Sanitizer - do it yourself
Inspired by the chemical DIY crafts of Comrade Meklon ( many thanks for the recipe for the PMM powder), I offer my answer to the crisis, the flu, and the greedy imperialists. Today we will collect at home the so-called Sanitizer is a means for quick disinfection. Moreover, "... in Moscow today the flu is rampant" (c).
The usual disclaimer: you do everything at your own peril and risk, do not eat clay, do not run around the room with scissors.
The average sanitizer is not very expensive, but not a penny. For a bottle of 50 ml they ask one hundred rubles, a more "wholesale" package of 250 ml costs 300 r. Let's try to do no worse, but cheaper.
So, all antiseptic gels contain 60-70% alcohol. This is what they are valuable for - they kill all life on the surface of the hands (or what else can be smeared there). The rest is perfumes / dyes, as well as thickeners. More about them.
We study the label, we see painfully familiar substances - glycerin and propylene glycol (PG). There are also vitamins, a carbomer moisturizer and other ingredients. I consider taking vitamins through the skin as stupid, so we will focus on the magnificent four - alcohol, glycerin, PG and another secret ingredient (about it later).
We begin to figure out. In the extreme case, we dilute 2 to 1 alcohol with a thickener (glycerin + PG) without adding water. If it turns out a little thick for your taste - you can replace part of the thickener with water (by the way, it will turn out even cheaper).
Alcohol (aka “antiseptic solution”, aka “aseptolin”) can be bought at 40 rubles per 100 grams. This is retail packaging, cans are much cheaper. Where to get a thickener? Oddly enough, in stores with electronic cigarettes. Soaring liquid is the same glycerin with propylene glycol. We buy the cheapest non-nicotine liquid for an electronic cigarette. The fragrance is your choice. Small retail - 100 rubles per 10 ml (robbery, I think).
Total, mixing a bottle of alcohol with 5 bubbles of liquid, we get 100 + 10 * 5 = 150 grams of sanitizer. We spent 540 rubles on this (180 r per 50 g jar), which is even more expensive than branded gel. Dead end? Not.
Firstly, by excluding propylene glycol from the prescription (by the way, some citizens are allergic to it), you can save a lot of money. We buy glycerin in a pharmacy for 10 rubles per 25 grams. And the price of a homemade sanitizer immediately drops to (40 + 10 * 2) / 3 = 20 rubles per 50 ml. If you do not want to depart from the canonical recipe, you should look in the direction of stores where components for self-production of cigarette liquids are sold. There is propylene glycol at about 70 rubles per 100 grams. We do the calculation again, given that the ratio of GHG and glycerin is approximately equal. We consider the cost of manufacturing 50 grams of sanitizer. (40 + 10 + 70/4) / 3 = 22.5 rubles. Bingo!
Finally - about my know-how. I add 5 grams of an aqueous solution of chlorhexidine (local antiseptic) per 100 grams of a homemade sanitizer. The idea is that alcohol from the hands will evaporate sooner or later, and chlorhexidine will remain on the skin for a while, giving additional protection against harmful microbes.
Save money and health!
PS Do you know what is the biggest problem in making a sanitizer at home? Find a suitable convenient and small bottle to carry what you have made with you. Can anyone advise what can be used for this?
PPS Well, I will traditionally be grateful for comments from doctors and chemists.
