  • Looking for a chemist in the USA to test a cream for suspicious ingredients

    Posted by Anonymous on May 10, 2016 at 12:39 am

    Hello,

    I am looking for a chemist based in the USA to test a cream that I want to purchase. The cream according to many people is very effective. I was wondering if the ingredients only were the reasons why the cream is effective. The product is manufactured in a country where there is no regulations. Therefore companies can put whatever they want on their ingredient list. Maybe the cream contains things like mercury or steroids which can make a brightening cream more effective. So I am looking for someone who can tell me if the cream contains anything like that before I use it. If you can do that or know someone who can please let me know. I will send the product to the chemist who has to be leaving in the US.

    Thanks in advance,

    Oumie

    you’ll need to consult an analytical lab, this type of work is not done by cosmetic chemists

    just out of interest, why would they have to be in the US?

    You need a lab for this, definitely. It requires expensive analytical equipment that would be far, far out of reach for an individual chemist to afford.

    I’d suggest Avomeen, if you have to use an American lab. http://www.avomeen.com/

    @Bill_Toge thank you! I havr to send the cream to the lab. It is easier if it is in the US or Canada
    @Bobzchemist I did not know it required expensive equipments. Thank you for letting me know. I will check that out!

    Looking for unknown compounds in an unknown matrix is a very expensive and complicated story. If you just give a sample to a lab you won’t get an answer unless you give them a clue what they have to look for. A task like that can in theory keep a research team busy for decades (even in a top modern analytical lab).

    Skin bleaching is such a dangerous area and ethically too, I personally want to be nowhere near it.

    Hello, @Belassi It is not a bleaching product. Even though it is not a bleaching cream, I still want to make sure it does not contain anything harmful. @David I want to make sure it does not contain mercury or steroids.

    a quick and easy qualitative test for mercury would be to disperse some of your cream in hot water and add diphenylcarbazone

    if the water turns dark blue/violet, there’s mercury in the cream

    For the steroids a GC-MS would come handy.
