Product Description

NAME: Stearic Acid

CAS NUMBER: 57-11-4

HS CODE: 29157000

Application:
1. It can be used as a vulcanizing active agent for natural rubber, synthetic rubber and latex.
2. Used in medicine to prepare ointment, suppository, etc.
3. In the electronic ceramic hot die casting molding process, it can improve the slurry viscosity and prevent the bad body wax cracking.
4. It can be used as a plasticizer and stabilizer in plastics
5. It can be used as release agent for electronic components in electronic products.
6. It can also be used in the manufacture of cosmetics, candles, waterproofing agents, polish agents, etc

In medicine, its application mainly is:

1. Tablet and capsule manufacturing: Stearic acid is commonly used as a lubricant and flow agent in tablet and capsule production. It helps in the smooth release of the tablet or capsule from the mold and prevents sticking during manufacturing processes.
2. Topical preparations: Stearic acid can be found in various topical formulations such as creams, ointments, and lotions. It acts as an emulsifier, helping to stabilize the formulation and improve its texture and consistency.
3. Controlled-release drug delivery systems: Stearic acid is used in the development of controlled-release drug delivery systems. It can be incorporated into matrices or coatings to control the release rate of active pharmaceutical ingredients (APIs) over an extended period.
4. Suppository bases: Stearic acid is sometimes used as a suppository base due to its solidifying properties. It helps in the formation and stability of suppositories, which are solid dosage forms inserted into the rectum or vagina for localized or systemic drug delivery.
5. Parenteral formulations: Stearic acid derivatives, such as stearoyl macrogolglycerides, are used as solubilizing agents in parenteral formulations. They enhance the solubility and stability of poorly soluble drugs for intravenous administration.

Description:
Stearic acid is one of the main long-chain fatty acids that make up oils and fats. It exists in animal fats, oils and some vegetable oils in the form of glycerides. Stearic acid is obtained by hydrolysis of these oils. Stearic acid is a kind of fatty acid widely existing in nature. It has the chemical properties of general carboxylic acid. Almost all oils contain stearic acid with different content. The content of stearic acid in animal fat is higher, such as 24% in butter, less in vegetable oil, 0.8% in tea oil and 6% in palm oil, but the content in cocoa butter is higher. Up to 34%.
