Tap any ingredient below to see what it does and why it's in the box.
Aqua (deionised water)
The base of the liquid. Purified water with minerals removed so the formula stays clean and consistent across hard and soft water areas.
Sodium laureth sulfate
A surfactant. Lifts grease from dishes and helps water spread evenly across surfaces.
Cocamidopropyl betaine
A coconut-derived surfactant. Helps the foam hold up during the wash and rinses cleanly off dishes.
Lipase
An enzyme. Targets fats and oils, the residue that's hardest to rinse off pots, pans, and roasting trays.
Protease
An enzyme. Targets protein-based food residue: dried egg yolk, baked-on dairy, meat, and fish.
Glycerine
A humectant. Helps protect hands from drying during frequent washing up. Vegetable-derived from plant oils, plant-sourced (supplier confirmed).
Calcium chloride
Helps the formula perform consistently in hard-water areas where mineral content can affect cleaning.
Sodium chloride
Common salt. Adjusts thickness so the liquid stays at a comfortable pour consistency.
Sodium formate
A pH buffer. Keeps the formula at a stable pH 6.5 throughout its shelf life.
Preservative blend (methylchloroisothiazolinone + methylisothiazolinone)
A two-ingredient preservative system that keeps the formula stable for 12 months unopened. Common in water-based formulations to prevent microbial growth.
If you have a specific concern about an ingredient or sensitivity, the box also carries the country of origin and cert details.
What about certifications?
✓ Dermatest tested
Dishwashing Liquid is Dermatest tested for skin tolerance, an independent lab assessment of skin compatibility. Also food-grade, pet-safe, family-safe, septic safe, grey water safe, cruelty-free, fragrance-free, dye-free.
Where can I find the Safety Data Sheet?
✓ 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.
10 ingredients. Dermatest tested. pH 6.5. Septic safe, fragrance-free.
