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
