Indigo

The Deep Blue Botanical

Indigo Powder, derived from the Indigofera tinctoria plant, has been used for centuries as a natural dye for textiles, body art, and cosmetics. This rich botanical colorant produces stunning shades of deep blue, denim, and even soft grayish hues, depending on its preparation and the pH of the soap.

In soap making, Indigo Powder creates gorgeous blues that range from soft sky tones to deep navy. It blends well with other natural colorants, allowing for unique shades and artistic effects. Indigo is also gentle on the skin, making it a favorite for those who want natural, skin-safe colorants in their handmade soaps.

For skincare, indigo is known for its calming and anti-inflammatory properties, making it a popular ingredient in soothing balms, salves, and skin treatments. Traditionally, it has been used to help reduce irritation, support skin healing, and even balance excess oil production.

Best Uses: Rich blue natural soap colorant; gentle skincare treatments for soothing irritation; herbal-infused oils for balms and salves; blending with clays and other botanicals for custom shades.
