I was reading a post on a FB group about using vinegar as lye water and it struck me as counterintuitive - wouldn't the vinegar neutralize the lye?
It would indeed, so you account for that in the calculation.
How much lye will the water replacement neutralize + lye amount I need for my oils = total lye amount.
It's similar to using the more lye when you add citric acid to create sodium citrate, but more so. Of course, the reaction with vinegar would be very strong. What would the purpose be?
And this is why we tell people to stay away from facebook groups. Vinegar will neutralize lye and its not alkaline, its acidic. Whoever is planning this soap doesn't seem to understand basic chemistry.
Unless their rhubarb is suspended in vinegar or something, I don't see why it would be needed - as you say, if it needs the alkaline environment then just add it to the lye water. Unless............could it be to avoid it reacting with the lye itself? Sodium Acetate (the result of lye and vinegar) has a pH of 11 at a 1% solution. So you get your alkaline environment with no active lye.
That is then next to impossible to manage when making soap as the colour will always have to come in to contact with active lye unless you use it in HP.
I left that group when I read that. I just don't have the time or the patience anymore to deal with those folks.
who much % of the lye ?It would indeed, so you account for that in the calculation.
