AOS 40
High foam cleansing surfactant for rinse off formulas. Strong performance, good clarity potential, easy to blend.
AOS 40 is an anionic surfactant commonly used as a primary or secondary cleanser base in body washes, hand washes, facial cleansers, and shampoos.
It delivers rich foam and strong detergency, and it pairs well with amphoteric surfactants to improve mildness and reduce irritation potential.
It can be used in clear systems depending on your blend, salt curve, and fragrance load.
FEATURES
- High foam output – builds dense lather suitable for body wash and cleansing gels.
- Strong detergency – effective cleansing for rinse off systems.
- Blend friendly – combines well with CAPB and nonionics to balance feel and reduce harshness.
- Good structure potential – viscosity can be tuned with salt and polymer systems depending on your surfactant blend.
BEST FOR
- Body wash
- Hand wash
- Facial cleanser gels
- Shampoo blends
FORMULATION GUIDELINES
| INCI | Sodium C14-16 Olefin Sulfonate (typical). |
|---|---|
| Chemical Class | Anionic surfactant (AOS) |
| Solubility | Water soluble |
| Use Rate | Typical: 3–15% as supplied in rinse-off systems. Can go higher in body wash bases depending on mildness targets. |
| pH Stability | Best used in mildly acidic to neutral rinse-off systems. Typical finished product pH target: 5.0–6.5 for consumer cleansers. |
| Temperature Tolerance | Typical: stable under normal processing. Avoid prolonged high heat. If heating is needed, keep practical processing below 60°C and avoid holding time. Confirm on supplier TDS for your grade. |
| ASM (Active Matter) | Typical: 40% |
| Pro Tip | For a smoother, less harsh cleanser, pair AOS 40 with an amphoteric (CAPB) and a mild nonionic. Build viscosity gradually, because the salt curve depends on the blend. Add salt slowly in small increments while mixing, pausing between additions, and stop once the viscosity peaks. If clarity drops, reduce salt or adjust the surfactant ratio. |
| Appearance | Clear to slightly hazy liquid |
| Stability Notes | Viscosity and clarity depend on electrolyte level, fragrance load, and surfactant ratio. Test with your preservative and fragrance early. Avoid over-salting. |
| Storage | Keep sealed, cool and dry. Protect from extreme temperatures. Mix well before use if separation occurs. |
Always verify exact limits on the supplier TDS/CoA for your batch, then confirm with stability testing.
