benzoin resin replacer

Benzoin resin replacer is a synthetic fragrance material characterized by its balsamic, vanilla, powdery, and woody aroma notes. Also known by the synonym benzoin oliffac 63, it serves as a substitute for benzoin absolute in various perfumery applications. This compound is classified as a fragrance agent and possesses a specific gravity ranging approximately from 1.022 to 1.038 at temperatures between 20 and 25 °C. It demonstrates solubility in alcohol but is not soluble in water, influencing its application in aromatic formulations. Benzoin resin replacer is typically sourced or manufactured to replicate the characteristic scent of natural benzoin resins while offering enhanced stability and consistent quality. Its properties and derived profile are referenced in controlled vocabulary sources such as PubChem for chemical background and identification.

This compound is primarily applied as a laboratory-engineered replacement for natural benzoin absolute, which is extracted from the resin of Styrax species trees. Benzoin resin replacer offers similar balsamic odor qualities and is used extensively in fragrance compositions where a vanilla-like balsamic note is desired. It provides long-lasting scent substantivity, measured at approximately 400 hours, which is beneficial in perfumery for creating enduring aroma profiles. Regulatory standards such as the IFRA (Global) Code of Practice provide guidance on use levels and recommended applications, though current notifications indicate it is not recommended for flavor use. Its versatility as a benzoin absolute substitute enables its incorporation into multiple fragrance product types, delivering characteristic warmth and sweetness.

Benzoin resin replacer exhibits physical properties that make it suitable for use in fragrance formulations. It has a specific gravity generally around 1.022 to 1.038 at 20 to 25 °C, indicating a moderately dense liquid phase relative to water. Its refractive index falls between 1.445 and 1.456 at 20 °C, illustrating its optical density, which can assist in quality control and purity verification. The compound has a flash point of 93 °F (approximately 34 °C), suggesting moderate volatility and flammability that formulators must consider in handling and storage. Its solubility in alcohol but insolubility in water affects its blending capabilities, favoring alcohol-based carriers commonly used in perfumery. These properties collectively influence its stability, sensory delivery, and compatibility in fragrance compositions.
