Frequently Asked Questions (FAQ) about Natural Indigo Powder for Soap Making & Cosmetics

How much natural indigo powder do I use in cold process soap?

Use 1-3% of total oils (0.5-1.5 tsp per pound) for rich blue colour. Start with 1% for subtle tones, 2% for medium blue, and 3% for deep indigo. Always disperse in lightweight oil before adding to batter.

Does natural indigo powder bleed in soap designs?

No! Our cosmetic-grade indigo powder is bleed-resistant when properly dispersed. Pre-mix with 1:3 oil ratio and add at light trace for clean swirls. Avoid over-saturation to prevent migration in both soap and makeup.

Is natural indigo powder pH stable in cold process soap and cosmetics?

Yes! It withstands saponification pH (9-10) in soap without colour shift, maintaining true blue tones from trace through curing. In cosmetics, it's stable across pH 4.5-8.5 for eyeshadows, lip stains, and face powders.

Can natural indigo powder be used in melt-and-pour soap and makeup?

Absolutely! Use 0.5-1% directly in melted M&P base for translucent blue colour. For opaque soap or mineral makeup, disperse in glycerine first. The powder integrates smoothly without graininess in both applications.

What's the best dispersion method for natural indigo powder in soap and cosmetics?

Pre-disperse in lightweight oils (grapeseed, jojoba) at 1:3 powder-to-oil ratio for soap. For cosmetics, use glycerine or cyclomethicone dispersion. Warm gently if needed, then add at appropriate phase for clean colour integration.

Does natural indigo powder fade in sunlight for soap and makeup?

Our lightfast indigo powder maintains colour for 12+ months under normal conditions. For maximum stability in sunny Australian climates, store finished soaps and cosmetics away from direct sunlight to preserve vibrancy.
