ehtyl alcohol (ethanol) can be 70% in the final recipe. sitting here looking at store bought hand sanitizer (DG brand comparable to Purell) and it's active ingredient is ethyl alcohol @ 70%. personally i prefer to make mine to be the gel thickness you find in commercial products. i have 99% isopropyl (same company in Fl you are using) and 200% ethanol non denatured. i'm waiting on an amazon order for the emulsifier/thickener which will be here thursday and i'll report back on my final result. i have all the stuff you have there.
Let me know how the thickener works out. Maybe put a link for the one you used so other can do this also? Just remember the volume per volume, the thickener may change this calculation when its added and diluted the alcohol percentage. The ethanol percentage recommended seems mixed. The CDC link I have in the description says 70%, most store bought I looked at uses 72/73%, and the WHO formula stated 80%. So I chose on the side of cation with 80% using ethanol, better to be safe then sorry. I think store bought does mostly 73% so it last longer with expiration compensating for some evaporation over a year of use. I have seen some refills of the shelves now, (not the gel) so I stopped making it since they can do it cheaper. I did it to give it away to first responders, meals on wheels and the soup kitchen. One from White House Foods in Winchester, VA, they usually make vinegar (its in a vinegar bottle) and uses 80% ethanol. Actually is the same formulas from the WHO and I like the WhiteHouse one. Another in a small spray bottle made from Liquid Filling Solutions using the same formula in the video with 75% isopropyl but they are heavy on the peroxide and it leaves a smell on the hands.
@@GadgetReviewVideos absolutely. this weekend it's all i'll be doing saturday.

Hi Steve, most of what I have reviewed notes 80% ethanol and 75% isopropyl alcohol. This includes documentation from the FDA, CDC, and WHO. It’s only confirmed as of now that these concentrations are effective against similar strains fo viruses like SARS-CoV-2. I have not seen any confirmed lab tests again COVID-19 at this time of this comment being posted. The CDC has many articles that conflict between lower alcohol levels and higher ones, but only one that mentions specifically about COVID-19 that recommends 80% ethanol and 75% isopropyl, the link is in my video description. The CDC part I’m referring to states “formulations containing 80% ethanol or 75% isopropanol, both of which are in the range of alcohol concentrations recommended by CDC, inactivate SARS-CoV-2“ I know a lot of older publications mention lower alcohol levels, but this was mainly before these new strains of viruses. I just wanted to mention this so you don’t end up making a hand rub that doesn’t work against COVID-19. Scott
@@GadgetReviewVideos ok great. that's easy enough to fix. so i just got most of my ingredients in today and fired up a test run. i used this video recipe: ruclips.net/video/z9kYGJamctQ/видео.html this is a 70% yield ISO but easy enough to fix that. this feels exactly like purell...i didn't even mix it super well and it's just a bit thick but that's because i didn't really get every single bit of the carbopol mixed with the water perfectly. thinking about heating the water a bit next attempt. but using this recipe it feels exactly like purell on the skin. waiting for my oils and coloring which should be here tomorrow and sunday. here is the small batch I made: lets make 250 ML 75 ML water .5 tblspoon carbopol (1.5 teaspoons) 175 ML ethanol .25 tblspoon glycerin (.75 teaspoons) 2-4 drops triethanolamine (tea)
If you go to my page under the about tab, you can get me email address. Send me an email, I will be more then happy to help. It will be easier then leaving comments back and forth. ruclips.net/channel/UCq4qw9Rj_AebpIpari5wx9wabout Did you try the alcohol percentage calculator I have in the description? This is from someone else, but I have checked all the math in the sheet and its correct. I found this after I did my video and compared it with my calculations and it came out good. Alcohol Content Calculator spread sheet: docs.google.com/spreadsheets/d/191D9TTHEJtSrB1OkPr1vw6ItPXFvbbl5--2rHLb9F2M/copy Using the calculator your small batch in your comment only comes up about 67.01% ethanol. I’m assuming its 100% ethanol?? Try the calculator, it will make your life easier :-) This is part of the reason why most shoot for 5% more giving that margin of error in the hydrometer, not exact measurements with kitchen utensils, and the alcohol being slightly off. For example, did you know when a ethanol container is open it will extract humidity from the air. So each time its not sealed it will pull in a little water. Also some liquids and the Glycol will get left behind on the containers. This 5% above target helps ensure its still above the needed amount to be effective. What I noticed about the video is it only came out to be 69.67% ethanol alcohol if everything is perfectly measured. The one thing I noticed in the video is at 1:19 he said 2 teaspoons of carbopol, but then later at 1:32 he said 2 tablespoons. Also he mentioned 90% ethanol or higher but uses 99%. If someone used only 90% it would be 63.99%. So unfortunately his video is miss leading. This is why I did my video trying to combat the miss-information on social media. In that video he states he making 1 liter with the formula of: 2 teaspoons is 9.86ML 1 tablespoon is 14.79ML Water 250ML Ethanol 700ML TEA 10 drops is almost 1ML (I’m adding 4 drops of food coloring) Thats a total of 975.65ML, that not 1 liter. Even if he added 25 ML to the alcohol to equal 1 liter would put it at 70.39% that is if everything is an exact measurement and nothing was left behind on the containers. This is an example of why he should have had the goal of 75% to have that error correction for under measurements. A word of caution: Adding addition things like oils or food coloring isn’t recommended. Not because it changes the v/v, but also because it could change the chemistry that might make it ineffective against viruses and bacteria. Thank you, Scott
You are correct, I did consider this. Isopropyl has a density of 0.786 g/cm3 (20 °C), and ethanol is 0.7893 g/cm3 (20 °C). Making isopropyl lighter so the hydrometer will sink a little more. This is why using the W.H.O. formula they mention in the documentation that isopropyl percentage shows up higher as 77 on the hydrometer @ 25C when they compared the ethanol batch to the isopropyl batch (page 4, under quality control, step #3). Accuracy is always as good as the testing instrument and is why I did a controlled mix of 1 part distilled water and 3 part 99%+ isopropyl mix. My hydrometer came out 2.5 over 75 reading 77.5. From this I concluded the same thing W.H.O saw, with an additional 0.5 out of calibration for my hydrometer. Even if someone doesn’t take this factor of density into consideration and your shooting for 75% reading in the hydrometer then the actually percentage content would be around 72% (+/- 1) and still be above the CDC and WHO 70% recommendation needed. Thanks for the comment, after all everyone should question what they see in the internet these days, Scott
@@GadgetReviewVideos can you share a link to that formula and post it here, i could not find it. Also when you used the hydrometer at the end the density was off due to all the ingredients in your solution. you would have to check the density of just the isopropyl alcohol to find the correct v/v%
Nefarious BAE Sorry for the late reply, I somehow didn’t see your comment until tonight. The link to the formula I mentioned is all in the description of my video. The measurement at the end is consistent with the outcome of the formula from the WHO using the same kind of hydrometer with all the ingredients that was lab tested and proven effective. I’m not trying to add or change anything to the formula like essential oils that will alter the outcome of the measurement. I’m following the WHO proven decade old documentation. The one main reason I did this video is because of all the wrong and missinfortmon on social media and even major TV network news outlets that were not correct.

Why a disclaimer. You are not telling us to make u are just showing us? Lol im pre law (defense attorney) so stuff like that erks me. But good for u saving ur butt lol
It’s all about the CYA. Some states I used to live in prevent frivolous law suits, others stated like I live in currently do protect people from frivolous law suits. I’m a small channel, in the small rare chance it gets big I don’t want to deal with some suit looking to get a small settlement because someone’s house burnt down while smoking and mixing flammable alcohol and it’s cheaper then my legal cost to fight it. I’ve had a car insurance pay out for that same reason even though the other person was a fault, they decided it was cheaper. And if hot coffee at mcdonald’s taught me anything is to CYA.
