Is the plastic in the cap resistant to acetone?

Unsure Mike; I'm using them for habanero sauce with a vinegar base--probably as acidic as acetone. I thought the seller was responsive when I had questions. I'd reach out to them.

Yes, the clear plastic goes inside the bottle. There shouldn't be any leaks

yes....but the part that pushes down into the bottle is plastic. But I am told the citrus oils do not break it down.

Yes they do come with the container and no the acetone does not eat through the plastic.

It keeps the cotton ball with acetone inside of the cap, but the acetone breaks down the pink rubber part of the soaker.

I just looked and while most of the cap is plastic, the part that touches the water is steel, and then there is a gasket. So the only plastic that would touch water is a little bit of the gasket seal which insures water proof. This is a quality item of very good manufacture, I love it.

Yes,bottle is tightly protected by cap. Also bottle is in box and securily wrapped. Don't worry, perfectly safe.

No, no plastic. The stopper is rubber and it tends to degrade a bit (get somewhat sticky) over time, but no plastic.

The question about the caps is irrelevant for its application, because there is a semi-transparent liner embedded in each cap that comes in contact with the glass bottle throat, thereby creating the seal. I understand from something I recall reading that material does not contain BPA (Bisphenol A) which is believed to cause cancer. The black cap material itself is rigid and sturdy, and holds the semi-transparent liner. I will say that I do not believe these caps - or the glass bottles they stop - are intended for intense heat. Therefore, when you say "Penolic resin are thermosetting materials - you cannot re-melt it," it's a puzzling question in the context of the represented intended use of these caps.

Both the bottle and the cover are #2 HDPE plastic and as far as I know BPA is only found in plastics with the #7.

The caps are plastic. I see Deb says the gaskets are glued on, but that (at least in my case) is a false statement. The rubber gaskets are removable and in fact I may change them immediately as they seem less sturdy than the rubber replacement washers I bought for other bottles.

Yes. The only non plastic part is the metal screen and the inner glass layer. The cap (two parts) are made of plastic and there are rubber rings too. I have deemed the product acceptable for my personal anti-BPA standards. After nearly a year of constant use, the plastic cap still weighs the "same" so if it is degrading into my drinks, then it is happening at less than one part per billion over a year.

The water tank is Polypropylene. Which is generally considered a very good chemical resistant material. It is certainly not cheap plastic. The instruction manual says the following for material: Cap; Porcelain; Base; ABS; Sink; PP; O-Ring; Silicone; Lens; PC. I don't know what essential oils you will be using but I suspect it will be fine with most normal essential oils. Some experts will say that citrus essential oils such as lemon and orange should not be used in a plastic container. But as I said, polypropylene is a tough, chemical resistant material and should be able to easily stand up to dilute citrus oils.

The cap is made of BPA free plastic, and it is not lined with stainless steel. I do not own any Klean Kanteen bottle, I am not sure the Klean Kanteen loop top will fit and seal this bottle.

In a word, yes. In the fine print on the back of the individual pcket is a caution statement which reads: Contains isopropyl alcohol.

Did you check the company's website? In the FAQ's section it clearly states: "Our pour caps are made of FDA-approved BPA-free number "5" Polypropylene plastic. While it is not the organically-derived (i.e. plant/bio-based) plastic typically used in disposable products, it is recommended as the safest choice for food and beverages." If this is not sufficient details for you, then contact the company directly. Because the food is in contact with the lid only briefly and we do not heat the lid, I am not particularly worried about possible leaching. I'm so happy to have a lid that works!

When you see the white cap it is plastic and the jar may be plastic. When you see a metal cap it is usually on a glass jar. Not sure if the Kelapo plastic is BPA free
