Science
Mechanism of Action
As a surfactant, Sekken Soji actively reduces the surface tension between oil and water, facilitating their mixture and enabling the detachment and removal of fat and soil particles from the skin's surface. This mechanism also contributes to its notable foaming capabilities, enhancing the sensory experience of cleansing products.

Safety
Safety Profile
Sekken Soji is generally understood as a 'soap base,' synthesized from animal or vegetable fatty acids and sodium hydroxide. While not specifically reviewed by CIR or SCCS, a related INCI name, 'SEKKEN SOJI-K,' is permitted for use by the CFDA in China. Conflicting data exists regarding its irritancy potential: some sources suggest a 'likelihood of irritation,' potentially causing inflammation or dryness, whereas others classify its irritancy risk as 'LOW'.
