Science
Mechanism of Action
This complex utilizes sphinganine-based ceramides (Ceramide NG) to improve the structural cohesion and elasticity of the skin and hair. By replenishing essential lipids and inhibiting pro-inflammatory cytokines like Interleukin-1 (IL-1), it simultaneously reduces trans-epidermal water loss and calms inflammatory responses triggered by environmental stress.

Key findings
- 01 In vitro models demonstrated a significant decrease in IL-1 protein release in UV-stressed keratinocytes at a 1% concentration.
- 02 An in vivo study involving 40 participants confirmed a visible reduction in scalp erythema, itching, and dryness.
- 03 Technical evaluations showed hair structural strengthening and thermal protection at concentrations between 0.1% and 1.0%.

Dusting Analysis
Because this ingredient is effective at low concentrations (as low as 0.1% for hair repair), it is less likely to be 'dusted' than bulkier actives, though efficacy for scalp soothing is most robust at the 1% mark.
The Formula
Formulation
Stability
The ingredient is heat-stable up to 80°C and suitable for both cold and hot processing. It is supplied without preservatives or antioxidants.
Synergies
- Other barrier-identical lipids
- Squalane
- Tocopherol
Conflicts
- Strong oxidizing agents
- Highly alkaline environments (risk of ester hydrolysis)
Safety
Safety Profile
While the complex as a whole is awaiting a specific CIR monograph, its individual components—Castor Seed Oil, Olive Fruit Oil, and Ceramide NG—are well-established as safe for cosmetic use.
