High-Purity Grade | The Classic Herbaceous-Woody Fragrance Ingredient

Product Name: Alpha-Terpinyl Acetate

CAS No.: 80-26-2

Chemical Formula: $C_{12}H_{20}O_2$

Category: Terpene Esters / Aroma Chemicals / Pine Chemical Derivatives

1. Product Overview

Alpha-Terpinyl Acetate is a vital ester synthesized through the esterification of $\alpha$-Terpineol with acetic anhydride. Found naturally in Cardamom and Pine oils, it is widely recognized for its versatile Herbaceous and Woody character.

Renowned for its exceptional chemical stability—particularly its resistance to hydrolysis in alkaline media and heat stability—it serves as a cost-effective alternative to natural essential oils like Lavender and Bergamot. It is an indispensable fixative and modifier in both functional and fine fragrance formulations.

2. Odor Profile

• Olfactory Group: Woody / Floral / Citrus

• Description: A fresh, herbaceous fragrance with sweet underlying notes. It exhibits a characteristic Lavender and Bergamot profile, supported by a mild woody base and subtle spicy-citrus nuances.

• Performance: Excellent tenacity from heart to base notes, effectively enhancing the “lift” and diffusivity of the overall fragrance formula.

4. Key Applications & Use Cases

Thanks to its stable ester structure, Alpha-Terpinyl Acetate remains stable even in harsh pH environments, making it ideal for the following sectors:

A. Functional Fragrances (Soaps & Detergents)

• The Science: Its high resistance to hydrolysis makes it the preferred choice for alkaline products where other esters might break down.

• Application Examples:

  • Bar Soaps: Used at $5\% – 15\%$ levels in Lavender or Cologne-type soaps to provide a clean scent profile without discoloration.

  • Fabric Care: Acts as a freshening agent in liquid detergents, ensuring scent retention on fabrics.

B. Fine Fragrances (Perfumery)

• The Science: Acts as an extender and modifier for expensive natural oils, essential for building Fougère and Citrus accords.

• Application Examples:

  • Men’s Colognes: Enhances the top notes of Bergamot and Lavender, adding a cooling, herbaceous touch.

  • Essential Oil Reconstruction: Used widely (up to $20\% – 30\%$) in reconstituting artificial Lavender, Geranium, and Petitgrain oils.

C. Air Care & Industrial Masking

• The Science: Its sharp, pine-citrus character effectively neutralizes malodors.

• Application Examples: Automotive air fresheners, industrial floor cleaners, and solvent masking agents.

D. Flavoring Agents

• The Science: Used in minute traces to provide spicy and citrus background notes.

• Application Examples: Berry flavors (e.g., Raspberry), Ginger, and Spice blends (Compliant with FEMA GRAS standards where applicable).

5. Packaging & Storage

• Packaging: 185kg Galvanized Iron Drum / ISO Tank.

• Storage: Store in a cool, dry, and well-ventilated area. Keep away from heat sources and strong oxidizers.

• Shelf Life: Stable for 24 months under recommended storage conditions.
