About
2-ETHYLPENTYL-1,3-DIOXOLANE is a cosmetic ingredient used in product formulation. Exercise caution due to limited available safety data.
2-Ethylpentyl-1,3-dioxolane is a cyclic acetal fragrance ingredient providing fresh, green, and slightly fruity notes reminiscent of melon and cucumber. It is not listed under EU restriction annexes, though the acetal functional group means it can hydrolyse slowly in aqueous formulations, limiting its use to products with appropriate pH and water activity. IFRA guidelines restrict its maximum use level.
