Simply Clean Detergent is an environmentally safe formula that is also extremely efficient. It is formulated with biodegradable surfactants that, unlike phosphates, do not react with calcium ions present in hard water. Because of this, Simply Clean works equally well in hard water. A suspending agent, Cellulose Gum (derived from plants and also a food additive), prevents loosened dirt from returning to clothes. Other ingredients include ethanol and a non-poisonous optical brightener. Ethanol is used for removing oily soils and stabilizing the detergent system while the optical brightener (less than 0.1%) emits light thus making fibers look brighter. Ingredients: Water, ethoxylated fatty alcohol (from coconuts), ethyl alcohol, sodium citrate, coco-glycoside (from coconut oil and fruit sugars), cellulose gum, cocoamidopropyl betaine (from coconut oil), sodium carboxymethylcellulose, preservative (0.5%), whitening agent (0.05%).
