Tussah silk is 100% all natural and harvested in a way that is not cruel to the silkworms. This additive should be included at the general rate of one cotton-ball sized pinch per 2kg batch of soap. The silk should be dissolved in your hot lye solution prior to adding the lye solution to your batch.
The addition of silk will cause your soap to have a more shiny appearance, slightly increased lather, be more slippery, and have a general luxurious “silky” feeling to it.
Add a small pinch of silk (about the size of a small cotton wool ball) to the lye solution while it is very hot, and stir continuously until it dissolves. Once dissolved, continue with your batch of soap as usual.
Our silk is cruelty free which means the fibers are collected from the cocoons after the silk worms have emerged.
