化妆品COA报告测试要求是什么

We generally use advanced analytical techniques such as gas chromatography (GC), liquid chromatography (LC), and mass spectrometry (MS) to identify and quantify different components in cosmetics.

Our experienced technicians are skilled in the analysis of various cosmetic ingredients, including emulsifiers, preservatives, fragrances, colorants, and UV filters.

The analysis results are presented in the COA report, providing a comprehensive overview of the cosmetic composition.

We conduct tests to determine the pH value of the cosmetics, as it is an important parameter that can affect product stability and skin compatibility.

Microbiological testing is performed to assess the presence of harmful bacteria, yeast, and molds, ensuring the product's microbiological safety.

Heavy metal analysis is conducted to identify and quantify the levels of heavy metals in the cosmetics, as excessive amounts can be harmful to human health.

Skin irritation and sensitivity tests are also carried out to evaluate the potential risks of skin allergies or irritation caused by the cosmetics.

We adhere to internationally recognized standards such as ISO 227162007 for Good Manufacturing Practices (GMP) of cosmetics, the European Regulation (EC) No 1223/2009 on cosmetic products, and the US Food and Drug Administration (FDA) regulations.

For specific tests, we follow relevant industry standards, such as ISO 11930 for microbiological testing and ISO 17025 for laboratory accreditation.
