What's in Loo Cleaner Tabs?

Koh Loo Cleaner Tabs contain 15 ingredients. The active cleaning agents are sodium bicarbonate (gentle abrasive and deodoriser), citric acid (descaler), sodium percarbonate (oxygen bleach for whitening and deodorising), sodium carbonate (alkaline cleaning booster), DL-tartaric acid (descaler), sodium lauryl sulfate (surfactant for grease and soil), and three enzymes (protease for protein stains, amylase for starch residues, lipase for fats and oils). The remaining ingredients support tablet structure and dissolution: itaconic acid copolymer, magnesium stearate, polyvinylpolypyrrolidone, croscarmellose sodium, microcrystalline cellulose, polyethylene glycol 4000, and PVOH (polyvinyl alcohol) which is also used as the outer wrapper film.
