Sodium C14-16 Olefin Sulfonate (AOS | CAS 68439-57-6): A High-Performance Surfactant for Personal Care and Cleaning Formulations
Introduction
As the global personal care and detergent industries continue to evolve, manufacturers increasingly require surfactants that provide strong cleansing performance, rich foam stability, formulation flexibility, and cost efficiency. Among the widely used anionic surfactants in modern formulations, Sodium C14-16 Olefin Sulfonate (AOS | CAS 68439-57-6) has become a preferred ingredient due to its excellent detergency, foaming capability, and broad application compatibility.
AOS is extensively used in:
- personal care products
- household detergents
- industrial cleaning systems
- concentrated surfactant formulations
Its balance of performance and versatility makes it an important raw material for both consumer and industrial markets.
What Is Sodium C14-16 Olefin Sulfonate?
Product Name: Sodium C14-16 Olefin Sulfonate
Abbreviation: AOS
CAS Number: 68439-57-6
Chemical Class: Anionic surfactant
AOS is produced through the sulfonation and neutralization of alpha-olefins. It offers excellent surface activity and is well known for delivering:
- strong cleaning performance
- rich and stable foam
- good emulsification capability
- excellent hard water resistance
Compared with some traditional surfactants, AOS demonstrates strong compatibility in both cosmetic and detergent systems.
Main Product Specifications

💧 AOS 35% Liquid
A balanced liquid grade suitable for:
- shampoos
- body wash
- hand soap
- liquid detergents
This specification offers good performance with cost efficiency for daily-use formulations.
💧 AOS 38% Liquid
A higher active-content liquid grade designed for:
- enhanced foaming systems
- concentrated liquid formulations
- improved formulation efficiency
It provides stronger surfactant performance while maintaining excellent processing compatibility.
⚪ AOS 92% Powder
A high-active powder grade widely used in:
- concentrated detergents
- powder cleaning systems
- solid cleansers
- industrial cleaning applications
The powder form offers easier transportation, higher active matter, and flexible formulation design.
