Spandex (Elastane)
What is Spandex (Elastane)?
Spandex, also known as elastane, is a synthetic fiber known for its exceptional elasticity. It is made by reacting polyester with a diisocyanate, a process that involves several chemical transformations.
Spandex is widely used in clothing due to its ability to stretch significantly yet return to its original shape. It's a key component in workout apparel, swimwear, and other garments. The health evidence surrounding spandex mostly pertains to its safety as a fabric and allergic reactions are rare, but possible.
When you see spandex on a product label, it typically indicates the product's ability to provide stretch and flexibility, rather than any dietary or topical effect.
Commonly found in: Workout Tops, Leggings, Swimwear, Undergarments
