Definition
2,2,4-Trimethyl-1,3-pentanediol (TMPD) glycol, with one primary and one secondary hydroxyl function, shows the typical reactivity of a diol. In comparison to other diols, such as 1,4-cyclohexanedimethanol) or NPG (Neopentyl glycol), TMPD glycol has an unsymmetrical structure and shielded hydroxyl groups.
Flammability and Explosibility
Non flammable
Toxikologie
2,2,4-trimethyl-1,3-pentanediol (TMPD Glycol) is classified as "slightly toxic". In rabbits, moderate eye irritation was observed. Slight to no skin irritation occurred in guinea pigs, and no skin sensitization was found. Repeated skin application studies in humans gave no evidence of irritation, sensitization, photosensitization, or systemic toxic effects. In humans, TMPD glycol is rapidly excreted in the urine, partly unchanged, partly as the glucuronide and sulfate conjugates, and partly as 2,2,4-trimethyl-3-hydroxyvaleric acid. LD50 2000 (rat, oral), LD50 145 (rat, intravenous).
