The cosmetics and personal care industry utilizes incubators extensively for product safety and efficacy testing, often adhering to strict regulatory guidelines (like those from the EU or FDA). Preservative Efficacy Testing (PET) or Challenge Testing is a prime example. Finished products (creams, lotions) are inoculated with known concentrations of bacteria (e.g., S. aureus, P. aeruginosa) and fungi (e.g., C. albicans, A. brasiliensis). Samples are then incubated at specified temperatures (e.g., 20-25°C for fungi, 30-35°C for bacteria) over 28 days. Viable microbes are counted at intervals to ensure the product’s preservative system effectively reduces contamination to safe levels. Incubators are also used for stability testing, where products are stored at elevated temperatures and humidity (e.g., 40°C, 75% RH) to accelerate aging and predict shelf life.

Furthermore, in vitro skin irritation or corrosion tests using reconstructed human epidermis models require incubation at 37°C and 5% CO2 to maintain tissue viability before and during exposure to test substances. The incubator, in this context, ensures that claims about product safety, shelf-life, and compatibility are backed by standardized, controlled, and reproducible scientific data.
