Abstract

The invention relates to a toner containing zinc oxide and salicylic acid, comprising the components of 0.1-5% of zinc oxide the grain diameter of which is 0.05-6 micron, 0.001-2% of bentonite, 0.01-0.1% of isopropyl methylphenol, 0.2-2% of salicylic acid, 0.01-1% of light protective agent of Parsolguard, auxiliary materials which are acceptable in the toner field and the balance of water by weight proportion. The invention also relates to the preparation method of the toner and the application of zinc oxide and salicylic acid in preparing a toner. Mentholatum develops the novel toner after years of study. The toner contains mild zinc oxide powder and has the effects of oil control, astringing, diminishing inflammation and the like. Meantime, the toner contains the bactericide of salicylic acid and isopropyl methylphenol and a small additive amount can take the effects of removing acne and sterilization. In addition, the toner disclosed by the invention contains bentonite, thus the toner has good stability. The zinc oxide is not prone to aggregation even if the zinc oxide stands for years in the toner.

Description

technical field [0001] The invention relates to the field of cosmetics. Specifically, the invention relates to a toner containing zinc oxide and salicylic acid, a preparation method thereof, and an application of the zinc oxide and salicylic acid in preparing the toner. Background technique [0002] Zinc oxide is an amphoteric compound, which has a very wide range of uses in rubber, textile industry, electronics industry, cosmetics industry, ink, paint and coatings and other industries. The ultrafine zinc oxide has a strong ability to absorb ultraviolet light, and has better ultraviolet absorption ability and transparency than the existing ultrafine titanium dioxide pigment. Therefore, zinc oxide is currently widely used in sunscreen compositions to enhance the sunscreen effect. Zinc oxide particles have excellent properties such as anti-toxicity, control of microbial fungi and absorption of ultraviolet light, so they have special uses in rubber, coatings, ceramics, chemica...
