    Substitute for Edwal No-Scratch - Glycerine?

    Sooner or later I'm going to run out of this stuff,which is unobtainable now in this part of the world.
    I've tried Glycerine,but it is too viscous.
    Could someone suggest a suitable dilutant ?
    I need something a little more heavy-duty than noseoil..

    I think Edwal NoScratch has turpentine in it. You could try that. Its oily, but cleans off well with film cleaner.

    Nose skin oil (yes, really) will be a good replacement. It has approximately the same refraction value as film.

    Yes, nose oil does work and so does turpentine, a componant of No Scratch.

    Glycerine is water soluble. Perhaps if you thinned it a bit?

    You don't want to use anything that has water in it, as this will cause the emulsion to swell and become fragile. Your best bet is to use a petroleum based product, turpentine, if you can't get No Scratch.

    Any type of light mineral oil type substance should work to temporarily fill in the scratches, and then can be removed with film cleaner, which is a solvent that removes oils.

    Propylene glycol is thinner and might work alone. It certainly can be used to dilute glycerine.

    I don't think just anything can be used. The index of refraction must match the film base pretty well.

    I don't think I would suggest turpentine. It tends to get sticky with age. Glycerine sounds better, but nose oil is best.

    We used it at EK. Of course, just being a Kodak suggestion might disqualify it to many of you. My first boss had an imposing nose, source of much oil used on negatives at EK. He liberally spread it around when needed. He was head of the Negative, Positive Color Development Lab.

    One more vote for nose oil. Clean it off right away with film clean.

    Hard to use nose oil if you are printing 100 negatives in a session.
