SLES and CAPB Blend — Shampoo Surfactant Base
What is SLES and CAPB Blend — Shampoo Surfactant Base?
The SLES and CAPB blend is the most widely used shampoo surfactant system globally. Sodium laureth sulfate (SLES) provides primary detergency and rich foam; cocamidopropyl betaine (CAPB) acts as an amphoteric co-surfactant that improves mildness, boosts foam density, and builds viscosity when salt-adjusted.

What is SLES and CAPB Blend — Shampoo Surfactant Base used for?
Extend the base with cocamide MEA for enhanced viscosity, lauryl glucoside for mildness, or explore sulfate-free syndet systems. See all personal care surfactant blends. Venus Ethoxyethers manufactures and supplies in India; request a quote for your requirements.
The SLES and CAPB blend is the most widely used shampoo surfactant system globally. Sodium laureth sulfate (SLES) provides primary detergency and rich foam; cocamidopropyl betaine (CAPB) acts as an amphoteric co-surfactant that improves mildness, boosts foam density, and builds viscosity when salt-adjusted. Venus Ethoxyethers supports formulators sourcing anionic surfactants and amphoteric betaines for this chassis.
Typical SLES + CAPB shampoo chassis
| Ingredient | INCI | Typical level (% active) | Function |
|---|---|---|---|
| Sodium laureth sulfate | Sodium Laureth Sulfate | 10–14% | Primary anionic cleanser, foam |
| Cocamidopropyl betaine | Cocamidopropyl Betaine | 3–6% | Co-surfactant, mildness, viscosity |
| Sodium chloride | Sodium Chloride | 0.3–1.5% | Viscosity adjustment (salt curve) |
| Citric acid | Citric Acid | q.s. | pH 5.0–5.5 |
Why formulators choose SLES + CAPB
- Proven performance — strong grease removal and consumer-accepted foam profile
- Mildness boost — CAPB reduces irritation versus SLES-only systems
- Viscosity control — salt curve with betaine enables target rheology without heavy thickeners
- Cost efficiency — competitive active cost for mass-market shampoos and body washes
