Science
Mechanism of Action
It functions by decreasing the interfacial tension between disparate oil and water phases, allowing them to form a cohesive emulsion. Its high HLB (Hydrophilic-Lipophilic Balance) value of approximately 17.8 makes it exceptionally water-soluble, acting as a protective colloid that stabilizes complex dispersed systems and aids in the gentle removal of debris during cleansing.
Research
Clinical Evidence
High confidence5%
Key findings
- 01 Clinical patch testing at 1.5% and 10% concentrations demonstrated minimal irritation potential and no evidence of sensitization across 4-day and 21-day trials.
- 02 Safety assessments indicate the ingredient is non-mutagenic and non-toxic within the standard effective range of 0.5% to 10% for solubilization.

Dusting Analysis
As a functional emulsifier rather than an active treatment, 'dusting' is less applicable; however, concentrations below 0.5% may indicate it is being used merely as a secondary stabilizer rather than a primary solubilizing agent.
