Ethylhexyl Cocoate
1. What It Is & How It’s Used in Cosmetics
INCI: Ethylhexyl Cocoate is a fatty ester formed from 2-ethylhexanol and coconut fatty acids. It serves as a lightweight, non-greasy emollient that improves spreadability and imparts a silky skin feel. Usage levels span widely, from as low as 0.01% up to 41% in formulations, depending on sensory goals and formulation type. The CIR Expert Panel concluded it is safe for use when formulated to be non-irritating and under typical use levels [2][4]. It is not flagged as problematic by EWG’s Skin Deep database [5].
2. Technical Details & Characteristics
-
Appearance: Clear to pale yellow liquid
-
Function: Emollient, skin-conditioning agent, slip enhancer
-
Form Compatibility: Oil-soluble; blends easily in oil phases of emulsions and anhydrous systems
-
Typical Use Levels: 1–30%, depending on texture and form type
-
Safety: CIR-approved; broad use is acceptable when not irritating [2]
-
Sensory Attributes: Smooth silicones-like feel with lower viscosity; improves sensory experience in lotions, serums, and sunscreens
3. How to Formulate (Independent Formulator Guidance)
-
Usage Role: Use as a primary or secondary emollient to enhance slide and finish
-
Phase: Add to oil phase; easily incorporated at room temperature or with low heating (≤60 °C)
-
pH Stability: Oil-phase ingredient—unaffected by pH; focus pH adjustments on water phase components
-
Compatibility: Smoothly blends with oils, esters, silicones, sunscreen filters, emollient blends, and co-emulsifiers
-
Stability Notes: Standard stability testing—heat/cool cycling, centrifugation, and room temp storage—recommended to ensure no phase separation
