About this material
Vanirome
Slightly more chocolaty than Vanillin, but much more powerful.
Outstanding tenacity. The power is demonstrated in dilutions of this material.
Often used to substitute Vanillin. The sweetness of Vanilla is maintained although there is likely to be a loss in the physical fixation effect.
Vanirome is a powder in its pure form. Here we provide a pre-dissolved solution in DPG for your convenience.

Generic regulatory reference only. This is not a supplier allergen declaration, measured composition, allergen-free claim or finished-product labelling assessment.
Raw undiluted material reference. These data refer to the named active material, not the complete supplied dilution. A raw-material IFRA ceiling is not a use level for this diluted product. The assessor must account for the actual concentration, carrier and all other formula contributions.

Documentation Supply PolicyIFRA formulation guide
Generic reference only — not an IFRA certificate, compliance decision or use recommendation. The Responsible Person and qualified safety assessor must assess the actual finished formula using current applicable IFRA Standards, supplementary documentation where available and the CPSR.
Raw undiluted material reference. These data refer to the named active material, not the complete supplied dilution. A raw-material IFRA ceiling is not a use level for this diluted product. The assessor must account for the actual concentration, carrier and all other formula contributions.
Source: 51st Amendment overview, held source checked 2026-10-21. Bundle 2026-10-27. Individual Standards prevail over the overview.
No direct IFRA overview entry matched the recorded CAS in this held dataset. This does not mean unrestricted use, absence of relevant Standards or compliance. Constituent restrictions may still apply.

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.
