Hazards of sodium dodecyl sulfate (SLS)

Sodium Lauryl Sulfate (twelve sodium sulfate) is a common ingredient of personal care products It is an additive for foaming products According to the skin deep cosmetics safety database of environmental protection organization, SLS is a kind of moderate harmful substance related to cancer, neurotoxicity, organ toxicity, skin allergy and endocrine disorders Sodium dodecyl sulfate is defined as an emulsifier and foaming agent often used in cosmetics and industrial cleaning agents SLS can be found in most body lotions, soaps, shampoos, toothpastes and washing powders Although sodium dodecyl sulfate is extracted from coconut oil, it will be polluted by toxic by-products during processing The chemicals related to sodium dodecyl sulfate also include sodium dodecyl ether sulfate and ammonium lauryl sulfate, both of which have similar foaming ability and are harmful to health Toxic cosmetic ingredient review reports that SLS, sles and ALS will be irritant when the concentration is more than 2%, and it is recommended that the concentration of cosmetics should not be more than 1% Undiluted sodium dodecyl sulfate can cause skin and eye irritation, as well as adverse reactions such as nausea, vomiting and diarrhea Sodium dodecyl sulfate and sodium dodecyl ether sulfate (sles) are often polluted by 1,4 dioxane, which is a by-product of the processing In addition to being a potential carcinogen, 1,4 dioxane also has negative effects on the kidney, liver and central nervous system It should be noted that most studies on sodium dodecyl sulfate are based on animals, using test methods such as feeding or application for eyes Normal use of cosmetics usually does not present this exposure There is a lack of research on the long-term cumulative effect of SLS exposure Because the body lacks the enzymes that break down certain chemicals, they build up gradually Therefore, consumer protection organizations advise people to use products with SLS carefully If you are concerned about the potential impact of sodium dodecyl sulfate accumulation, look for shampoos, toothpastes, and other personal care products that do not contain SLS Sodium coco sulfate is also a kind of coconut derivative, which has less stimulation than SLS and sled and can replace them In addition, you can also look for shampoo made of essential oil, or shampoo with baking soda.
