Stability and Compatibility Testing

We at Chromak Research provide Stability and Compatibility Testing of cosmetic and personal care products with utmost care. This crucial testing ensures that your formulations are stable, effective, safe, possessing good texture and appearance throughout their shelf life and under various conditions of storage. As a reliable contract testing laboratory, we assist cosmetic companies, producers, and formulators in launching high-quality and compliant products in the market.

What is Stability and Compatibility Testing?

Stability and Compatibility Testing is a scientific method which identifies the extent to which a cosmetic product retains its quality with the passage of time after exposure to various environmental stress conditions like temperature, humidity, and light. It also examines how the formulation is compatible with pack materials. These tests ensure that the finished product is stable, safe, and visually consistent over the recommended shelf life.

Why Stability Testing in Cosmetics?

Stability testing is crucial in the cosmetic and personal care sector in order to:

  • Ensure consistency and reliability of the product

  • Accommodate shelf life claims

  • Prevent product degradation, separation, discoloration, or microbial growth

  • Regulatory compliance with international regulations (e.g., FDA, EU Cosmetic Regulation)

In Chromak Research, our stability and compatibility testing prevents expensive recalls, sustains consumer trust, and having products enter the marketplace with confidence.
