Description

Siloxanes,Dimethyl,Isopropylmethyl,Methyl1-Methyl-C9-49-Alkyl is a specialized organosilicon compound, a member of the alkylmethylsiloxane family. This chemical is valued for its unique combination of silicone properties and the reactivity of its alkyl chain, making it a versatile intermediate and functional additive. It is primarily sought by manufacturers in the personal care, coatings, and specialty chemical industries for formulating products requiring tailored surface activity, release properties, or hydrophobic modification.

Application

• Personal Care & Cosmetics: Acts as an emollient, conditioning agent, and texturizer in hair care products, skin creams, and antiperspirants.
• Release Agents & Molding: Used as a key component in mold release formulations for plastics, rubber, and composite materials.
• Coatings & Inks: Functions as a flow and leveling additive, slip agent, and mar-resistant additive to enhance surface properties.
• Specialty Lubricants & Greases: Serves as a base fluid or additive to improve thermal stability, water repellency, and lubricity.
• Adhesives & Sealants: Imparts hydrophobicity and improves compatibility in silicone-modified adhesive systems.
• Chemical Intermediate: Utilized in further synthesis to create custom silicone polymers, surfactants, or functional fluids.
• Textile & Fiber Treatment: Applied as a softener and water-repellent finish for fabrics and nonwovens.

Quality Control

Our Siloxanes,Dimethyl,Isopropylmethyl,Methyl1-Methyl-C9-49-Alkyl is produced under a strict quality management system. Each batch undergoes rigorous analytical testing to ensure consistency in composition, viscosity, and functional performance. Certificates of Analysis (COA) documenting key parameters are available upon request to support your quality assurance and regulatory compliance needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area away from incompatible materials such as strong bases and organic solvents. Recommended storage temperature is between 15°C and 25°C (59°F and 77°F). Keep container tightly sealed when not in use to prevent contamination and moisture absorption.
