Casein— curdled milk.
Gelatin—. Gelatin is a protein made by boiling cows' and pigs' skin, tendons, ligaments, and bones. Um, ew !
Honey—many bees die when the honey is stolen from them, due to being crushed, stepped on, and from stinging the beekeepers to protect themselves. I know I'd fight back if someone tried to step my room, so can you blame those poor little bees ?.

Rennet—an enzyme taken from baby calves' stomachs, is used for/in cheese production.
Stearic Acid—found often in chocolate and vitamins, comes from a fatty substance taken from slaughtered pigs' stomachs—or from cows, sheep, or dogs and cats euthanized in animal shelters. This rates at #1 on the “OMG EW” scale in my mind lol.
Cetyl Palmitate—waxy oil derived from sperm whales' heads or from dolphins.

Straight from Wikipedia:
Stearic acid is useful as an ingredient in making candles, plastics, dietary supplements, oil pastels and cosmetics, and for softening rubber.[2] It is used to harden soaps, particularly those made with vegetable oil.
Stearic acid is also used as a parting compound when making plaster castings from a plaster piece mold or waste mold and when making the mold from a shellacked clay original. In this use, powdered stearic acid is dissolved in water and the solution is brushed onto the surface to be parted after casting.
Esters of stearic acid with ethylene glycol, glycol stearate and glycol distearate are used to produce a pearly effect in shampoos, soaps, and other cosmetic products. They are added to the product in molten form and allowed to crystalize under controlled conditions.
In fireworks, stearic acid is often used to coat metal powders such as aluminium and iron. This prevents oxidation, allowing compositions to be stored for longer.
It is used along with simple sugar or corn syrup as a hardener in candies.
Stearic acid is one of most used lubricants during injection molding of ceramic powders.[3]
