Also for the thread, I’m going to change the preservative to Benzyl Alcohol (and) Benzoic Acid (and) Dehydroacetic Acid (and) Tocopherol. Will add citric acid if the pH is too high since this combo of preservatives works best at 3-6.

@Belassi
Thank you for your explanation! makes perfect sense and definitely a reason to think through using it. -
@czkld
Thank you so much, appreciate it! LMK if you have any preservative recco’s that isn’t the gluco+sb. -

@czkld
thank you! I will try HEC at .3%. I can’t add Niacinamide, my skin just doesn’t like it, but will definitely add the Citric Acid to lower the pH and then the Disodium EDTA as well.Question for you - should I just swap the preservative for a stronger one (reccos welcome) that way, I won’t need the BHT? trying to keep the ingredient list on the small side so i’m happy to cut what I need to in order to have a shorter list.

@LincsChemist
Thank you for your input! Do you recommend changing the preservative to something stronger if I am unable to do a challenge test? Copy on the Citric Acid though! -
@EVchem I haven’t tried the formula out yet but was hoping for 5 - 6. I also have Euxyl 9010 on hand here but I flush when I use phenoxyethanol so wanted to try a different preservative.
- Phenoxyethanol 90.0%
- Ethylhexylglycerin 10.0%
