Difference between Polyethylene Wax and Synthetic Wax

Polyethylene Wax and Synthetic Wax are both synthetic waxes used in cosmetic formulations, but they have different chemical structures and properties, which means they are listed under different INCI names (Polyethylene vs Synthetic Wax).

• Polyethylene Wax: This is a polymer known for providing good surface coating without feeling greasy. It adds stability to formulas, gives a soft and dry feel on the skin, increases color pay-off in makeup, and can help enhance SPF and waterproof properties in sunscreens. It is available in different hardness levels and melting points (e.g., 88°C, 113°C).
• Synthetic Wax: This type of wax is often highlighted for its use in lipstick formulations. It helps provide shine, improves color pay-off, and can reduce "sweating" (the formation of small droplets) on the lipstick surface. It is also available with different melting points (e.g., 88°C, 108°C).

While they share some functional similarities, particularly in providing structure and improving texture, their specific characteristics and optimal applications can differ. For example, Polyethylene Wax is noted for its film-forming and waterproofing benefits, while Synthetic Wax is specifically mentioned for its performance in lipsticks regarding shine and sweat reduction.

Can they be used interchangeably?

They might be used interchangeably in some basic formulations where the primary goal is simply to increase viscosity or hardness. However, due to their different chemical compositions and specific properties, they are generally not a direct one-to-one substitute, especially in formulations where a specific feel, finish, or performance characteristic (like waterproofing or sweat reduction in lipstick) is critical. Always test substitution in your specific formula to ensure the desired outcome is achieved.
