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.

MemberJanuary 28, 2022 at 4:21 pm in reply to: Dimethyl oxazolidine preservative? Calling Dr. Phil.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? -

No - don’t mess with packaging.
Objective is to maintain contact on all surfaces through 20 minutes. Can you use a spray ball? -

MemberJanuary 27, 2022 at 11:10 am in reply to: Methyl Paraben vs IPBC comparison as anti fungal in lotionYou can try it
I agree - prefer parabens (0.2 methyl/0.1 propyl)/ -

MemberJanuary 26, 2022 at 11:03 pm in reply to: Methyl Paraben vs IPBC comparison as anti fungal in lotiontry 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.

>5000 ppm benzyl alcohol and

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. -

MemberJanuary 25, 2022 at 12:00 pm in reply to: Using milder preservatives with high % of plant extractsWhat 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.
