Betaine (Cocamidopropyl Betaine or Trimethylglycine) is an amphoteric surfactant and skin-conditioning agent with a 5% solution pH of 4.0–6.0. In personal care formulations, Betaine serves as a secondary mild surfactant and foam booster that enhances the mildness, conditioning performance, and skin feel of primary surfactant systems. It reduces the eye and skin irritation potential of stronger surfactants (such as SLES), making it a key ingredient in baby care, sensitive skin, and conditioning cleansing formulations.
Applications:
- Shampoos (secondary mild surfactant, foam booster, conditioning agent for hair cleansers)
- Body Wash (mildness enhancer, skin-conditioning co-surfactant)
- Baby Care (ultra-mild co-surfactant for baby shampoos and washes — tear-free formulations)
- Facial Cleansers (gentle conditioning cleanser for sensitive skin formulations)
Key Features & Benefits:
- pH 4.0–6.0 (5% solution) – compatible amphoteric surfactant
- Reduces irritation potential of primary surfactant systems
- Excellent foam boosting and stabilising properties
- Skin-conditioning – leaves skin feeling soft and smooth
- Essential in baby, sensitive, and conditioning cleansing formulations
