Abstract

The invention discloses a microcapsule with an effect of after-sun repairing and a sunscreen cream containing the microcapsule. The capsule wall material of the microcapsule comprises maltodextrin, Arabic gum and hydroxyethyl cellulose; the capsule core material of the microcapsule comprises coconut oil, sea buckthron oil, jojoba wax, squalane, vitamin E, witch hazel alcohol extract, purslane alcohol extract, paeoniflorin, green tea alcohol extract, L-cysteine and span; and the sunscreen cream is prepared from the microcapsule with the after-sun repairing effect, coconut oil, lanolin, ethanol, zinc oxide, titanium dioxide, iso-octyl p-methoxycinnamate, butyl methoxydibenzoylmethane, 2-ethylhexyl 2-cyano-3,3-diphenyl-acrylate, vitamin E, deionized water, xanthan gum and span 20. An after-sun repairing ingredient is embedded by a microcapsule technology and is added into the sunscreen cream, so that the sunscreen cream has sunscreen and after-sun repairing double functions, and adverse mutual competition caused by coexistence of the sunscreen and after-sun repairing ingredients can be effectively avoided.

Description

technical field [0001] The invention belongs to the technical field of sun protection, and in particular relates to a microcapsule with after-sun repairing effect and a sunscreen containing the microcapsule. 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.
