What are the differences between cold and warm diffusion methods for fragrance oils?
Cold and warm diffusion methods offer distinct ways to disperse fragrance oils, each suited to different needs and preferences. Cold diffusion methods, such as reed diffusers, nebulizers, and ultrasonic diffusers, work without heat. This approach preserves the full integrity of the fragrance, ensuring that the scent remains true to its original profile. Cold diffusion is energy-efficient and safer, as it eliminates risks associated with heating elements. However, it disperses fragrance more gradually and might not cover larger spaces as effectively without additional airflow. Warm diffusion methods, like oil burners and heated diffusers, use heat to evaporate fragrance oils. This allows the scent to spread quickly and fill larger spaces, creating a cozy ambiance, especially in cooler weather. However, the use of heat can alter or degrade certain scent notes, and there is a higher risk of burns or fire if not handled carefully. Warm diffusion also tends to consume more energy.
