Potassium 2-ethylhexanoate

Potassium 2-ethylhexanoate (CAS 3164-85-0) is the potassium salt of 2-ethylhexanoic acid, commercially available under trade names including Dabco K-15, Dabco T 45, and Hexcem 977. It carries no assigned E-code and is classified under HS code 2915.90.5050.

In polyurethane manufacturing, it functions as a trimerisation catalyst, promoting the formation of isocyanurate (PIR) linkages that improve thermal stability in rigid foam systems. It also serves as a pH buffer and preservative in personal care formulations, and as a flavouring agent or acidulant in food applications where controlled potassium delivery is required.

The material is supplied as a solid and is subject to REACH registration requirements within the EU. Procurement teams should confirm grade suitability against FCC specifications for food-contact applications or relevant cosmetic safety assessments under EU Regulation 1223/2009. Packaging formats and minimum order quantities vary by supplier.
