12 Herbal Powders to Use in Soap

Herbal powders are a convenient way to add nourishing components and label appeal to your handmade soaps!

Instead of infusing herbs (and flowers) in oil or water for soap, you can stir small amounts of the finely powdered herbs into the:

  • lye solution,
  • warmed oils,
  • or the soap batter at light trace.

Some ground floral powders, like calendula and chamomile, add a slightly speckled texture and color. Marshmallow root powder is often added for moisturizing and soothing properties.

Other herbs, like ground mint or basil leaves, may start off green, but will eventually discolor to brown, so use those sparingly. Two more to be aware of are ground lavender, as it turns gray-brown when mixed into soap batter, and powdered rose petals which darken to a brown or black color.

Why add herb powders to soap?

Herbal powders offer a variety of potential skin soothing benefits, label appeal, and some will even give your soap a soft color.

I’m often asked if the benefits of herbs and flowers remain in soap, and always like to refer to this article: “Ask the Experts – Saponification

Some herbal powders act as exfoliants, so it’s wise to keep the amounts on the low side or the soap may turn out too scratchy.
