a Includes mono- and di-ethers of ethylene glycol, diethylene glycols and triethylene glycol; R-(OCH2CH2)RR-OR where:

n = 1,2, or 3,

R = alkyl or aryl groups R' = R, H, or groups which, when removed, yield glycol ethers with the structure: R-(OCH2CH2)n - OH. Polymers are excluded from the glycol category.

b Includes organic compounds with more than one benzene ring, and which have a

boiling point greater than or equal to 100°C.
