For chemical formulators and procurement specialists in the flavor and fragrance industry, a deep understanding of an ingredient's chemical properties is fundamental to successful product development. 4-tert-Butylcyclohexyl Acetate (PTBCHA), identified by CAS 32210-23-4, is a synthetic ester widely utilized for its distinctive woody-floral scent and remarkable performance characteristics. This article explores the key chemical attributes of PTBCHA that make it such a valuable component in various fragrance applications.

Key Chemical Characteristics of PTBCHA

PTBCHA is an ester formed from tert-butylcyclohexanol and acetic acid. Its molecular formula is C₁₂H₂₂O₂, with a molecular weight of approximately 198.3 g/mol. The structure features a cyclohexyl ring substituted with a tert-butyl group and an acetate ester group. This specific molecular architecture contributes significantly to its olfactory profile and physical properties.

  • Appearance: PTBCHA is typically a colorless to pale yellow, clear liquid.
  • Odor: It possesses a characteristic woody, floral, and often slightly herbaceous scent, described by perfumers as clean and powdery.
  • Purity: High-quality PTBCHA is usually available with an assay of 98% or higher, ensuring consistent olfactory impact.
  • Solubility: It exhibits good solubility in common organic solvents like ethanol and fragrance oils, but only slight solubility in water.
  • Boiling Point: PTBCHA has a relatively high boiling point (around 228-230 °C at atmospheric pressure), contributing to its substantivity and longevity in fragrance applications.
  • Flash Point: With a flash point typically above 90°C, it is considered a stable liquid under normal handling and storage conditions.

Stability and Application Suitability

The stability of PTBCHA is a major advantage for formulators. It demonstrates excellent resistance to degradation, particularly in:

  • Alkaline Environments: This makes it highly suitable for use in soaps, detergents, and other cleaning products where the pH is often alkaline.
  • High-Surfactant Systems: It remains stable and effective even in formulations with high concentrations of surfactants, common in personal care and household cleaning products.
  • Thermal Stability: PTBCHA can withstand moderate processing temperatures without significant decomposition.

This inherent stability ensures that fragrances containing PTBCHA maintain their intended scent profile over the product's shelf life and during use. When you buy 4-tert-Butylcyclohexyl Acetate, understanding these properties allows for more confident formulation and product development.

Sourcing and Procurement Considerations

For businesses looking to secure a reliable supply of this essential aroma chemical, sourcing from a reputable 4-tert-Butylcyclohexyl Acetate supplier in China or other global markets is advisable. When comparing prices, consider the overall value, including purity, consistency, and the supplier's ability to provide technical support and regulatory documentation. Whether you are seeking a specific grade or bulk quantities, a well-chosen supplier will be instrumental in optimizing your procurement strategy for 4-tert-Butylcyclohexyl Acetate.
