Description
Undecanedioic acid (CAS 1852-04-6, EC 217-440-6), also known as hendecanedioic acid, NSC 400241, and RARECHEM AL BO 0436, is a saturated C11 dicarboxylic acid with no assigned E-code. It belongs to the organic acids category and is classified under HS code 29171900 for customs and trade purposes.
In personal care formulations, it functions as an emulsifier and emulsion stabilizer by bridging oil and water phases through its bifunctional acid groups, improving texture consistency in creams and lotions. In lubricant and metalworking applications, its polar carboxyl groups adsorb onto metal surfaces, reducing friction and providing boundary lubrication under load.
Undecanedioic acid is supplied as a white to light yellow powder compliant with REACH regulations. Procurement teams should confirm grade specifications against FCC or cosmetic-grade standards depending on the target application. Standard packaging formats for B2B supply typically include 25 kg bags or fiber drums.
