Onitin is used primarily in the fragrance industry due to its sweet, floral, and slightly fruity aroma. It is commonly incorporated into perfumes, soaps, and cosmetic products to enhance scent profiles and provide long-lasting olfactory appeal. Its stability under various pH conditions and compatibility with other ingredients make it suitable for use in both fine fragrances and functional personal care products. Additionally, Onitin is sometimes used in household cleaning products and air fresheners for its pleasant odor and vapor characteristics.
