Problems solved by technology

[0003] When zinc oxide is used, due to its original nature of large specific surface energy, the particles are easy to agglomerate, resulting in poor dispersion in solvents, easy to cause sedimentation and poor suspension, and finally appear in non-solid products. Floating color or Instability problems such as powder settling, resulting in poor uniformity and hiding power when the product is used / smeared

Abstract

The invention discloses water-in-oil type zinc oxide dispersing paste which mainly comprises the following components in percentage by mass: (a) 5-40% of zinc oxide; (b) an oil phase consisting of one or more oil components, wherein the addition amount of the oil phase is 5-30%; (c) a mixed emulsifier consisting of one or more emulsifiers, wherein the HLB (Hydrophile-Lipophile Balance) value of the mixed emulsifier is 3-6, and the addition amount of the mixed emulsifier is 0.5-5%; (d) a mixture of one or more reversal emulsifier, wherein the addition amount of the reversal emulsifier is 0.1-5%; (e) the balance of water. The dispersing paste is high in powder content, good in covering property, good in stability and convenient to use.

Description

technical field [0001] The invention belongs to the field of cosmetics, and in particular relates to a water-in-oil type zinc oxide dispersion slurry. Background technique [0002] Zinc oxide is an oxide of zinc. Insoluble in water, soluble in acid and strong alkali. Zinc oxide is a commonly used chemical additive, widely used in the production of plastics, silicate products, synthetic rubber, lubricants, paints, ointments, cosmetics, adhesives, food, batteries, flame retardants and other products . In the field of cosmetics, zinc oxide is an important raw material, which can be used as a covering agent, sunscreen agent, skin conditioner, etc. [0003] When zinc oxide is used, due to its original nature of large specific surface energy, the particles are easy to agglomerate, resulting in poor dispersion in solvents, easy to cause sedimentation and poor suspension, and finally appear in non-solid products. Floating color or Instability problems such as powder settling, re...
