Adhance

Polyalkyleneoxide‑modified heptamethyltrisiloxane (CAS 67674‑67‑3) is a high‑performance, non‑ionic organosilicone surfactant designed for superior agricultural performance. Acting as a powerful “super‑spreader” and tank‑mix enhancer, it combines a hydrophobic silicone backbone with hydrophilic polyalkyleneoxide chains to drive surface tension down to ultra‑low levels enabling rapid and uniform droplet spread.

This enhanced coverage significantly improves pesticide uptake, allowing dose reductions of 20–30% without compromising efficacy. Its spreading efficiency also lowers water requirements by up to 50%, reducing spray time, energy consumption, and equipment strain. The formulation performs exceptionally well on hard‑to‑wet surfaces—such as waxy, hairy, or vertical leaves (onion, cabbage, broccoli, banana)—where conventional sprays fail to adhere.

Physically, it is a clear, colorless to pale amber liquid with low viscosity, offering easy handling. It is readily dispersible in water and highly compatible with most organic solvents, ensuring seamless integration across formulations.
