Chemical analysis of cosmetic products is a critical step to ensure the safety, quality and accuracy of label information. These analyzes are performed to verify the content of cosmetic products, detect potential contaminants or toxic substances, evaluate the stability of the formulation and provide a safe product to the consumer.

An overview of some basic chemical analyzes in cosmetic products:

pH Measurement: It is a test to determine whether the product is acidic or basic. It is important for the safety of the product to be compatible with the pH balance of the skin.

Viscosity Measurement: It is done to determine the consistency and fluidity of the product.

Microbial Analysis: Performed to check for any bacterial, yeast or mold contamination in the product.

Heavy Metal Analysis: It is done to detect the presence of potentially harmful heavy metals such as lead, mercury, cadmium in the product.

Conservative Efficacy: To test the effectiveness of preservatives used to prevent microbial growth during the shelf life of the product.

Active Ingredient Concentration: Especially in products containing active ingredients (eg AHAs, vitamins, UV filters), it is done to verify whether the concentration of these ingredients is compatible with the label information.

Stability Tests: These are the tests performed to check whether the physical, chemical and microbiological properties of the product remain constant over a certain period of time.

Sensor Analysis: Evaluation of the sensory properties of the product such as color, smell, texture.

Solvent Residue Analysis: To determine whether solvents used during production remain in the product.

These analyzes are usually performed using gas chromatography (GC), liquid chromatography (LC), spectrophotometry, microscopy, and many other laboratory techniques.

Chemical analyzes in cosmetic products ensure that the products are presented to consumers in a safe manner and in accordance with the label information. However, expertise and appropriate laboratory equipment are needed to carry out these analyzes comprehensively and accurately.
