I am looking for a recipe of ‘artificial human sweat’ to use in corrosion
experiments.
I used to have an extensive recipe, but that’s lost. Somebody gave me a
simple recipe:

1 liter H2O
5 gram NaCl
1 gram Urea
1 gram Lactic Acid
.... NH4OH (to adjust pH to 4.5 - 5.5)

I am looking forward to a recipe with more ingredients.

Thanks, Kees Broek

The pleasanter smelling sort seems to have some sort of orange or citral
fragrance. Or is that from the soap the clothes are washed in?

As I recall the textile industry has 'standard' sweat recipe. I think
the American Association of Textile Chemists and Colorists (AATCC) had
some formulas.

If you can find the patent on Gatorade you will have the recipe you want.
That product, less the sugar and flavoring, is based on the composition of
the
sweat from the Florida Gators football team.

International Standard ISO 105-E04:1987(E) determines testing for colour
fastness of dyed textiles to perspiration.
There are two types of human sweat: alkaline and acid, dependent on type of
human skin.

Alkaline solution (artificial human sweat) containing, per litre:
- 0,5 g histidine monohydrochloride monohydrate
- 5 g NaCl
- 5 g Na2HPO4×12 H2O
- 2,5 g Na2HPO4×2 H2O
The solution is brought to pH 8 with NaOH (0,1 mol/l).

Acid solution containining, per litre:
- 0,5 g histidine monohydrochloride monohydrate
- 5 g NaCl
- 2,2 g NaH2PO4×2 H2O
The solution is brought to pH 5,5 with NaOH (0,1 mol/l).
