2-Tridecanone 959922 (Firmenich®)

A leafy, herbal odour with substantial fatty and wax-like texture, softened by a secondary fruit nuance. Rue and coconut associations give it an unusual position between green and creamy odour families, with additional suggestions of blue cheese and creamy mushroom. The supplier describes persistence over several hours, but does not document a distinct opening-to-dry-down sequence on blotter or provide a projection assessment.

Provides persistent, wax-like body to leafy and vegetal compositions, complementing more fleeting green ingredients. It supports naturalistic fig and tomato-leaf accords, introduces herbal contrast into creamy themes, and contributes a fatty petal effect in florals. Coconut, dairy and herbal accords can use its richness for added depth.

The supplier gives 0.1–1% of the fragrance concentrate as the customary range. Separately, its laboratory notes suggest 0.1–2% in finished fragrance for coconut, fig and herbal themes, with trace additions for fatty dairy effects in gourmands; these percentages refer to a different formulation basis. This is formulation guidance, not an IFRA limit.

No confirmed manufacturer use level for this exact product.

Tenacity

Reported persistence is moderate, extending over hours. The page identifies its tenacity assessment as volatility-based rather than supplying a measured blotter duration or test protocol.

Diffusion, tenacity and note impact are not combined into a single performance score.

Solvents

Water solubility is negligible. After gentle warming to liquefy the material, the supplier reports clear solutions with ethanol, DPG or IPM.

Working dilution

Use a 10% stock for formulation work and a 1% dilution for odour assessment. Ethanol, DPG and IPM are the supplier's listed solvent options.

Appearance

The liquid ranges from colourless to a faint yellow tint. It can crystallise or become solid under ambient or cooler conditions; the stated melting point is approximately 28 °C.
