Science
Mechanism of Action
This ingredient facilitates the creation of lyotropic liquid crystals within an emulsion, forming lamellar phases that structurally mimic the skin's natural intercellular lipid bilayer. By integrating into the stratum corneum, it effectively repairs the barrier function and significantly minimizes transepidermal water loss (TEWL).

Key findings
- 01 Ilic et al. (2021) demonstrated that 5% concentrations provide high hydration potential and serve as an effective delivery system for actives while maintaining a safe irritation profile.
- 02 Tasic-Kostov et al. (2011) confirmed via 28-day in vivo trials that concentrations between 3-5% significantly increase stratum corneum hydration and reduce TEWL through lipid-bilayer biomimicry.

Dusting Analysis
Because this ingredient also serves a functional role in stabilizing the emulsion's viscosity, it is rarely 'dusted' at negligible amounts; however, to achieve the clinically proven barrier-repair benefits, a concentration of at least 1-3% is required.
The Formula
Formulation
Stability
Maintains exceptional stability across a broad pH spectrum. Requires thermal processing (75-85°C) to incorporate into the oil phase. Its non-ionic nature ensures broad compatibility with various actives.
Synergies
- Arachidyl Glucoside
- Lactobionic Acid
- Lipophilic active substances
Conflicts
- High electrolyte concentrations
- Strong oxidizers
- Extreme mineral salts
Safety
Safety Profile
Recognized by the CIR Expert Panel as a safe cosmetic ingredient. While used up to 25% in some leave-on formulas, its primary efficacy for barrier support is found at much lower levels.
