Honestly @muth I’m not looking for scratches, but I don’t scrub mine either, only soak in warm soapy water 24 hours, rinse, soak in clean water 24 hours, then rinse, and dry. If I get one that DOES get wrinkley, I just toss it, and grab a new one.
I mentioned permeability of the LDPE, BUT, let’s talk about “breaking down”. Remember hearing about certain flavors “eating” bottles ?? Def. cinnamons, some citrus/lemons, and more. PET is hardened, and holds up to about everything we (DIY) can throw at them.
Some more info …
The 4 types of material
LDPE – Low-density polyethylene. This material is what they make the really squeezy, thin plastic bottles out of. LDPE is defined by a density range of 0.917-0.930 g/cm3. It’s not reactive at normal temperatures except by some solvents or strong oxidising agents.
HDPE – High-density polyethylene. A very common plastic used in many different applications, from milk bottles to fuel tanks for vehicles. HDPE is defined by a density range of 0.930-0.970 g/cm3. It can withstand higher temperatures and is less reactive than LDPE.
PET – Polyethylene Terephthalate. The strongest, most rigid and least reactive of the plastic bottles used for e-liquid. Commonly used for short fill bottles.
Glass – Doesn’t really need an introduction does it? I like mine with bourbon and coke in.
The truth is that any of these materials are absolutely fine for holding e-liquid. For long term storage, I would probably steer clear of LDPE bottles though, as depending on the e-liquid contained within them, you may run into issues if you’re planning to keep the e-liquid for several months/years.
All of the constituent parts of e-liquid are stored and sold in HDPE or PET bottles from the manufacturer. This tells me:
The manufacturers are guaranteeing that the bottle material will not react with the ingredients over the given time frame (best before).
If plastics truly do leach into e-liquid all of the ingredients are already fucked at the point of manufacture.Of all of the ingredients in e-liquid, it is the flavourings that contain the most volatile chemicals. So, if Capella are happy to manufacture, store and ship in HDPE bottles then logically, the same ingredients further diluted, should pose even less of a risk.
People who talk about plastic bottles leaching into e-liquid when referring to PET or HDPE bottles are talking nonsense. Chemists often keep acids in HDPE and PET bottles or beakers because of how unreactive the materials are. Does nobody remember the scene in breaking bad where they dispose of the body using hydrofluoric acid? Walter White knew. I’ll take the science of a fictional, cancer stricken chemistry teacher turned meth dealer over bro science any day of the week.
