    Hey guys, I want to thank you all for your help earlier. I applied your suggestions and I still have some issues that I need your help with.

    Is germall plus an effective preservative in a lotion containing sepiwhite. This is the second time I’ve tried it but each time after a few days the smell starts to change. I’ve also altered the recipe to see what’s wrong.

    Water 65.600

    EDTA 0.200
    Glycerin 3.000
    Guar Gum 0.500
    Stearic Acid 2.000
    Emulsifying wax 4.000
    Shea butter 2.000
    Oil 8.000
    Beeswax 2.000
    Germall plus 0.500
    Tocopherol 0.500
    Rosemary essential oil 0.500
    Lavender fragrance oil 0.200
    Niacinamide 4.000
    Licorice 2.000
    Zinc oxide 3.000
    Sepiwhite 2.000
    These are in percentages

    Yes it is effective.

    What is the pH? 

    At what temperature do you cook Germall plus? It should not be heated above o think 50°c.
