I thought that the water has to be
.99% alcohol, not .5%, so I am nervous to use it.

0.05% BENZYL ALCOHOL IS ENOUGH TO DISSOLVE THE BACTERIA THAT LIVES ON EVERY LIVING SURFACE INCLUDING YOUR SKIN
WITH SLIGHTLY LESS ALCOHOL THE PEPTIDE COMPOUNDS IT IS DESIGNED TO BE USED WITH LAST A LITTLE BIT LONGER WHEN MIXED

Great product, good value, speedy delivery

Does what it says on the tin

Good quality and easy to use.
