High concentrations of fatty alcohols and mixed surfactants often lead to phase separation or crystal growth over time. Resolving this instability ensures product shelf-life and consistent sensory delivery.

Complex surfactant systems often suffer from phase separation or insufficient viscosity under varying thermal and mechanical conditions. Maintaining structural integrity in multi-component cosmetic bases ensures consistent delivery of active agents.

High surface friction and structural roughness of keratin fibers lead to tangling and poor tactile properties. Reducing these mechanical impediments improves hair manageability and sensory quality.
