Silicone Defoamer
TL;DR This catalog product is a silicone-emulsion defoamer, with a white to light-yellow appearance, weak-anionic emulsion identity and published pH reference of 6.5–8.5. A silicone formulation is distinct from a polyether antifoam; emulsion form and process compatibility matter alongside concentration.

Compare the application
Identify stable surface foam versus entrained air, then reproduce the actual liquid, temperature, mixing and feed point. Compare foam suppression, recurrence, deposits, filtration and finished-product quality. The silicone family name does not establish harmlessness or an unlimited temperature or pH window.
