数据库记载的用途

  • Used to manufacture drugs, lacquers, and plastics; also used as a dietary supplement, waterproofing agent, heat and light stabilizer, and lubricant; [HSDB] Stearates are salts of octadecanoic acid. Zinc stearate is used in cosmetic powders for its adhesive properties. [ACGIH]
  • Used in cosmetics, pharmaceuticals, food additives, waterproofing agents, plastic stabilizers, emulsifiers, and rubber lubricants and dusting agents; Stearic acid occurs naturally in human and animal fats and oils and in some vegetable oils, including cocoa oil. Stearic acid can be prepared from animal fat (triglyceride) by treating with water at high temperature, leading to hydrolysis of triglycerides, or by hydrogenation of unsaturated vegetable oils such as cottonseed oil. [ACGIH]
  • In tablet manufacture; in cosmetic and pharmaceutical powders and ointments.
  • Zinc stearate has been used in baby toiletries and bath powders as a dry lubricant to absorb moisture and prevent chafing.
  • Zinc stearate serves as an opacifying agent in cleansing creams and shampoos. In hair grooming products, it is used as a water-in-oil emulsifier.
