Tannic Acid

Tannic acid is a polyphenolic compound and a widely available tannin in the commercial market. It. doesn’t contain any carboxyl group. However, it is considered a weak acid due to multiple phenolic hydroxyls.

It is derived from Galla Chinensis. It is highly soluble in water and certified non-hazardous.

General Information

How We Manufacture Tannic Acid

We produce tannic acid using a stringent process that ensures uniformity, purity, and stability. High-grade gallnuts, majorly Turkish oak, of high tannin content serve as the raw material. Their tannin content guarantees consistent polyphenol extraction, offering active ingredients for the major formulation advantages.

The powdered and dried gallnuts are dissolved using hot water under controlled pressure. The application of heat and pressure facilitates the erosion of plant materials, resulting in the release of tannins. The solution is subsequently filtered to remove impurities and leave a cleaner extract behind.

The final process is drying and concentrating the purified extract into powder. Spray- or vacuum-drying is applied to provide stability, consistency, and shelf-life improvement.

Key Benefits & Functions

Tannic acid supports your formulations by increasing their stability, protection, and efficacy.

• Astringent: Tannic acid interacts with proteins on the skin surface, producing a mild tightening sensation. This minimizes the appearance of pores and restore balance to excess oil, offering better general skin texture in products.
• Antioxidant: As a strong antioxidant, tannic acid acts against free radicals formed due to environmental aggressors. Such defense mechanism decreases oxidative stress and decelerates visible signs of premature aging.
• Soothing and Protective: Tannic acid forms a thin protective layer on skin’s surface. This layer calms redness, reduces redness, and relaxes inflammation, enabling the formulations to become more suitable for sensitive applications.
• Antimicrobial: Due to its antimicrobial functionality, tannic acid naturally slows down bacteria and fungi growth. For this purpose, it is useful in keeping formulations clean, increasing product stability, and contributing to preservation systems.

Safety and Formulation Considerations

When formulating with tannic acid, precautionary measures must be in place to ensure safety. Usage level is recommended between 0.05% and 0.5%. This proportion brings benefits without producing severe astringency or irritation.

Tannic acid occasionally dehydrates dry or sensitive skin. To avoid such an effect, combine it with moisturizers or emollient ingredients. Such blending keeps the skin hydrated and increases skin tolerance in your products.

Applying these guidelines to usage keeps safety and performance in balance. Stable formulations are guaranteed by proper dosage and suitable complementary ingredients. Your end products then remain stable, efficient and balanced.

Compatibility with other Cosmetic Ingredients

Tannic acid is compatible with other cosmetic ingredients when properly managed. It is soluble in alcohol and water, thus making it simple to blend. It is therefore ideal for toners, lotions, and other water systems.

Care should be taken regarding pH stability. Tannic acid works best between a pH of 3.5 and 7.0. Outside this range, the product degrades very rapidly, and overall product performance is lowered.

It also sensitive to iron and heavy metals. The reactions result in darkening and instability. To prevent this, employ chelating agents and non-metal equipment.

Stability & Storage

Storage in good condition preserves tannic acid quality and consistency. Store in a cool, dry, and dark location. Clumping and reduced stability can result from exposure to heat, light, or moisture.

Use well-sealed containers to avoid moisture pick-up. Proper packaging plays a key role in long-term consistency. Tight sealing help maintain particle size homogeneity and ensures quality of ingredients in each batch.

Under appropriate care, tannic acid is stable for long periods of time. Proper precautions guarantee performance and consistency.
