**Definition and Importance**

Photostability evaluates a product's ability to withstand exposure to light. This is a critical consideration for products exposed to natural or artificial light, such as pharmaceuticals, cosmetics, and food items. Light resistance is essential to ensure that these products maintain their effectiveness, safety, and physicochemical properties throughout their shelf life.

**Methodologies Used**

We employ tests following ICH Q1B guidelines for our photostability studies, ensuring results that comply with internationally recognized standards. Our tests involve controlled exposure of products to specified light sources, accurately replicating real-world usage and storage conditions.

**Targeted Products**

For pharmaceuticals, we test dosage forms like tablets, capsules, syrups, and injectables. In cosmetics, our studies include products such as sunscreens, serums, and lotions. For food products, we evaluate items like juices, oils, and other light-sensitive products.

This rigorous approach ensures that our clients can trust in the quality and safety of their products, even under prolonged exposure to light conditions.

**Definition and Importance**

Forced degradation aims to accelerate the decomposition of products to identify degradation pathways and potential degradation products. This is crucial for understanding the chemical and physical stability of a product.

**Methodologies Used**

Extreme Conditions: Our tests involve extreme conditions of temperature, humidity, pH, and oxidation to accelerate degradation.
Advanced Analysis: We use techniques such as high-performance liquid chromatography (HPLC) and spectroscopy to analyze degradation products.

**Targeted Products**

Pharmaceuticals: Solid and liquid medications.
Cosmetics: Skincare products, makeup.
Industrial: Chemicals, adhesives, paints.

**Definition and Importance**

In-use stability evaluates the lifespan of a product after opening or reconstitution. This is crucial for products that are not consumed immediately after opening.

**Methodologies Used**

Realistic Simulations: Our studies simulate real-world usage conditions to determine how long the product remains stable and effective after opening.
Performance Testing: We assess physical, chemical, and microbiological changes that may occur during use.

**Targeted Products**

Pharmaceuticals: Multi-dose vials, injectable solutions after reconstitution.
Cosmetics: Creams, lotions, makeup.
Food Products: Beverages, perishable items after opening.

This assessment ensures that consumers use products safely and effectively throughout their intended use period, minimizing health risks and ensuring product quality.
