What is Terrasol?

Terrasol FCC is the FCC-grade form of 2-Ethyl Fenchol, a highly diffusive synthetic alcohol belonging to the fenchyl alcohol family. It possesses a rigid tricyclic structure that contributes to its long-lasting earthy-mineral signature, often described as astonishingly true-to-nature.

While older descriptions occasionally refer to an “ambergris” nuance, its primary value lies in its wet-earth, mineral-patchouli effect. The material performs well as a standalone note or in tandem with other earthy, rooty, or green molecules like vetiverol, geosmin, or moss derivatives.

Olfactory Profile and Perfumery Applications

Terrasol is unique in offering a realistic wet-soil signature that functions in both artistic and functional perfumery. Its scent is immediately recognizable as humid, rain-soaked earth, and it integrates exceptionally well in:

  • Rain/atmospheric accords: Core element in stormy, petrichor, or vegetal-earthy effects

  • Patchouli and vetiver enhancers: Boosts the naturality and realism of rooty facets

  • Orientals and fougères: Adds complexity to moss, oakwood, or ambery blends

  • Modern florals and aquatic bases: Brings grounding contrast to transparent top notes

  • Functional perfumery: Used for its stability in oxidizing environments (e.g., bleach systems)

Flavor Profile and Use

  • Flavor Profile: Green, woody-rosy, earthy

  • Use Level in Flavorings: 0.1–10 ppm

  • Application: Enhances berry flavors (especially raspberry, blackberry) with subtle earthy-rosy nuance

  • Regulatory Status: FEMA 3491 – approved for limited food use

Regulatory and Safety Overview

  • IFRA: Compliant within standard use levels; not subject to IFRA restrictions as of the 51st Amendment

  • EU Allergens: Not included among the 26 mandatory declarable substances

  • FEMA GRAS: FEMA 3491 – approved for flavor use under controlled conditions

  • ECHA (REACH): Registered and not classified as hazardous

  • Toxicology: Low toxicity; not classified as sensitizer or respiratory hazard

  • Environmental Profile: Not classified as PBT or vPvB
