The new LOW VOC paints are causing new IAQ issues with more complaints than ever before. What will the paint companies do next?

There is a perception that low VOC paints and coatings emit fewer VOCs than traditional latex-based and oil-based paints used in the past. This isn’t necessarily the case. What has changed is the type of VOCs emitted from low VOC paints and the volatility of these solvents. 

 
Common VOCs observed in homes and businesses related to the low VOC paints and coatings are Texanol A and B, 2-butoxyethanol, and glycol ethers based on diethylene glycol and dipropylene glycol.
 Texanol A (Propanoic acid,2-methyl-, 1-(2-hydroxy-1-methylethyl)-2,2-dimethylpropyl ester (CAS-number 74367-33-2) and Texanol B (Propanoic acid,2-methyl-, 3-hydroxy-2,4,4-trimethylpentyl ester (CAS-number 74367-34-3) are ester alcohols and are used as coalescing agents for low VOC latex paints. 

The use of the terms "Texanol" and "Texanol A" and "Texanol B" can be misleading and should therefore be replaced by the two compounds' formal name and Cas-number. Texanol A should be replaced by Propanoic acid,2-methyl-, 1-(2-hydroxy-1-methylethyl)-2,2-dimethylpropyl ester (Cas-number 74367-33-2) and Texanol B should be replaced by Propanoic acid,2-methyl-, 3-hydroxy-2,4,4-trimethylpentyl ester (Cas-number 74367-34-3).
