MG Chemicals 403A 134A Super Cold Spray, 400g (14 oz) Aerosol Can

I found a growth near the right front should of a 5 year old Llaso Apso dog. He has hair, rather than fur, so requires grooming and I didn't want to work around the raised growth that is/was similar to a wart. I had speculum on hand that came with an otoscope and found that a 3mm fit tighly over the growth. I treated it three or four times (photo is after the first treatment) but it remained solid and the treatment was only killing the top surface. I decided to use a 4mm speculum to allow the freezing liquid to freeze the sides and a bit of surrounding skin. Treatment has been recent, and the growth has not come off yet, but I an now fully confident that it will.The unsatisfactory early treatments are only due to my inexperience of working the the Super Cold spray. Since I graduated to the larger speculum results are much better. I have treated it twice with the larger speculum and am pretty sure that it will be enough. Looking forward to healed smooth skin and it won't take long. See photo showing brownish color....Happy to have been able to treat him at home. He didn't seem to mind at all, and sat still in my lap while I held the speculum with thumb and forefinger and spray into the speculum. Overspray hit my thumb and forefinger and were cold but no damage. The liquid bubbled inside the speculum and froze it to his skin and the growth until it all evaporated. Very simple with a cooperative dog. I'm happy to have found it and can recommend, but it is nowhere near as cold as liquid nitrogen, but much less money and it is getting the job done.

This worked much better than I ever imagined it would to -- freeze off "skin tags," if you can believe that. I got my first "skin tag" (a small naturally-occurring skin growth) in a somewhat private area of my body (no names, please) and just felt that I could remove it as safely as my dermatologist for much less trouble and expense. I did not want to cut it off with a razor blade or even with sharp surgical scissor (too much blood and the possibility of infection) and the dental floss method was impractical in this particular location, and I would have looked silly with dental floss there especially if I were hit by a bus and taken to the hospital in my nice clean underwear, if you know what I mean. So I decided to use freezing which some dermatologist prefer. Here's how you don't do it, and here's how you should do it:- Don't just spray it on your skin willy-nilly. It actually freezes and kills the upper level of the skin. Imagine you've been in Antarctica for a couple hours without gloves on. It's really cold. I tried this "aiming" method and ended up causing some really red skin burns that hurt.- Don't try cutting a hole in a piece of cardboard or paper and pushing the skin tag through the hole so you can freeze it. That sounds like it should work, but you'll end up spraying a lot of the freezing liquid through the hole onto your skin (and see above for the damage you'll do to your skin).- Here's what works. Get a straw. Cut it so it's a couple inches short since you want it close, but not too close, to the skin tag. Put the straw over your skin tag and kind of squeeze it both into your skin (to prevent leaking) and tight against the skin tag. Now, with your other hand (you're doing this alone, right?) put the nozzle of the can into the straw, but not all the way down. You don't want to "flood" the straw too much or the liquid will leak out of the straw and cause skin damage where you don't want it.- Spray in short bursts -- over and over again with a slight pause for some evaporation in between each one. The idea is to absolutely freeze the skin tag to death over and over. I sprayed 5-10 times. Not sure if you could do less or not. It pretty much hurts a lot, but it's bearable. Maybe the first time do it only once or twice to get used to it. Repeat the next day or two, if you need to.- Wait a week or so. The skin tag will die (you've killed the cells, after all)( and fall off. Repeat on the remnants if you need to. Apply some good skin cream periodically and a bit of antiseptic can't hurt, either. It really does work.

This works if you use it correctly. I sprayed some into a plastic cup as others have advised, then used a long Q tip to apply it to the area I wanted frozen off. The other important thing to know is that you need to leave the saturated Q tip on your skin for a few seconds until you feel a strong stinging sensation, then don't remove the Q tip until it stops stinging. It's scary at first because I thought it might freeze my skin too deeply if I left it on that long, but whenever I didn't, the spray did nothing. This spray after letting it do its job never froze off more skin than I wanted or went deep enough into my skin that it damaged it. I removed lots of brown spots, scaly areas, and bumps. Sometimes after the area healed I had to repeat the process again or several times but sometimes it worked the first time. I'm thrilled to have found this, especially at my age, where I was beginning to develop more sun spots on my face from too much sun exposure in the past. My dermatologist wouldn't remove them as they weren't enough of a skin cancer risk but I hated them and now my face and hands are almost totally clear. Some bumpy stuff on my body hasn't gone away by using the spray so I'm going to repeat the process a few more times on those and may have to pay a dermatologist to remove them but on my face this stuff has deleted most of them.

Cold, on average -55 but you hear peaks above -60 It made a nice bubble, let's see what happens in a few days, because the nitrogen gets to -200 and it didn't form bubbles but it resolved, but the price of the clinic? almost 1k per visit. Be very careful, don't let it run down the skin, I'm using a small funnel technique.

I haven't used it yet but this is like a loophole product for people looking for 1,1,1,2-Tetrafluoroethane. You just need to buy a side can tapper and maybe a recharge hose/manifold gauge set. I can't use the R12a products because I have a hybrid/HV compressor so I need straight 1,1,1,2-Tetrafluoroethane.

I have not used this yet , but have used MG Chemicals products before and they have always been topquality

merci pour votre bon service !

Works good and can't beat the price.

Exactly what I was hoping for... Works great!
