Science
Mechanism of Action
It operates as an occlusive emollient by forming a thin, lipidic film over the stratum corneum. This barrier physically restricts trans-epidermal water loss (TEWL), effectively trapping moisture within the skin layers while simultaneously stabilizing the non-aqueous phase of emulsions to improve product texture and consistency.

Key findings
- 01 Clinical read-across assessments by the CIR indicate that longer-chain 1,2-glycols (C15-30) possess high lipophilicity and a molecular size that prevents deep dermal penetration, ensuring localized efficacy without systemic absorption.

Dusting Analysis
As a structural and emollient ingredient rather than a primary bioactive, it is typically used for its physical properties; however, because it lacks a standard reported maximum concentration, it is rarely used in 'dusting' marketing claims.
The Formula
Formulation
Stability
Extremely resilient across a wide pH spectrum and heat-stable with an estimated boiling point exceeding 400°C, making it ideal for high-temperature emulsion processing.
Safety
Safety Profile
The CIR Expert Panel supports its safety based on the ingredient's large molecular weight, which significantly limits skin penetration.
