6:2 Fluorotelomer Sulfonate Storage — PFOS-Replacement Fluorosurfactant Tank Selection

Storing 6:2 Fluorotelomer Sulfonate? Start Here

This is a fluorosurfactant (a PFOS replacement) supplied as a 10–30% water solution. Chemically it's mild — a surfactant, not an aggressive acid or oxidizer — so a standard poly tank handles it easily. One practical note: PFAS chemistries are being phased out of many uses, so treat inventory as transitional.

Can you store it in a poly tank? Yes.

The 10–30% aqueous solution is fully compatible with HDPE/XLPE and polypropylene — the mildness of the water-plus-surfactant chemistry makes material selection easy. Standard gaskets (Viton or EPDM) per the chart.

The safety that actually matters

• PFAS regulatory trajectory — usage is being restricted; plan for transition and proper disposal rather than long-term stockpiling.
• Standard surfactant handling: gloves, eye protection, vent, containment.

Common questions

Is it hard on a poly tank?

No — it's a mild aqueous surfactant. HDPE/XLPE or PP all work.

Anything special?

It's a PFAS chemistry being phased out — treat stock as transitional and handle disposal per current rules.
