Recently, I have been on a quest to find every last description of the white fluid that flows through a synthetic human's artificial veins to ultimately determine the best official name for the substance.
Below, I am working on compiling every description I can find regarding the stuff. Please feel free to add to the conversation!
While Alien: The Weyland-Yutani Report makes mention of a patent for the realistic skin used for synthetics, it makes no mention of a patent for "synthesized blood" to my knowledge.
- "Thick white ichor–the substance that flowed through a synthetic's artifical veins–rained down from the ceiling.." - Aliens: Prototype
Personally, I feel like "ichor" is the most suitable word to be an official name for the "circulating fluid", which is a term used throughout the Alien novels, most often to describe the liquid that drips from a Xenomorphs mouth and body.
++ Recently, Aliens: Fireteam Elite called it Liquid Replenishment Latex ++
Ichor (Webster's definition) - The fluid that flows like blood through the veins of the gods.

- "..as the white lubricant that passed for synthetic blood oozed out of its shoulder.." - Alien: Isolation (novel)

- "..ripping limbs from torsos, spraying circulating fluid up in thin white fountains." & "..white polymer circulating fluid.." & "Tubules, shunts, circulatory lines.." - Aliens: Earth Hive
- "White fluid spurted from the torn body, android blood.." - Aliens: Nightmare Asylum (novel)
- "Science model 270D4. Made with high iron and copper hydation and conductor fluid. Red. Like blood." - Aliens: More Than Human
- "White fluid splattered everywhere.." "On the stump of her neck, where the rest of her body used to be, white tubes pumped her last fluid out onto the floor.." - Aliens: Rogue (novel)
- "Judith wasn't built to withstand so much; her milky fluids splattered.." - Aliens: Labyrinth (novel)
- "..the sudden white splash of the demolished android's nutrient and lubrication fluids." - Aliens: Music of the Spears (novel)

- "Dipping his fingers into the pooling synthetic blood in Marcus's wound, he lifts them to his lips. It has a taste like aspertame, with a breathy undertone of truffle oil." - Alien: The Cold Forge

- "It wasn't a conscious decision, it was one his volume processor, his brain, had simply ordered in the interest of self-preservation. The artificial organ that regulated the flow of hydraulic fluid through his trunk, head, and limbs had increased its rate of flow." - Aliens: Bug Hunt - Broken
- "When he hits okay, it goes to a coolant balancing screen. "Bishop, come in," he says into his walkie." - Alien: Into Charybdis
