Irenolone is primarily used in the fragrance industry due to its pleasant, floral-woody aroma. It serves as a key ingredient in perfumes, cosmetics, and scented personal care products, offering long-lasting scent stability. Its olfactory properties make it ideal for enhancing top to middle notes in fine fragrances. Additionally, it is utilized in household products such as detergents, fabric softeners, and air fresheners for its ability to impart a clean, fresh scent. Irenolone is valued for its low volatility and resistance to degradation, ensuring consistent performance in a variety of pH and temperature conditions. It is also compatible with other fragrance components, allowing for broad formulation flexibility.
