Formic acid is characterized by its colorless liquid state and distinctive pungent odor. It is highly soluble in water and miscible with alcohol and ether. As the simplest member of the carboxylic acid family, formic acid consists of a hydrogen atom, a carbon atom, and two oxygen atoms, forming a carboxyl group (-COOH) attached to a hydrogen atom. This simplicity belies its reactivity and utility in multiple chemical reactions, including esterification, oxidation, and hydrogenation.

E322 emulsifier, or lecithin, is an essential ingredient in both the food and cosmetic industries due to its ability to stabilize mixtures and contribute nutritional benefits.
