Weaker concentrations are noticeably considerably less productive mainly because a lot less alcohol will come into contact with germs.
Mainly because percent solutions may be expressed in 3 various ways, it really is crucial that the type of percent solution be explicitly mentioned. If this information and facts just isn't offered, the end consumer is left to "guess" whether or not w/v %, w/w %, or v/v % was employed.
