Full ingredient breakdown

Sodium Bicarbonate

Gentle abrasive and deodoriser. Fizzes with citric acid to loosen stains and dissolve limescale.

Citric Acid

Descaler and stain remover. Reacts to fizz, dissolves mineral deposits, and adjusts pH for optimal cleaning.

Itaconic Acid Copolymer

Dispersant and water softener. Prevents soil redeposition and helps actives cling for longer contact.

Sodium Lauryl Sulfate

Surfactant. Lowers water tension to break down grease, disperse soils, and boost overall cleaning.

Sodium Percarbonate

Oxygen bleach. Releases hydrogen peroxide to whiten stains, deodorise, and disinfect.

Protease and Amylase

Enzymes that dissolve protein and starch stains for deeper, targeted cleaning.

Lipase

Enzyme that breaks down fats and oily residues for a grease-free bowl.

Magnesium Stearate

Lubricant and stabiliser. Keeps the tablet intact during storage and controls the dissolution rate.

Polyvinylpolypyrrolidone

Binder and solubility enhancer. Holds ingredients together and ensures even tablet breakup.

Croscarmellose Sodium

Disintegrant. Swells on contact with water to break the tablet apart for rapid ingredient release.

Microcrystalline Cellulose

Filler and binder. Gives the tablet structure and regulates how quickly it dissolves.

DL-Tartaric Acid

pH adjuster and descaler. Lowers pH to dissolve limescale and enhance other ingredients.

Sodium Carbonate

Water softener and alkaline booster. Neutralises acids and improves surfactant performance.

Polyethylene Glycol 4000

Binder and release controller. Maintains tablet shape and enables gradual, consistent dissolution.

PVA (Polyvinyl Alcohol)

Water-soluble binder. Keeps the tablet intact and then dissolves cleanly to release all actives. Also used as the outer wrapper film. Learn more about PVA and the environment
