Expert Verdict

Relatively limited standalone safety data compared to parent compounds. For COSMOS/ECOCERT compliance, confirm natural origin certification if claiming natural. Ester hydrolysis in extreme pH conditions could release free glycol and citric acid — not a concern at normal cosmetic pH (4.5–6.5)
