Product Overview

What Is Bio Indigo PReR™?

Bio Indigo PReR™ is AMA Herbal's liquid natural indigo dye for denim mills and textile dyeing units. It is produced from Indigofera tinctoria using a biochemical pre-reduction process, and supplied as a stable, ready-to-use liquid for industrial indigo dyeing.

Conventional liquid indigo dyeing relies on reducing agents — typically hydrosulphite and caustic soda — to convert solid synthetic indigo into its active, soluble form. Bio Indigo PReR™ addresses this by supplying natural indigo that has already been pre-reduced through a biochemical route, without hydrogenation or electrolysis-based reduction steps.

The result is a liquid natural indigo dye that is directly compatible with existing rope dyeing lines, slasher dyeing ranges, yarn dyeing machines, and fabric dyeing units. Mills can evaluate Bio Indigo PReR™ without redesigning their dyeing infrastructure or sourcing additional machinery.

For denim mills, garment exporters, and sustainable fashion brands that need a natural indigo dye with certified sustainability credentials, Bio Indigo PReR™ offers support for GOTS Version 7.0 and ZDHC Level 3.0 requirements alongside a traceable plant-based origin from Indigofera tinctoria cultivation.

AMA Herbal produces Bio Indigo PReR™ in India and supplies it to denim mills and textile manufacturers in more than 40 markets. Interested buyers can contact AMA Herbal to request technical data, application guidance, and supply information for liquid natural indigo adoption.

Key Benefits

Designed for Industrial Textile Dyeing

Bio Indigo PReR™ is formulated to work within existing dyeing infrastructure, reduce chemical load, and provide certification documentation for sustainable denim supply chains.

01

Ready-to-Use Liquid Format

Supplied as a pre-reduced liquid natural indigo dye for direct use in existing liquid indigo dyeing systems. No on-site reduction setup or additional mixing equipment required for industrial adoption.

02

Natural Indigo Based Solution

Made from Indigofera tinctoria — a legume plant with soil-fertility benefits through nitrogen fixation. Provides a plant-based, traceable indigo source for denim mills and textile brands with natural dyeing requirements.

03

Suitable for Denim Dyeing

Compatible with rope dyeing, slasher dyeing, yarn dyeing, and fabric dyeing configurations. Designed for the indigo dyeing processes used in industrial denim and cotton textile production.

04

Supports Sustainable Textile Production

Helps reduce hydrosulphite use and eliminates caustic soda in the reduction stage. Avoids hydrogenation and electrolysis-based reduction — supporting lower-impact chemical profiles in sustainable textile dyeing programmes.

05

Simplified Handling and Logistics

No nitrogen-filled containers or airtight packing required. This simplifies transportation, warehouse handling, and supply chain management for liquid natural indigo dye adoption at industrial scale.

06

GOTS 7.0 and ZDHC Level 3.0

Supports GOTS Version 7.0 and ZDHC Level 3.0 requirements. Useful for denim mills, garment exporters, and fashion brands seeking documented compliance with major sustainable textile dyeing standards.

Comparative Analysis

Bio Indigo PReR™ vs Conventional Liquid Indigo

The differences between biochemically pre-reduced liquid natural indigo and conventional liquid indigo reflect distinct chemistry routes, sustainability profiles, and supply chain implications. This comparison is provided in practical B2B terms.

Criteria Bio Indigo PReR™ — Liquid Natural Indigo Conventional Liquid Indigo
Source Plant-based — natural indigo from Indigofera tinctoria Synthetic indigo — petrochemical-derived route
Reduction Method Biochemical pre-reduction — no hydrogenation or electrolysis on-site Hydrogenation or electrolysis-based reduction at mill or supplier level
Hydrosulphite Use Reduced — pre-reduction lowers on-site requirement Standard use of hydrosulphite as reducing agent in dye bath
Caustic Soda in Reduction Eliminated — not required in reduction stage Caustic soda (sodium hydroxide) used alongside hydrosulphite in reduction
Handling Requirements Standard — no nitrogen-filled containers or airtight packing needed May require nitrogen-filled containers and strict airtight handling conditions
Additional Machinery None required — compatible with existing liquid indigo systems Existing liquid indigo systems — similar infrastructure
GOTS 7.0 Compatibility Supported Synthetic indigo has limited compatibility with GOTS natural fibre requirements
ZDHC Level 3.0 Supported Varies by supplier — documentation availability depends on manufacturer
Plant Origin Traceability Available — traceable to Indigofera tinctoria cultivation in India Not applicable — synthetic process has no plant origin
Soil Impact Positive — Indigofera tinctoria supports nitrogen fixation in soil Not applicable — no agricultural connection

Note: This comparison is based on general product characteristics. Performance in dyeing applications depends on process conditions, substrate type, and mill-specific setup. Mills are encouraged to conduct trial evaluations. Contact AMA Herbal to request technical discussion and sampling.
