- OSHA does not have a PEL for n-valeraldehyde.
- Vapor/air mixtures of valeraldehyde may be explosive.
- Valeraldehyde is listed by the FDA as a synthetic flavoring substance that is permitted for direct addition to food for human consumption (21 CFR 172.515), and it occurs naturally in a wide variety of foods (e.g., alcoholic beverages, dairy products, cocoa, popcorn, potato chips).
- Valeraldehyde was one of several aldehydes that evoked erythema of the skin in volunteers when applied to the skin as a patch containing 25 µl of a 75% solution in water for five minutes.
