Retinyl propionate (CAS 7069-42-3) is the propionic-acid ester of all-trans retinol, molecular formula C23H34O2 and molecular weight 342.51. It is produced synthetically by esterifying retinol with propionic acid and assayed by HPLC, with potency standardised in International Units. Among the family's preformed retinyl esters its three-carbon propionyl chain sits between the two-carbon acetate (328.49) and the sixteen-carbon palmitate (524.86), so its retinol load per gram lies between those two esters, while the ester bond makes it more oxidation-stable than free retinol. It is used mainly in topical and cosmetic formulations, with minor oral use, and is supplied chiefly as an oil dilution. We manufacture it into softgels, capsules and liquids.
