What Is 2-p-Tolylethanol?
2-p-Tolylethanol is a synthetic fragrance ingredient with a floral, slightly woody character. It’s found in perfumes and scented products as a modifier for rose and lily accords. This molecule helps create long-lasting floral bouquets in fragrances, adding depth and persistence to floral compositions without being overpowering.
Safety Profile
USE WITH AWARENESSWhat Does 2-p-Tolylethanol Smell Like?
2-p-Tolylethanol presents a delicate floral character reminiscent of rose petals with a subtle green undertone. The initial impression is fresh and slightly powdery, evolving into a warmer, honeyed floral heart. In drydown, it reveals a soft woody-musky base that provides excellent tenacity. Compared to phenylethyl alcohol, it has more body and less sharpness, making it valuable for rounding out floral compositions.
Chemistry, Properties & Perfumer Guide
The Chemistry
2-p-Tolylethanol belongs to the aromatic alcohol class, structurally similar to phenethyl alcohol but with a methyl group para to the hydroxyl group. It’s produced synthetically through Friedel-Crafts alkylation or reduction of corresponding aldehydes. The para substitution pattern gives it distinct olfactory properties compared to its ortho and meta isomers, with better stability in formulations.
