Abstract

The invention provides a sunscreen agent containing paeonol and a preparation method thereof. According to the method, an oil phase and a water phase are homogenized and emulsified according to the mass ratio of 1:(1-1.2), then inulin accounting for 20-30% of the weight of the water phase is added, and high-speed shearing is carried out to obtain the gel-like sunscreen agent. The oil phase comprises the paeonol modified by organic silicon and hemp essential oil, and the water phase comprises small-molecular fucoidan, chitosan oligosaccharide and the like. The obtained sunscreen agent has an excellent sunscreen effect on UVA and UVB components of ultraviolet rays and a good moisturizing effect.

Description

technical field [0001] The invention relates to the technical field of fine chemicals, in particular to a sunscreen containing paeonol and a preparation method thereof. Background technique [0002] With the development of the economy and the improvement of people's living standards, leisure, tourism and vacation have become new ways of life and consumption. When enjoying the beach, sunshine, outdoor hiking and other activities, it is inevitable to face the damage of ultraviolet rays to the skin, and sunscreen is one of the effective means to block the damage of ultraviolet rays. [0003] There are three types of ultraviolet rays: long-wave UVA (wavelength 320-400nm), mainly to darken the skin, activate tyrosinase, accelerate the production of melanin, and at the same time destroy the collagen in the dermis, leading to premature aging and relaxation of the skin; Wave UVB (wavelength 280-320nm) mainly causes skin burns and redness, which can cause changes in skin epidermal c...
