How to make a Hand Sanitizer

Washing and sanitizing your hands has never been more important, whilst personal hygiene practices are top of the list in keeping yourself safe, it is not always practical to wash you hands when out and about. We have you covered with options from the beginner to the advanced DIYer.

What is a Hand Sanitizer?

A hand sanitizer is product designed to sanitize your hands and to remove/kill 99.9% of the micro-organisms. The usual base of a sanitizer will usually be denatured ethanol or isopropyl alcohol. Denatured ethanol and Isopropyl alcohol can come in different strengths, but for the purpose of hand sanitizer you want to purchase these products as the highest possible %.  You can also find alcohol-free versions available as well. 

PureNature’s Denatured Ethanol – 99.85%                   PureNature’s Isopropyl Alcohol – 99.97%

This can be diluted to make a 60% - 70% (hospital grade) solution.  Eg.  70grams isopropyl/ethanol 30grams water. Whilst this will work it will be very drying on the hands, this is where we can put our DIY skills to use and add some extra’s to make it gentler.

Thickeners and gums can be used to “gel” the formula butt this is harder to do, and we will get it to that further below.

Hand Santitizer Base

We now have an Alcohol Free hand sanitizers base to make things ultra-easy for you. Just like our other bases you can add 5% of added extra’s or use as is, you can find exact instructions on how to use and customise these on its product page.

Hand Santitizer Extra’s

There are a lot of “extra” ingredients you can pop into your hand sanitizer whether using a base or formulating from scratch to make it gentler on the hands.  Some ingredient to play with:

Glycerin, Propanediol, Vitamin E, Provitamin B5, Aloe Vera, Allantoin, Extracts, sprinkle of micafor colour.

Fragrances/Essential Oils – used for smell, yes essential oils do have antimicrobial properties but not at this diluted rate. Citrus Essential oils can be phototoxic so best to stay away from these.
