In short
Timbersilk is an IFF woody-amber material, a grade of the molecules in Iso E Super with a different isomer balance. It is smooth and warm, with cedarwood facets.
What Timbersilk smells like
Fraterworks describes Timbersilk as effectively the same material as Iso E Super but with a different balance of isomers, and gives its odour as a smooth, warm woody-amber character with refined cedarwood facets; its laboratory notes list woody, amber, ambergris, floral and warm.

What makes Timbersilk distinctive
Iso E Super's molecules in a different balance, read as smoother and warmer.
How Timbersilk is used
Used as a woody-amber backbone and blender in the way Iso E Super is, where a smoother, warmer character is wanted.
Typical role: backbone (used in large proportions as a structural material of an accord); blender (smooths the joins between other materials).
How Timbersilk differs from similar materials
- Iso E Super
- Fraterworks calls Timbersilk effectively the same material as Iso E Super with a different isomer balance, smoother and warmer, with refined cedarwood facets. (compared directly by a cited source)
An asterisk marks a difference that a cited source states directly. The others compare the published descriptions of each material. Smell varies with grade, supplier and dilution; compare them side by side on blotters before substituting one for another.
Formulation considerations
Sold under the CAS number of Iso E Super, of which it is a different isomer balance; the two are separate products.

No CAS number is shown. The identity of Timbersilk is taken from documentation by IFF, Fraterworks; it is a grade of the same octahydro-tetramethyl-naphthalenyl ethanone isomers as Iso E Super, with a different isomer balance, sold under Iso E Super's CAS number, so that number cannot identify it and is not published for this record. Without a verified number there is no formula, molecular weight or structure drawing either.
