A superior, high-impact version of Iso E Super. Higher in the desirable gamma isomer than Iso E Super, Timbersilk has also been enhanced with another high-impact material from IFF. Exceptional in candles but excellent in almost all applications. Description from the IFF Compendium: Soft and spacious natural woody note with refined facets of cedar and amber. Timbersilk is an excellent base to produce strength, volume and toughness for most end-use applications.
