Industrial Applications

Leather Industry

• Used in tanning and retanning processes.

• Produces leather that is soft, durable, lightfast, and resistant to elongation.

• Enhances brightness and maintains a fine, tight grain.

• Recommended dosage:

  • Bovine leather: 2–10% (on shaved weight)

  • Goat and calf skins: 2–3%

  • Deep blacks: 20% WOF + 1% ferrous sulfate mordant

Textiles

• Improves light and wash fastness of dyes.

• Works better with cellulose fibers than protein fibers.

• Creates deep shades of black when combined with iron salts.

Paper Industry

• Serves as a natural tannin source in paper processing.

Pharmaceuticals

• Used in the production of gallic acid, a precursor for various medications.

Food & Beverage

• Contributes to tannic acid production, applied in brewing beer and wine.

Agriculture

• Functions as an organic fertilizer, enriching soil and improving water retention.

• Suitable for organic farming practices.

Cosmetics

• Valued for antioxidant properties, with potential anti-inflammatory benefits.

Analytical Data

• Tannin Content: 56% ±4 (SGS Peru AOAC method)

• Active Matter: Minimum 93.5%

• Moisture Content: 6–8%

• pH (20% aqueous solution): 4.0–5.0

• Insoluble Matter: 5–15%

• Grading: 92% in MESH 100

Storage & Packaging

• Shelf life: Over 2 years in sealed, original packaging under cool, dry conditions.

• Packaging: 25 kg laminated polypropylene bags.

Sustainability & Social Impact

• Harvested sustainably without damaging trees.

• Provides significant income for rural Peruvian communities.

• Cultivated partly as erosion control, supporting biodiversity.

• Represents a biodegradable, eco-friendly alternative to synthetic tanning agents.

Advantages & Considerations

Advantages

• High tannin yield, low iron content.

• Produces bright, lightfast leather.

• Eco-friendly and biodegradable.

• Supports local communities and fair trade.

• Versatile across industries.

Considerations

• Sensitive to iron salts (risk of staining).

• Performs better on cellulose fibers than protein fibers.

• Requires careful pH management in certain processes.

In essence, Tara Powder is not just a tanning agent—it’s a multi-industry natural extract that combines performance, sustainability, and social responsibility.

1. Leather Industry

• Suitability: Highly suitable for tanning and retanning. Produces bright, lightfast, soft, and durable leather.

• Dosage:

  • Bovine upper and upholstery leathers: 2–10% (on shaved weight).

  • Goat skins and calf: 2–3%.

  • Deep black tones: 20% WOF + 1% ferrous sulfate mordant.

• Notes: Sensitive to iron salts; advisable to add a small amount of sequestering agent to prevent stains.

2. Textile Industry

• Suitability: Works better with cellulose fibers than protein fibers. Enhances light and wash fastness of dyes.

• Dosage:

  • General fastness improvement: 10% WOF.

  • Deep black shades: 20% WOF + iron mordant.

• Notes: Not recommended for cold dyeing; effective in hot dyeing processes.

3. Paper Industry

• Suitability: Used as a natural tannin source in paper processing.

• Dosage: Applied in variable proportions depending on desired paper strength and finish.

• Notes: Provides eco-friendly alternatives to synthetic additives.

4. Food & Beverage

• Suitability: Contributes to tannic acid production, used in brewing beer and wine.

• Dosage: Industrial extraction processes vary; typically standardized to yield tannic acid rather than direct powder application.

• Notes: Not used directly as a food additive but as a precursor in tannic acid production.

5. Pharmaceuticals

• Suitability: Source of gallic acid, an important compound in medications.

• Dosage: Applied in extraction processes; not used directly in raw form.

• Notes: Gallic acid derived from Tara is valued for antioxidant and anti-inflammatory properties.

6. Agriculture

• Suitability: Functions as an organic fertilizer, enriching soil and improving water retention.

• Dosage: Application rates vary depending on crop type and soil condition; typically blended into organic fertilizer formulations.

• Notes: Suitable for organic farming practices; replaces synthetic chemicals.

7. Cosmetics

• Suitability: Used for its antioxidant properties in skincare and haircare formulations.

• Dosage: Incorporated in extract form; concentration depends on product type.

• Notes: Provides natural, eco-friendly alternatives to synthetic antioxidants.
