Palmitic acid ethyl ester(628-97-7), also known as ethyl palmitate, it the ethyl ester form of palmitic acid. It can be used as a hair- and skin-conditioning agent. It has been shown that the combination between palmitic acid ethyl ester and cobra venom factor can enhance the survival of heterologous erythrocyte. Recent study has also demonstrated the potential anti-inflammatory activity of palmitic acid ethyl ester in several animal models.

Ethyl palmitate(628-97-7) is a one of the major volatile compounds found in cooked rice and Luzhou-flavor raw liquor. It occurs naturally in licorice root and chamomile.
| [Safety]
Palmitic acid ethyl ester(628-97-7), also known as Ethyl palmitate, is a versatile aromatic ester compound widely used as a food additive, fragrance ingredient and cosmetic emollient. Due to the lack of conclusive animal or human evidence, the substance is not classified as "harmful by ingestion". After ingestion, the substance may still harm personal health, especially if there is already significant damage to organs (such as liver, kidneys). Gastrointestinal discomfort may cause nausea and vomiting. However, in an occupational environment, unintentional ingestion is not considered a cause for concern. The Cosmetic Ingredient Safety Panel has evaluated the safety of palmitic acid esters. The panel evaluated the scientific data and concluded that ethylhexyl palmitate, cetyl palmitate and isopropyl palmitate are safe as cosmetic ingredients.
| [Synthesis]
Synthesized by immobilized lipase-catalyzed alcoholysis and esterification in organic solvents. |
