1. What is Alpha Olefin Sulphonate (AOS)?

Alpha Olefin Sulphonate (AOS) is an anionic surfactant derived from alpha olefins. It is widely used in personal care and cleaning products due to its:
✔ High foaming ability (even in hard water)
✔ Gentle on skin (compared to harsher surfactants)
✔ Biodegradable & eco-friendly
✔ Stable across a wide pH range

AOS is available in two forms:

• Alpha olefin sulphonate liquid (ideal for shampoos & body washes)
• Alpha olefin sulphonate powder (used in detergent formulations)

2. What Are the Main Uses of Alpha Olefin Sulphonate in Cosmetics?

AOS is a popular AOS surfactant for personal care due to its mildness and performance. Some common applications include:

• Alpha olefin sulphonate for cosmetics (shampoos, face washes)
• Alpha olefin sulphonate in body wash (creates rich lather)
• Alpha olefin sulphonate shampoo base (gentle cleansing)
• AOS liquid surfactant (used in liquid soaps & bubble baths)

It’s also used in household products like AOS detergent base for dishwashing liquids and laundry detergents.

3. Is Alpha Olefin Sulphonate Safe for Skin?

Yes! AOS is considered safe for skin when used in proper concentrations. Unlike SLS (Sodium Lauryl Sulfate), which can be harsh, AOS surfactant is milder and less irritating.

Key safety points:
✔ Low irritation potential (suitable for sensitive skin)
✔ Readily biodegradable (eco-friendly)
✔ Compliant with cosmetic safety standards

For detailed safety information, always check the Alpha olefin sulphonate MSDS before formulation.

4. How is AOS Different from SLS and SLES?

Many people compare AOS vs SLS or AOS vs SLES when choosing surfactants. Here’s how they differ:

Feature	AOS	SLS	SLES
Gentleness	Mild	Harsh	Moderate
Foaming	Excellent in hard water	Good (but harsh)	Good (needs soft water)
Biodegradability	High	Moderate	Moderate
Irritation	Low	High	Medium

AOS is often preferred because it balances cleansing power with skin safety.

5. Can AOS Be Used in Baby Products?

Yes! Due to its mild nature, Alpha Olefin Sulphonate is suitable for baby shampoos and washes. However, always ensure proper dilution and safety testing before formulation.

6. What is the pH Range of Alpha Olefin Sulphonate?

AOS works well in a pH range of 5.5 to 7.5, making it ideal for skin-friendly formulations. Its stability across different pH levels makes it a reliable AOS surfactant for personal care.
