Why not just use one of these?

Question regarding what mixing utensils to use when working with chemicals like vitamin c that react with metal:

I'm rather new to DIY (made a brightening serum & moisturizer so far using heat/hold method & a broad spectrum perservative). I want to make a SAP serum but it occurred to me I cannot use metal utensils like the metal spoon and milk frother I have been using so far. What would be recommended for mixing? SAP needs to be mixed very well according to my research. Would glass stirring rods and this [plastic hand mixer](https://www.amazon.com/Fit-Fresh-Portable-Drink-Formula/dp/B000FNH01E/ref=sr_1_1?ie=UTF8&qid=1496194675&sr=8-1&keywords=small+hand+mixer be) good? Shouldn't I concerned about chemicals leaching into the plastic, though? Maybe some nylon spreaders or corning lab spatulas for scraping it out of the beaker?

 

This is the recipe I am going to use.

 


SAP serum

79.3% distilled water

10% propylene glycol

5% SAP

3% glycerin

2% green tea extract

0.5% liquid Germall Plus

0.2% sodium carbomer

<1% citric acid solution (pH adjuster)


Directions:
Heat water in double broiler, making sure water is above 158F/70C in double broiler. Add propylene glycol to distilled water in a beaker and stir until dissolved. Add glycerin, stirring until dissolved. Weigh entire phase, beaker and all and make a note of the weight. Place in double boiler and hold at 158F/70C for 20 minutes. Remove mixture from double broiler, dry it off, weigh it and note the difference. Add distilled water to equal the difference in pre and post heating weight. Let cool down to 104F/40C. Once mixture is below 104F/40C, add green tea extract and sodium carbomer, one at a time, mixing and making sure each one dissolves before adding the next. Add SAP- it is essential that you do NOT add the powders to the water at once, sticky lumps WILL form. It is best to sprinkle tiny amounts at a time, mix that, and then add more. Mix 50% citric acid and 50% warm distilled water in a separate container until it dissolves. Use a pipette to add the pH adjuster in the SAP solution. Add about 2 or 3 drops then test the pH and repeat until you have reached to 6 pH. Add preservative, mixing until dissolved.

Drink Mixer

I use one of those for my BPC. Not as good as a full immersion blender, but I keep it on my desk at work and it is good enough.

lots of people use something like this:

I used to use a cheap frother for mixing but it didn't do a great job. The frother is a little too flimsly to properly mix with heavy VG juice in my opinion. The VG stayed at the bottom and the flavorings stayed near the top.

I recently got a different mixer that is not a frother and works way, way better. I usually mix for a few seconds then let it sit in a crock pot for around 10 minutes, then mix again for a good minute or two and then just let it sit. I mix once or twice a day for a few days and it is good.

Here is the one I got http://www.amazon.com/gp/product/B000FNH01E?psc=1&redirect=true&ref_=oh_aui_detailpage_o07_s00

I love this drink mixer for on the go. Works like a charm and comes with a case that easily fits in my purse. I find it works better than a frother.

I think I've seen a drink stirrer sort of similar.

edit again: I remember seeing rubber-band plane winders when I was a kid. GIS search shows some manual ones with a hook and some motorized but not that particular one.

I use a handheld drink mixer. Fits in any type of bottle and doesn't introduce as much oxogen as a frother.

Mine came with the optional attachments that will fit into 30ml bottles.

Those mini electric drink mixers. My friend made fun of mine until she saw how evenly they mix hot cocoa powder in a cup of milk. They're also really easy to clean.
