Science
Mechanism of Action
Its hydrophobic octenylsuccinate chains efficiently absorb excess sebum and sweat without clumping. This action reduces surface tension, modifies formula rheology, and provides a dry-touch feel, while also potentially modulating active ingredient absorption.

Key findings
- 01 Sensory analysis on 60 volunteers showed a 2% concentration promoted a soft, velvety feel and significantly reduced skin oiliness in sunscreen formulations.
- 02 Effectively used in sunscreens to reduce the greasiness of UV filters and provide a dry-touch finish, potentially enhancing SPF.
Transparency
Dusting Analysis
While used in powdered and spray formulations, its typical particle size (~13.5 microns) is generally considered non-respirable, mitigating inhalation concerns.
The Formula
Formulation
Stability
Stable across a wide cosmetic pH range (3.5-9.0) in both oil-in-water and water-in-oil emulsions. It is insoluble in cold water and requires dispersion for optimal integration.
Conflicts
- Strong oxidizing agents
- Extremely high alkaline conditions (may cause hydrolysis)
Safety
Safety Profile
The CIR Expert Panel confirmed safety up to 30%, provided heavy metal limits (lead, arsenic) for food-grade starch are not exceeded. Clinical tests at 30% showed little irritation or sensitization.
