In the cosmetic and personal care industry, ingredient safety and purity are non-negotiable. At NINGBO INNO PHARMCHEM CO.,LTD., we understand that consumers trust brands to provide products that are not only effective but also safe for regular use. This is particularly true for ingredients like hydrolyzed keratin, which are applied directly to the skin and hair. Rigorous testing for impurities, especially heavy metals, is therefore a cornerstone of our quality assurance process.

When you 'buy keratin powder online', it’s essential to scrutinize the product specifications for heavy metal limits. The presence of heavy metals such as Lead (Pb), Arsenic (As), Mercury (Hg), Chromium (Cr), and Cadmium (Cd) can be harmful, even in trace amounts, and their inclusion in cosmetic products is strictly regulated. For instance, our hydrolyzed keratin meets stringent standards, with limits typically set at ≤ 0.50 mg/kg for Pb, As, and Hg, ≤ 2.0 mg/kg for Cr, and ≤ 0.10 mg/kg for Cd. These low limits are indicative of a highly purified product, ensuring safety for end-users.

Understanding these specifications is vital for formulators. It reassures them that the ingredients they are using are clean and free from contaminants that could compromise product safety or regulatory compliance. Sourcing from reputable 'hydrolyzed keratin suppliers china' means working with partners who prioritize these critical purity standards.

Ingredients that undergo extensive purification and testing to minimize heavy metals will naturally command a higher price, but this investment in quality is essential for brand integrity and consumer safety. It allows brands to confidently market their products, knowing that they are using ingredients that are both effective and safe. When considering 'keratin suppliers', inquire about their heavy metal testing procedures.
