Emulsifying Wax, commonly referred to as E Wax, is a nonionic emulsifier widely used in cosmetic and personal care formulations. It helps to blend oil and water phases, creating stable emulsions with a smooth and consistent texture. E Wax is typically derived from vegetable sources and is composed of a mixture of fatty alcohols and ethoxylated fatty alcohols.
INCI Name:
Cetearyl Alcohol (and) Polysorbate 60 or Cetostearyl Alcohol (and) Ethoxylated Sorbitan Ester
CAS Numbers:
- Cetearyl Alcohol: 8005-44-5
- Polysorbate 60: 9005-67-8
Uses:
- Emulsifier: Facilitates the formation of stable oil-in-water (O/W) or water-in-oil (W/O) emulsions.
- Thickener: Contributes to the viscosity and texture of creams and lotions.
- Stabilizer: Enhances the stability and shelf-life of emulsions by preventing phase separation.
- Moisturizer: Provides a smooth, non-greasy feel to formulations and imparts emollient properties.
Applications:
- Skin Care Products: Creams, lotions, serums, and ointments.
- Hair Care Products: Conditioners, masks, and styling creams.
- Makeup: Foundations, primers, and other color cosmetics.
- Pharmaceuticals: Topical ointments and creams.
- Sunscreens: Emulsions that require stability under various conditions.
Usage Guidelines:
- Concentration: Typically used at concentrations between 2% and 10% in formulations.
- Incorporation: Usually added to the oil phase of a formulation and melted during the heating process.
- Heating: Both oil and water phases should be heated to 70-75°C to ensure proper emulsification.
Formulation Tips:
- Heating: Heat both the oil phase (containing E Wax) and the water phase to around 70-75°C before combining.
- Blending: Mix the oil phase into the water phase slowly while maintaining the temperature and stirring continuously.
- Cool Down: Continue stirring as the mixture cools to room temperature to ensure a smooth, uniform emulsion.
- pH Adjustment: If necessary, adjust the pH of the final product to match the desired skin compatibility.
Additional Information:
- Appearance: White to off-white waxy solid.
- Solubility: Dispersible in water when heated; soluble in oil.
- HLB Value: Typically around 15, suitable for oil-in-water emulsions.
- Storage: Store in a cool, dry place away from direct sunlight and moisture.
Safety:
- Irritation: Generally considered non-irritating and safe for use in cosmetics and personal care products.
- Handling: Standard protective measures (gloves, goggles) are recommended to avoid direct contact.
