Is Elastane (Spandex) Vegan?

I

Rest easy, Elastane is vegan.

Elastane, known as spandex in North America, is a polyester-polyurethane copolymer (plastic).

It’s made completely in a lab, with no animal ingredients used along the way.

Elastane is incredibly stretchy, but is still stronger than materials like rubber.

Is Elastane Fabric Vegan?

Elastane fabric is made from more than just elastane itself.

It’s a combination of other materials like:

  • Cotton
  • Polyester
  • Linen
  • Nylon

It is almost always vegan, made with synthetic fibers.

However, it’s also made with “natural” fibers, so there may be a few rare occasions where it’s made with a non-vegan material.

In general, seeing elastane or spandex in the materials list is a good sign for vegans.

  • I suppose it depends how far back in the process you go. Elastane may be finished using magnesium stearate, which in turn may be derived from an animal source. This raises a question of how complex manufacturing makes traceability more problematic. Also, how far back is it reasonable or practical to go.
    I’ve been trying to source work gloves with high cut protection, but which don’t have any animal products. Latex is another issue, as I’m informed it may be a component used to add elasticity. but of course it may contain casein. Maybe I should just go and lie down for a bit!
