This is a bit of a newbie question. However, I have not had to deal with it before and am a bit flummoxed. My fragrance oils have been shipped in glass bottles through previous suppliers. However, I placed an order recently in which they arrived in HDPE plastic. I would like to transfer them to glass for obvious reasons. Herein lies my problem.

Searching Amazon for amber glass bottles with poly caps, I have come across a variety of options that do not appear to be the equivalent. Which ones are appropriate for my purposes?

Option One:
The Wheaten bottles are made of soda-lime glass in which they state, "Soda-lime glass type conforms to United States Pharmacopoeia (USP) Type III requirements for solvent, chemical, and sample storage, such as some dry powder types, and in dry-heat sterilization applications." (

Option Two:
The JG Finneran bottles are made of borosilicate glass (

Option Three:
Another alternative is these Packer bottles that are intended to be used with volatile solids. I like the idea of decanting more easily into the larger openings and being able to utilize them for some of my dry ingredients such as stearic acid as well. I am happy to pipette the fragrance out of the larger openings. These are only identified as being glass with plastic screw lids (

Option Four:
These by Qopak cost a bit more, but are identified as having a"black thermoset phenolic cap" (

I am happy to consider other options and am sorry if I am over-complicating a simple issue. I really tried to find an answer elsewhere to avoid sounding idiotic. Contrary to popular opinion, I believe that there ARE stupid questions. I just hope that this is not one:oops:

You don't have to worry about the type of glass you use. You can use any of the ones you listed for longer term storage of FOs. I would stick with a narrower neck to reduce evaporation. Take a look at SKS Bottles if you need a larger number of bottles and to check prices. I've bought from them before and they have quality products.

Don't confuse ignorance of a topic and stupidity. Ask away.

Right here, silly!
When transferring my FOs from plastic to glass, I use amber glass 'Boston Round'-type bottles with phenolic cone caps, and I buy them from whoever has the cheapest rate that I can find at the time. Sometimes I've bought them from WSP or MMS, and sometimes I've bought them from these vendors:
