On the bottle of structure gel is a label denoting hazards, production number, and a QR code. If scanned, the QR code says "structure gel 023343".

I also noticed after digging through the files and replaying SOMA a couple weeks ago that, along with Haimatsu and Carthage Industries, there seems to be two other, minor companies; Niurou Fan Food Corp and Golem, Niurou Fan providing food and food related products, as the name suggests, and Golem providing both hand tools and electrical tools. I really like these tiny details.
There's also a brand/company called "Desirain" as seen on this image posted by David Satzinger, but I've hard no luck with finding where the logo is used in SOMA.
