Essential Oil % limit in leave on formulation
A few weeks ago I finished a natural deodorant stick deo (wax based) it works well and now I want to make a sodium stearate +glycerin gel stick deo ( I have no access to zemea and want to keep it natural)
1) on my wax stick I used safe synthetic fragances (safer choice), on my new formulation I want to use essential oils, im aware they contain sensitizers and toxic compounds. Is there a suggested % or limit to be used in a deo application? (juniper, lavender, citric,etc)
2) I have two antimicrobial blends to choose from a supplier: phenethyl alcohol+caprylyl glycol OR pentylene glycol+caprylyl glycol +ethylhexylglycerin. Which do you think would work and last longer? Im leaning towards the 2nd because it contains 3 compounds and I guess more antimicrobial action? also better solubility…
