Personality
Despite being portrayed as "harsh" and "evil" by others, Formaldehyde is one of the most careful Chemicals. She was grown with a great urge to be a poison and ended up working together with humans. She wanted to follow her mother's steps because she mistook Methanol for a "villain", later in her life, Formaldehyde realised that evil and good were just human values. She has accepted her toxicity as her own "nature" which cannot be changed. Formaldehyde is still often portrayed as evil by humans.

Formaldehyde wants everything clean and sterilised. Just like Isopropyl Alcohol, she cannot stand filth. She would rather hang out with Solvents than humans.

Physical appearance
Formaldehyde has straight blond hair that was previously dyed blue as her brother DME did. She cuts her hair frequently because she does not want her hair to get dirty during work.

Formaldehyde almost always wears a bleached lab coat, even over her uniform.

Relationships
Formaldehyde has two sons named Formic Acid and Methanediol, and two daughters; Bischloromethyl Ether, Acrolein. She has dated Urea, Acetone, Hydrochloric Acid, Acetaldehyde, Ammonia and also married to Phenol in 1909.
