Laundry Detergent Bulk Refill

Two years in the making. One pouch that changes laundry forever.

The Laundry Detergent Bulk Refill by Guests on Earth is a breakthrough concentrate that refills your reusable bottle twice — tackling 150 loads per pouch with next-generation biosurfactant technology that outperforms conventional detergents.

Why It Works Differently

Most detergents are soap-heavy: they try to absorb stains into the fabric. Ours does the opposite.

• Lifts stains like a magnet — our proprietary technology pulls stains off fibres rather than pushing into them.
• Keeps dirt suspended in water — preventing redeposition, so your brights stay brighter and whites stay whiter, wash after wash.

First-to-Market Biosurfactants

We use the highest concentration of glycolipids available in a consumer laundry product — delivering deep, fabric-safe cleaning with a lower carbon footprint than the glucosides found in traditional detergents.

Enzyme Technology, Corrected

Enzymes are powerful stain-breakers, but standard blends can degrade natural fibres over time. Our corrected enzyme blend delivers exceptional cleaning performance without compromising the long-term integrity of your textiles.
