- IUPAC: 4-Hydroxy-3-methoxybenzaldehyde
Very low health concern. Vanillin is one of the most studied fragrance compounds and is GRAS (Generally Recognized As Safe) for food use. At the trace concentrations used in car care products it poses negligible risk. Potential sensitizer in rare individuals with extreme fragrance sensitivity.
Vanillin is the primary aromatic compound in vanilla beans and is produced both naturally (from vanilla pods) and synthetically (from guaiacol). It is used as a fragrance additive in car care products at very low concentrations.
Vanillin has an excellent safety and environmental profile: readily biodegradable, low aquatic toxicity, no persistence or bioaccumulation, and decades of safe use in food and cosmetics. It is one of the least concerning fragrance ingredients that appears in car care formulations.
