Science
Mechanism of Action
This high-molecular-weight ester functions by creating a breathable, occlusive film across the stratum corneum. This physical barrier effectively mitigates trans-epidermal water loss (TEWL) and refines the skin's micro-relief, resulting in a smoother texture and enhanced hydration retention without the heaviness associated with traditional plant butters.

Key findings
- 01 A 4.0% concentration was clinically validated as minimally irritating in human patch testing with a Primary Irritation Index of just 0.08.
- 02 Testing at 1.2% demonstrated no irritation in 24-hour single-insult patch tests.
- 03 Rabbit ear assays confirmed the undiluted material (100%) is non-comedogenic, though its profile may shift slightly when combined with specific carrier oils like mineral oil.

Dusting Analysis
As a consistency-builder and emollient, this ingredient is typically used at functional levels (2-15%) to achieve the desired texture; use below 1% may suggest it is included for label claims rather than structural or skin-conditioning benefits.
The Formula
Formulation
Stability
Highly resistant to oxidation and rancidity, offering superior shelf-life stability compared to natural butters. It maintains a low melting point for ease of formulation.
Synergies
- Mineral pigments
- Lipophilic active ingredients
- Silicone alternatives
Conflicts
- Strong oxidizing agents
- Extreme pH environments (below 3.0 or above 10.0) which may trigger ester hydrolysis
Safety
Safety Profile
Recognized as safe within the cosmetic industry, with a typical maximum usage of 15% in leave-on skin applications to ensure optimal compatibility.
