    hi all

    Thank you so much for this wonderful forum and experts who guide so well.

    Making lip glosses and my base ingredients are: 

    castor oil
    capric Triglyceride
    candelila wax
    glycrin
    TKB cap-2 preservative

    what i do i melt the oils and wax then remove from heat, as soon as it cool down at room temperature i add glycrin as i am following some recepi. 

    it needs a broad spectrum preservative as we add glycrin in the base.

    2 questions: is tkb cap-2 is ok with this recepi?

     if yes should i add preservative according to the glycrin quantity by weight 0.8%- 1% (recommended by the supplier)

    or should i add preservative according to the whole weight as i make almost 150 grams of base,so preservative 1% (1.5 grams)? or according to the glycrin, which is 8 grams (0.8 grams preservative?

    The way I understand usage rates, is that your usage rate should be based on total weight of base.  If your base is 150 grams, TKB cap-2 should be 1.2 - 1.5 grams.  Personally, I don’t like TKB cap-2 because even at the lowest usage rate my lips get numb.  I found another preservative that I will be trying soon.
