Sodium Lauroyl Sarcosinate
Ingredient Info
Sodium lauroyl sarcosinate is a gentle surfactant (cleaning agent) derived from coconut oil and amino acids. It's commonly used in facial cleansers to remove dirt and oil from skin while being milder than many traditional detergents.
Benefits
- Effective at cleansing without excessive harshness
- Derived from natural sources (coconut oil-based)
- Gentler alternative to sodium lauryl sulfate (SLS)
Potential concerns
- May alter skin's bacterial balance and reduce microbial diversity with regular use
- Can disrupt skin lipids (fats), particularly ceramides which support skin barrier health
- Rare cases of allergic contact dermatitis reported in sensitive individuals
Science: Recent research (2024) found that sodium lauroyl sarcosinate in facial cleansers reduced beneficial skin bacteria diversity and decreased protective ceramides while increasing certain lipids, suggesting potential long-term impacts on skin barrier health. It has a documented safety history, though allergic reactions are possible in sensitized individuals.
