E-Wax (Emulsifying Wax)
The Essential Emulsifier for DIY Lotions & Creams
What Is E-Wax?
E-Wax (Emulsifying Wax) is a blend of fatty alcohols (e.g., cetearyl alcohol) and non-ionic surfactants (e.g., polysorbate 60 or steareth-20). It acts as a stabilizer, binding oil and water phases in skincare products to create smooth, homogeneous emulsions.
Key Features
- Composition:
- Cetearyl Alcohol: A fatty alcohol that thickens and stabilizes.
- Polysorbate/Sorbitan Derivatives: Surfactants that reduce surface tension between oil and water.
- Forms:
- E-Wax NF: Common in cosmetics, often plant-derived (vegan-friendly).
- BTMS: Conditioning emulsifier (contains behentrimonium methosulfate for hair products).
How to Use
- Typical Concentration: 3–5% of total formula weight.
- Process:
- Melt E-Wax with the oil phase (oils, butters) at 70–75°C (158–167°F).
- Combine with heated water phase (water, hydrosols, glycerin).
- Blend thoroughly until emulsified, then cool while stirring to avoid separation.
- Applications:
- Creams, lotions, conditioners, body butters, and balms.
Benefits
✨ Stable Emulsions: Prevents oil and water from separating.
✨ Rich Texture: Creates luxurious, non-greasy creams.
✨ Versatile: Works in both oil-in-water (O/W) and water-in-oil (W/O) emulsions.
✨ Skin-Friendly: Non-comedogenic and suitable for most skin types.
Safety & Tips
- Patch Test: Rare sensitivities possible (e.g., to surfactants).
- Storage: Keep in a cool, dry place; finished products stable for 6–12 months.
- Troubleshooting:
- Grainy Texture: Overheating or rapid cooling—stir slowly while cooling.
- Separation: Insufficient E-Wax or mixing—reheat and re-emulsify.
