alpha-Terpineol
Alpha-Terpineol 95% is a high-purity terpene alcohol, typically presenting as a colourless transparent liquid with a distinctive lilac and pine aroma. As a versatile chemical, it can be sourced both naturally (e.g., via distillation from tree extracts like pine oil) and synthetically. Industrially, alpha-Terpineol is primarily produced by hydrating alpha-pinene or dehydrating terpin hydrate, with the synthetic process often resulting in isomers such as β-Terpineol and γ-Terpineol.
It is widely used as a key component in fragrances such as lilac and lime. alpha-Terpineol also serves as a raw material for synthesizing other aromatic chemicals.

Storage
- Environmental & Temperature Control:
- Store in a cool, dry, well-ventilated area, and protect from light.
- Avoid high temperatures to maintain product stability and prevent decomposition or degradation.
- Container Management & Prevention:
- Ensure containers are tightly closed to prevent volatilisation and external contamination, and are clearly labelled.
- Ground all equipment containing the material to prevent static build-up (given its flammable liquid nature).
- Hazard Isolation:
- Keep storage areas away from heat, sparks, open flames, and all sources of ignition.
- Store (as a flammable liquid) in a separate safety storage cabinet or room.
- Keep away from incompatible materials, especially strong oxidisers and strong acids, to prevent hazardous reactions.
- Safe Handling & Inspection:
- Handle carefully, and stack stably.
- After prolonged storage, always check quality before use, for example, its appearance, odour, refractive index, or relative density.
- Compliance & Emergency Preparedness:
- Strictly comply with all national and local safety regulations, particularly those pertaining to flammable liquid storage.
- Ensure emergency plans are in place for unforeseen circumstances (e.g., spills or fire).
