Hello,

Sorry for the delay. Thank you so much for sharing your thoughts.
@ketchito I notice the changes when exposed to UV light, but the changes are drastic. I don’t notice them at 40°C though (maybe a slight change in color and a weaker smell but that’s it). I would like to improve the stability under UV light because the products are sold in a very sunny place and the products are most of the time exposed to light. Maybe it’s the water quality… I will try with the Tinogard, thanks for your help!

@PhilGeis thanks for the information, I have seen a lot of formulas using Na benzoate in shower gels. I also tried with phenoxyethanol
