Abstract

The invention relates to a sunscreen lotion and a preparation method thereof. The sunscreen lotion contains the following components: a first sunscreen composition, a second sunscreen composition, isotriacontane, glycerol, isopropyl myristate, ethanol, an essence, methyl p-hydroxybenzoate, propyl p-hydroxybenzoate and water. According to the preparation method, sunscreen components in the sunscreen lotion are effectively isolated from outside by virtue of a nano-microencapsulation technique. Compared with the prior art, the sunscreen lotion has the advantages that a preparation process is simple, the prepared sunscreen lotion has durable and effective sunscreen capacity, and the microencapsulated chemical sunscreen components only stay on the surface of the surface, have low stimulation to skin and are safe and effective, so that the problem that the sunscreen lotion is easily dissolved by sweat, rainwater, seawater and the like so as to fall after smearing is solved.

Description

technical field [0001] The invention relates to the technical field of sun protection, in particular to a sun protection liquid and a preparation method thereof. Background technique [0002] The damage of sunlight to human skin mainly comes from ultraviolet A (ie UVA) and ultraviolet B (ie UVB). UVA acts on the deep layer of the skin and acts slowly, but it can cause one-time blackening. UVB acts on the surface layer of the skin to stimulate keratinocytes, dilate blood vessels, increase blood flow, and make the skin red until it turns brown. UVA and UVB will cause sunburn, peeling, tanning and other after-sun phenomena on the skin, which will cause premature aging of the skin and cause some irreparable damage to the skin. If it is affected by UVA and UVB for a long time, it may also cause skin cancer. [0003] At present, sunscreen measures against ultraviolet rays mainly include physical sunscreen and chemical sunscreen. Physical sunscreen refers to the use of substances ...
