Heavy Metals Analysis (ISO 21392)
Heavy metals analysis evaluates trace levels of metal impurities in finished products and raw materials. This testing helps manufacturers confirm product safety, maintain quality, and meet regulatory expectations. At Pentyl Labs, we perform this testing in alignment with ISO 21392, which provides guidance for assessing unavoidable trace metals in cosmetic and consumer products.
In many cases, metals enter products through raw materials, pigments, or manufacturing equipment. Therefore, testing plays a key role in identifying potential risks early. As a result, manufacturers gain confidence that metal levels remain within acceptable limits.
Why Trace Metal Testing Is Important
Trace metal testing helps determine whether metal impurities could pose a safety or compliance concern. Common elements include lead, arsenic, cadmium, mercury, and other metals of toxicological interest.
For this reason, manufacturers use trace metal testing to support:
-
Product safety reviews
-
Raw material qualification
-
Supplier verification
-
Quality control programs
-
Regulatory and retailer documentation
By identifying impurities early, companies can reduce compliance risk and avoid costly reformulation.
ISO 21392 and Product Safety
ISO 21392 focuses on evaluating trace metal impurities rather than intentionally added ingredients. Because low-level metal content may be unavoidable, the standard provides a practical framework for safety evaluation.
As part of this approach, results are reviewed alongside toxicological assessments and regulatory guidance. In turn, this helps determine whether detected levels present a concern.
Where Trace Element Testing Is Applied
Trace element testing applies to many product types. For example, it supports testing of:
-
Finished cosmetic and personal care products
-
Pigments and color additives
-
Raw materials and formulation bases
-
Consumer and household products
In addition, manufacturers often use this testing to support regional cosmetic regulations and broader product safety programs.
