Sodium Laureth Sulfate
Ingredient Info
Sodium Laureth Sulfate (SLES) is a cleansing agent that helps remove oil and dirt from skin and hair. It's a mild surfactant commonly used in shampoos, body washes, and facial cleansers to create lather and improve product effectiveness.
Benefits
- Effective at removing oils and impurities
- Creates satisfying lather in cleansing products
- Milder than some alternative surfactants
Potential concerns
- Can be drying or irritating to sensitive skin with prolonged contact
- May cause contact dermatitis in individuals with sensitive skin
- Higher occupational exposure risk for hairdressers; consumer exposure generally considered acceptable
Science: Limited peer-reviewed data specifically addresses SLES safety in consumer skincare products. A systematic review of hair cosmetic ingredients noted that while current safety standards consider typical consumer exposure acceptable, the irritant potential of surfactants like SLES warrants attention in sensitive populations. Research confirms SLES is effective at cleansing, though individual sensitivity varies.
