    Hey guys,

    A short version of the question: What happens if I add too much chelating agent into my formula? 

    A longer version of the question: After listening to last Q&A with Mark I was happy it was confirmed I should be always adding chelating agent into my formulas to help with preservation etc. (except for the formulas where not suitable).
    Most of the chelating agents are recommended at around 0.1%. 
    What would happened if I would add more? Let’s say 0.5%? Would it effect stability? Would it had reverse effect and instead of helping, it would harm my formula?

    Some agents…like sodium phytate are commonly used at that level….not so much because they think it is needed for chelation, but for the belief there are added skin benefits.

    I don’t necessarily agree with the following statement…but here is what the people SELLING it say:

    In addition to its chelating properties, Sodium Phytate has other skin benefits:

    • Moisturizes skin
    • Improves skin elasticity
    • Normalizes oily skin
    • May help reduce pore size
    • Helps lighten skin
    • May help improve the appearance  of cellulite

    The chemist will find it easier to answer your question…if you list the chelator you plan to use.  Then after you tell them that….they will say…depends on the balance of the formula.  ;)

    Gluconalactone is a chelator too. You can add much more than 0.1%.
