1-(p-Alkyl)phenylethanols were prepared by two-step synthesis: acylation of alkylbenzenes (alkyl = methyl, propyl, isobutyl, tert-butyl) and subsequent hydrogenation of the resulting p-alkylacetophenones. The resulting 1-(p-alkyl) phenylethanols as well as their esters have peculiar flavoring properties that suggest their use as fragrances.
Among the substances mentioned above, only p-methylacetophenone, p-isobutylacetophenone, p-tert-butylacetophenone and 1-(p-methyl)phenylethanol were considered as fragrances by Arctander.
Special attention was paid to p-acetophenone derivatives, which can enrich the family of currently known flavors. Their preparation generally follows the reactions shown in Scheme 1.
!['[L]arger/international customers require compliance to foreign standards such as Leaping Bunny, EU standards compliance, etc.,' says Cohere Beauty's John Nolfi. '[T]he trend is more about being able to support 'clean' formulations with some data.'](https://img.perfumerflavorist.com/mindful/allured/workspaces/default/uploads/2026/08/cg-productionassembly.StVSo2THhj.jpg?auto=format%2Ccompress&fit=crop&h=191&q=70&w=340)
