I mean, if hard tap water has minerals in it, and sea water also has lots of minerals in it (even more) - how come so many people get DOS from tap water and those who make soap with sea water (usually) don't? Maybe I'm missing on something and there's some crucial difference between the two, so one of them just works while the other doesn't.
A quick Google search gives this result: 'According to scientific analysis, seawater contains a minimum of 78 different minerals, from the most commonly found, such as magnesium and calcium, to trace elements such as gold and silver in very low quantities.' Another source states around 85 different minerals.
Maybe it's a question of finding the right additives (chelators/antioxidants/conservatives) to prevent DOS? Anyway, I thought it would spark an interesting discussion. And I'm curious what KiwiMoose concludes regarding her batch.
P.S.: The wood grain combined with the custom impression gives the soap an unique rustic look!
