What's in the formula?

Each Sensitive Laundry Sheet contains 11 ingredients in a pre-measured paper-thin sheet that dissolves in the wash. The formula combines surfactants for everyday cleaning, three enzymes for stain breakdown, a water softener, bicarb soda, kaolin, glycerin, and a dissolvable polyvinyl alcohol carrier, with a small amount of water remaining from manufacture. Glycerin is vegetable-derived from plant oils, plant-sourced (supplier confirmed). There's no fragrance, no dye, no chlorine bleach, no optical brighteners, and no phosphates. Sheets are Dermatest certified for sensitive skin.

Tap any ingredient below to see what it does and why it's in the sheet.

Aqua (water)

Water remaining from manufacturing. Keeps the sheet flexible enough not to crack in storage.

Sodium dodecyl sulfate

A surfactant. Lifts grease, oil, and particulate dirt from fabric so it rinses away during the wash.

Polyvinyl alcohol

The sheet itself. A water-soluble film that holds the formula together in the pack and dissolves cleanly in the drum.

Kaolin

A fine mineral clay. Gives the sheet body and adds gentle scrubbing action to help loosen particulate soils.

Alcohols C12-14 ethoxylated

A surfactant. Helps tackle oily and greasy stains, including in hard water.

Glycerin

A humectant. Keeps the sheet soft and flexible so it doesn't crack or go brittle in the pack. Vegetable-derived from plant oils, plant-sourced (supplier confirmed).

Trisodium citrate

A water softener. Binds calcium and magnesium so hard water doesn't get in the way of cleaning.

Sodium bicarbonate

Bicarb soda. Helps neutralise odours and gently supports stain removal in the wash.

Cellulase

An enzyme. Targets plant-based soils like grass, food residue, and fibre dirt. Also helps reduce fabric fuzz and pilling over time.

Protease

An enzyme. Targets protein-based stains like blood, sweat, egg, and dairy.

Amylase

An enzyme. Targets starch-based stains like pasta sauce, gravy, and baby food.


Where can I find the Safety Data Sheet?

The Safety Data Sheet for Sensitive Laundry Sheets is a regulatory document used for workplace safety and emergency reference. It includes hazard classification, first aid measures, handling and storage guidance, and disposal information in a standardised 16-section format. Most customers won't need it. For everyday questions about ingredients or how to use the sheets, the section above and the product page are simpler. Tap to expand the SDS card and download the PDF.

✓ Access Safety Data Sheet (SDS)

Heads up: the Safety Data Sheet is a regulatory document written for workplace safety officers, first responders, and waste handlers. It uses chemistry and hazard classification language and isn't designed as a customer FAQ.

If you're asking about ingredients, sensitivity, or everyday use, the section above and the product page will be more useful.

Still need the SDS? It's a standardised 16-section PDF covering hazards, first aid measures, handling and storage, and disposal.
