Effect in a formula
Useful for connecting citrus-peel effects with rose, particularly in citrus, rose and aldehydic compositions. It gives aldehydic blends a diffuse, waxy-soapy character and reinforces the fatty petal aspect of rose accords. In citrus formulas, it helps the opening remain perceptible beyond the initial contribution of expressed oils.

Behaviour and performance
- Tenacity
- The page reports 276 hours of blotter substantivity, attributed to TGSC. The test dilution, solvent and endpoint are not specified.
Diffusion, tenacity and note impact are not combined into a single performance score.
Dissolving and diluting
- Solvents
- Ethanol, DPG and IPM are reported to give clear solutions readily. The material is described as insoluble in water.
- Working dilution
- Use a 1% stock for formulation work and a 0.1% dilution for smelling; ethanol is the page's primary listed solvent, with DPG and IPM also listed. A separate use section permits either 1% or 10% working solutions.
- Appearance
- Liquid, ranging from colourless to a faint yellow tint.
Practical tip: Dose cautiously: excessive addition can make the blend overly fatty and soapy, with a rancid tendency. Limit oxidation by protecting stock from heat, light and air, and use opened material promptly. The supplier also recommends a dedicated pipette and mentions BHT as an oxidation-control aid, without giving an addition rate.
