About this material
Slightly more chocolaty and much more powerful than Vanillin, making it a cost-effective alternative.
Outstanding tenacity.
The power of Ethyl Vanillin is demonstrated in dilutions of this material.
Often used to substitute Vanillin where discolouration occurs. Discolouration can be reduced and the sweetness of the Vanilla is maintained although there is likely to be a loss in the physical fixation effect.
Sold here in its pure form.

This molecular reference matches the catalogue’s recorded CAS and formula. It does not confirm the supplied grade, purity, stereochemistry, isomer proportions, composition, impurities or unlisted constituents.
Fragrance allergen reference
Generic regulatory reference only. This is not a supplier allergen declaration, measured composition, allergen-free claim or finished-product labelling assessment.
Raw-material reference based on recorded CAS numbers. A CAS match identifies a reference entry; it does not verify the supplied grade, composition, purity or finished-product compliance. Naturals, bases and mixtures require composition review.

No direct listed-entry CAS match in this jurisdiction’s held reference set. This does not mean the material is allergen-free. Constituents, grouped entries and natural-material composition may require further review.
Finished-cosmetic declaration thresholds: greater than 0.001% leave-on; greater than 0.01% rinse-off. Apply the current target-market rules to the actual complete formulation; no concentration is inferred here.

Creative ideas to explore
Creative directions, not tested formulas.Sweetness and grain
With sandalwood and dry wood notesExplore a gourmand sketch framed by wood rather than more sweetness. Compare a creamy wood direction with a drier one, deciding whether the material works best as the centre of the idea or as a softer background.
Citrus confection
With bergamot and a peel directionTry a contrast between the gourmand character and a citrus opening. Compare a peel-led version with a sweeter reference, looking for a balance that evokes your intended confection without turning every part of the composition sweet.
Petal cream
With rose and a soft floral accordSet the gourmand material beside a familiar flower for a petal-and-cream concept. Evaluate the floral reference and the sweeter variation together, then choose whether the result should remain recognisably floral or move towards a dessert impression.
