SODIUM LANETH SULFATE

Description

Sodium Laneth Sulfate is a synthetic surfactant commonly used in personal care and cosmetic products. This versatile ingredient functions primarily as a cleansing and foaming agent, making it a popular choice for shampoos, body washes, and facial cleansers. Derived from ethoxylated lanolin alcohol and sulfuric acid, it offers effective cleansing properties while being gentler on the skin compared to some other sulfates.

The compound works by lowering the surface tension of water, allowing it to mix with oils and dirt on the skin or hair, which can then be rinsed away easily. Its foaming action contributes to the rich lather consumers often associate with effective cleansing. Sodium Laneth Sulfate is typically well-tolerated by most skin types, though individuals with very sensitive skin may experience mild irritation.

In formulations, this ingredient is often used in concentrations ranging from 1% to 5%, depending on the product type and desired effect. It is compatible with a wide range of other cosmetic ingredients, enhancing its versatility in product development. While effective, formulators should be aware that some consumers may prefer sulfate-free options due to growing market trends and personal preferences.
