Biobased farnesene finds tacky new application


In Pennsylvania, Total subsidiary Cray Valley has launched tackifying resins using biobased farnesene produced by Amyris.

Tackifying resins are traditionally derived from trees, citrus fruit sources, or petroleum-based feedstocks. Thus, they are subject to cost and supply instabilities, in the case of petroleum-based sources, or natural variabilities, in the case of pinene and limonene.

Cray Valley’s Wingtack family of tackifying resins is manufactured with piperylene, a volatile hydrocarbon that is a byproduct of ethylene production. New technology has enabled the company to swap 30% of the piperylene with farnesene while maintaining comparable performance, particularly in hot melt and hot melt pressure-sensitive adhesives.

“According to independent market research firm,, the global tackifier market is projected to reach $3.56 billion by 2020,” Amyris says. “This poses a large opportunity for renewable farnesene-based tackifiers and Amyris believes it can access a large market share as its product applications within the space achieve commercial scale.”
