What is the Hand Wash Pump made of?

The Hand Wash Pump bottle is high-density polyethylene (HDPE) with a soft-touch matte finish and 50 per cent recycled plastic content, and it carries the Reloop additive in the plastic compound. The head is polypropylene (PP) with a twist-lock collar and no metal spring. Free from BPA, PVC and phthalates.

The bottle and the head are both built for repeated refilling over the long term, not single use. The bottle refills from the Sensitive Hand Wash refill box.

What is the Reloop additive?

Reloop is an additive built into the bottle's plastic compound at manufacture. It doesn't change how the bottle performs or how long it lasts in use. In a microbe-rich environment such as landfill or soil, the additive is designed to attract microbes that break down the plastic's molecular structure over time. Test methods for this are still debated.

Reloop is an additive built into the bottle's plastic compound at manufacture. It doesn't change how the bottle performs, or how long it lasts on your basin.

In a microbe-rich environment such as landfill or soil, the additive is designed to draw microbes to the plastic so they can break down its molecular structure over time. That's what the technology is intended to do.

Unlike plastics engineered to break down while you're still using them, a Reloop bottle is built to stay stable and fully functional for its whole working life. The additive only responds to those disposal conditions.


How long does the Hand Wash Pump last?

The Hand Wash Pump is designed for long-term repeated use, and each press dispenses 2 ml. Rinse the nozzle occasionally with warm water to clear product buildup inside the head. If the pump goes sluggish or clogs, flushing it with warm water usually clears it.
