Auxillaries are products that assist in the dyeing process. In acid dyeing, acid is a required auxillary, but other auxillaries such as salt are optional. Using 10% solutions makes measuring the auxillaries for your dyeing projects quick and convenient. The solutions keep for several months, so you can mix them up ahead of time and have them ready to use when you need them.
