Abstract

The invention discloses a preparation method of a sunscreen cream containing after-sun repairing microcapsules. The preparation method comprises the following steps: firstly, preparing the after-sun repairing microcapsules by taking maltodextrin, arabic gum, hydroxyethyl cellulose, coconut oil, sea buckthron oil, jojoba wax, squalane, vitamin E, a hamamelis alcohol extract, a purslane alcohol extract, paeoniflorin, a green tea alcohol extract, L-cysteine and span-80 as raw material; and then taking the microcapsules together with coconut oil, lanolin, ethanol, zinc oxide, titanium dioxide, octyl p-methoxycinnamate, butyl methoxy-dibenzoyl methane, 2-cyano-3,3-diphenyl ethylhexyl acrylate, vitamin E, deionized water, xanthan gum and span-20 as raw materials to prepare the sunscreen cream. According to the preparation method disclosed by the invention, after-sun repairing components are embedded by virtue of a microcapsule technology and then are added into the sunscreen cream to ensure that the sunscreen cream gives play to two effects of sun-screening and after-sun repairing, thereby effectively avoiding adverse interactive competition caused by coexistence of the two effects.

Description

technical field [0001] The invention belongs to the technical field of sun protection, and in particular relates to a preparation method of a sunscreen containing microcapsules with after-sun repair function. Background technique [0002] UVA and UVB in the sun can penetrate the dermis, causing sunburn, peeling, tanning and other after-sun phenomena on the skin, which in turn causes the skin to age prematurely and cause some irreparable damage to the skin. If you are affected by UVA and UVB for a long time , may also cause skin cancer. [0003] In order to prevent the skin from being tanned and sunburned, sunscreen products with added sunscreen ingredients have emerged as the times require. However, even if you use sunscreen for strict protection, it is impossible to completely isolate the damage caused by ultraviolet rays. After-sun repair is an important repair measure after long-term sun exposure, but only repairing in a short period of time after sun exposure can prot...
