Toxicity Profile
| Route of Exposure | Oral ; Inhalation ; Dermal |
|---|---|
| Mechanism of Toxicity | Polyvinyl acetate usually contains trace amounts of its precursor, vinyl acetate. One of the metabolites of vinyl acetate, acetaldehyde, is a known animal carcinogen. Acetaldehyde can form adducts with DNA, causing damage such as cross-links. |
| Metabolism | Vinyl acetate may be absorbed following ingestion, inhalation, or dermal exposure, and distributes throughout the body. It is rapidly hydrolyzed by esterases in the blood to acetate and the unstable intermediate, vinyl alcohol. Vinyl alcohol is then rapidly converted to acetaldehyde, which in turn is metabolized to acetate in the liver. This in turn is incorporated into the "2 carbon pool" of normal body metabolism and eventually forms carbon dioxide as the major breakdown product, which is expired. |

| Lethal Dose | |
| Carcinogenicity (IARC Classification) | 3, not classifiable as to its carcinogenicity to humans. |
| Minimum Risk Level | |
| Health Effects | Vinyl acetate may affect the immune system. It may also be a carcinogen. (L1304) |

Targets
- General Function:
- Temperature-gated cation channel activity
- Specific Function:
- Receptor-activated non-selective cation channel involved in detection of pain and possibly also in cold perception and inner ear function (PubMed:25389312, PubMed:25855297). Has a central role in the pain response to endogenous inflammatory mediators and to a diverse array of volatile irritants, such as mustard oil, cinnamaldehyde, garlic and acrolein, an irritant from tears gas and vehicule exhaust fumes (PubMed:25389312, PubMed:20547126). Is also activated by menthol (in vitro)(PubMed:25389312). Acts also as a ionotropic cannabinoid receptor by being activated by delta(9)-tetrahydrocannabinol (THC), the psychoactive component of marijuana (PubMed:25389312). May be a component for the mechanosensitive transduction channel of hair cells in inner ear, thereby participating in the perception of sounds. Probably operated by a phosphatidylinositol second messenger system (By similarity).
