Stability Testing for Cosmetics

Cosmetic stability test is a study of the physical, chemical, and microbiological stability of a product from production until the end of its life, under defined storage conditions. Protheragen provides a full range of iron metabolism-related cosmetics development services and offers stability testing services dedicated to ensuring compliance with safety, stability, and efficacy standards. Our cosmetic stability testing includes long-term and accelerated stability testing, photostability testing, shelf-life prediction, and more.

Overview of Stability Testing for Cosmetics

Cosmetic stability testing is a necessity when developing cosmetic products. It measures, scientifically, how a cosmetic product's physical, chemical, microbiological, and performance characteristics evolve over time through the influence of a range of environmental factors (for instance, temperature, light, and humidity). This essential process ensures your product is safe, effective, and maintains the quality you expect over the product's shelf life and under normal consumer use.

Classification of Stability Testing for Cosmetics

Stability tests may be performed in real time or under accelerated conditions and cover evaluation of product stability concerning its storage, transport, and use. It typically involves monitoring and testing product samples under controlled conditions that mimic different storage and usage practices. This closely observed monitoring detects any changes in the products. Essentially, there are three types of stability testing:

Physical / Chemical Stability Tests

Assessment of color, odor, or fragrance, pH, texture, viscosity, flowing properties, and emulsion separation checks are physical and chemical integrity tests. Predicting how well cosmetics withstand temperature extremes and exposure to light is important for testing cosmetics’ stability.

  • Temperature Variations
  • Cycle Testing
  • Cycle Testing
  • Light Exposure Testing
  • Mechanical Shock Testing
  • Others

Microbiological Stability Tests

Microbiological stability tests assess the level of contamination with bacteria, molds, and yeasts. The microbial safety of cosmetics ensures safety for the consumer, preserves product quality, and guarantees hygienic and high-quality handling during production.

  • Screening Tests
  • Quantitative Tests

Packaging Stability Tests

Evaluation of the effects of packaging on the product contained within is a packaging stability test. The interactions that may happen between the product, the package, and the surrounding environment can influence the stability of the finished product.

  • Glass Tests
  • Weight Loss Tests
  • Leaking Tests
  • Others

Cosmetic Types for Stability Testing

Stability Testing Services for Cosmetics

Long-Term Stability Testing

Long-term stability testing is used to assess the various properties of cosmetic samples under the expected storage conditions.

Accelerated Stability Testing

Monitor and evaluate cosmetic characteristics under controlled accelerated conditions (e.g., high temperature/high humidity).

Photostability Test

Study the stability and degradation of the product after controlled irradiation with specific light sources (light including UV).

Emulsion Stability Test

Test the stability of emulsions by centrifugation testing under controlled conditions for formulations containing powders.

Packaging Stability Test

Special testing to assess the interaction between packaging components and contents, material durability (heat/light/mechanical), and integrity.

Microbiological Stability Test

Identify and quantify microbial contamination by means of qualitative methods, semi-quantitative and quantitative methods.
