As Belassi suggested, you should find some product references and check the list of ingredients (LOI).
Here is what I found:
Excipients: glycerol (glycerin), nonoxynol 9, citric acid anhydrous, disodium hydrogen phosphate, sodium hydroxide 10% solution (w / v) (for pH adjustment), purified water.

Easy, you can find the LOI and mixing procedure in practical pharmacology book of the 3rd year of any medical college.

Talking about iodine. They painted me with some weird stuff when I was in the Cath Lab. After, I couldn’t get it off for days and days. It was like a brown film stuck on to my skin, obviously contained iodine. They paint most of the patient with it during major surgery.

@Belassi that is 3MDuraPrep antiseptic surgical solution, its usually used to sterilize the surgical site, mainly skin. As you described, its creates a water resistant and wash off resistant film that can last for 2-3 days.

My friend Zaidjeber, in pharmaceutical book it is merely a formula for lab practice not industrial formulation. Do you have any recommendations?
Belassi you are right. I think the formula may contain xanthan gum so it will form a film on skin.
Duncan yes it is.
Doreen81 what i need to know is how to convert this lab formula to an economical long shelf life formula, especially it is for wound disinfection purposes.
So guys how doyou suggest to proceed?

Just for starters I doubt the formula you presented. It contains no alcohol. I don’t believe iodine is water-soluble. The stuff they painted me with was freezing cold, evaporated very fast, and I could smell the ethyl alcohol.
