When is Stability testing required?
Stability testing is a crucial step in the development of any cosmetic product, as it ensures that the product maintains its quality and effectiveness over time. It is not only necessary for new prototypes, but also for various other scenarios where changes are made to the formulation, raw materials, manufacturing process, or packaging. In each of these scenarios, cosmetic chemists and manufacturers must conduct appropriate stability tests under specific conditions to ensure that the product meets the required quality standards and has an adequate shelf life.
Whenever cosmetic chemists develop a new formulation, they must perform a stability test to assess its shelf life and determine the appropriate conditions for storage. Stability testing ensures that the cosmetic product remains stable and does not undergo any unacceptable changes over time. For example, the European Union’s Cosmetics Regulation (1223/2009/EC) requires cosmetic manufacturers to perform stability testing on new formulations to ensure the safety and quality of their products.
New raw materials:
Whenever a manufacturer changes a raw material in a cosmetic formulation, it is important to perform a stability test to determine if the change affects the stability and safety of the product. Stability testing also ensures that the cosmetic product remains safe and effective throughout its shelf life. ISO 16128 provides guidelines for cosmetic formulation development, and it recommends that stability testing be performed on any new raw materials to ensure that they do not negatively impact the product quality.
New manufacturing procedure:
Manufacturers are always looking for ways to improve the efficiency of their production processes, but any changes in the manufacturing procedure can impact the stability of the cosmetic product. Therefore, it is essential to perform a stability test whenever a new manufacturing procedure is introduced. The International Organization for Standardization (ISO) has established guidelines for stability testing, such as ISO/TR 18811:2018, to ensure that cosmetic products remain safe and effective throughout their shelf life.
Whenever a cosmetic product is packaged in a new container, it is essential to perform a stability test to ensure that the packaging does not negatively impact the product stability. Packaging can affect the chemical and physical properties of a cosmetic product, and stability testing helps identify any changes that may occur. The Cosmetic Products (Safety) Regulations 2008 in the UK requires manufacturers to perform stability testing on new packaging to ensure that it does not affect the product quality.
How do you stability test a cosmetic?
Step 1: Preparation
Before conducting a stability test, cosmetic chemists need to prepare their formulations, including selecting raw materials and determining the desired shelf life. They also need to ensure that the samples have the correct pH, viscosity, and other parameters to meet the product’s functionality and aesthetics requirements. Initial values are taken as reference.
Step 2: Sampling
The next step involves creating samples of the cosmetic product in question. The number of samples needed may vary depending on the product’s formulation, but typically, it is recommended to create at least three identical samples, which will be used in three different storage conditions.
Step 3: Testing in various environmental conditions
The samples are then placed unde stressful temperature conditions, to determine how the product holds up over time. This process usually lasts for weeks or months, with checkpoints at different intervals to check the samples’ stability. To replicate natural conditions, the temperature used typically mimics air-freight (5.C Fridge) and sea-freight (45.C Incubator).
Step 4: Physical and chemical analysis
During the stability testing process, cosmetic chemists monitor the samples’ physical and chemical changes, including pH, viscosity, appearance, and fragrance. By analyzing these factors, they can determine how the product may change over time and anticipate future problems before they arise.
Step 6: Evaluation
Once the stability testing is complete, cosmetic chemists evaluate the results and determine whether the product meets the desired shelf life and quality standards. This process includes assessing the product’s physical and chemical properties, as well as any microbial growth and sensory changes.
