Why Choose MHRB in Powder Form?

The inner root bark (cambium) of Mimosa hostilis contains the highest concentration of condensed tannins, catechins, and natural flavonoids found in the plant. Choosing the pre-milled powder format offers distinct benefits over shredded or whole bark:

• Instant Pigment Saturation: The micro-milled texture maximizes surface area, allowing natural tannins and red-purple colorants to dissolve into hot water baths in minutes rather than hours.

• 100% Inner Bark Cambium: Stripped of the inactive outer grey cork and woody core before pulverisation—ensuring pure, unadulterated botanical pigment with zero wood fillers.

• Seamless Blending: Mixes smoothly into natural cold-process soap recipes, clay face masks, and custom botanical pigments without leaving harsh, abrasive particles.

• Consistent Batch Strength: Homogenised powder ensures every spoonful delivers identical pigment and tannin density from the top of the pouch to the bottom.

Best Handling & Extraction Practices

• Minimize Inhalation: Because the powder is exceptionally fine, handle it in a draft-free space and avoid creating airborne dust clouds when scooping.

• Slurry First: Mix your weighed powder into a small paste with warm water before pouring it into your main bath to prevent floating dry pockets.

• Clear Dye Baths: If you require sediment-free fabric, strain your steeped dye bath through a fine cotton nut-milk bag or multi-ply cheesecloth before submerging your wet textiles.

Buyers are solely responsible for adhering to their country's legal requirements.

Frequently Asked Questions (FAQ)

Does MHRB powder expire?

When stored in its original, sealed aluminium pouch in a cool, dry place away from direct sunlight, the powder retains its full pigment potency and tannin strength for 24 to 36 months.

What is the difference between Brazilian and Mexican MHRB powder?

Mexican Tepezcohuite powder typically leans toward warmer ruby, brick-red, and terracotta undertones, whereas Brazilian Jurema Preta powder yields cooler, deeper plum, violet, and dark brown tones. Both provide very high tannin concentrations.

Do I need a mordant when dyeing with MHRB powder?

Because of its naturally high tannin content, MHRB acts as a substantive dye on animal protein fibres (wool, silk) without a mordant. For cellulose plant fibres (cotton, linen), using an alum mordant or an iron modifier significantly deepens colour fastness and shifts the tone.
