However, ALS comes from the same family of chemicals that Sodium Lauryl Sulphate (SLS) belongs to, and carries the same potential health risks: These include, possible genetic mutations, irritation to the skin and eyes, cancer, toxicity, neurotoxicity, ecotoxicology, endocrine disruption, cellular or biochemical alterations, and reproductive toxicity.
In 1983, a report by the Cosmetic Ingredient Review stated that SLS and ALS sulfate "appear to be safe in formulations designed for discontinuous, brief use followed by thorough rinsing from the surface of the skin. In products intended for prolonged use, concentrations should not exceed 1%.". However, this doesn't adequately address the accumulation phenomenon: the medium and long term build up of toxins in our bodies. Our bodies naturally detox themselves in a number of ways, including through the liver and kidneys. However, when we pollute it with unnatural chemicals, we run the risk that our bodies cannot cope. The accumulation can result in some of the health risks highlighted above.
Products in which ALS is frequently found include: Body washes, shampoo, face cleansers, liquid soaps, treatment for acne, hair colourant, bleaching, relaxers, shaving cream, scalp treatment, bubble bath, foot treatment, and anti ageing products. Personally, I always avoid products with ALS, and recommend that others do the same, especially the very young or old.
