I don't think the fibers would work well in mp since it won't dissolve. The heat of the lye solution is what dissolves the silk fibers. I think it would most likely just clump up in mp. I don't have any experience adding liquid silk to soap of any kind, but maybe someone here has and can advise.i love the idea of having silk in soaps but can we add it to mp soaps. if so which work best. the fibers or liquid silk
The liquid silk is perfect for water based products such as lotion and emulsified scrubs and small amounts can also be added to melt and pour soap. Tussah silk fibers can be dissolved in your lye solution and added to cold process soap.
