Ethyl Vanillin is a high-impact vanillic aldehyde celebrated for its warm, creamy vanilla facets with a gentle balsamic undertone. Compared with standard vanillin, it reads sweeter, deeper, and more distinctly gourmand, rounding out amber accords, dairy/caramel nuances, cocoa facets, and modern warm structures.

On skin and in base-heavy formats, Ethyl Vanillin adds body, smoothness, and a plush “soft-focus” effect, taming rough edges and extending drydown. It excels as a foundation note with strong diffusion and long-lasting, cozy sweetness-ideal for oriental/amber and gourmand signatures, fine fragrance, soap bars, and scented candles.

Technically, Ethyl Vanillin appears as white to pale-yellow crystals, soluble in ethanol and propylene glycol, sparingly soluble in water, and prone to discoloration in strong alkaline systems or amine-rich bases. Use sparingly due to its power; typical working levels are ~0.05–1% of the formula (vary by solvent system and desired impact). Build in small increments to avoid masking other notes.

Reference data: CAS 121-32-4; molecular formula C₉H₁₀O₃; FEMA 2464. Widely used across fine fragrance, personal care, household air care, and-where permitted-flavor applications. For cosmetics and skin-contact products, follow current safety guidance/IFRA restrictions and verify stability and color fastness in your actual base.

Store in a cool, dry place away from light and humidity to preserve purity and olfactory performance. SCENT can provide technical documentation and basic compounding guidance tailored to your lot upon request.
