What makes Benzaldehyde Dimethyl Acetal distinctive
Benzaldehyde's almond, softened and made floral by the acetal.
Where the descriptions disagree: JECFA names an almond note in its sweet floral description; Sigma-Aldrich does not mention almond, and The Good Scents Company lists it only among several minor descriptors.
How Benzaldehyde Dimethyl Acetal is used
Used for a softer, more stable almond note in floral and gourmand accords.
Typical role: modifier (used in small amounts to change the character of a blend).
How Benzaldehyde Dimethyl Acetal differs from similar materials
- Phenylacetaldehyde Dimethyl Acetal
- Both are dimethyl acetals of aromatic aldehydes; benzaldehyde's is sweet floral-almond, phenylacetaldehyde's green and hyacinth-like.
Each difference compares the published descriptions of the two materials. Smell varies with grade, supplier and dilution; compare them side by side on blotters before substituting one for another.
