Mechanism of Action of Oxidized Polyethylene Wax in Candles

1. Improving Softening Point and Strength

    Oxidized polyethylene wax is produced by oxidizing polyethylene and features a high softening point (above 100°C). When added to candles, it increases the overall softening point of the candle, preventing deformation even in relatively high-temperature environments. At the molecular level, the molecular structure of oxidized polyethylene wax interacts with the main components of the candle, enhancing intermolecular forces and thereby increasing the candle’s strength, making it more robust and durable.

2. Enhancing Surface Gloss

    Oxidized polyethylene wax can make the candle surface smoother and more lustrous. This is because it forms a relatively uniform film on the candle surface, which reflects light to improve gloss. During candle production, this effect enhances the aesthetic appearance of the candle and increases product attractiveness.

3. Promoting Safe Combustion

    When the candle is lit, oxidized polyethylene wax contributes to a safe, bright, and smokeless burning effect. It improves the combustion performance of the fuel in the candle, enabling more complete combustion. By reducing the surface tension of the fuel, it facilitates better contact between fuel and oxygen, thereby increasing combustion efficiency, reducing black smoke from incomplete combustion, and ensuring safe and stable burning.

4. Improving Dispersion Uniformity

    Oxidized polyethylene wax has excellent dispersibility. During the raw material mixing process in candle production, it promotes uniform dispersion of additives, pigments, and other components in the candle’s base material. This helps ensure consistent overall quality, with uniform distribution of color, fragrance, etc., avoiding local variations.
