Common Harmful Chemicals in Lice Treatment
Chemical Name
Why it’s harmful
Sodium laureth sulfate, derived from ethoxylated lauryl alcohol, is a surfactant used in sudsy products like toothpaste, detergents, and shampoos. While it acts as a cleansing and emulsifying agent, it can sometimes contain toxic impurities such as 1,4-dioxane. This chemical has raised health concerns due to its potential to cause skin, lung, and eye irritation, organ toxicity, and, primarily because of contamination by 1,4 dioxane, cancer.
The Dirty Dozen: Sodium Laureth Sulfate, 15 Toxic Trespassers, SKIP PRODUCTS MADE WITH SLES (AND SLS, TOO!), Campaign for Safe Costmetics: 1,4-DIOXANE, WHAT IS SODIUM LAURETH SULFATE: CHEMICAL FREE LIVING, A new formula for a mild body cleanser: sodium laureth sulphate supplemented with sodium laureth carboxylate and lauryl glucoside,
Sodium Lauryl Sulfate is recognised as a skin, eye, and respiratory tract irritant according to ICSC. It may cause allergic reactions and eye irritation as stated by the HSDB. Exposure may even result in eye burns, as per CAMEO. Depending on its form - which may range from a solid (90-98% purity), to a paste (30-41%), or an aqueous solution (28-50%) - it can significantly irritate skin and eyes, with adverse effects escalating with increased concentration. Despite these hazards, it is not a skin sensitizer according to CHEMINFO, while eChemPortal: ERMA and MSDSonline endorse its classification as an irritant.
Technical-grade Hexachlorocyclohexane (HCH) is a mixture of isomers used as an insecticide and in treatments for hair lice. Ingestion of HCH can lead to various health issues including hyperirritability, CNS excitations, respiratory failure and in some cases, leading to death. Long-term exposure can result in dermatitis, urticaria, leukemia, aplastic anemia, and lung cancer. Animal studies indicate that HCH is neurotoxic at acute doses and causes degenerative effects on chronic exposure. Ecotoxicity studies also reveal symptoms of poisoning in mallards and pheasants.
