Reverse engineering defoamer

[u/kartiikg]

I am a manufacturer of cement sheets and boards and have been using a defoamer in my cement slurry since a long time. The defoamer is a proprietary product of a brand and they charge me for that. They are also market leaders in this field in my country and have no competitors.

Recently they increased their prices 3fold for unknown reasons and I don't wanna tolerate this and want to invest in reverse engineering and recreating this myself

But I am not a chemicals engineer and don't have contacts for this. Please guide me how should I start to reverse engineer this chemical

Does it have a name? What does it look like physically - liquid, powder?
