CarCareTruth tracks Ethyl Butyrate (CAS 105-54-4) as a car-care ingredient. It is classified as a VOC.
H226 (flammable liquid Cat 3) and H319 (eye irritation Cat 2A) per SDS classification. Flash point around 26°C — flammable at higher concentrations, but at 1–5% in a fragrance blend the mixture flash point is elevated well above the ingredient's pure-compound flash point.
Ethyl butyrate is a short-chain ester widely used as a fragrance and flavoring ingredient. It is a primary component of many fruit fragrances (pineapple, strawberry, banana). As a pure compound it is a flammable liquid (H226, flash point ~26°C) and a mild eye irritant (H319). In fragrance blends at 1–5% concentrations, the flash point of the mixture rises significantly and flammability is not a practical concern in product use. Biodegradable and not considered an aquatic toxin at product use concentrations.
