What are the peculiarities of bathing in salt water? This book I just read suggested that it was possible to do it in the morning, but not at night- is it the temperature of the water that makes the difference? What was going on?

Okay, 'Sea soap'... but why?

With most soap it would not be possible to build a lather with in sea water. The reason is the common-ion effect. Traditional soap is a sodium salt; it has a ionic "head" and organic "tail". The ionic head is sodium.
The problem is that sea-water also contains sodium. Because water (at any temperature) can only take a certain amount of sodium, it means that the amount of sodium (soap) that sea water can dissolve is already limited. Therefore the soap does not dissolve and hence will not lather.
There are certain soaps that can dissolve in sea water but they are not really soaps in the traditional sense.
Yes, the temperature has an effect. If you heat the sea-water long enough then it will dissolve more of the soap and lather.

Not too sure but I washed my hair in salt water when sailing and rinsed in fresh water. It washed it OK but there was very little lather
