Compatibility of Carbopol 940 and benzalkonium chloride
The only info I found from Lubrizol only suggests that 0.1% benzalkonium chloride lowers the viscocity of Carbopol 934. Nothing about compatibility.
benzalkonium chloride is a cationic surfactant and Carbopol is anionic I believe. Will a concentration of 0.13 % still have a negative effect in my formulation?
I know Guar Gum is usually used (from patents I read) but I need to know if BZK is compatible with Carbopol in small concentrations.
Thank you.

@Cafe33 I guess it is difficult to have stable product as Carbomer is not stable with almost cationic surfactant, may the low level of BZK will lead to stable product.
I invite you if you can to do experience and see what it gives -
Hi Fekher, I will most likely be doing the experiment but unfortunately I need to purchase 25kg of BZK. It has many uses, possibly as a cleaner in spray form.
I read a patent about a no rinse surfactant based hand and surface cleaner utilzing BZK.
It is basically 95% H20, Surfactant, 0.1-1.0% Defoaming agent (many polyquats are listed), BZK in 0.08 - 0.25% and a preservative. I will update here if I decided to purchase and proceed.

If you are planning on making this product as a method to combat Corona virus. Please DO NOT.Benzalkonium chloride has limited activity against this virus. -
ozgirl, thank you for the information. I am not suggesting it is for Corona virus. I am trying to work with what I have.
I used to sell cases upon cases of BZK wipes to local hospitals when I had a medical supply business. I used it as an alternative to IPA wipes when I needed to take an injection,
So can we agree that BZK is a sanitizing agent, perhaps not for Corona Virus, but perhaps as a replacement for something like Lysol (cleaning surfaces) ?
Wouldn’t something that had a surfactant and required rubbing with a rag clean fairly well?
I am working with what I have and here people are running out of cleaning supplies and stores are limiting sales.

Sure, but it won’t work with an anionic carbomer.
Besides, for effectiveness it’s recommended to formulate a mix of surfactants. If you check prospector you will find lots of similar formulas, mainly for hand wash and surface cleaners.
It’s a good disinfectant, we know it works and it’s cheap, go for it.
@ozgirl sure, but not against this virus. This one hasn’t been tested yet. We are using the information we know of other similar viruses, and the data regarding bzc is contradictory, at least the papers i’ve read.
