Choosing the Right Packaging Barrier Test for Cosmetics

Packaging plays a crucial role in preserving the quality and safety of cosmetic products. One of the most important aspects of packaging is its ability to act as a barrier against moisture and oxygen, which can degrade products and reduce their shelf life.

 
Moisture and Oxygen Barriers: Why They Matter

Moisture and oxygen can cause a variety of problems in cosmetic products, including:

ž Product degradation: Exposure to moisture can lead to spoilage, discoloration, and loss of efficacy. Oxygen can cause oxidation, leading to rancidity and color changes.

ž Microbial growth: Moisture and oxygen create favorable conditions for microbial growth, which can compromise product safety.

ž Shelf life reduction: Effective moisture and oxygen barriers help extend the shelf life of cosmetic products, reducing waste and improving product longevity.

Common Test Methods

To evaluate the moisture and oxygen barrier properties of cosmetic packaging, manufacturers employ various testing methods, including:

ž Moisture Vapor Transmission Rate (MVTR): Measures the rate at which water vapor passes through the packaging material.

ž Oxygen Transmission Rate (OTR): Measures the rate at which oxygen passes through the packaging material.

ž Water Vapor Permeability (WVP): Measures the ease with which water vapor can pass through a material.

ž Oxygen Permeability (OP): Measures the ease with which oxygen can pass through a material.

These tests are typically conducted using specialized equipment under controlled conditions to simulate real-world storage and use.

Factors to Consider

When selecting and conducting packaging barrier testing instrument, manufacturers should consider the following factors:

ž Test conditions: Temperature, humidity, and pressure can influence test results.

ž Accuracy and precision: Choose test methods and instrument that provide accurate and precise measurements.

ž Regulatory compliance: Adhere to relevant industry standards and regulations.

Labthink C403H and C406H Oxygen /Water Vapor Transmission Rate Test Systems are based on the testing principle of Coulometric oxygen sensor and infrared water vapor sensor. They are equipped with high-precision temperature and humidity sensor, to monitor and record temperature and humidity changes in real time, ensuring stable test conditions. The instruments have high test repeatability of 0.01 cc / (m2·day), provide accurate and precise measurements. They are designed according to ASTM D3985, ASTM F1249, ISO 15106-2 and other relevant standards. In addition, the instruments can test OTR and WVTR, and with high quality sensors, have Longer service life.

By employing appropriate testing methods and adhering to industry standards, cosmetics manufacturers can ensure the safety, quality, and longevity of their products. Effective packaging barriers are essential for protecting cosmetic formulations from moisture and oxygen, preserving their integrity, and maintaining consumer confidence.

As the demand for functional packaging materials grows, testing methods are evolving to ensure a more comprehensive evaluation of packaging films. Labthink encourages collaboration with packaging industry companies for quality control! Visit the website www.labthink.com to learn more!
