Phenol Test

Phenols are common compounds found in various cosmetic formulations and their presence may pose potential health risks.

Protheragen-ING offers comprehensive cosmetic phenol testing services to ensure the safety and quality of our clients' cosmetic products. Our testing services provide accurate and reliable results to help you meet regulatory requirements and build trust with your customers.

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. Many countries have regulated phenol as a banned or restricted substance in depigmenting and whitening cosmetics.

With Protheragen-ING's phenol tests, you can:

• Ensure regulatory compliance - Many regional and international regulatory bodies set limits on the amount of phenols allowed in cosmetics. Our testing services can help you ensure compliance with these regulations.
• Protect consumer health - By identifying and quantifying phenols in cosmetics, you can ensure they are safe to use and minimize the risk of adverse effects on your customers' skin and overall health.
• Improve product quality - By monitoring phenol levels, you can identify any potential contamination or degradation issues early, allowing you to take corrective action and maintain product integrity.

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:

• Identification of specific phenolic compounds present in products.
• Quantifying phenol levels to ensure compliance with regulatory limits.
• Evaluation of potential impurities or contaminants associated with phenolic compounds.

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.
