My body wash seems to get watered down as I use it. What’s happening?

Assuming that no water has entered the chamber, some varieties of liquid soap, body wash or shampoo may absorb ambient humidity due to their formulation. Whether used from the original bottle or a dispenser, products of this formulation may get thinner as warm, wet air is exposed to the cooler liquid inside. Although this occurrence may not be completely preventable, we do recommend that you ensure each of your dispenser lids are properly seated and bottle caps kept closed to minimize this effect.
