Abstract

The invention provides water-soluble zinc oxide dispersion slurry. The slurry comprises, by weight, 10-90 parts of zinc oxide, 1-20 parts of a dispersing agent, 10-60 parts of a carrier and 0.1-5 parts of a preservative. The dispersing agent is one of potassium cetyl phosphate and disodium sulfosuccinate monostearate. The water-soluble zinc oxide dispersion slurry has the advantages of being highin covering power, stable in performance in a formula, great in compatibility, convenient to use, safe, free of dust pollutants and the like. At the same time, the dispersion slurry can be directly added into an aqueous phase and mutually matched with a chemical sun-screening agent in an oil phase, so that the sun protection factor of a product is greatly increased.

Description

technical field [0001] The invention belongs to the technical field of cosmetics, in particular to a water-soluble zinc oxide dispersion slurry. Background technique [0002] Zinc oxide is the second largest white pigment after titanium dioxide. It has mild drying and disinfecting effects on the skin, and has good covering power. It is widely used in cosmetics and pharmaceutical industries. Cosmetics, high-purity ultra-fine zinc oxide and surface-treated zinc oxide, small particle size, transparent, excellent coverage, good skin adhesion, smooth skin feeling, is a commonly used white in cosmetics pigment. Zinc oxide is also the sunscreen agent with the widest coverage on the market. It evenly covers the ultraviolet rays from 290nm to 380nm, and can protect all UVB and UVA bands. Therefore, it is used as a physical sunscreen in various sunscreen products. Moreover, zinc oxide has very low skin irritation and can be safely used in infant and child products. The sun protect...
