For purchasing managers and formulators in the cosmetic industry, understanding the detailed specifications of raw materials is critical for ensuring product quality and efficacy. Keratin, a fundamental protein for hair and skin, is no exception. When sourcing Keratin powder, buyers need to focus on key metrics that indicate its suitability for their formulations. As a leading supplier and manufacturer of cosmetic ingredients, we provide insights into these essential specifications, guiding you in making informed purchasing decisions for high-purity Keratin.

The primary specification to consider when buying Keratin powder is its protein content. High-quality Keratin, such as our cosmetic-grade Keratin (CAS 68238-35-7), typically boasts a minimum protein content of 85%. This figure directly correlates with the ingredient's effectiveness in strengthening hair, improving skin texture, and providing other beneficial properties. A higher protein percentage signifies a more concentrated and potent form of the protein, essential for achieving desired results in cosmetic products like shampoos, conditioners, lotions, and creams.

Beyond protein content, other critical specifications include appearance, moisture level, ash content, and pH. Our Keratin powder presents as a light yellow powder, indicating its processed form. Low moisture content (≤8.0%) is vital for product stability and shelf life, preventing degradation or microbial growth. Similarly, controlled ash content (≤6.0%) ensures the absence of unwanted inorganic impurities. The pH range (5.5-7.5) is important for compatibility with other formulation ingredients and for maintaining the integrity of the final product. We ensure that our Keratin adheres to these stringent quality standards, making us a trusted supplier for cosmetic manufacturers.

When sourcing Keratin, buyers should also be aware of impurity levels, particularly heavy metals and microbial counts. Strict adherence to safety regulations is a hallmark of a reliable manufacturer. Our product specifications include limits for heavy metals such as Lead (Pb), Arsenic (As), and Mercury (Hg), along with microbial limits for total bacteria, coliforms, and mold & yeast. These parameters ensure the safety and suitability of our Keratin for cosmetic applications. We are committed to transparency, providing detailed Technical Data Sheets (TDS) to all our clients.
