Safety score Β· 0–100

Fine

Derived from EU CosIng regulatory status, PubChem hazard data and published research. How we score.

A pyridine-ester derivative (CAS 41438-38-4). Niche cosmetic ingredient with sparse public safety data β€” proceed with caution.

Diethyllutidinate (CAS 41438-38-4) is a diethyl ester of lutidine dicarboxylic acid β€” a pyridine-ring small molecule. Its cosmetic use as a skin or hair conditioning agent is niche, and publicly available toxicology is extremely limited. Pyridine-class compounds span a wide spectrum of irritancy and sensitisation depending on substitution, and this specific compound has not been reviewed by CIR or SCCS. The previous database entry rating of 85/green was not supportable by publicly available evidence; lowered to reflect data scarcity.
