Lighting requirements (most crucial)
Crotonin is highly sensitive to visible light and ultraviolet light:
✅ The entire process must be carried out in a **fully dark environment**. The warehouse uses dark storage rooms without fluorescent lights, and the containers must be dark brown or black
❌ Natural light exposure and long-term exposure to ordinary indoor lights are prohibited. Leaving it exposed for just a few days can cause it to deteriorate.
Air and Humidity
1. The container must be tightly sealed and must not have any openings. Exposure to air can cause oxidation and deterioration.
2. Environmentally dry: Relative humidity 40% – 65%. Protection against moisture is sufficient. This product does not dissolve in water and is not prone to absorbing moisture.
3. Long-term storage recommendation: Fill with inert gas (nitrogen) to isolate the air.
