Econo 12 x 750ml Thick Bleach is a bleach product typically used for cleaning and disinfecting surfaces. Bleach itself is primarily composed of water and sodium hypochlorite, with other additives for thickening and stabilization. It does not contain alcohol as a primary ingredient. Instead, its main active ingredient is sodium hypochlorite, which is a chlorine-based compound. However, bleach products may contain small amounts of other chemicals for stabilization or fragrance, but alcohol is not a typical component. It's always a good idea to check the specific ingredients list provided by the manufacturer to confirm the composition of the product.
