What Is Cocamidopropyl Betaine (CAB35)?
Cocamidopropyl Betaine, commonly abbreviated as CAB35, is an amphoteric surfactant derived from natural coconut oil. “Amphoteric” means it can exhibit different electrical charge characteristics depending on the environment. This unique behavior gives CAB35 exceptional versatility in personal care formulations.
How It Works at Different pH Levels
| pH Environment | Behavior |
|---|---|
| Neutral (pH ~5–7) | Mild, balanced cleansing |
| Acidic (pH <5) | Slightly cationic (positive charge) – provides conditioning and anti-static effects |
This pH-responsive nature is rare among surfactants and unlocks multiple benefits in one ingredient.
The Five Key Functions of CAB35
1. Gentle Cleaning
CAB35 effectively removes dirt, oil, and impurities without stripping the skin’s natural moisture barrier. It is considered a mild cleansing agent, suitable for sensitive skin, baby products, and facial cleansers.
2. Rich & Stable Foam
It is an excellent foam booster. CAB35 produces dense, creamy, and stable foam even in the presence of oils or sebum – critical for shampoos, shower gels, and shaving creams.
3. Thickening Synergy
When combined with primary anionic surfactants (e.g., SLES, SLS), CAB35 increases viscosity. This reduces the need for additional thickening polymers, simplifying formulations and improving sensory feel.
4. Conditioning & Softness
Thanks to its cationic behavior in acidic pH (typical of rinse-off products), CAB35 provides mild conditioning. It leaves hair feeling soft, manageable, and less static, while skin feels smooth after washing.
5. Irritation Reduction
CAB35 is known to lower the irritation potential of stronger primary surfactants. It improves the overall mildness of the formula, making it ideal for everyday use products.
