Thank you all for your reply!
@Raychemist I do not mention all of the ingredients, but I do use a preservative. The viscosity that I’m lookin for is 1500-1800.
@ketchito noted!
@chemicalmatt confusing but good.. i learn so many things in this discussion. So it is best to mix SCI last. But is it ok tho to mix SCI with a little bit of water like @Raychemist suggested? Since you said SCI doesnt like water?
