Creosol, with the CAS number 93-51-6, is a compound that belongs to the class of phenolic compounds. It is characterized by its distinct smoky, tar-like odor, which can add depth and complexity to fragrance compositions. In perfumery, creosol is often used in small quantities to impart a woody or resinous note, making it suitable for certain types of oriental or woody fragrances. Its unique scent profile allows it to serve as a fixative, helping to stabilize and prolong the longevity of other more volatile fragrance ingredients. However, it is important to note that creosol may be subject to regulatory scrutiny due to its potential health effects. As with many aromatic compounds, safety assessments are crucial, and perfumers should be aware of any applicable restrictions or guidelines from organizations such as IFRA. While creosol is not commonly listed as a major allergen, its use should be approached with caution, particularly in formulations intended for sensitive skin or leave-on products. — AI-generated summary, 2026-09-02.
