Hydroxylamine/Hydroxylammonium chloride instead of HAS in a colour developer?

[Athiril]

I guess another question for PE..

So HAS is used for a developer preservative and for other things in emulsions right?

It's the sulphuric acid salt of hyrdroxylamine.

What about the hydrochloric acid salt of hydroxylamine.

This appears to be used as a anti-oxidant and scavenger for other purposes.

Would this do more or less the same job for developers? And what about emulsions?

I am asking since hydroxylammonium chloride appears more conveniently available than HAS.

HAS (Hydroxyl Amine Sulfate) is a preservative for color developers. It is not used in coatings AFAIK. The sulfuric acid salt is preferred as it does not affect the vAg of the emulsion.

Do not use HA-Cl. Use HAS. OR, use Dimethyl Hydroxyl Amine Sulfate or Oxalate.
