Retinyl Linoleate is the linoleate ester of retinol. In leave-on oils and creams it is an oil-phase retinyl ester, not free retinol and not retinoic acid. This grade is a yellow to orange viscous oil.

Night creams and treatment oils continue to specify this INCI when a linoleate retinyl ester is required. Cosmetic-grade Retinyl Linoleate remains a bulk ester when the assay is on the COA.
