How laundry detergent sheets work
A detergent sheet (also called a laundry sheet, laundry strip or eco sheet) is a full dose of concentrated laundry detergent that has been dried and pressed into a thin strip. A water-soluble binder holds the cleaning ingredients together, so the sheet keeps its shape in the pack and releases the detergent as soon as it meets water.
Spot Detergent Sheets dissolve in under 60 seconds, in cold, warm or hot water, so nothing is left in the drum or on your clothes. The cleaning agents then do the same job as the surfactants in a capful of liquid: they lift dirt and oil from fabric and rinse away.
What is in a detergent sheet?
Our sheets have nine ingredients: Sodium Dodecyl Sulfate, Decyl Glucoside, Cocamidopropyl Betaine, Glycerol, Fatty Alcohol Polyglycol Ether, Water, Polyvinyl Alcohol, Trisodium Citrate, Trilon M. The formula is plant-based, free of parabens, phosphates, 1,4-dioxane and added dyes, hypoallergenic and dermatologist tested.
Every sheet needs something to hold it together. In ours, that is polyvinyl alcohol, a water-soluble polymer. Our ingredients page explains what each ingredient does.
Why people switch from liquid and powder
- No plastic jug. Spot ships flat in a recyclable paper envelope.
- No measuring or spills. Each sheet is perforated, so half a sheet handles a small load.
- Light and compact. A pack fits in a drawer, a carry-on bag or an RV cupboard, and no liquid means no airport liquid limits.
- Easier to lift. People who find a heavy jug hard to carry often switch for this reason alone.
What to keep in mind
- Sheets are a different format, not a different kind of chemistry. For a stubborn stain, pre-treat it the way you would with any detergent.
- Place the sheet in the drum with your clothes, not flat against the washer wall, so it dissolves evenly.
- Spot comes in one light scent, Fresh Linen.
