Many plastics, like commercial shopping bags, contain chemicals often referred to as "slip agents," which are derived from the stearic acid in animal fat. They essentially prevent the polymers from sticking to metals during manufacturing and clinging to each other afterward. Some bike tires also contain these elements.

Also known as cochineal dye or natural red 4, carmine is derived from the cochineal insect, which when crushed produces a vivid red pigment. Carmine is produced when the powdered insects are purified to extract the bright pigment. It’s very widely used as a food colouring, for lipsticks, and in textile weaving.

Gelatin is a protein that lacks in an essential amino acid tryptophan, and hence cannot be considered as a sole source of protein in animal or human nutrition. But it is a relatively high source of lysine and methionine, which are deficient in cereal proteins. However, gelatin finds extensive use in food as also in the formulation of some industrial products. Gelatin can be extracted from the skin and bones of fish.
