I think I answered the central question.
pH 3-8 is not an adequate standard and soap can be contaminated - esp. with additions such as milk. Obviously relevant contaminant has special capabilities.I’ll add my 1st experience was with a well known French milk bar in the early “80 prob with the same bug - Nesterenkonia wasn’t named until 1995

There are preservatives in this ingredient list. Preservative is there because it is needed. Soap, esp. with milk, can be contaminated and the pH is not necessarily enough to protect.
You’d need a pH of ~2 or less and ~11 or greater to assure protectionhttps://onlinelibrary.wiley.com/doi/abs/10.1111/ics.12401

Don’t store -it’s not that stable.
-
probably - keep pH neutral or slightly acidic
-
In what form is your finished product - solid/liquid/gel?
-
There also better than the odd combination
-
You can use combinations of others based on pH but would need testing
-
I referred to active concentration.
-
2000-3000 ppm is what I’d use
-
Matt - correction - think it was Oxadine A
-
What is the product?
-
It’s not so much the time/kinetics as continued wetness hopefully gets into cracks, crevices etc. There’s no way to know if that’s effectively accomplished - I’d stick with longer time.

Hey Matt! Introduced back in late 70’s by Angus, think it was formaldehyde releaser “Oxiban A”. worked pretty well.
Germall et al. already had the role so never got a foothold in the market. Recall only one product that used it back then - (don’t laugh) - Brylcreme. -
Make sure it’d clean 1st and try to not let the sanaitizing solution dry. Repeat spraying enough to keep it wet/damp.
Long term - as your business grows, consider a plan to implement https://www.fda.gov/cosmetics/cosmetics-guidance-documents/good-manufacturing-practice-gmp-guidelinesinspection-checklist-cosmetics. -
Keep it wetted.
Do you have a longer term strategy to lower micro risk? -
Use at least 2500 ppm - but parabens prob better.
-
No - don’t mess with packaging.
Objective is to maintain contact on all surfaces through 20 minutes. Can you use a spray ball?
-
Like DMDM H combination - and suggest EDTA as well.
-
You can try it
I agree - prefer parabens (0.2 methyl/0.1 propyl)/ -
try 100 ppm but you need to get it into the product - pretty insoluble.
-
Name is not consistent with structure. Structure appears to be didodecyl benzene disulfonate sodium salt and I doubt it would be a simple product of combination.
There is an anionic surfactant dodecyl benzene sulfonate sodium salt used as a commercial detergent - OSHA hazardous and a substantial irritant you’d not use in cosmetics. https://www.fishersci.com/store/msds?partNumber=AC325910050&productDescription=DODECYLBENZENESULFONIC+A+5KG&vendorId=VN00032119&countryCode=US&language=enThink the one you questioned would be worse.

Generally true for shampoo - cream/lotion susceptible to both.
-
Should be OK - think finished product levels
>5000 ppm benzyl alcohol and >2000 ppm each acid in solution.
PET - look for 7 day kill. -
Formaldehyde labeling would be required for formalin and in many countries and EU for formaldehyde releaser.
-
Right - with the timing but I’d rinse right after sanitizing so it doesn’t screw up your paint etc. - then apply 6-12 hour limit.
Plastic/paint will be your on going risk.
Process water - turn off the tap.
