How it works

Cetyl palmitate is one of several cetylated esters used in joint health complexes. As with related compounds, the proposed mechanism is anti-inflammatory or joint-lubricating. Isolated cetyl palmitate has minimal independent research; effects are inferred from CFA complex studies. In cosmetics, cetyl palmitate is widely used as a skin emollient and emulsion stabilizer due to its waxy texture and moisture-locking properties.
