Shampoo surfactant problem

Ammonium lauryl sulphate (ALS)
Cocomidopropyl betaine (CAPB)
Sodium lauroyl sarcosinate

Is their any way to get this stable.... <ALS need ph below 6,5 and Sodium lauroyl sarcosinate need above 6. Seem to be a small window, will this make a problem ?


Thanks

    I advise you not to try this, if it's true that the third surfactant needs a pH > 6. You will get the ALS breaking down and your product will smell of ammonia. Use another surfactant such as sodium cocoamphoacetate. pH max 5.5 for ALS to stay stable.

    so i need a very effictive surfactant, but a also want a high  pH in the product
    ph 5,5 is to low

  • AOS and CAPB should work.

    Sodium coco-sulfate (SCS)
    Sodium C14-16 olefin sulfonate (AOS)
     
    Sodium polystyrene sulfonate
     

    is the only i found work in this context

    Please inlight me 

  • I have not worked with ALS and can't comment on it, but Sodium Lauroyl Sarcosinate is a great surfactant and there is absolutely no need for it to be above 6. A useful chart:  https://www.instagram.com/p/B-cByGBHHiw/
    Olefin sulfonate is a great surfactant too, but sarcosinate is milder. Olefin Sulfonate lathers better.
