Abstract

The invention discloses a sunscreen composition containing layered composite metal hydroxide and a preparation method thereof. The composition comprises the following components in parts by weight: 0.5-10 parts of layered composite metal hydroxide, 5-8 parts of ethylhexyl methoxycinnamate, 1-2 parts of butyl methoxyl dibenzoylmethane, 1-3 parts of benzophenone-3 and 0-1 part of bis-ethylhexyloxyphenol methoxyphenyl triazine, wherein the layered composite metal hydroxide material is safe, high in light stability and good in compatibility with other components, and the compatibility with other components in cosmetics is increased; the ethylhexyl methoxycinnamate and the benzophenone-3 absorb ultraviolet rays of a UVB wave band mainly, the butyl methoxyl dibenzoylmethane absorbs ultraviolet rays of a UVA wave band mainly, and the bis-ethylhexyloxyphenol methoxyphenyl triazine is a broad-spectrum UV absorbent; the layered composite metal hydroxide reaches the effect of physical screening through scattering and diffuse reflection of UV light, and realizes synergistic interaction with other organic ultraviolet absorbent with each other, so that the sunscreen range and sunscreen degree can be obviously promoted.

Description

technical field [0001] The invention belongs to the technical field of care product materials, and in particular provides a sunscreen composition containing layered composite hydroxide and a preparation method thereof, which are mainly used in the field of sunscreen cosmetics. Background technique [0002] The earth on which human beings live, due to the protection of the atmospheric ozone layer, blocks 99% of the ultraviolet radiation in the sun, so that all creatures on the earth are protected from strong ultraviolet rays. However, 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. The damage of UV light to epidermal cells is divided into two types: direct and indirect. UVC (220-280nm), UVB (280-320nm), and some UVA (320-400nm) can directly damage epidermal cell DNA, while most of UVA can directly reach the s...
