How safe are silcone bottles

I am almost certainly the only one here that has not squonked though I have several RDA’s that came with squonk pins. I do use RDA’s pretty often but mostly for testing mixes.

I do not like storing anything in plastic though about half of my flavorings are still in the plastic bottles they came in. The others have been transferred to glass and is an ongoing process. In many I have never noticed any leaching but am sure that is occurring. However, whenever I order any CAP that comes in the soft plastic frosted bottles they immediately go into glass or within a couple of months are bad. (some)

I haven’t read or heard of any problems but would like to know.

I have not drank water from a plastic bottle in several years after attending a speech by Dr Helen Caldicot who lectured on the dangers of BHP in plastics.


Nope. You’re not alone!
There’s at least two of us! lol


Silicone bottles I use for squonking are supposedly food grade. On the other hand, all my juices are in plastic so i guess i’m screwed twice :stuck_out_tongue:


There is the rub. I’m currently involved in fabricating a device for juice making which led me to attempt to research “food grade” materials. That led me to ask about the silicone bottles and whether anyone knew of bad effects. But most of the information I have so far been able to find either disputes the existence of “food grade” standards or lists them as common uses without any such specific classification. What I am considering (currently using) are 316 stainless, PTFE (Teflon rods), and was considering using 6061 aluminum. For example, 6061 properties declare usage as “general food processing fabrication’” but other data states the possibility of pitting, discoloration, and effects upon taste which led me to shitcan that possibility.

Anyway searching for data and composition led me to question the use of silicone in vaping or juice making products. After all, aren’t our o rings silicone? One part of my device is threaded and therefor I need a seal to make it ‘clean in place’ and ultra sanitary. I tried a press fit and it failed my test. Tig welding is an option but I would much rather avoid this. I’m old and my eyes are shot.

I am wholly aware of lab testing and approval processes. $$$$$ But I don’t intend to manufacture or market anything. I know absolutely that 316 SS and ptfe are “e juice safe.”


I’m always reluctant to comment on interactions between materials. I was listening to a radio show on the way to work this morning and they were talking about airborn toxins from friction reduction chemicals like Teflon and Scotchgard among thousands of others. Seems the EPA has no standard for what concentration is considered non-toxic. I always think of the discovery that nuking in plastics is thought to be another cancer causing reaction. I always end up with the question how safe is safe. Great question as always. I kinda hope it’s safe. I don’t really want to worry about it. I’m tired of worrying.


Rephrase this/ 316 Stainless is safe as long as it is not overheated and loses it’s anti corrosive properties. PTFE is very widely used and the first "plastic’ used in food preparation. However, there are many claims that dispute this despite MSDS data and government douche bags claiming safe usage in contact with foods. Indeed, My wife’s restaurant uses UHMW (Ultra High Molecular Weight) polyethylene cutting boards for food prep. Health authorities dictate this. It has similar properties as PTFE but does not machine as well or have necessary strength properties for this application. I have used a lot of it. Both plastics have great resistance to abrasion and are super slick.

I just don’t know but we threw out all Teflon cookware long ago here at home. I have used PTFE coated magnetic stir bars for quite some time for mixing e juice. Nevertheless I misspoke- I do not know that PTFE is “absolutely safe.” Teflon was developed and is is made by DuPont for chistsakes. DUH.

All opinions welcomed and encouraged. Safety first.


I have to stick with @SmilingOgre in that I am not worried.
I would be smoking if I wasn’t vaping so… I already won.


Every liquid I buy comes in plastic bottles, VG, PG, flavour, Nicotine, I assume they have sat for quite some time already before I get them, if leaching is occuring it would be too late imo.


That’s actually an excellent point… I’m not only speaking to the safety of plastics and silicone containers and bottles specifically now.

What she said is why I decided to comment. A lot of people smoke. A lot of people put themselves into high-dB environments without proper hearing protection. A lot of people expose themselves to harsh breathing environments without proper ventilation and breathing protection. A lot of people drive vehicles with weak brakes or worn tires. A lot of people eat highly processed food stuffs. People fly airplanes and jump off cliffs too.

Point is, we humans are in harm’s way nearly all the time from some part of our environment. And 95% of that exposure is by choice. Even if there are negative properties and risks involved with storing potables in plastic and silicone, that doesn’t mean we are gravely in danger, or that we must find alternate options. And as she stated quite well, if the choice is vaping from a silicone bottle vs. smoking cigarettes, that’s by far the lesser of two evils.

I guess you could say someone who lives ‘off the grid’ and controls every aspect of their bodily intake is at less risk, but hey, you could get a disease from a bad moose that you speared and prepared yourself I suppose.

And I hope you realize I’m not dismissing your argument. It’s valid. I’m just suggesting that maybe it isn’t the grave worry you may think it is.


I have to applaud @mrpipes for bringing up this question and looking into this. I have assumed it is safe as it is an industry standard. That is not necessarily true as we have found in the past with other conventions. As @anon96380778 points out, there are a lot of calculated risks that we take which is just part of living as we know it. As you pointed out @Jose, this risk appears to be far less than others like smoking. While I choose not to worry about it myself, I also have to acknowledge the assumption of risk involved. I will also stay tuned as I feel I have the perfect person doing research for me. I don’t want to appear to be minimizing anyone’s opinion in regard to this. They all are valid to me.


I didn’t word it very well, but I feel that way exactly, and certainly acknowledge and admire the effort he chooses to do for this.

I’m not one of those “it takes a village” types, so I’m a lot more uninvolved in a lot of this sort of thing. Calculated risks is where it is, Oggie. Do what ya dig based on your own risk vs. reward scenario, all the way.

Sorry @mrpipes, I didn’t mean to make it look like I thought you were being foolish. Virtually nothing in life is 100% safe, so picking your battles is definitely important and not to be minimized. I really hope you understand I don’t think you’re being extreme about it.


No, these are all valid points and to be honest if this just involved my usage I wouldn’t be at all concerned about it. I asked and people kindly and honestly answered. I didn’t expect to reveal this but I intend to make a few of these available to certain people but will not sell them. That’s complicated in itself and I should not have co mingled the issues.

As far as silicone is concerned I personally don’t think I want to use it and attempting to search for “food grade” products we constantly hear about, I found them to be non existent as far as material classifications. With the plastics there is at least one flavor company that does recommend transferring to glass for storage and of course all nic suppliers recommend transferring to or supply glass containers. Don’t really have time to look it up right now. I was asking if anyone had experienced or have knowledge of problems involving plastics and vaping.

I agree with your statements. I have a long professional background in manufacturing and product development. That creeps up and and is damned near automatic for me. But all those processes and procedures is how 5 dollars in materials + labor costs turns into something costing the end user thousands.
I appreciate every response given.


I’m definitely interested in hearing about this. Recall that you’re posting this thread in the public facing part of the forum though…
