  • Reclaiming a too thin handsoap

    Posted by Anonymous on October 13, 2016 at 6:22 pm

    We made a hand soap in the plant and the viscosity was low. We use salt to thicken the soap. We think the operator may have overshot the salt but we’re not certain. Is it possible to increase the viscosity of the thin soap?

    Only two ways I can think of. Use a thickener - but then you’ll have a different product.
    Or add more soap that has NO added salt, until you recover it.

    If you’ve overshot the salt curve then @Belassi suggestion to add some soap that has no added salt is your best bet.

    Calculate total batch weight. 

    with a small amount, adjust in the lab with primary surfactant until you have rebounded from the salt curve.  then just do the math

    sx wt + ing wt = total wt

    ing wt / total wt = ing conc

    ing conc * batch wt = how much to fix your stuff.

    Agree with chickenskin add more primary surfactant. The other option and it sounds crazy but it sometimes works depending on far over the salt curve you have gone but try adding water. Don’t forget always do a lab trial first.
