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. -
What will be product(s) pH?
K903 has some efficacy - tho’ supplier’s “extremely effective is BS.
forget Neodefend.
Don’t count on Benozate alone - don’t know what theory justifies but that’s prob. irresponsible.
If not freshly prepared - 6-12 hours - or frozen and thawed, the extracts are a big micro risk and need preservation - K sorbate needs pH adjustment and is pretty weak. -
6.5 is better - 7 is ok. NOT lower than 6 - it’ll evolve chlorine gas and that is a very bad health risk. 20-30 minutes - recirculate if you can. Commercial liquid bleach is usually ~ 5%.
you can buy test strips on Amazon
Water - you need to rinse out the stuff with water no worse than process water - NOT tap water. Start production - fill with product no more than 6 hours after sanitization.
What is composition of your system? Stainless steel? PVC? Y
Clean it before you attempt to sanitize.
You should wear eye protection.
-
100 ppm available chlorine pH ~6.5 BUT NO Lower than 6 is a good sanitizer. Rinse with process water.
-
better idea
-
Under stand the preservative combination but have no experience or data for the minimal CMIT level.
For sanitization - what about hypochlorite?
-
Sorry - my comment before was in ref to both at effective levels. +
Why not sanitize? Preservation - even pumped up - fails to poor hygiene. Can you describe your sanitization challenges more specifically.
