    Trans-8-Hydroxylinalool (CAS 75991-61-6) is a hydroxylated terpene alcohol derived from linalool, offering a fresh, floral, slightly fruity-citrus tonality with soft woody-clean facets; its moderate-to-low volatility and higher polarity aid dispersion in aqueous systems with appropriate solubilizers, making it valuable in fine fragrance to round mid notes, soften sharp terpenic edges, enhance naturalness, and extend substantivity, and in personal care (shampoos, body washes, soaps, deodorants) and home care (detergents, softeners, air care) for malodor coverage and clean impressions; it is explored as a trace-level flavor modulator where permitted by local regulations; serves as a versatile intermediate for pro-fragrances (esters, carbonates) enabling moisture/pH/enzyme-triggered release and for microencapsulation to boost fabric longevity; used as an analytical standard/marker in essential oils, wine and fermented beverages, and in plant/microbial linalool metabolism studies; in vitro data suggest antimicrobial/deodorizing potential supporting cleaning and air-care uses, subject to product-specific safety/efficacy assessments, IFRA/REACH compliance, and allergen management related to linalool/oxidation products.
