Science
Mechanism of Action
This ingredient establishes a breathable, viscoelastic film on the skin's surface, acting as a hydrophobic shield to significantly reduce transepidermal water loss (TEWL). Its specific molecular structure allows it to effectively fill intercellular gaps within the stratum corneum, reinforcing the skin's natural defense against external irritants while maintaining optimal gas exchange.
Research
Clinical Evidence
High confidence15%
Key findings
- 01 A 2021 CIR Safety Assessment confirmed that concentrations up to 15% are non-irritating and exhibit zero significant dermal absorption.
- 02 Human Repeated Insult Patch Tests (HRIPT) at 5.0% concentrations demonstrated no potential for dermal sensitization or allergic reaction.
Transparency
Dusting Analysis
As a functional texture enhancer and barrier agent, it is typically used at effective concentrations to achieve the desired skin feel; however, concentrations below 1% may indicate it is being used primarily for label claims rather than significant occlusive benefits.
