This alcohol, an isomer of the widely used Phenylethylalcohol, finds only limited use as such in perfumes. Its esters are often better known, the acetate in particular a commonly used perfume material. The alcohol itself may lend the appropriate dry notes to a Lilac, or the earthy-woody and delicate green notes to a Mimosa, but it fails to provide a generally acceptable and versatile foundation for any type of perfume. A truly pure, olfactorily pure, Methylphenylcarbinol provides very pleasant and soft notes for Narcissus, Violet, Honeysuckle and a multitude of florals and semi-florals, as well as Oriental and Chypre-type fragrances.
The alcohol is also used in flavor compositions, such as imitation Strawberry, Honey, and in various fruit complexes or in Oriental Rose flavors. The concentration used is normally about 1 to 10 ppm in the finished product.
