thank you very much @Perry

I would be needing a preservative system to make a cream at pH 5- 5.5 the formulation would be

water: 65%
glycerin: 2%
olivem 1000 (cetearyl olivate, olive sorbitan) 5%
Jojoba oil 8%
Rosehip Oil 12%
Shea butter 1.5%
beeswax 1.5%
urea 1%
alpha tocopherol 0.05%
Euxyl pe 9010 1%

I would be missing a chelator like EDTA, I was thinking of adding a percentage of 0.2%

I also do not know if it would be necessary to add 0.2% citric acid and Myritol (capric triglyceride) 0.5%

Good afternoon ngarayeva001, thank you very much for answering, I am trying to use preservatives that do not have parabens, this is because in Argentina there are many people who have intolerance or allergy reactions to certain parabens, one of them is me, I know that parabens are much more safe and accessible, but wanted to see alternatives to them.

Good morning, thank you very much for accepting me in the forum. I am Pamela from Argentina, I studied Chemistry, recently I dedicated myself to the formulation of cosmetics.
What worries me the most is the issue of preservatives, my intention is NOT TO USE PARABENS so I consult it.
I am from Argentina and some supplies are not available here.
I was using Cosgard as the only preservative, to which I did not add any chelating agent (very bad).

In Argentina I recently bought Euxyl pe 9010 and I was thinking of using EDTA as a chelator and some antioxidant like citric acid.
I would be very grateful if you could help me to see the different possibilities of preservatives to ensure that the product is maintained over time.

Thank you very much. Best regards to all.
