About
A branched formate ester used in perfumery for fruity-green facets. Simple chemistry, routine fragrance use, and low exposure keep it in the green tier.
Trimethylhexyl formate (CAS 67355-38-8) is a branched aliphatic formate ester used as a fragrance ingredient. Formate esters are common fruity-green perfumery building blocks. Slow hydrolysis can release traces of formic acid, but at fragrance use levels this is not a safety concern. Industry RIFM/IFRA evaluations cover the class. No EU Annex II status.
