  • SLES vs sodium c14-16 olefin sulfonate

    Posted by Abdullah on June 22, 2020 at 9:42 am

    If we replace SLES in Shampoo vs sodium c14-16 olefin sulfonate, how is the foam, detergency, mildness and salt carve compared to SLES? 

    I know a supplier for sodium c14-16 olefin sulfonate but MOQ is 25kg powder bug.

    Sodium laureth sulfate (SLES) is milder to skin & eyes than Sodium C14-16 a-olefin sulfonate (AOS), foams richer, builds slightly easier w/chelants, NaCl, amphoterics; and is generally less expensive. OAS does have better detergency, better hydrotrope than SLES and it builds with relative ease compared to other non-SLS anionics. It was mainly used in hand soaps until “sulfate-free” craze made it ubiquitous.

    @chemicalmatt thanks for advice. 
    I thought AOS would be milder. 

    What about Sodium lauryl methyl Isethionate and sodium cocoyl isethionate?

    I also saw charts (HET-CAM) showing that olefin sulfonate is significantly milder that SLES. It’s used as a primary surf in OGX shampoos which are milder than many on the market. I understand however that it could be due to other ingredients. Surfactants get milder when combined.
