Sulfate-free cleansing systems inherently lack the salt-induced thickening response of traditional surfactants. Achieving consumer-acceptable rheology without compromising mildness is a persistent performance bottleneck.

Sulfate-free surfactant blends often fail to achieve the consumer-required thickness and rheological stability. Resolving this limitation ensures product suspension and improved application aesthetics.

Sulfate-free systems often fail to effectively deposit functional actives like salicylic acid or minerals onto surfaces during rinsing. Improving deposition efficiency ensures therapeutic efficacy and sensory performance in mild surfactant bases.
