Freeze-Thaw Stability Testing
Overview
Freeze-thaw testing is part of stability testing that allows you to determine if your formula remains stable under a variety of conditions. This type of testing puts your samples through a series of extreme, rapid temperature changes that you may encounter during normal shipping and handling. Freeze-thaw stability testing is highly recommended, especially for liquid cosmetics. These products can undergo phase separation, which can have a negative impact on the intended function. It is common to encounter extreme temperature conditions, such as freezing or overheating, during the transportation of cosmetics. Therefore, cosmetic products must be able to withstand a certain degree of temperature change during transportation.
Specific Services We Offer
- Freeze-thaw cycles
We subject your product to a series of controlled freeze-thaw cycles to replicate real-world conditions. This testing helps assess product stability, structural integrity, and sensitivity to changes in physical properties such as viscosity, texture, and appearance.
- Physical and Chemical Analysis
We perform extensive physical and chemical analysis on samples before and after freeze-thaw cycles. This analysis includes measurements of pH, viscosity, color, odor, solubility, uniformity of content, and any other parameters relevant to your product.
- Stability assessment
We assess the stability of your product by regularly monitoring its physical and chemical properties during freeze-thaw cycles. This assessment provides valuable insight into the product's ability to withstand temperature fluctuations and maintain its quality over time.
- Packaging Assessment
We assess the impact of freeze-thaw cycles on the integrity of your product's packaging. This assessment helps identify potential problems such as leakage, deformation, or degradation due to temperature changes, ensuring that the packaging remains strong and effective.
Testing Procedures
The freeze-thaw test is performed by exposing the product to freezing temperatures (~-10°C) for 24 hours and then allowing it to thaw at room temperature for 24 hours. The samples are then placed at a higher temperature (~45°C) for 24 hours and then again at room temperature for 24 hours. The samples are analyzed to see if there are any significant changes. This completes one cycle. If no significant changes are observed after three cycles of freeze-thaw testing, you can be confident that your product is stable enough for shipping.
Further Service
- Accelerated freeze-thaw testing: We can accelerate freeze-thaw cycles to simulate longer-term storage and shipping conditions in a shorter test time. This helps you evaluate product stability under more extreme conditions and predict long-term performance.
- Customized test protocols: We understand that different products may have unique freeze-thaw requirements. Our experienced team can work with you to develop customized test protocols to address your product's specific needs and challenges.
