Description
Tert-Butanol (CAS 75-65-0), also known as t-Butanol or 2M2P, is a branched-chain alcohol supplied as a clear, colourless liquid after melting. It carries no assigned E-code and is distinct from linear butanol isomers. It is available under the abbreviations T-Butanol and 2M2P across industrial and specialty chemical markets.
In personal care formulations, tert-Butanol functions as an antimicrobial agent by disrupting microbial cell membranes, extending product shelf life without relying on traditional preservative systems. In plastics processing, it acts as a heat stabilizer, reducing thermal degradation of polymer chains during high-temperature compounding. It also serves as a solvent carrier in fragrance and flavour applications, improving ingredient dispersion and delivery.
Tert-Butanol is available in technical and food-grade specifications, with food-grade material conforming to FCC standards. It falls under REACH regulation (EC 200-889-7) and is classified under HS code 29051410 for EU trade purposes. Standard packaging includes drums and IBC containers.
