Product description

Cocamidopropyl Betaine is an amphoteric surfactant (betaine) derived from fatty acids of coconut oil. It is produced by synthesis from coconut-based fatty raw materials – first, an amidoamine is prepared from coconut fatty acid and aminopropyl, then it is “betainized” (quaternization) into a stable amphoteric structure.
In practice, it acts as a secondary surfactant that makes the cleansing profile milder, supports the formation of a creamy and stable foam and improves the behaviour of surfactant blends (including thickening and reducing the irritancy of stronger anionic surfactants). It is often used in modern “sulfate-free” formulations as well as in combination with sulfates, where it increases comfort and foam performance.

Key benefits

• Milder cleansing – reduces irritation and the “degreasing” feel in surfactant systems.
• Creamy and stable foam – improves both foam volume and foam feel.
• Synergy in blends – works very well with anionic and non-ionic surfactants (glucosides, sarcosinates, sulfosuccinates).
• Better processability – helps with thickening and improves viscosity stability in many formulations.
• Versatile use – shampoos, shower gels, facial cleansing gels, liquid soaps.

Suitable for products such as

• Shampoos (liquid and gel) – milder profile and better foam.
• Shower gels and bath foams – creamier, more stable foam.
• Facial cleansing gels and foams (rinse-off) – milder profile in combination with other surfactants.
• Liquid soaps and hand wash gels – better foaming and comfort after washing.
• Intimate hygiene (rinse-off) – in mild surfactant blends and with appropriately adjusted pH.

Use in formulation

• Soluble in: water (commonly supplied as an aqueous solution).
• Miscible with: anionic, non-ionic and other amphoteric surfactants; often combined with Lauryl Glucoside, Sodium Lauroyl Sarcosinate or Sodium Cocoamphoacetate for a milder and more foaming system.
• Compatible with: humectants (glycerin, propanediol), chelating agents and common thickeners for surfactant systems; when thickening with salt, it is recommended to dose in small steps.
• Dosage (indicative): typically as a secondary surfactant in shampoos and shower gels.
• Technological tip: add to the water phase or to the finished surfactant base under gentle stirring to minimise air entrainment; adjust pH only after homogenisation and after adding fragrance/preservative.

Safety and storage

• Intended for cosmetic use; avoid contact with eyes and mucous membranes.
• When working with surfactants, use appropriate protective equipment; avoid aerosol formation and excessive foaming during mixing.
• Store in a tightly closed container, in a dry place, away from direct sunlight and sources of heat.
• For products intended for sensitive skin, minimise fragrance and always test the final formulation (pH, tolerance, stability).
