This encap must contain something stronger than 40vol

The jug bloated big time on its way up and over from Vegas.

I opened the cap to relive the pressure and shushishugarmamma!

eet BURNS!

I used to order that stuff from Steve...they'd be getting pregnant looking by the time they arrived. Some of the jugs were so bad that they became completely crystallized in a few days... Or at least half of the bottle would.
I stopped using it for that reason. Seemed to be very unstable.

I may need to give it another shot - hopefully they changed it up a bit over that past couple years.

I also don't recommend using it on wool... Even though they say it's safe for most wool.

This is a problem with any encapsulant with H2O2. If it gets placed on its side during shipment, then the polymer plugs up the vent and pressure builds. Heat compounds the problem. We have a warning on a yellow label on the top of the box of Encapuclean O2 and Peroxicap for instructions on how to handle the issue. For this type of product it is better to pick up from the local distributor who buys product in pallets where it will not be shipped on its side. I have tried without success 3 different vents to see if we could find one that the polymer would not stick. Trucks represent 90% of our shipping and result in 10% of our shipping damage. Non pallet shipments represent 10% of our shipping but provide 90% of our damage. The percent of damaged shipping overall is very small, but the bulk comes from non pallet shipments.

Tom I used to use encapucleanO2 but got complaints about the odor. I know my dist said to bring them in for a replacement but I think the same thing will happen just by sitting on my shelf.

Also that encapucleanD2 doesn't dry into crystals but is more of a film former. All my petry dish drying results in a hard shell that sticks to the bottom.

Peroxide in any formula does have a shelf life in terms of both stability and odor. Heat will shorten that time frame. It is best to order in smaller amounts according to your usage. I would never order more than a 2 to 3 months supply. The O2 is much more than peroxide as there is alot of polymer and some solvency to give it that cleaning pop. The synergistic combinations may shorten further that odor shelf life. One supplier is trying to invent a stablized peroxide for both strength and odor control.

I have never concerned myself in regards to crystals or film formers. They both work, and I doubt if anyone would really be able to determine any differences in performance based on that fact alone. Concentration, mix of surfactants, solvents, etc. explain differences between product not the type of polymer. I was adding a surfactant to a film forming polymer one day in the lab. The result was a crystal and not a film. For our polymer, I could create a crystal from mixing a film forming polymer with a surfactant.

The popular test of pouring the concentrate in a petri dish and letting it dry overnight tells you alot more about the concentration of the product than the nature of the polymer. If you have a products with 40% solids versus one with 20% solids, don't you think it will take twice as long for the more concentrated product to dry out. Also we are not cleaning petri dishes, but carpet. Testing should be done on carpet in ready to use concentrations.

On another note, I investigated a product claiming to be 3x a few years back. I did a dry down in my lab oven comparing it to our Encapuclean Green DS.
I weighed the remaining solids and found out that if the product was really 3X then we had been misinforming our customers for years about DS. Based on that 3X standard then our product was not 2X (DS) but in actuality was 6X. Thanks Jimmy for given me the opening to vent!!

Could the change in altitude have affected the jug, causing it to bloat? If so, then the peroxide isn't doing anything unexpected.

Oh, so that's why it can't be shipped on an aeroplane. :oldrolleyes:

But in the luggage compartment which is not insulated, wouldn't it freeze and not expand?? :marty:

'cos up there at 40'000 + feet, it would be about -55f which is pretty cool.

:yoda:

Shorty, back when I supervised container loadings, we had rules about proximity including what cargos were allowed above others in case of leakage. To me it looks like a business opportunity if you can't get US products.

Know any good chemists?

My previous post re aeroplanes was "tongue in cheek" sort of what you guys call :stir:ing.

Old Coastie, there are many, many products that we don't get down under.

It's only recently that we've been able to get Hydrox, I got my first bottle a couple of months ago.

Good chemists??

Not in my neck of the woods, I'm about 1,100 - 1,200 miles from our capital city.

A small city of about 150,000 max; with no manufacturing plant.

+ at my age, I'm slowing down, preparing to do a Rambo. :winky: :winky:
