Vanillin is the emblematic gourmand molecule, delivering a sweet, creamy vanilla note with a soft, slightly powdery warmth. Even at low levels, it rounds rough edges, adds a cushioned “creaminess,” and imparts the comforting warmth that makes formulas feel complete and inviting.

In fragrance compositions, Vanillin works from mid to base with good diffusion and longevity. It adds balsamic depth, enhances comfort, and often serves as a backbone for amber–woody–gourmand accords. At appropriate dosage, it helps fix and extend the drydown while smoothing sharp facets for a more harmonious overall profile.

Widely used across fine fragrance, body care, and home fragrance. Note: Vanillin can discolor bases toward yellow–brown in soap/candles and alkaline systems; stability testing is recommended before scale-up. Because it can crystallize at room temperature, pre-dissolve in a suitable solvent to aid accurate weighing and even dispersion.

Suggested use: prepare a 10–20% predilution in ethanol, DPG, or TEC for precise handling. Use at low levels for “smoothing” (approx. 0.1–0.5% on concentrate) or higher for a clear gourmand impact (typically 1–3%, depending on formula and application base). Always run bench tests to optimize dosage, stability, and color.

Key technical data: Vanillin (CAS 121-33-5), white to off-white crystals, typical purity ≥99%, odor profile vanilla—sweet—creamy—balsamic. Low water solubility; soluble in ethanol, propylene glycol/DPG, and TEC. Store tightly closed in a cool, dry place, away from moisture and direct light.
