Phenol Test

Phenol, a common chemical, is an important raw material for the production of some resins, fungicides and preservatives. It is toxic and has the greatest impact on a woman's fertility. It can lead to infertility or difficulty having children. At the same time, it can damage liver and kidney organs.

CD Formulation can provide phenol detection services, complete the accurate qualitative and quantitative determination of phenol preservatives in cosmetics, and facilitate the quality control of cosmetics production.

About the Phenol of Cosmetics

The unsaturated compounds of some ingredients in cosmetics can automatically oxidize with oxygen in the air, resulting in discoloration and taste of the products. In the process of production, use and preservation, the added nutrients will also breed and multiply microorganisms, which will pollute and deteriorate the products. Cosmetics manufacturers often add preservatives to their products to prevent spoilage. The chemical properties of phenol compounds are stable, and they can kill most Gram positive/negative bacteria, fungi and molds. Therefore, some phenol compounds can be used as mildew antifungal agents in the production of cosmetics.

Phenol Test

At present, the methods for the determination of phenol preservatives in cosmetics include high performance liquid chromatography, high performance liquid chromatography tandem mass spectrometry, gas chromatography, gas chromatography-mass spectrometry, capillary electrophoresis and so on. Gas chromatography and liquid chromatography are fast, sensitive, accurate and reliable, easy to operate, and can be used for quality supervision and management.

CD Formulation provides these detectors to help test customers' samples efficiently and quickly. The detailed steps are as follows.

1) Prepare standard reserve solutions, dilute the solution into solutions of different concentrations to obtain standard working curve solutions;

2) Weighing samples, properly processed sample solution;

3) Use the instrument detection standard working curve solution and sample solution;

4) Draw the standard curve. By comparison of residual time and standard curve, phenols in cosmetics are qualitative and quantitatively analyzed in cosmetics.

Caution

• During analysis, all solutions should be made to clarify to avoid blocking the instrument.
