Formulation Notes – Cocamidopropyl Betaine Usage Rate and Guide:

  • PH Range: 5 to 6
  • Amphoteric surfactant
  • ASM (Active Surfactant Matter): 30% to 32% ASM content
  • Cocamidopropyl Betaine doesn’t lather well when used alone/ on its own. Therefore, it’s commonly used in combination with other surfactants
  • Is used as a secondary/ co-surfactant during formulation of cleansing products. It supports other surfactants to help make the entire surfactant blend milder, stabilize the lathering and improve flash foam
  • It is used to support other surfactants – helps improve lathering and thickness of the formulation/ final product
  • Helps thicken some surfactant blends due to its Sodium Chloride content

Cocamidopropyl Betaine vs Coco Betaine

Cocamidopropyl Betaine (CAPB) is not the same thing as Coco Betaine. They are completely different ingredients, although some people refer to Cocamidopropyl Betaine as Coco Betaine. They just have similar names. According to experts at ChemistsCorner, ‘Coco Betaine’ is Cocamidopropyl Betaine’ minus the “-amidopropyl” part of the molecule.
