This is due to its own material

Defoaming agents are mostly mixtures, mainly carriers or additives of defoaming agents. There are many types of defoamers, such as silicone oil, polyethers, and higher alcohols, among which minerals and vegetable oils are also involved. The presence of these substances can easily produce oil.
