    I suggest Dissolvine GL (Tetrasodium Glutamate Diacetate).

    You can also try Tsuno Rice Chemical’s Phytic Acid (IP6).

    The suggestion of Phytic Acid is very interesting to me. This is because most nuts and legumes are high in phytic acid and was just reading up on them recently that they might be causative to acne. I never thought they were just doing a good job as chelating agents.

    I love this forum!

    Thanks for all the suggestions.

    Unfortunately, many “natural” chelators are not very effective.  You can see more info on this in this discussion forum: https://www.facebook.com/groups/makingskincare/ :

    One thing is for sure, with all the concerns about EDTA, I wouldn’t want it to touch my body nor give it to someone else.

    What? Where did you get that? EWG? Skin Deep? Nothing wrong with EDTA.

    Yes EWG, Skin Deep etc etc etc, there’s a LOT of scaremongering around.

    If you have concerns braveheart you can look it up: http://www.cir-safety.org which provides unbiased, scientific, expert advice on cosmetic ingredients and, the European Scientific Committee for Consumer Safety is a politically and commercially impartial panel of doctors and toxicologists, whose job it is to review safety data for materials - http://ec.europa.eu/health/scientific_committees/consumer_safety/opinions/index_en.htm

    main reason not to use EDTA is that it is not easily biodegradable

    It was the fact that EDTA is not easily biodegradable that put me off, because I thought if that is the case my body systems may find it difficult to handle, why put it on my body when there are substitutes? I may be wrong, but that is my line of thought. Then, by the time you read around the Internet and find so many users complaining about an ingredient, then, to an extent, it throws the science out of the window.

    I appreciate the contrary opinions about my bias towards EDTA. At the end of the day, it is not experts whom you are marketing to, but the public that may be biased already. It is easy to say, because of the good science behind it, I will go ahead and use it, well, I am not a multi-billion-dollar company who can spend enough to change public perception. So, while trying to birth a publicly acceptable product, I must be aware of public perception of each ingredient used.

    I second Dissolvine GL (Tetrasodium Glutamate Diacetate).  Readily biodegradable and when combined with citric acid really boosts the performance of preservatives.

    Thanks again, @MarkBroussard. Ever since it was mentioned by @Ozgirl, I’ve scoured the Internet for where to get it in the UK, anyone with the knowledge of Dissolvine GL’s availability in the UK?

    Or Natrlquest E30’s suppliers in the UK?

    @Kirk, is that phytic acid (IP6) the same as Inositol, which I think is a biodegradable ingredient?

    Not sure about availability in the UK. We get ours (in Australia) through IMCD group who is a distributor for Akzo Nobel. IMCD had offices in the UK (http://www.imcdgroup.com/worldwide/united-kingdom) so you could try contacting them to see if they distribute this product in the UK. I am not sure how much you are looking to buy but if they are the UK distributor but you only want small (personal use) amounts they might be able to suggest smaller suppliers/resellers.

    Hope this helps

    You can try Natrlquest E30 from Innospec. I have also used the DissolvineGL.  It works well.

    @braveheart Inositol is the poly-alcohol form of cyclohexane, with six -OH groups around the cyclohexane core. On the other hand, phytic acid also has the cyclohexane core like inositol, but instead of -OH groups attached to it, dihydrogen phosphate (-H2PO4) groups are attached to it. These dihydrogen phosphate groups gives phytic acid its chelating property.And yes, inositol and phytic acid are both biodegradable.

    @Kirk, thanks for the insight!

    At this rate, I will soon earn a bachelors degree in cosmetic science, just by learning from all the tips, advice and insight here.
    Experts are so helpful on this forum. Thanks so much!
