    Good morning @MarkBroussard I am recently dabbling in cosmetic formulation.
    What worries me the most is the issue of preservatives, my intention is NOT TO USE PARABENS is for this reason that I consult.
    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.
    
    I read in some forum discussions that you suggested to a person to use the following ratio of chelator, natural preservative and antioxidant,
    Euxyl pe9010 1%
    EDTA 0.2%
    Capric Triglycerid 0.5%
    Citric Acid 0.2%
    
    I would be grateful if you could guide me in this combination to ensure a good conservation of the product.
    
    If this combination is feasible, approximately how long would it keep a cream that has 65% water in its formulation.
    
    Thank you very much best regards
