Can I store boiled linseed oil in hobby syringes?

I don't do full-on woodworking. I just repair and restore stuff and would like to restore/patch/upgrade a large amount of wooden and metal boxes, tools, etc.

This means I probably won't use large amounts of the stuff and generally when I have a liquid that I only need in small amounts, I transfer it to a hobby syringe to prevent drying out or contamination. I usually do it with inks, some glues, some solvents, etc.

I read that BLO and similar oils can combust in crumpled-up rags so I know not to burn my house down. I wouldn't beusing rags though. I'd be using it on Q-tips, with small brushes, etc.

I also read that these tubs of BLO are great when fresh but get worse over time due to exposure to air when you open them. A syringe would be a better way to store and use small amounts. My syringes go up to 100-150ml. They have luer lock threads and can be screwed shut. They are made of Polypropylene.

So can BLO be stored in syringes or am I missing something? Just wanna make sure before I screw things up.

boiled linseed oil can combust in crumpled up rags because the curing process is exothermic - it makes heat. So a crumpled pile of paper or rags might insulate it enough for the heat buildup to reach the ignition point and FWOOSH! It's also an oxidation reaction, so yes, keeping it sealed up tight will negate that issue.

I can't find anything about what specific plastics you can store boiled linseed oil in, just be aware of what solvents and siccatives are used in the specific brand you're getting and make sure that they're safe for polypropylene and you'll probably be fine. I'd recommend storing them on a metal tray and inspect the plastic before use, just in case. Also UV can cause chemical changes in the boiled linseed oil, so you'll want to store them inside something light-proof anyway.

Yes, you can store them in this way.

You could also just store them in a StopLoss bag, or buy a can of finish preservative (argon gas) that you spritz into the big can of BLO.
