Used in perfumery for its floral, lilac-like aroma, Methylionene adds depth and richness to fragrance compositions. It is commonly found in soaps, detergents, cosmetics, and fine fragrances due to its stable scent and ability to enhance floral accords. Its olfactory profile makes it valuable for creating violet, iris, and rose notes. Often used as a fixative, it helps prolong the scent's longevity on skin and fabrics. Methylionene is also employed in household products where a fresh, clean, floral scent is desired.
