    *NEW* Legacy Pro "Mic-X" is it the real stuff?

    Our good friends in California have a new product Called "legacy Pro Mic-X Developer" http://www.freestylephoto.biz/749710...-Make-1-Gallon

    The MSDS has the Logo of Photo Systems in MI, the folks that used to make Unicolor products.

    The claim is that this is a clone of Microdol X which was recently "cut back" by the Yellow package guys in Upper New York state.

    Is it the real deal? I just ordered some stuff last week from freestyle, which is always the trigger for them comming out with new products...

    Microdol-X doesn't seem like a very complicated developer, so it would be unsurprising if it couldn't be easily reproduced. Kodak may have used some additives to compensate for different water supplies, anti-caking agents and such, but the basic formula isn't so unusual.

    I have the ingredient list (not the formula) sitting right here on my computer desk. If it does not match that, it isn't the same thing!

    MSDS data does not need to include proprietary chemistry nor does it need to include chemistry below a certain level.

    If you go here: http://www2.itap.purdue.edu/msds/docs/9722.pdf

    You will see the difference in the MSDS. This does not tell all. What interests me is, why does anyone care?

    It would make things easier for those who are used to using Microdol-X

    Then the best way to test this premise is to make a side by side comparison of the two developers. If they don't match, then you have the answer to the OP. Otherwise, we really don't know and there is no way to know unless the respective formulas are published.

    One problem with Microdol-X is that the formula has changed slightly over the years, at one point it included Sodium Citrate, now it has Boric Anhydride (Boric Acid) instead.

    As Ron (PE) has pointed out before it contains an anti-oxidant, some Kodak films in the 1960's suffered from Dichroic fogging in Microdol which necessitated the addition, Ilford films where unaffected according to a UK article (early 60's).

    D23 with 30 gms of Sodium Chloride (Iodide free) is a good substitute for Microdol-X and works perfectly with Ilford & Foma films giving results very similar to Microdol-X or Ilford's equivalent Perceptol. I haven't tested it with Kodak films but in answer to Ron's (PE) question "What interests me is, why does anyone care?" people want to make up their own substitute and I do know people using it successfully and the quality of their prints is outstanding.

    PSInc is the vestiges of one of the US photochemical manufactures, they still make colour chemistry as well as some of Freestyles products.

    Well, unless the MSDS isn't mentioning something - no, it is not Microdol-X.

    It is the original Microdol formula - which anyone can make. If you use this with modern films you will get dichroic fog. I'm rather startled Freestyle would sell something that is guaranteed to have problems.

    Kodak's M-X MSDS gives (figures rounded)

    75 S. Sulfite
    20 S. Chloride
    3 Metol
    1 Boric Anhydride (boric acid)
    1 S. Hexametaphosphate (calgon)

    The freestyle product leaves out the last two ingredients, as do many versions of Kodak's MSDS.

    It also seems that the Kodak MSDS may not be mentioning the presence of benzophenone:
    see US Pat. 3161513 http://www.google.com/patents/about?...BAJ&dq=3161513

    Though if Kodak is leaving all these things out of their disclosures, so maybe is the maker of
    Freestyle's product.

    I remember when Microdol became Microdol-X. Was this an actual change in formula, or just a change in nomenclature?
