Our asbestos analysis by PLM service provides reliable identification and quantification of asbestos fibers in a wide range of materials. We perform testing in accordance with ISO 22262-1:2012, a globally recognized method for asbestos identification using polarized light microscopy.
Asbestos contamination remains a serious safety and regulatory concern. For this reason, accurate laboratory testing is critical for cosmetic manufacturers, raw material suppliers, and industrial product companies. This is especially true for cosmetic talc-based products, where asbestos contamination has resulted in regulatory enforcement actions and recalls.
Polarized Light Microscopy is a well-established analytical technique that identifies asbestos minerals based on optical properties such as birefringence, refractive index, and crystal structure. Using this method, laboratories can distinguish asbestos fibers from non-asbestos mineral look-alikes that may appear similar under basic microscopy.
This testing approach detects all regulated asbestos types, including:
Chrysotile
Amosite
Crocidolite
Tremolite
Anthophyllite
Actinolite
PLM asbestos testing is commonly applied to:
Cosmetic talc and talc-containing cosmetic products
Raw cosmetic ingredients and fillers
Powders, pigments, and mineral additives
Building materials and insulation
Industrial and consumer goods
Because asbestos regulations apply across multiple industries, PLM analysis supports both product safety assessments and regulatory compliance programs.
ISO 22262-1:2012 establishes standardized procedures for identifying asbestos in bulk materials. As a result, test results are repeatable, defensible, and suitable for regulatory submissions, supplier qualification, and quality investigations.
Pentyl Labs provides clear, defensible asbestos testing using PLM with practical turnaround times. We support manufacturers and brand owners with results that align with regulatory expectations and industry best practices.
