Science
Mechanism of Action
This ingredient acts as a classic emollient by occupying the microscopic gaps between corneocytes (surface skin cells) to smooth the skin's physical texture. It establishes a breathable, semi-occlusive film that significantly minimizes Transepidermal Water Loss (TEWL), ensuring sustained hydration and barrier resilience.

Key findings
- 01 A comprehensive CIR Expert Panel safety assessment (2012) confirmed that isoparaffins are non-sensitizing and maintain safety even under UV exposure.
- 02 Safety data for related branched hydrocarbons demonstrates non-irritating profiles in leave-on applications at concentrations as high as 90%.
Transparency
Dusting Analysis
As a functional solvent and emollient, C14-16 Isoparaffin is typically used at significant levels to achieve desired formula texture and stability, making it rarely subject to 'active dusting' marketing tactics.
The Formula
Formulation
Stability
Highly chemically inert; it is resistant to both hydrolysis and oxidation, remaining stable across a broad pH range and various environmental conditions.
Safety
Safety Profile
The CIR Expert Panel noted that while some rat studies suggested nephrotoxicity, the mechanism is specific to a protein humans do not possess (α2u-globulin), making it irrelevant to human topical safety.
