Cosmetic products contain active ingredients that are intended to nourish, repair or protect the skin from negative influences. To ensure that these active ingredients remain undamaged on their way from the producer to the consumer and during application, an ideal compatibility of formulation and packaging is necessary. However, there is an increasing demand for recyclable, recycled, bio-based or overall more sustainable packaging. Can these packaging materials provide the same protective function as conventional packaging materials? To verify this, time-consuming stability tests have been conducted to date. With an innovative shelf-life modeling tool, it may be possible for manufacturers to predict shelf life several months into the future in just a few moments.
