Hey all. Haven't posted here before, but I'm a long time lurker, and I've been mixing for a bit over a year now. I was hoping to get an opinion from one of the more experienced DIYers.
Just received my first Wizard Labs flavoring order since August, and man, was I surprised when I opened the box. I've come to expect all of Wizard Labs' flavorings to arrive in stout, well-designed glass bottles, but this time was very different. All my 120mL bottles are strange, missile-shaped plastic bottles, and the 30mLs are about the usual shape, but made with hard plastic rather than glass. This wouldn't normally bother me enough to post about it, but I happen to know several of the flavors I ordered contain tank-cracking, plasticizing ingredients.
Part of the reason I've used Wizard Labs for so long was specifically because I knew they rebottle(d) all their flavorings in glass. Not only do they look nicer, but I know many of my usual flavorings don't fare well in plastic bottles, due to plasticizing ingredients (triethyl citrate, certain esters, whatever the hell is in Ripe Banana) or other corrosive chemicals. Surely Wizard Labs knows that, too.
Is Wizard Labs trying to cut costs? Or did I just order over a certain limit of flavorings, and received plastic bottles to prevent a shipping mishap?
Any input as to the safety of storing corrosive flavorings in plastic bottles would be appreciated. Also, if anyone else has received these plastic bottles from WL and is as pissed off as I am, is there anything we can say/do to get the old bottles back?
You can just ask them and they will pack in glass, I also posted this a week ago with a picture
I'm pretty new to the mixing game so I haven't had any orders show up that weren't in PET or HDPE.
However, I do work in a chemical laboratory and can give some insight into which bottles are safe. As long as they are HDPE/XLPE they should be fine for long term storage. You can reference this page for any other types of plastics. I believe the chart is on page ~~15~~ 16.
The ones that really shouldn't be used are PET, which unfortunately most of the companies are using. I have no idea why they think this is alright, but I would totally be willing to pay an extra 30 odd more cents for a glass bottle.
Edit: meant page 16! Also HDPE not HPDE
Edit #2: If you are interested in transitioning away from plastic bottles, I've ordered from General Bottle Supply before with success. I make me own cocktail bitters and give them as gifts and they work like a charm for flavorings too. I think I paid 10 bucks for 48 (not including shipping). I personally am not going to bother switching 10 mL size flavorings as I'll use them fast enough. Hope this helps!
The link isn't working for me. Why shouldn't PET be used? AFAIK it has a lower oxygen transmission rate than LDPE which should, to some degree, help lessen the degradation of concentrates over time.
The link should be sending you to the Chemical Stockroom Handbook pdf by Fisher Scientific.
The reason I mentioned PET posing an issue is the known interactions it has with common flavoring agents that contain problematic functional groups such as aldehydes, ketones, esters, and others.
To your point about oxygen transmission, all of the listed containers are fine as far as keeping oxygen out of the contents. The issue we are discussing is the interaction/reactions that occur between the containers and their contents. Hope this helps clear up any confusion why HPDE/XLPE is the best plastic choice and why PET shouldn't be used.
Edit: clarity.
TFA, Capella, FA etc. store all their flavorings in PET/HDPE plastic (from 4oz and up to a gallon). What the point of rebottle into the glass?
Are they dropper bottles? I've avoided WL because I prefer plastic dropper bottles. If they've switched to dropper bottles than this is great news. If not then I guess it's the worst of both worlds.
They did include dropper tips with the order. Rather nice ones, too. Only problem is that I measure with syringes, not dropwise.
Sadly, yes they've gone plastic :(
My last order with them (around T-day), I had added a note on the order, asking if it was true as I saw a post on a DIY group and asked them please to stick with glass. They called me and said they were going to all plastic (except for the 8mL vials).
So, all my stuff came in plastic bottles - I had to spent my time transferring every friggin' thing to glass bottles, labeling, etc.. The glass bottles were the reason I ordered everything I could from them vs other vendors - I don't see me ordering much from them going forward :(
does bullcity come in glass?
PET
