Sodium Cocoyl Isethionate
Ingredient Info
Sodium cocoyl isethionate (SCI) is a gentle, plant-derived cleanser made from coconut oil. It removes dirt and oil from skin while being milder than many other cleansing ingredients, making it popular in gentle facial cleansers and beauty bars.
Benefits
- Effectively cleanses without stripping skin
- Gentler on skin barrier than stronger surfactants like sodium lauryl sulfate
- Well-tolerated by most skin types, including sensitive skin
- Biodegradable and derived from natural sources
Potential concerns
- Can cause mild irritation, redness, or dryness in sensitive individuals at higher concentrations
- May cause transient increases in water loss from skin with single exposure, though recovery is relatively quick
Science: Research confirms SCI is significantly milder than many alternative surfactants because its larger molecular structures are less likely to penetrate deep into skin layers. It has been safely used in skincare products for over 30 years, though individual sensitivity varies.
