Sodium C14-16 Olefin Sulfonate (AOS-35)

  • INCI Name:       Sodium C14-16 Olefin Sulfonate
  • Chemical Name: Sulfonic acids, C14-16-alkane hydroxy and C14-16-alkene, sodium salts
  • CAS No:             68439-57-6

Sodium C14-16 Olefin Sulfonate is an anionic surfactant, referred to as AOS. It has excellent detergency, foaming power, emulsifying power and other properties; it is very soluble in water and has strong calcium soap dispersing power and hard water resistance; it has good biodegradability, mild to skin; good compounding performance; easy to rinse.

AOS is as mild as SLES, therefore, AOS has a wide range of uses in personal care products. It is extremely stable under acidic conditions. Normal human skin is weakly acidic (pH is about 5.5) and is suitable for using AOS as a component of personal cleaning products. The shampoo with AOS as the main active component is better than that with K12. It is reported that the foam released by AOS was full of cream and felt like soap when washed. Therefore, AOS can be used in personal care products such as bath fluids, hand sanitizer and cleansing milk.
