Researchers have reported degradation of RTX resiniferatoxin solution stored in various plastic containers.

Therefore, we investigated the stability of stock solutions stored in a commonly used plastic material and in glass, under differing conditions of temperature, light and dark.

It clearly emerges that: (a) both room temperature and light exposure affect RTX stability and the combined effect of these factors is additive; (b) RTX degradation, if present, falls to a nadir at 48 hours; (c) At low temperatures, in the dark, plastic storage affords better stability than glass.
