GUNTERSVILLE, Alabama - A liquid believed to have made two Guntersville postal workers ill Tuesday was determined to be K-Y Intense Arousal Gel that leaked from packages addressed to someone in the entertainment industry, an inspector said.

The liquid, which authorities said after initial tests Tuesday was likely non-hazardous methanol, has ingredients to "intensify sensation," including propylene glycol.

The post office was evacuated at about 9 a.m. and two workers were taken to the hospital after coming into contact with the liquid that spilled from a package.

Guntersville Police and Hazmat teams responded, retrieving a bag containing several packages with the substance on it.

The packages were addressed to someone in the entertainment industry, although that person's name was not released, said Tony Robinson, a USPS postal inspector.

Robinson said he is not sure how the non-toxic substance made the workers ill. He added that, according to USPS policy, the sender would be contacted and advised how to better pack mail in the future.

According to the Agency for Toxic Substance and Disease Registry, propylene glycol is used in cosmetics, medicines and foods and the FDA classified it as "generally recognized as safe" for use in food.
