SODIUM MYRISTYL SULFATE
Description
Sodium Myristyl Sulfate is a synthetic surfactant commonly used in personal care products and cosmetics. This anionic compound is derived from myristic acid, a naturally occurring fatty acid found in coconut oil and other plant sources. Its primary function is as a cleansing agent, effectively removing dirt, oil, and other impurities from the skin and hair.
In skincare formulations, Sodium Myristyl Sulfate creates a rich, foaming lather that aids in the cleansing process. It has a moderate cleansing ability, making it gentler than some other sulfates like Sodium Lauryl Sulfate. This characteristic makes it suitable for individuals with normal to slightly sensitive skin types.
The ingredient also acts as an emulsifier, helping to blend oil and water-based components in formulations. Its ability to reduce surface tension allows for better product spreadability and penetration into the skin. While generally well-tolerated, some individuals may experience mild irritation or dryness, particularly with prolonged use or in high concentrations.
Sodium Myristyl Sulfate is biodegradable and considered safe for use in cosmetics when formulated properly. However, as with any surfactant, it may potentially disrupt the skin's natural barrier if used excessively or in harsh formulations.
