Why “octasiloxane” is a great word
A siloxane compound containing eight silicon-oxygen repeating units in its molecular structure. From the combining form octa- ("eight") and siloxane, a compound containing a chain of alternating silicon and oxygen atoms. Unlike hexasiloxane, which denotes a chain of six, or polysiloxane, which implies an indefinite polymer length, octasiloxane specifies a precise, small oligomer. It is the engineered hinge in a foldable screen, the liquid bead that rolls cleanly off a raincoat, the invisible film that seals a surface without a trace—the satisfaction of a complete, countable thing in a world of vague abundance.
Etymology
From octa- + siloxane.
noun
- Any siloxane having eight -Si-O- groups
