Fragrance Chemical Crystallization in Refrigerator

Crystallization in fragrance chemicals like Lilial/Lilestralis, Cyclamen propanal/Bourgeonal, and Para-cresol when stored at cold temperatures, such as in a refrigerator, is a common physical phenomenon. It does not typically indicate that the chemical is damaged or unusable. The crystals are simply the solid form of the chemical at that temperature.

To return these chemicals to their liquid state for use, you need to gently warm them until the crystals dissolve.

Here is the recommended method:

• Gentle Warming: Place the sealed containers of the crystallized chemicals (Lilial/Lilestralis, Cyclamen propanal/Bourgeonal, and Para-cresol) in a warm water bath. Ensure the water is warm, not hot or boiling. A temperature below 50°C (120°F) is usually sufficient and safe. Alternatively, you can leave the bottles at room temperature for a period, or gently warm them with a low-setting hairdryer.
• Swirling: Once the chemical starts to melt, you can gently swirl the bottle to help the remaining crystals dissolve more quickly.
• Avoid High Heat: Do not use excessive heat, as this could potentially degrade the fragrance chemical or damage the container.
• Storage: To prevent future crystallization, it is best to store these fragrance chemicals at room temperature unless their specific product information explicitly requires refrigeration.

This gentle warming process should fully dissolve the crystals, allowing you to use the fragrance chemicals as intended.
