Interactions
incompatible with: No major direct incompatibilities are known., Formulation performance depends on the overall emulsifier system and oil phase; avoid assuming it will stabilize highly unusual electrolyte or solvent loads without testing.
Risks & Warnings
Generally low risk. Possible mild irritation or sensitivity in very reactive skin, usually from the finished formula rather than the ingredient itself. As with many silicone emulsifiers, heavy use in very occlusive formulas may feel rich on acne-prone skin, though it is typically considered low-comedogenic.
