Himalayan Rhubarb Root Powder MMO is an underwhelming yellow brown powder that makes a crazy good red colour when in a caustic environment such as soap - just have a look at the transformation in the photo!

Himalayan Rhubarb Root Powder works best if you infuse the powder in liquid oil.  5gm in 500gm oil is a good start point, but have a play and see what works for you.  Add your infused oil as a component of your recipe.   When you add your caustic component you will see the fabulous change in the colour.
