Safety and consideration for sodium lauryl sulfate
Most studies of SLS are related to the consumption of pure SLS by animals or its use directly in their eyes. However, in ordinary cosmetics, this substance is not used in this concentration. However, there are no studies on the effects of long-term use of these products, so studies with higher purity of SLS are performed. in the view of the fact human body lacks enzymes capable of breaking down SLS, it accumulates over time. What is SLS? Sodium laryl sulfate or texapen (SLS) for short with the formula NaC12H25SO4 or sodium dodecyl sulfate SDS or the adjacent substance sodium lauryl sulfate or sodium lauryl sulfate (sodium lauryl ether sulfate) Anionic surfactants are synthetic cleaners with high power and more precisely as surfactants (surfactants or active ingredients). SLS is an emulsifying, blowing, dissolving, and foaming chemical compound used in the detergent, alarm, or food industries, and its active ingredients are…
Physical and chemical properties of SLS
The critical micelle concentration (CMC) of sodium lauryl sulfate in pure water at 25 ° C is 8.2 mm and the accumulation number at this concentration is usually about 62.The percentage of micelle ionization (α) is about 0.3 (or 30%). It is used in a wide range of concentrations. According to a 2015 study, 0.01% to 50% is used in cosmetics and 1% to 30% in cleaning products. Applications – SLS SLS has many applications, mainly in various detergents. It is a very effective surfactant and is used in any work that requires the removal of greasy and stabilized stains; For instant it is found in high concentrations in industrial products, including car engine cleaners, car floor cleaners, and car wash soaps. At lower concentrations, it is used in toothpaste, shampoo, beard paste. The reason for its use in these fields is its ability to create foam, its surfactant properties…
