Octyl methoxy cinnamate

Among all these UV-B Sunscreen agents octyl methoxy cinnamate accounts for almost 90% of all the Sunscreen agents and has been occupying a pride of place. Besides, octyl methoxy cinnamate (OMC) also known as 2-ethyl-hexyl cinnamate is produced from p-cresol via p-anisic aldehyde and will be discussed here in some detail.

Soon p-anisic aldehyde produced from p-cresol through the process of methylation of the hydroxy group and subsequent oxidation of the methyl group, turned out to be a very important organic chemical and an attractive outlet of p-cresol. p-Anisic aldehyde is effectively used for making octyl methoxy cinnamate (an UV-B sunscreen chemical) and dilitiazem (an antihypertension drug). Subsequently, a series of downstream derivatives of p-cresol have been synthesized and commercially produced.

UVB absorbers are chemicals that absorb in the 290-320 nm and include PABA and its derivatives, the salicylates, cinnamates, and camphor derivatives (i.e., octyldimethyl PABA, octyl salicylate, 2-ethoxyethyl-p-methoxy cinnamate).
