    Putting eucalyptus oil in your product is killing your foam.

    First off, it's real confusing to mix weights and volumes in a formula. We prefer percentages. Roughly, your formula is: 

    Water 82.67%
    Sodium Laureth Sulfate 6.89%
    Sodium Chloride 6.89%
    glycerin 1.38%
    propylene Glycol 1.38%
    Pearlizer 0.69%
    preservative 0.03%
    Eucalyptus oil 0.07%

    The first thing that jumps out at me is that you don't have enough preservative, unless you are using something truly nasty that shouldn't be on skin anyway.

    There's not enough eucalyptus oil that taking it out will improve your foam much.

    Sorry, but 6.89% SLS is simply not enough surfactant, particularly since you are only using one.

  • If you tell us the purpose of this cleaner, it would make it easier to help you. For example, if this is a shampoo, you probably want somewhere between 25-40% surfactants. Usually a blend is preferred over a single surfactant, both for performance and to improve mildness.

    6.89% salt is too high too.
  • Thank you very much for the response 

    the purpose of my cleaner is to release stress and also to enjoy bathing

    At Perry what percentage of salt and sle do i need to make my soap foam 
    thank you 
  • Please can you throw more light on the sls and salt, what amount needed to foam well

    If you are not capable of determining this experimentally, you should not be using chemicals to make anything. For your own safety, please buy pre-made products.

    To determine salt levels see our post on the subject.  https://chemistscorner.com/salt-curve-analysis-how-to-control-cleansing-cosmetics/

    But salt will not have a large impact on foam.  It's just that if you use too much you don't get viscosity control plus it can be stinging to eyes.
  • MarkBroussardMarkBroussard Member, Professional Chemist
    Generally, your salt curve will peak at about 2.5% to 3% as a viscosity enhancer.  Thereafter, additional salt will actually thin your product.

    Increase your SLS to the 30% to 40% range.

    Add the salt as the last step in your formulation.  Try using 2%, 2.5% and 3.0% to see the effect on viscosity.

  • What preservative are you using at 0.03% ?

    Also instead of just using SLS try maybe Disodium Lauryl Sulfosuccinate, Lauryl Glucoside & Cocamidopropyl Betain blend.

    Ditch the Salt!
  • Come on Bob.. You used to be nice.
    I think that this site isn't only for experimented cosmetic chemist.
    BTW the pearlizer could be killing the foam too. But the main problem is that you are using only 1 surfactant in low percent.

    Sorry, he caught me at a bad moment. I'm getting tired of people who want me to do all their work for them and/or do not have the patience to do any research on their own.

  • Thank you everyone 
    your response has been useful.
    as advice by Bob i will start experimenting to get the best formula 
     
  • I think the concentration of sodium laureth sulfate may be even lower than stated, because where do you get it as a dry material?  It's probably a solution which may be 30%-70% actives.
