What are the ingredients of Dishwashing Liquid?Updated a day ago

TL;DR: Dishwashing Liquid works like this. Two surfactants lift grease, three enzymes (protease for protein, amylase for starch and lipase for fats and oils) break down cooked-on food, glycerin for hand-feel, calcium chloride for hard water, sodium chloride and sodium formate hold the liquid and its pH steady, and a two-part preservative covers the 12-month shelf life. No added fragrance, no dyes. Made in Australia.

What are the ingredients of Dishwashing Liquid?

Koh Dishwashing Liquid contains Aqua, Sodium Laureth Sulfate, Cocamidopropyl Betaine, Sodium Chloride, Sodium Formate, Glycerin, Protease, Amylase, Lipase, Methylchloroisothiazolinone, Methylisothiazolinone and Calcium Chloride. That is purified water filtered to remove the minerals that spot glassware, two surfactants for lifting grease, three enzymes (protease for protein residue, amylase for starchy food and lipase for fats and oils), glycerin as a humectant for hand-feel, calcium chloride for hard water, sodium chloride and sodium formate to hold the liquid and its pH steady, and a two-part preservative for the 12-month shelf life. No added fragrance, no dyes, made in Australia. See what each ingredient does below.

Every ingredient, listed in full. Made in Australia.

AquaWater

Purified to remove the minerals that spot glassware.

Lifts grease off plates so water carries it away, and makes the suds.

Cocamidopropyl BetaineSurfactant

Helps dishes rinse clean rather than streaky.

Sodium ChlorideSalt

Sets how thick the liquid is, so it pours in a controlled stream.

Sodium FormateStabiliser

Holds the pH steady across the shelf life.

GlycerinHumectant

Offsets the drying feel of hot water on your hands.

ProteaseEnzyme

Breaks down protein, like egg, cheese and milk film.

AmylaseEnzyme

Targets starchy food marks like pasta sauce, gravy and baby food.

LipaseEnzyme

Breaks down fats and oils, like a greasy roasting tin.

MethylchloroisothiazolinonePreservative

Keeps the formula stable for 12 months.

MethylisothiazolinonePreservative

Works as a pair with the preservative above.

Calcium ChlorideStabiliser

What certifications does it hold?

Koh Dishwashing Liquid holds four current independent certifications. Good Environmental Choice Australia (GECA) certified. Sensitive Choice approved by the National Asthma Council Australia. Dermatest tested for skin tolerance. Eczema Association of Australasia recognised.
