Massallah pertaining to Ghusul water

Bismillah wassalam’aleykum Shaykh,
What is the type of water left on the palm of my hand after rubbing a limb with it during wudu or ghusl?Purifying water or used (musta’mala) water?
(there is always some drop of water still on the palm of the hand after rubbing a limb…)
Wassalam
