No GHS classification for acetyl tributyl citrate; not Prop 65-listed, not an asthmagen, not a sensitizer. Citrate esters are generally recognized as low-toxicity plasticizers/solvents, including in food-contact and cosmetic applications at regulated concentrations.

Acetyl tributyl citrate (ATBC) is a citrate ester commonly used as a plasticizer and low-volatility solvent, valued as a lower-toxicity alternative to phthalate plasticizers. In SONAX's CC36 GlossCoat aerosol, it functions as part of the solvent/carrier system alongside naphtha and hydrotreated alkanes.

No hazard classification is triggered by acetyl tributyl citrate in the finished-product SDS; it is not Prop 65-listed, not an asthmagen, and not aquatic-toxic. Citrate esters as a class are readily biodegradable and are used in food-contact and cosmetic formulations at regulated concentrations, reflecting their comparatively benign toxicological profile.
