Microplastics
Cashmere is recorded as Natural Fiber with no listed microplastic polymer, so it does not add a microplastic-source penalty.
Cashmere is a specialty animal fiber with defined labeling requirements. “Cashmere feel” does not establish cashmere content; look for the actual named percentage.
Greener Closet scores a plain 100% Cashmere label at 80/100. It is not a plastic fiber, so the score adds no microplastic penalty. The label does not show which dyes or finishes were used, and those can change the score.
For knitwear, compare the cashmere share, other fibers, construction and care. Price or softness alone is not verification of fiber identity.
The FTC’s wool labeling guidance distinguishes cashmere from other wool and specialty fibers. The fiber name is not a finished-article chemical certification.
The composition label does not establish animal-welfare verification, fiber quality, dye chemistry or durability of the exact sweater.

Greener Closet scores the disclosed share using the corresponding MaterialsDB record. Its factor defaults are model assumptions, not product testing, a factory life-cycle assessment or independently validated quantitative calibration.
Cashmere is recorded as Natural Fiber with no listed microplastic polymer, so it does not add a microplastic-source penalty.
MaterialsDB does not apply a base PFAS penalty to Cashmere. Product-level water, stain, or performance finishes can still change PFAS risk.
Cashmere has no persistence penalty in MaterialsDB, which generally reflects better biodegradability than petroleum-based synthetics.
Cashmere has no default microfiber-shedding penalty in MaterialsDB. Garment construction and laundering still matter.
Cashmere carries a manufacturing-energy penalty, so production impacts remain part of the score even when microplastic risk is low.
Paste the full fabric label into the homepage checker. A 95% cotton, 5% elastane garment will not score the same as 100% cotton, and the checker handles those percentages.

Cashmere is on the look-for or watch-out list for these categories. Each guide ranks scored products and explains what the fiber label can tell you.
Cashmere has no listed microplastic polymer in MaterialsDB. Garment construction and washing can still release fibers.
Cashmere has no half-life penalty in MaterialsDB, which is a better biodegradability signal than petroleum-based synthetics.
Use the Greener Closet material-label checker with the full percentage label, because blends can change the final score even when Cashmere is only one part of the garment.
