I've read that you shouldn't use ferrous utensils, like metallic spatulas, spoons etc. with L-ascorbic acid.
But does that also count for the derivatives?
Example: I use 2-3% sodium ascorbyl phosphate in an emulsion. Can I use my ferrous spatulas during the preparation of the emulsion?

But what I mean is this. Standard pharmacy utensils:
I am used to preparing emulsions, ointments etc. with a metallic spatula and 'mortar scrape cards':
I tried to work with plastic spatulas, but I can't work as precise with those as I can with metallic spatulas (plastic ones are too thick, too much loss of product and thus active ingredient).
I sincerely hope that I can keep on using the metallic kind with vitamin C derivatives! Thanks in advance for answers!
Thanks so much for your answers!
Glad to read I can keep on using them.

The spatulas are made of stainless steel, but even stainless steel can oxidize over time, especially when (strong) oxidizers are used.
One of the stainless steel laminar airflow (downflow) benches at my work needs to be neutralized with a sodium hypochlorite 5% solution every time when Botox injections are prepared in it (even when there hasn't been clearly visible spillage). The bench looks awful now, all rusty!
After a while it is replaced by a new one. The costs must be enormous...
To think about all the precautions we take and there are even 'Botox parties' by (mostly) women at home! They obviously have no idea what they're dealing with!
Edit: typo
A wooden spatula?
@Pharma
Yes it is, because we use sodium hypochlorite. Or did you think that I thought that Botox causes rust?
I know from higher up they're busy changing protocols on i.a. the Na hypochlorite causing corrosion. And yes, due to the chlorine! Weird right? I mean if you get a whiff of sodium hypochlorite, you'd never guess chlorine! Totally free from odour!
Also a change on the 70% IPA we use to sanitize the whole benches (I indeed have heard rumours of using H202 one week then IPA the other).
Another shitty thing regarding nasties. The lab recently has found a fungus in this particular clean room where toxic steriles are made (mostly chemos). Fungi are the biggest horror scenario here as you can imagine.
No idea what the plans are yet...
@Fekher
Ok, thanks for mentioning! I think I'll stick with my metallic spatulas as I love to use these!
@Dtdang
You're welcome!
