Performance is in our nature.

DuPont Tate & Lyle Bio Products provides natural and renewably sourced ingredients that enhance product performance. We offer solutions for a wide variety of markets and applications through our bio-based performance brands, Susterra® and Zemea®.



When performance matters, choose Susterra® propanediol—the pure, bio-based, petroleum-free diol. Susterra® propanediol is the building block that delivers high performance in a variety of applications, from polyurethanes and unsaturated polyester resins to heat-transfer fluids.



Zemea® propanediol is the multifunctional, preservative-boosting humectant and ingredient that delivers high performance in a variety of consumer applications, from cosmetics and personal care to food, flavor, and pharmaceuticals, and laundry and household cleaning.
