, accelerate aging

At present, most of the sunscreen products on the market are pursuing the sunscreen effect of high SPF and PA value, without considering the damage caused by unblocked ultraviolet rays entering the skin;

[0008] 3. At present, sunscreen technology only focuses on the protection of ultraviolet rays, and does not protect against other harmful rays in natural light, such as blue light HEV and infrared IRA, which cannot give consumers a full-band protection effect;
