  • Hand Sanitizer formulation and its effect on calirty of the product.

    Hi,
    I have tried to make Hand sanitizer formulation listed below
    Formulation 1
    Ethanol:           75%(99% purity)
    Water distilled: 20.9%
    Carbopol 940: 0.5%
    TEA:                0.1%
    Glycerin           3%

    Mixing order: Water, Carbopol, ethanol, TEA. 
    The result was carbomer just formed a cloudy gelly lump in the ethanol and as i tried to stir it vigorously most of it is evaporated.

    I would love to hear some insights on the above-mentioned issue. 

    Formulation 2
    Just changed the ethanol to IPA (99%), mixing procedure is the same and it worked but the product was not so clear in the end. It was a bit clumsy and air bubbles were present.

    May I know how I can get the crystal clear sanitizer similar to the purell brand? Is something wrong with the formulation or mixing?

    940 will not give the grade of gel you want. And TEA won’t work much above 63% anyway. This sanitiser thing is really annoying because of the supply shortages it has created.
