Why Choose Phenol Tests?

Phenol has a whitening effect on the skin, but many countries have banned or restricted the use of phenol in blemish-removing and whitening cosmetics.

Phenols are widely used as preservatives, antioxidants and flavorings in cosmetics. However, excessive phenols can cause skin irritation, allergic reactions, and even systemic toxicity.

Comprehensive Analysis

Protheragen-ING's laboratory is equipped with state-of-the-art equipment and staffed by experienced cosmetic testing experts. We utilize advanced analytical techniques to detect and quantify various phenols in your cosmetic samples.

Our comprehensive analysis covers:

Test Procedure

  1. To create a standard working curve solution, prepare a standard stock solution and dilute it to various concentrations.
  2. Weigh the sample and treat the sample solution appropriately.
  3. Test the sample solution and the standard working curve solution using the instrument.
  4. Make a standard curve plot. Analyze the phenolics in cosmetics both quantitatively and qualitatively by contrasting the residual time with the reference curve.

Test Methods

Protheragen-ING mainly uses gas chromatography-mass spectrometry (GC-MS) for the qualitative and quantitative determination of phenolics in cosmetics.

The samples were extracted by methanol, and the purified extracts were separated by a capillary column and detected by selected ion monitoring (SIM) scan mode. The method is simple, rapid and sensitive, and can effectively eliminate the interference of cosmetic matrix.

In addition, we can also use spectrophotometry, chromatography and capillary electrophoresis for the determination.

Customized Test Plans

Protheragen-ING can develop customized test plans to fit your products. Whether you need a one-time analysis or regular monitoring, we can design a test plan that meets your needs.
