Diethanolamine content testing measures the concentration of diethanolamine (DEA, CAS No. 111-42-2) in cosmetic, personal care, and cleaning product formulations. Pentyl Labs performs this analysis using gas chromatography with flame ionization detection (GC-FID) to provide accurate and reproducible results for regulatory and safety evaluations.
Diethanolamine is used in some formulations as a surfactant, emulsifier, or pH-adjusting agent. However, regulatory agencies closely monitor DEA due to potential health concerns and its classification under California Proposition 65. Because of this, manufacturers often require analytical data to understand DEA levels and assess compliance risk.
Pentyl Labs’ diethanolamine content testing separates DEA from other formulation components and quantifies it using GC-FID. This technique offers strong sensitivity and reliability for amine compounds, even in complex matrices that contain surfactants, fragrances, or preservatives.
Manufacturers commonly request DEA testing during formulation development, reformulation, or prior to product launch. Testing also supports supplier qualification, batch verification, and investigations related to raw material changes. Early detection helps brands manage risk before products enter the California market.
DEA content testing plays an important role in California Proposition 65 compliance programs. Products containing DEA above certain exposure thresholds may require additional evaluation, reformulation, or warning considerations. Analytical results from GC-FID testing support internal risk assessments and regulatory decision-making.
Testing may be performed on raw materials, bulk formulations, or finished products. This flexibility allows manufacturers to evaluate DEA content at multiple stages of the product lifecycle and maintain consistent formulation control.
This service is often included within broader Chemical Analysis Services and Proposition 65 Compliance Services. Guidance from the California Office of Environmental Health Hazard Assessment defines the chemical listings and compliance framework used during these evaluations.
Overall, diethanolamine content testing provides clear, defensible analytical data that supports regulatory compliance, product safety, and informed formulation decisions.
