应用领域

登记用途：Uses: CIR ingredient: Zinc Stearate、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、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 distearate is mainly used in the EU in the polymers industry as a stabilizer component (e.g. in PVC stabilisers)、lubricant、mold release agent and dusting agent for rubber (55 %). Zinc distearate is further used in the paints、lacquers and varnishing industry as a sanding and flatting agent (18%)、in the: building industry as a waterproofing agent in concrete (5%)、in the paper、pulp、board and textile industry as a waterproofing agent (2%)、in the cosmetics and pharmaceutical industry (1%)、chemical industry (1%)、metal industry (1%) and other applications.、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.、For more Uses (Complete) data for ZINC STEARATE (17 total)、please visit the HSDB record page.、Plastics -> Typical concentration range in plastic materials -> 0.5 - 1.0%、Zinc stearate is used mainly as a releasing agent and lubricant in the rubber and plastics industry. (L78)、This is an endogenously produced metabolite found in the human body. It is used in metabolic reactions、catabolic reactions or waste generation.、Use Classification: Plastics -> Polymer Type -> PVC (soft)、PVC (rigid)、PET、PA、Plastics -> Other functions -> Lubricant、Cosmetics -> Anticaking、Cosmetic colorant、Industry Uses: Filler、Not Known or Reasonably Ascertainable、Surface modifier、Intermediate、Heat stabilizer、Pigment、Lubricating agent、Other、Anti-adhesive、cohesive、Polymerization promoter、Dispersing agent、Anti-caking agent、Antioxidant、pH regulating agent、Processing aids not otherwise specified、UV stabilizer、Consumer Uses: Filler、Insulators、Household Products: Information on 63 consumer products that contain Zinc stearate in the following categories is provided:、• Hobby、Craft、• Home Maintenance、• Home Office、• Inside the Home、• Personal Care、Methods of Manufacturing: Three methods are used to produce zinc distearate: 1) the double decomposition method、2) the direct transformation process and 3) the fusion process. According to the industry only the first process generates waste water.、Action of sodium stearate on solution of zinc sulfate.、The insoluble metallic stearates are produced by reacting a selected grade of stearic acid with a caustic (usually sodium hydroxide) in an aqueous system. This produces a solution containing the soluble sodium salt of stearic acid. The insoluble metallic stearate precipitates out when a solution containing the desired metal is added to the sodium stearate solution. The insoluble stearate is then washed free of the water-soluble impurities、dried、milled、and packaged.、Insoluble metallic stearates、An aqueous solution of zinc sulfate is added to sodium stearate solution to precipitate zinc stearate. The zinc stearate is then washed with water and dried. Zinc stearate may also be prepared from stearic acid and zinc chloride.、Formulations、Preparations: Zinc stearate USP、60 g and 125 g shaker containers.、Grades: USP、technical、available from chick edema factor.、HyTech、HyDense、HyQual、RSN 131-HS、Wettable powder、DZS-36、SI-50、IPS、granular、XM powder、XM ultrafine dispersion SP grades、USP、Usually occurs as mixture of zinc salts of stearic and palmitic acids、and usually with some excess of zinc oxide. Contains 13.5-15% zinc oxide.、Consumption Patterns: Table: Distribution and EU tonnage for the different use categories of zinc distearate in the EU for 1997 [Table#826]、U.S. Production: 2023: 25、000、000 - <40、000 lb、2022: 40、000 - <55、2021: 40、2020: 25、(1972) 8.8X10+9 GRAMS、(1975) 6.9X10+9 GRAMS、(1985) 27、925X10+3 lb、Octadecanoic acid、zinc salt is listed as a High Production Volume (HPV) chemical (65FR81686). Chemicals listed as HPV were produced in or imported into the U.S. in >1 million pounds in 1990 and、or 1994. The HPV list is based on the 1990 Inventory Update Rule. (IUR) (40 CFR part 710 subpart B、51FR21438).、For more U.S. Production (Complete) data for ZINC STEARATE (6 total)、General Manufacturing Information: Other (requires additional information)、Printing Ink Manufacturing、All Other Basic Organic Chemical Manufacturing、Food、beverage、and tobacco product manufacturing、Miscellaneous Manufacturing、All Other Chemical Product and Preparation Manufacturing、Adhesive Manufacturing、Fabricated Metal Product Manufacturing、Plastics Material and Resin Manufacturing、Synthetic Rubber Manufacturing、Plastics Product Manufacturing、Electrical Equipment、Appliance、and Component Manufacturing、Soap、Cleaning Compound、and Toilet P。
