Lip Gloss preservative
Thank you so much for this wonderful forum and experts who guide so well.
Making lip glosses and my base ingredients are:
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?
