Science
Mechanism of Action
It operates as an occlusive lubricant that integrates into the stratum corneum's lipid matrix. By forming a fine-textured film, it fills the gaps between desquamating skin cells, which significantly lowers transepidermal water loss (TEWL) and restores pliability to the skin's surface.

Clinical Evidence
High confidence1.5%
Key findings
- 01 Human Repeat Insult Patch Tests (HRIPT) on up to 202 subjects confirmed no sensitization at concentrations of 1.5%.
- 02 Clinical evaluation at 0.7% demonstrated zero irritation or sensitization across 198 human participants.
- 03 Ocular testing indicates the ingredient is non-irritating to eyes at 1.5%, though concentrated forms (100%) act as an irritant.

Dusting Analysis
While often used in small amounts for texture, clinical safety and efficacy data focus on the 0.7% to 1.5% range. Formulae using less than 0.5% may be utilizing it for basic glide rather than therapeutic emolliency.

Stability
Highly stable within standard cosmetic pH ranges but vulnerable to hydrolysis into alcohol and acid when exposed to extreme pH environments.

Verdict
An excellent emollient for dry and sensitive skin profiles, though its moderate comedogenicity suggests it should be avoided in acne-prone or very oily formulations.
