Isopropyl Alcohol
Isopropyl alcohol is permitted as a residual solvent in food extraction with strict limits (typically <50 ppm). Direct ingestion is toxic, causing CNS depression and metabolic acidosis.
What it is
Isopropanol (2-propanol), a colorless solvent used industrially and as a topical disinfectant; toxic if ingested in significant amounts.
Limited use as a solvent/extraction aid in food processing; not for direct consumption. Maximum residual limits set by FDA.
Why it's flagged
- toxic if ingested in significant amounts
- limited to residual solvent levels in food
- CNS depressant
What regulators actually say
"Isopropyl alcohol may be safely used as a solvent in spice oleoresins, lemon oil, and hops extract; residue limits are specified in 21 CFR 173.240."
"Directive 2009/32/EC sets maximum residue limits for extraction solvents used in the production of foodstuffs and food ingredients."
