Mechanism of Action
This ingredient acts as a structural analog to naturally occurring cholesterol sulfate. It facilitates the organization of intercellular lipids into a liquid crystal 'multi-lamellar' phase, which is critical for maintaining a functional permeability barrier. Additionally, it helps regulate the desquamation process by modulating steroid sulfatase activity, preventing the premature shedding of the stratum corneum.

Dusting Analysis
While effective at low concentrations, this ingredient is often used as a 'label claim' in generic moisturizers. At Moumoujus, we recognize its efficacy is strictly dependent on being formulated within a precise 1:1:1 ratio alongside pseudo-ceramides and fatty acids to achieve true lamellar restoration.
The Formula
Formulation
Stability
Highly stable in both O/W and W/O emulsions, especially those utilizing lamellar phase technology. Its amphiphilic nature allows it to integrate seamlessly at the interface of lipid bilayers.
Synergies
- Pseudo-ceramides
- Fatty Acids
- Cholesterol
Conflicts
- Environments with pH below 4.0 (risk of sulfate ester hydrolysis)
- High concentrations of divalent cations other than calcium
Safety
Safety Profile
Derived from phytosterols which are recognized as safe cosmetic components. The calcium and sulfate ions are physiologically compatible and non-toxic.
