Advantages and disadvantages of sodium lauryl sulfate
benefits
High efficiency in foam production: One of the main advantages of SLS is its high ability to produce foam, which increases the efficiency of detergent and hygiene products.
Reasonable price: Sodium lauryl sulfate has a reasonable price compared to many other surfactants, which makes it an economical option for manufacturers.
Disadvantages
Skin and eye irritation: Long-term use of products containing SLS can cause skin and eye irritation. This ingredient may cause dry and itchy skin, especially in people with sensitive skin.Environmental effects: Sodium lauryl sulfate is difficult to break down in the environment and can be harmful to aquatic organisms. This has raised concerns about the widespread use of this substance.
