  • Applications

    p-Mentha-1,5-dien-8-ol (CAS 1686-20-0) is a terpenic, herbal–pine monoterpene alcohol used as a fragrance and flavor ingredient in fine fragrances, household cleaners, personal care products, and air fresheners; in foods and beverages it is dosed at very low levels to tweak top notes and boost freshness; in cosmetic and personal care formulations it serves as an odor modifier/deodorant component and sometimes as a skin-penetration co-enhancer or fragrance carrier; in aroma R&D and manufacturing it is employed as a GC/MS reference and as a synthetic intermediate to prepare esters (e.g., acetates) and oxidized derivatives with distinctive odors; additionally, like related monoterpenols, it is explored for antimicrobial, antifungal, deodorizing, and insect-repellent functions for use in nature-derived preservatives, bio-deodorizers, and material-protection blends, with practical use guided by safety assessment, IFRA guidance, and product-specific maximum-use limits.
