Description
Diacetone alcohol (CAS 123-42-2, EC 204-626-7, formula C6H12O2) is a ketone-alcohol solvent also known by the trade names Tyranton and Pyranton A, and referred to in industry as diketone alcohol or diacetonyl alcohol. It carries no assigned E-code and is classified under HS code 29144000.
In coatings and adhesives, diacetone alcohol acts as a slow-evaporating solvent that improves flow and leveling while reducing blushing in high-solids formulations. In polymer systems, it functions as a crosslinker by reacting with adipic acid dihydrazide to form hydrazone bonds, enabling room-temperature cure in waterborne dispersions. It also serves as a flavorant and fragrance carrier in food and personal care applications.
Diacetone alcohol is available in industrial and high-purity grades, with select batches meeting FCC specifications for food-contact use. It is fully registered under REACH and supplied in standard drum and IBC formats. Buyers should confirm grade suitability against applicable regional food or cosmetic regulations before use.
