Product Description
Our Terpinen-4-ol is a high-purity natural monoterpene alcohol refined from premium natural tea tree oil. Terpinen-4-ol (CAS 562-74-3), also known as 4-Terpineol or 4-Pinenol, is the dominant bioactive component that determines the efficacy and fragrance quality of tea tree oil. Different from industrial phenolic monomers such as cresol series and guaiacol focused on resin synthesis and industrial modification, and differentiated from quinone-structured Thymoquinone focused on high-strength pharmacological activity,Terpinen-4-ol is a multi-functional natural active ingredient integrating cosmetic antisepsis, skin soothing and daily fragrance modulation. It balances mildness and high efficiency, becoming a core raw material for clean cosmetic formulas, natural antibacterial products and high-end essence blending. As a professional Terpinen-4-ol supplier, we provide high-purity, low-odor, high-activity natural Terpinen-4-ol raw materials for global cosmetic manufacturers, daily chemical enterprises and biomedical research institutions.
Terpinen-4-ol has irreplaceable application advantages in the natural active ingredient industry. As the core active substance of tea tree oil, it bears almost all the antibacterial and anti-inflammatory effects of tea tree essential oil. Compared with crude tea tree oil with complex impurity components and unstable efficacy, single-component high-purity Terpinen-4-ol has stable activity, controllable odor and accurate dosage, effectively solving the problems of formula instability, inconsistent fragrance and weak efficacy of traditional tea tree oil additives. Its unique monoterpene alcohol structure endows it with broad-spectrum bacteriostatic ability against bacteria and fungi, as well as mild anti-inflammatory and skin barrier repair effects. In addition, it has excellent natural spice modulation performance, widely used in lavender, geranium and citrus essence formulas, with fresh and layered woody-earth aroma.
Manufactured by Shaanxi BAISFU Bio-Engineering Co., Ltd., our premium Terpinen-4-ol adopts natural tea tree oil fractional distillation combined with multi-stage high-vacuum precision purification technology. We remove redundant terpene impurities, residual wax and peculiar odor components in crude essential oil, fully retain the pure Terpinen-4-ol active structure, and avoid active ingredient inactivation caused by high-temperature processing. The whole production process complies with cosmetic-grade and food-grade safety standards, ensuring zero harmful residue, mild texture and pure fragrance of the finished product. Compared with ordinary industrial-grade Terpinen-4-ol, our product features higher single-component purity, lower irritancy and better formula compatibility, perfectly adapting to high-end clean beauty and natural antibacterial product development needs.
Every batch of Terpinen-4-ol undergoes strict multi-dimensional quality inspection, including GC high-precision purity analysis, NMR structural verification, mass spectrometry molecular identification and microbial limit detection. It ensures ultra-high single-component purity, no mixed active impurity interference, stable physical and chemical properties, and consistent batch efficacy. The product presents transparent oily liquid state with pure and mild natural spice aroma, good solubility in oil-phase and organic solvents, and excellent compounding stability. All indicators meet international daily chemical, cosmetic and fine chemical standards, supporting safe and efficient large-scale industrial applications and formula research and development.
We maintain sufficient inventory and complete qualification documents for bulk Terpinen-4-ol supply. Whether you need natural antibacterial and soothing raw materials for acne skincare formulas, mild preservative additives for clean cosmetics, or high-quality spice monomers for daily essence blending, our high-purity Terpinen-4-ol is a cost-effective and high-value natural active raw material choice for global buyers.
