Description

Dimethylethylcarbinol (CAS 75-85-4 ), also known commercially as amylene hydrate and abbreviated as TAA (tert-amyl alcohol), is a tertiary alcohol used across polymer processing, flavoring, and cosmetic formulations. It functions primarily as a stabilizer, curing co-agent, and flavoring ingredient depending on the application sector. In plastics and polymer manufacturing, TAA acts as a stabilizer and cross-linking agent. In peroxide-cured systems, it improves process consistency and end-product integrity. Food and beverage producers use it as a flavoring ingredient, where it contributes characteristic notes to finished products at regulated usage levels. In personal care formulations, it functions as a solvent and co-solvent that aids ingredient compatibility and helps control viscosity in topical products. It also serves as an intermediate in the synthesis of tert-amyl methyl ether. This material is also used for other fuel additives, representing a distinct industrial demand channel. Dimethylethylcarbinol is supplied as a clear liquid in drum and IBC quantities for various industrial needs. Bulk tanker options are available for larger procurement volumes. Technical grade is the most common commercial specification, though material meeting food-grade and flavor-industry purity standards is also available. Buyers should confirm grade suitability against relevant specifications such as FCC for food and flavoring end uses. This ensures compliance with safety and quality requirements for regulated applications. Contact us for supply of Dimethylethylcarbinol Request Quote
