Are Laundry Detergent Sheets Safe? Natulim's Ingredients Explained
"Eco" claims are easy to make. So we went through Natulim's published ingredient list line by line to see what's really in the sheets.
The ingredients, in plain English
- Polyvinyl alcohol (PVA) — the water-soluble film that holds everything together. Same material as detergent pods.
- Glycerol — plant-derived; helps cleaning and softening.
- Betaine — a mild surfactant known for being gentle on skin.
- Sodium bicarbonate — baking soda; balances pH and freshens.
- Sodium citrate — softens water; the standard phosphate-free alternative.
- Sodium dodecyl sulfate, alpha-olefin sulfonate, alcohol ethoxysulfate — the surfactants that lift oil and dirt. Natulim states they're biodegradable under EU Regulation 648/2004.
- Kaolin and starch — form the body of the sheet.
- Fragrance — Lavender and Floral only; the Natural version is unscented.
Is it safe for skin?
Natulim says the sheets are tested by Dermatest and contain no endocrine disruptors. If you have eczema or very sensitive skin, or you wash baby clothes or cloth nappies, choose the unscented version — fragrance is the most common irritant in any detergent.
The PVA question
PVA dissolves in water, but whether it fully biodegrades in real wastewater-treatment conditions is debated. Some researchers argue a share may pass through treatment plants; manufacturers and other studies say it breaks down under the right conditions. It's the same film used in almost all detergent pods, so sheets aren't worse than pods on this point — but if your goal is zero synthetic polymers, no sheet or pod format fully gets you there.
What isn't in it
No phosphates (banned in EU household detergents), no optical brighteners listed, and no plastic bottle.
Bottom line
Natulim publishes a clear ingredient list, which is more than many brands do. For most households the sheets are a safe, lower-plastic choice. The unscented version is the safest pick for sensitive skin.
