Antibiotics Test

Protheragen-ING understands the importance of consumer safety and the need for rigorous testing in the cosmetics industry. That's why we offer comprehensive antibiotic testing services for cosmetics to ensure that the products you develop or sell meet the highest standards of quality, safety and compliance.

The Importance of Antibiotic Test in Cosmetics

Antibiotics are commonly used to treat bacterial infections. However, their presence in cosmetics can pose potential health risks and can lead to the development of antibiotic resistance. To protect consumers and maintain product integrity, it is critical to screen cosmetics for the presence of antibiotics.

Our testing procedures follow internationally recognized standards to provide accurate and reliable results.

Below is an overview of our testing process:

1. Sample collection and preparation

Our experienced technicians will guide you through the sample collection process. We ensure that samples are collected in a manner that minimizes the risk of contamination and maintains sample integrity.

2. Antibiotic Analysis

We use advanced analytical techniques to screen samples for a variety of antibiotics commonly used in the cosmetics industry. Our methods are designed to detect antibiotics at trace levels, ensuring that even the smallest amounts can be identified.

3. Compliance Assessment

Once the analysis is complete, our experts evaluate the results against applicable regulatory guidelines and restrictions. We provide you with a comprehensive report detailing the presence of antibiotics in your cosmetic products.

4. Consultation and Recommendations

Our knowledgeable team of professionals can discuss test results and provide guidance on any necessary actions. We can provide advice on formulation adjustments or alternative ingredients to help you bring your products into compliance with regulatory requirements.

Antibiotic Testing Platforms

Protheragen-ING has a variety of test methods available to detect the presence of antibiotics in cosmetics. Different test methods may be suitable for different types of antibiotics and have different levels of sensitivity and specificity.

Below are some of our commonly used techniques:

Liquid Chromatography-Mass Spectrometry (LC-MS)

LC-MS is a highly sensitive and selective method for the detection of antibiotics, combining the separation power of liquid chromatography with the identification power of mass spectrometry. LC-MS can detect and quantify a wide range of antibiotics with high precision.

High-Performance Liquid Chromatography (HPLC)

HPLC uses a high-pressure pump and stationary phase to separate the components of a sample, then detects and quantifies the antibiotic using an ultraviolet (UV) or fluorescence detector.

Enzyme-Linked Immunosorbent Assay (ELISA)

ELISA is an immunological method for the detection of antibiotics that involves the use of specific antibodies that bind to the target antibiotic. The presence of the antibiotic is measured by the reaction between the antibody and the antibiotic producing a color change or fluorescent signal.

Polymerase Chain Reaction (PCR)

PCR is a molecular biology technique that can be used to detect the presence of antibiotic-resistance genes, thus indicating whether antibiotics have been used in cosmetics.

PCR amplifies specific DNA sequences of resistance genes so that they can be detected and identified.

Thin Layer Chromatography (TLC)

TLC is a simple and cost-effective method for the initial screening of antibiotics and involves the separation of components of a sample using a thin layer of adsorbent material. The separated components can be visualized under UV light or using specific chemical reagents.
