To alleviate the global shortage of hand sanitizers, the World Health Organization (WHO) created guidelines and formulations for handrubs (WHO handrub). So, we’re producing our own! And what better starting point, than with the WHO recommended handrub formulation.
The WHO’s forumulation is for 10-liter batches and is volume-based. We adapted the WHO handrub formula for small batch testing using corresponding weight measurements.
If we establish a good base formula for handrubs, it paves the way for the addition of other ingredients. For example: emollients, humectants, and essential oils. We can also make larger batches.
