Iodophor question is /same as betadine solution??
Question:
– Hide quoted text — Show quoted text – The betadine says povidone-iodine 10% My handy bottle of B-T-F reports: Active Ingredients: Butoxy polypropoxy polyethoxy ethanol-iodine complex (providing 1.6% titratable iodine) …. 12.54% 10% povidone-iodine is about 1% titratable iodine. Note that it’s not "… ethanol-idodine …" There is no ethanol in that product, but instead a non-ionic detergent called " Butoxy-polypropoxy- polyethoxyethanol". The complex would be better written something like "…polyethoxyethanol/iodine". Pierre
Response:
I’m wondering want exactly is the difference between iodophor santizer and betadine solution used by most hospitals, I have a large supply of betadine solution avail/to me and was wondering if I can use this in place of iodophor? The betadine says povidone-iodine 10% inactive ingredients- citric acid,dibasic sodium phosphate,glycerin,topical antiseptic bactericide/virucide To any of you chemists out there is this the same as BTF? LOOKs exactly the same but not too sure will it work for sanitizing or is it totally different? Thanks
My handy bottle of B-T-F reports: Active Ingredients: Butoxy polypropoxy polyethoxy ethanol-iodine complex (providing 1.6% titratable iodine) …. 12.54% Inert Ingredients: … 87.46% Immerse 2 minutes. 1/2 oz per 5 gals – 12.5 ppm. 1 oz per 5 gals – 25 ppm. As to whether B-T-F’s 12.54% is roughly the same as your 10%, so use the same amount, or whether B-T-F’s 1.6% is a lot less than your 10%, so use less than one-fifth the amount, …. I dunno.

10% povidone-iodine is about 1% titratable iodine.

The problem with betadine and other disinfectants is that they do too good of a job. Trace amounts will kill off the yeast. I can say most certainly that rinsing 3 times with hot water may not be sufficient to rinse away all the residue, depending on the type.
Plain Betadine used at the proper concentration, 12.5 ppm, is an efficient, no-rinse sanitizer. It does not kill any more yeast than any other iodophor. Pierre — Tired of TV reruns? Help is on the way! New York City | Home Office Beer Guide | Records http://www.nycbeer.org/ | http://www.web-ho.com/

some iodine based products like TEAT DIP contain things you don’t want in your beer,
I would think that would be a problem with a product like Betadine, too. It’s made to scrub skin, and as such, has stuff in it to reduce the drying effect a harsh cleaner would have. I don’t have the ingredients in front of me, but I recall the original poster listing glycerin. Those moisturizing agents would coat everything they came into contact with, and be a PITA to rinse.

The problem with betadine and other disinfectants is that they do too good of a job. Trace amounts will kill off the yeast. I can say most certainly that rinsing 3 times with hot water may not be sufficient to rinse away all the residue, depending on the type. This defeats the purpose of iodophor, in which trace amounts of iodine are ionized by the beer wort. I don’t use Iodophor too much, I go down to the local Dairy supply store and buy a highly concentrate iodine tincture for $26 a gallon, lasts for years. Check the ingredients carefully, some iodine based products like TEAT DIP contain things you don’t want in your beer, such as lanolin. Dave — Relax, have a homebrew, use a Bozo filter.

"Iodophor" is a general term that covers hundreds of preparations of iodine with a detergent-like carrier. Povidone-iodine is an iodophor (in fact it is the original iodophor); Betadine is a trade mark for disinfectants based on the povidone-iodine iodophor. In addition to the active iodine they contain various other active and inert ingredients; the one you describe is used to disinfect the skin in operating rooms, hence the glycerin, etc. I’m not quite sure where that "topical antiseptic bactericide/virucide" comes in. Is it a description of the Betadine, or is it an additional item in the list of ingredients? If the latter, I’d stay away, not knowing what it could do to yeast and/or flavor. If the former, go ahead. 12.5 ppm of available (total) iodine for a no-rinse solution. Soak for 5 minutes and let drip thoroughly (no need to let dry). Pierre — Tired of TV reruns?

BTF Iodophor’s active ingredient is an ethanol-iodine complex. The active agent is just over 12 1/2 % titratable iodine. BTF does not list the "inert" ingredients, but I do know that it is a "low foaming" formulation. I am also pretty certain that BTF does NOT contain any glycerin. I would imagine that betadine would work as a sanitizer, but have no idea if you could simply "air dry", or if even rinsing the items would effectively remove the residue.
