  • Anyone have experience using liquid soap for a scrub?

    Posted by RKB on July 9, 2023 at 3:29 pm

    I’ve never done this before, but I see it recommended from popular DIY product suppliers all the time. Is the liquid soap (recommendations are often to use liquid castile and also add some extra seed oil or extracts) enough to actually keep these types of scrubs stable?

    Curious minds. Thanks!

    What type of “scrub” are you asking about?

      I’ve seen it for salt and sugar scrubs - sorry, I forgot to clarify that.

    well if you use it right away it will Propoly work. if you add grain salt or Suger to a normal Liquid Soap Formulation it will dissolve and destabilize your formulation over a longer time.

    So if you are adding the scrub particles to the soap and use it right after it will work but not in the long run you would need to adapt the formulation so that the srub particles will not dissolve and not separate from the product.

    For two decades my company formulated and manufactured liquid castile made by saponifying extra virgin olive oil. We produced wholesale quantities of products that were exported globally. And in twenty years never had any issues.

    I should also mention that we were not hobbyists / DIY and were GMP Certified.

    But care needs to be taken with selecting the “scrub” component of the formulation.

    Micro contamination is a cryptic risk - esp. with addition of salt and sugar.

    Note recent US recall - Castile Soap Towelette - Product is contaminated with Nesterenkonia lacusekhoensis..
