What is Elastane/Spandex?

Elastane, also known as Spandex, is a synthetic fiber known for its exceptional elasticity. It is a polyurethane-polyurea copolymer that is produced by reacting a polyester with a diisocyanate.

This fiber is widely used in various types of clothing, including jeans and sports bras, to provide stretch and comfort. There is limited health impact from wearing elastane, as it is mostly considered safe for direct skin contact. Concerns are mostly related to its environmental impact, as it is a non-biodegradable synthetic material.

When shopping for clothing, elastane ensures a snug fit and flexibility. However, its synthetic nature means it doesn't break down naturally, contributing to microplastic pollution.

Commonly found in: Jeans, Sports Bras, Activewear, Leggings, Underwear, Swimwear

What to watch

  • The production and disposal of elastane contribute to environmental pollution due to its non-biodegradable nature.

Benefits

  • Elastane provides excellent elasticity, improving the comfort and fit of clothing items like sportswear and denim.
FDA

Elastane is not regulated as a food ingredient, but it's widely used in textiles with no specific restrictions.

Research

Research emphasizes elastane's environmental impact rather than health effects, as it does not typically pose health risks when used in textiles.

Vegan

Elastane is a synthetic fiber and is not derived from animals, making it suitable for vegan use.

Scout's take

Elastane or spandex is a synthetic material used for stretch, typically in small percentages (1-4%). While it enhances fit and comfort, it is a synthetic fiber that can contribute to microplastic pollution.

More from Scout's analyses

The inclusion of elastane or spandex for stretch is common in jeans, and it typically represents a small percentage, but it is still a synthetic material that can contribute to microplastic pollution.
