Sulphates, also known as sulfates, are a common ingredient in many industrial and household products. They are salts of sulphuric acid and are widely used for their cleaning and foaming properties. However, due to their potential harm to the environment and human health, many people prefer to use alternative products without sulphates. Some popular synonyms for sulphates are SLS (sodium lauryl sulphate), SLES (sodium laureth sulphate), ALS (ammonium lauryl sulphate) and ALES (ammonium laureth sulphate). These alternatives are milder and less harmful to the skin and hair, making them the perfect solution for those looking for sulphate-free products.
