anyone use naglene bottles?
whats the max temperature that they can safely withstand?

[SAS-1]

I use one but I've never heated it up. I can tell you from experience that it can withstand about a 5 ft drop onto asphalt. :lol:

[funkyfr3sh_]

I use them but I never have put them under high heat...

Just normal use...supposed to never break. Too bad that the cap is plastic and would probably bust off in a snap! They sell the caps though seperate

[UrbanPoet]

I just made tea with my naglene bottle... i dunno if its safe.
the water was 209 degrees F (not C... b/c that would be radiculously hot).

[jayisthebest88]

U can stick these things in a fir and they wont melt.....these bottles are almost indestruvtable..except for the cheap ass cap....I think I saw this on street cents :-0

[Oni-kun]

the bottle will not suffer but you may. Hot liquids will increase the rate of leeching. I would never use one of those lexan plastic bottles. they leach nasty stuff into the water.

"In 1998, Dr. Patricia Hunt of Case Western University in Ohio discovered that one of the components of Lexan polycarbonate resin--bisphenol-A (BPA)--can leach into water from water bottles. BPA is a potent hormone disruptor. It can impair the reproductive organs and have adverse effects on breast tissue and prostate development."

I also remember reading some study where they used lexan for water bottles for lab rats and some of them became infertile.

[UrbanPoet]

I thought these naglene bottles were resistant to "leeching"

[Oni-kun]

sorry "leaching", no they are not. only thing that doesn't leach stuff into water is probrably a glass bottle.

if you look on the naglene site they'll say its safe of course. What manufacturer would call their own product unsafe.

not resistant, but better than PET bottles...however if you're putting hot liquids in your nalgene bottle, all bets are off ...I wouldn't put hot stuff in any lexan bottle.

[UrbanPoet]

gotcha. No more tea in the bottle.

[lkn4deals]

gotcha. No more tea in the bottle.

Just get a stainless steel thermos type thing....just make sure it's lined with stainless steel inside and not plastic or aluminum...they're frequently on sale at Canadian Tire for $10 or less...

I noticed you failed to mention that the mice were actually living in the polycarbonate cage and that it was a harsh cleaner that leached the BPA out of the material and not the water.

A quick search of PubMed gives an articles from the Journal of Food Additives and Contaminants 2005 Mar;22(3):280-8.

Dietary exposure assessment of infants to bisphenol A from the use of polycarbonate baby milk bottles.

Onn Wong K, Woon Leo L, Leng Seah H.

Food Control Division, Food and Veterinary Administration, Agri-Food and Veterinary Authority, Singapore. wong_kwok_onm@ava.gov.sg

The residual bisphenol A (BPA) levels in 28 different brands of polycarbonate (PC) baby milk bottles available in the Singapore market were measured. With a detection limit of 3 mg/kg, BPA residues were detected in 19 out of the 28 PC baby milk bottles at levels between 4.01 and 141 mg/kg, with a mean of 28.1 +/- 31.4 mg/kg and a median of 17.2 mg/kg. The potential migration of BPA from each of the 28 PC milk bottles was also measured using food-simulating solvents and time conditions recommended by the US Food and Drug Administration (US FDA), but using temperatures more severe than actual use. The highest upper-bound mean BPA migration levels of 0.64 +/- 0.48 microg/in2 in 10% ethanol at 70 degrees C and 0.43 +/- 1.25 microg/in2 in corn oil at 100 degrees C were observed after incubating cut portions of the milk bottles for 240 h. With this migration data and using US FDA's procedure for estimation of dietary exposure, the worst-case dietary exposure assessment for the intake of BPA by infants between birth and three months of age was below the oral Reference Dose of 0.05 mg/kg bw/day established by the US Environmental Protection Agency. This study showed that the dietary exposure to BPA from actual uses of PC milk bottles is unlikely to pose a health risk in infants.

but milk is likely to be pre-heated or even heated in the bottle...so even if SOME bpa is leeching in it could be because of the heat/heating

[gamer123]

Just wanted to add that, these naglene bottles are DAMN strong/hard. I witnessed my friend throwing a big size one (empty) down to the ground with full force, it bounced up ~15ft and came back down. Nothing happens.


Sorry if this is a little off topic in an off topic thread :lol:

Look i'm not writting a term paper here. For all I care somebody can drink hot coffee and tea from one everyday if they wanted to. How does it affect me? It would not benefit me to be bias. So I missed a small detail.

[JimG]

The point is that very little leeching occurs. I think most people use PC bottles to store cold liquids anyways. Baby bottles are constantly being heated, washed, nuked and still they leech insignificant levels of BisA.

[GateGuardian]

a what????

Even so, I would NEVER heat anything in a plastic container...

Also, you might want to check out who sponsored that study...maybe a baby food company... :lol:

Hey, I'm simply providing an opposing view point, and the rest of the information .

[Oni-kun]

When I have kids i'm only going to feed them baby food from glass jars. And as for milk the baby can suck on a boob.

[lkn4deals]

Hey Ojam,

Isn't it time to lose the hat?

[Ojam]

right, most of these bottles are made for cold liquids, I would never put a hot liquid in one of these bottles, I have a stainless steal thermos for that.

[lkn4deals]

:rolleyes: um...you might want to talk to a woman about always sucking and not storing sometimes...

also, before deciding on only giving food from glass jars (I assume to avoid the plastic issue), you might want to check out the additives and preservatives in baby foods... :lol:

[Ojam]

Hey Ojam,

Maayyybe (looks around) ;)

Atleast this article was able to get published in a peer reviewed journal. I have yet to see any studies proving significant levels of leeching from polycarbonate bottles that's remotely credible.

Thats where the organic baby food comes in. Not completely free of that stuff but low enough to be certified organic.

I'm not trying to say it's not valid; I would want to know more about the researchers and who sponsored/funded them first...

[lkn4deals]

you're better off buying a food processor and giving the baby fresh food...

[deal_lurker]

Those Nalgene (Lexan) bottles are supposed to withstand a lot of things... I saw a show on TV where they dropped one from a very high place... froze water in it and then torched it (don't know how hot it got though)... but it came out pretty good.

In regards to leaching of chemicals from plastics... one has to be very careful what they read/hear... as I have heard some of the comments about plastic leaching into water/liquids via heat might be urban myths.

PubMed sucks hehehe, Web of Science is the way to goooo!!! Kiddinggg

[MrDisco]

this is one of those topics that pops up every so often.

conclusion: no one knows with absolute certainty. the plastic industry will say its safe, researchers will say there are risks. we'll probably die from something man-made anyway so pick your poison (cell phones, plastic bottles, mutant chicken nuggets, peanut allergies...)

:)

I tried Web of Science and Medline too, and they didn't really kick up anything relevant with a quick search.

[MrWizard]

I've never tried heating mine up, but I have taken one and thrown it around outside. Smashed it against a curb, threw it 30 feet in the air, let it crash down on the asphalt, it it with a baseball bat, etc. Nothing but a few scratches, and the cap wasn't broken either.

They're supposed to handle liquids up to about 130C.

[deal_lurker]

As I wrote in my post... "one has to be very careful what they read/hear".....

I am saying exactly that... regardless of what people say or say they hear (my self included) about stuff like this... they should take things with a grain of salt.

I know some of the stories about PET plastics might (keyword *might* be false).... I haven't read anything else on BPAs before this.
