MAGNESIUM LAURETH-8 SULFATE

Description

Magnesium Laureth-8 Sulfate is a synthetic surfactant commonly used in personal care and cosmetic products. This ingredient is derived from lauryl alcohol, which undergoes ethoxylation and sulfation processes before being neutralized with magnesium. As an anionic surfactant, it effectively reduces surface tension between water and oils, making it an excellent cleansing agent.

In skincare and haircare formulations, Magnesium Laureth-8 Sulfate functions primarily as a gentle foaming and cleansing agent. It produces a rich, stable lather that helps remove dirt, excess oils, and other impurities from the skin and hair. Compared to its sodium-based counterparts, the magnesium variant is often considered milder and less likely to cause irritation, making it suitable for sensitive skin types.

This ingredient also acts as an emulsifier, helping to blend oil and water-based components in product formulations. Its mild nature allows for effective cleansing without overly stripping the skin's natural oils. Magnesium Laureth-8 Sulfate is biodegradable and generally well-tolerated, though individuals with extremely sensitive skin may still experience mild irritation. It is often used in conjunction with other surfactants to create balanced, gentle cleansing systems in various personal care products.
