NEUTRA Sul HP 41N HAS PEROXIDE IN IT, AND A PEROXIDE DEGRADES. THIS IS CALLED "HALF LIFE". how fast does Neutra Sul HP41N degrade? Weeks? Months?

Months. Peroxide degrades faster in higher concentrations; It's a 7% solution, which should remain usefully stable for quite some time, provided you keep it in a cool (&lt; 23C) place. I go through it at a rate of around a gallon per two months or so, so it hasn't been an issue thus far.

Hello Trish. It seemed to last abt 30 days. After abt day 35, I thought there was a big difference.

I searched bio verses combust online and the differences are between them. All I can tell you is doo-right box states that a plastic bag can take up to 1000 years to fully degrade. These eco-friendly bags dissolve in approx. 24 months. Want more answers, contact the young man Jonathon at dooright.com

Hello actually if you are referring to how long will it last once you mix the catalyst that is 4 hours but unmixed it has a shelf life of 5 years. Regarding the overall aging properties it should last anywhere from 18-20 years Thank you Greg

I have used basic H for 42 years -- all bio-degradeable - I wash and rinse my veggies with it- wash the dog with it I even washed the kids with it. My windows look great too Love it BGP

No white marks at all and can last 24 hours or longer. That's saying a lot for me! Sometimes my old deo quit working after 1 hour. I'm telling you, this stuff is great!I hope they never quit making it.

I think it's not the same. Most of the other products use peroxide to bleach, while this one used ammoniac.

Excellent question!I have gone over the bottle of "Perineal/Skin Cleanser" 1 Cleanse with a fine-toothed comb. NO expiration date noted. I also took out my jug of Aloe Vesta "Body Wash and Shampoo" 1 Bathe. NO expiration date listed.I have utilized and purchased these products for approximately 14-15 years and have never run into an issue of their become rancid looking or smelling.

I can not confirm a shelf life. From what I found the lifesaver bottle is the best water purifying option on the market. The preasure you get out is the bat I have seen and read about. That was the deciding factor for me.

a quick google search says 2 years, very stable, slow oxidizer. This was a great question. I doubt a bottle will last that long!

Octenol is recommended for Northern or Coastal regions of the US. One cartridge will last approximately 21 days. The "3" designates that three cartridges are included in the box.

I can't help with the shelf life question because I always use it up rather quickly. My dermatologist recommended it and after my first purchase, I was sold! A great product to use under foundation or by itself.

Hi Karen, here's what I found out (its 12%): To answer these questions, we need to understand a few things about how teeth bleaching actually works and also look at each molecule and understand the chemical reaction(s) that takes place when the bleaching occurs. Tooth bleaching today is based upon hydrogen peroxide (HP) as the active bleaching agent. Hydrogen peroxide is noted chemically as "H&#8322;O&#8322;", and is a relatively unstable molecule by itself, and will quickly disassociate into highly reactive, strong oxidizing agents through the formation of three types of free radicals (hydroxyl radicals, per-hydroxyl radicals, and superoxide anions)[ii], reactive oxygen molecules, and hydrogen peroxide anions.[iii] Hydrogen Peroxide, in a gel substrate, may be applied directly to the teeth, or it can be produced in another chemical reaction from the more stable Carbamide Peroxide (CP) in the presence of water.[iv] Carbamide peroxide has two portions, the Carbamide portion and the Hydrogen portion. In equation 1, we see the Carbamide Peroxide molecule on the left side of the arrows, which is made up of the carbamide portion (H&#8322;NCONH&#8322;) bonded (*) to the hydrogen peroxide (H&#8322;O&#8322;) portion of the molecule. In the presence of water (i.e. oral saliva) it disassociates into free carbamide and free hydrogen peroxide. Carbamide Peroxide must go through this initial step before any bleaching can occur because it is only the free HP that actually does the bleaching. This takes more time, but Carbamide Peroxide is much more stable than Hydrogen Peroxide and also has a much longer shelf life. Also, it should be noted that a 44% solution of Carbamide Peroxide disassociates into an approximately 12.6% concentration of Hydrogen Peroxide, which equates to an approximately 3.5:1 ratio of Carbamide Peroxide concentration to final disassociated Hydrogen Peroxide concentration.

I keep mine in the frig. I think it will last a long time. It's mostly peroxide.

Hi. There is a 1:3 ratio of hydrogen peroxide in carbinute. 10% peroxide. Hence your faster whitener is hydrogen peroxide.ZOOM works wonders, just be careful of your gums. I put the gel on my teeth half way up and let tray push whitener up. I cover my gums with blister. That is how strong it is...I hope that helps.

Per their website on this product: "Our Vitamin C is derived from Sodium Ascorbyl Phosphate, which is a highly stable form of Vitamin C and does not oxidize for 24 months. We also make this serum freshly on a monthly basis. As long as the bottle is stored away from direct heat and sunlight, and the lid is kept tightly closed when not in use, then the serum should not oxidize for at least a year."
