  • Foaming handwash

    Posted by Mel55 on July 8, 2020 at 8:00 am

    Hi,
    I would like to make a handwash for use in a foaming bottle - just for myself, not for sale.  I am just looking for something that cleans hands but is not too drying. Could you please advise if I am on the right track with this formula? Should I add some emollients/humectants?

    SLeS 20% (70% active)
    Cocoamidopropyl betaine 10% (30% active)
    Liquid germal + 0.5%
    H2O 69.5%

    TIA.

    Oops sorry, didn’t mean to post this in the hair section!

    That looks perfectly reasonable, possibly slightly more SLES than strictly necessary. You might want to play around with the relative SLES:CAPB ratios - more CAPB gives denser foam, whereas more SLES gives lots of loose, open foam. 

    I wouldn’t bother adding humectants etc, there’s very little point in a rinse-off product

    I have made similar formulations as tests a few times and it was not satisfactory at all. Leaves hands very dry, so I would definitely add emolients and humectants. The more inexpensive commercial handwashes available here are a mixture of SLES/CAPB, Salt and Polyquat 7.

    I agree (Cafe33). For me, SLES has a really horrible ‘short flow’ (draggy, dry) feeling to it. Really crummy surfactant, so common for one reason only: It’s the cheapest.

    Thanks all, so what would be your preferred surfactant/s for an inexpensive handwash?

    I have no idea on the proportions of the ingredients but as a consumer with very dry skin, I really like the very simple Bio D hand-wash. I find most hand washes too drying but this one cleanses well without residue but doesn’t seem to sap my skin. It has a nice lather and I also have it in foaming pump dispensers. I like the fragrance free version.. it has no weird smell.

    https://biodegradable.biz/shop/hand-soaps/bio-d-sanitising-hand-wash-fragrance-free-500ml/

    The ingredients listed on the bottle are:

    Aqua, Sodium Laureth Sulphate, Cocamide DEA, Sodium Hydroxide, Citric Acid, Lactic Acid, Sodium Chloride


    I don’t know why the ingredients listed on the website are slightly different to the ingredients on the bottles…
