Why might water-based OC sprays be preferred over oil-based versions?

Water-based OC sprays are often preferred over oil-based versions primarily due to their easier cleanup characteristics. When a water-based spray is used, it can be washed off more easily with soap and water. This is particularly advantageous in confrontational situations, as it minimizes the duration of discomfort for everyone involved, including the subject who has been sprayed. The ability to remove the spray quickly can lower the risk of prolonged exposure effects, making it a more practical choice in various scenarios where rapidly resolving the situation is essential.

In contrast, oil-based sprays can cling to surfaces and skin for a longer period of time, making them more challenging to remove. This can lead to ongoing irritation and may complicate post-incident procedures for law enforcement. Additionally, other factors such as potency, pain level, and duration of effect relate to different qualities of the sprays, and not necessarily to the water or oil-based formulation.
