Our Indigotin powder is sourced from high-quality, organic Indigofera tinctoria. We choose this source because it ensures the purity and sustainability of the product, providing a natural alternative to synthetic dyes. The raw material is carefully processed through a traditional extraction method to maintain the integrity of the pigment, resulting in a fine, high-quality powder.
The most popular product specifications include various grades of powder, ranging from light to dark blue. The powder typically has a smooth, fine texture, and its scent is subtle, with no strong odor. The taste is generally neutral, aligning with its natural origin.
In terms of market applications, our Indigotin powder is primarily used in textile dyeing, natural cosmetics, and health products. Recommended usage in textiles is around 5-10% depending on the desired intensity of color. In cosmetics, the powder is added in smaller quantities for color and skin benefits.
Customers choose our product for its high purity, sustainable sourcing, and effective results. Our commitment to quality processing ensures that our Indigotin powder provides consistent, vibrant color, and better performance compared to competitors. Moreover, our clients have consistently provided positive feedback regarding both the quality and versatility of the product, making it a trusted choice for manufacturers.
