Preparation of 35% sodium α-olefin sulfonate AOS

Sodium Alpha Olefin Sulfonate (AOS) is a surfactant commonly used in the production of various cleaning and personal care products. It is an anionic surfactant derived from the reaction of alpha olefins with sulfur trioxide gas, followed by neutralization with sodium hydroxide.

AOS is available in different concentrations, and AOS 35% refers to a solution of Sodium Alpha Olefin Sulfonate where the active ingredient concentration is 35%. The remaining portion of the solution typically consists of water and other additives.

Some key properties and benefits of AOS 35% include:

1. Surfactant: AOS acts as a surfactant, meaning it reduces the surface tension between liquids and enhances the wetting, spreading, and foaming properties of products.

2. Good detergency: AOS exhibits excellent detergency, making it suitable for use in various cleaning formulations, such as dishwashing liquids, laundry detergents, and industrial cleaners.

3. Mildness: AOS is considered relatively mild compared to some other surfactants, making it suitable for use in personal care products like shampoos, body washes, and facial cleansers.

4. Compatibility: AOS is compatible with a wide range of other surfactants and additives, allowing for formulation flexibility and synergy with other ingredients.

5. Stability: AOS is stable under different pH conditions and in the presence of electrolytes, making it suitable for use in various formulations.

6. Foaming properties: AOS produces rich, stable foam, making it desirable in applications where foam generation is desired, such as in shampoos, bubble baths, and cleansing products.
