Motivation

There is growing interest in detergent products that are not only more sustainable but also gentler on the skin. Due to their high surfactant content, these products inherently present a risk of skin irritation. However, it is widely documented that surfactant mixtures can generate synergistic effects that mitigate this impact by forming larger and more stable micelles. Relevant synergies are also observed when these mixtures include polymers or other additives capable of modifying key parameters such as protein denaturation, effects on the skin barrier, or cellular cytotoxicity.
At the same time, these interactions may enhance formulation efficacy in aspects such as soil removal, foam generation, and active ingredient deposition. In parallel, within the Home Care sector, consumers are increasingly sensitive to the use of products that are more respectful of both the environment and skin health. This trend has driven many companies to reformulate their product lines and to promote claims such as “eco‑friendly,” “sustainable,” or “made with natural ingredients”.
