Science
Mechanism of Action
This amphiphilic molecule utilizes a long-chain behenyl (C22) group to form a waxy, breathable lattice on the skin's surface, significantly reducing Trans-Epidermal Water Loss (TEWL). Simultaneously, its PEG-10 units provide humectant properties and allow the ingredient to act as a versatile emulsifier (HLB 4-6) for stabilizing complex water-in-oil and water-in-silicone systems.
Research
Clinical Evidence
High confidence5%
Key findings
- 01 Clinical assessments on 39 subjects confirmed that a 40% concentration in aqueous solution is non-irritating.
- 02 A large-scale study involving 201 volunteers established no signs of sensitization or irritation for this class of PEG-modified silicones.
- 03 Testing of undiluted material (100% concentration) on 50 subjects demonstrated zero instances of skin irritation.

Dusting Analysis
As a structural and sensory modifier, it is typically used at functional levels (1-15%) rather than 'dusting' levels. Concentrations below 0.5% in emulsions may indicate its use purely for label claims rather than significant textural or barrier benefit.
The Formula
Formulation
Stability
Maintains structural integrity in neutral and mildly acidic or alkaline environments. Avoid exposure to strong mineral acids or oxidizing agents which can degrade the siloxane backbone.
Synergies

- Concentrated mineral acids
- Strong alkalis
Safety
Safety Profile
The 15% concentration limit is the current industry reference for leave-on products, though the ingredient has shown safety at much higher concentrations in clinical settings.
