✓ What's not in there
A short list of what Dishwashing Liquid leaves out, all relevant for households with sensitive skin.
11 ingredients, listed in full.
AquaWater
Purified to remove minerals, so the formula works the same in hard and soft water.
Sodium Laureth SulfateSurfactant
Lifts grease from dishes and helps water spread evenly.
Cocamidopropyl BetaineSurfactant
Helps the foam hold up during the wash and rinses cleanly.
LipaseEnzyme
Targets fats and oils, the residue that's hardest to rinse off pans and roasting trays.
ProteaseEnzyme
Targets protein residue like dried egg, baked-on dairy, meat and fish.
GlycerineHumectant
Helps stop hands drying out during frequent washing up.
Calcium ChlorideStabiliser
Helps the formula work consistently in hard-water areas.
Sodium ChlorideSalt
Sets the thickness so the liquid pours comfortably.
Sodium FormatepH buffer
Keeps the formula at a steady pH 6.5 through its shelf life.
MethylchloroisothiazolinonePreservative
Keeps the formula stable for 12 months unopened.
MethylisothiazolinonePreservative

What about certifications?
✓ Dermatest tested
Dishwashing Liquid is Dermatest tested for skin tolerance, an independent lab assessment of skin compatibility. Also septic and grey water compatible when used as directed, cruelty-free, fragrance-free and 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.
11 ingredients. Dermatest tested. pH 6.5. Septic compatible when used as directed, fragrance-free.
