Key Properties and Physical Profile

Dimethicones versatility stems from its impressive properties such as non-toxicity, thermal stability up to 150C, high purity, and inert chemical nature. Its viscosity can be adjusted from 10 cSt to 1,000,000 cSt, enabling tailored use across diverse applications. The fluid is clear, colorless, odorless, and tasteless, ensuring compatibility even in sensitive formulations such as cosmetics and pharmaceuticals.

Applications and Usage Methods

Primarily valued as a conditioning agent, lubricant, and emollient, Dimethicone enhances the performance of cosmetics, pharmaceutical formulations, industrial lubricants, and water-repellent products. Its anti-foaming and wetting abilities make it essential for various manufacturing processes. It is generally used by blending into formulations during early or intermediate processing stages.

Safety, Environmental Compatibility, and Packaging

Dimethicone is not classified as hazardous and is handled with general safety guidelines. Its environmental impact is low; it is not bioaccumulative though it does not rapidly degrade. The product comes in drums, IBCs, or customized containers, ensuring safe transportation and storage. For optimal shelf-life, it should be kept away from heat and sunlight, stored in cool, dry conditions.

FAQs of Dimethicone:

Q: How is Dimethicone produced and what is its chemical structure?

A: Dimethicone is synthesized through the polymerization of dimethyldichlorosilane, resulting in a clear, colorless polydimethylsiloxane liquid. The structural formula is [Si(CH3)2O]n, which gives it exceptional chemical stability and versatility.

Q: What are the main applications of Dimethicone in various industries?

A: Dimethicone is widely used as a conditioning agent, lubricant, and emollient in cosmetics, pharmaceuticals, lubricants, anti-foaming agents, and water-repellent products. Its inert and stable nature makes it ideal for sensitive applications.

Q: When should Dimethicone be added during manufacturing processes?

A: Dimethicone is generally incorporated during the initial or intermediate stages of product formulation to ensure homogeneous distribution, optimal stability, and effective performance of the end product.

Q: Where should Dimethicone be stored to maintain its quality and shelf life?

A: Dimethicone should be stored in a cool, dry place, away from direct sunlight and heat sources. Proper storage conditions help maintain its 2-year shelf life and preserve its quality and purity.

Q: How should Dimethicone be handled and are there any safety concerns?

A: Dimethicone is not classified as hazardous. Standard precautions, such as avoiding excessive heating and using appropriate personal protective equipment, are recommended during handling and storage.

Q: What benefits does Dimethicone provide in product formulations?

A: Dimethicone imparts smooth texture, enhances spreadability, offers lubrication, and provides water repellency. Its non-reactive and non-toxic profile also ensures safety in cosmetics and pharmaceutical products.

Q: Is Dimethicone compatible with all materials and substances?

A: Dimethicone is compatible with most materials and solvents, but should not be used with strong acids or bases, as such conditions can compromise its stability and performance.
