Regarding uses and applications, -Terpinene is widely used in the fragrance and flavor industry for perfumes, soaps, detergents, and air fresheners to impart fresh citrus-herbal notes. It is also used in cleaning products and personal care formulations. Additionally, it serves as an intermediate in chemical synthesis and essential oil blends.
