Säilyvyystutkimuksin, which translates to "shelf-life studies" in English, refers to the systematic evaluation of how long a product remains suitable for its intended use under specified storage conditions. This is a crucial aspect of product development and quality control across various industries, including food, pharmaceuticals, cosmetics, and chemicals. The primary goal of shelf-life studies is to determine the period during which a product retains its essential characteristics, such as efficacy, safety, and sensory attributes, without significant degradation.

These studies involve subjecting products to various environmental factors that can influence their stability. Common parameters tested include temperature, humidity, light exposure, and packaging integrity. Products are often stored under accelerated conditions (e.g., higher temperatures) to predict their long-term stability more quickly, alongside real-time storage studies that mimic actual consumer conditions. Analytical methods are employed to monitor changes in the product over time. These methods can range from physical and chemical analyses, such as measuring pH, viscosity, or active ingredient concentration, to microbiological testing to detect microbial growth. Sensory evaluation by trained panelists is also frequently incorporated, especially for food and cosmetic products, to assess changes in taste, odor, texture, and appearance.

The data gathered from shelf-life studies is essential for establishing expiration dates or recommended usage periods. This information ensures consumer safety by preventing the use of degraded or potentially harmful products and helps manufacturers manage inventory and reduce waste. Regulatory bodies often require detailed shelf-life data to approve product sales, particularly in highly regulated sectors like pharmaceuticals and food. Effective shelf-life studies contribute significantly to product quality, consumer trust, and regulatory compliance.
