Recent articles have indicated by December 31, 2018, bans regarding N-Methyl-Pyrrolidone (NMP) in paint strippers from Home Depot, Lowes and Sherwin Williams.

Since these announcements, Callahan Chemical has received many customer inquiries for samples of TOU as a potential replacement for N-Methyl-Pyrrolidone.

Callahan Chemical supplies Tetraoxaundecane (TOU) manufactured by Lambiotte & Cie whose specialized acetal products are produced by reactions between alcohols and aldehydes.

TOU has nearly identical physical properties to NMP.  The solvency power (Kb) is >200 and the vapor pressure profile is the same (see below). TOU has none of the health concerns that are associated with NMP.

TOU is an excellent solvent choice for applications that involve NMP. TOU has an extremely high Kb value and is also water soluble. TOU has an excellent Health and Atmospheric Chemistry profile.

TOU is TSCA approved and NOT listed on the California Prop 65 list.
