Microplastics
Organic Cotton is recorded as Natural Fiber with no listed microplastic polymer, so it does not add a microplastic-source penalty.
Grown without synthetic pesticides or fertilizers. Uses 91% less water than conventional cotton, supports biodiversity, and is fully biodegradable.
Greener Closet scores materials from several penalty inputs. The same material can be reasonable in one product and weak in another, but these are the default drivers behind the base material record.
Organic Cotton 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 Organic Cotton. Product-level water, stain, or performance finishes can still change PFAS risk.
Organic Cotton has no persistence penalty in MaterialsDB, which generally reflects better biodegradability than petroleum-based synthetics.
Organic Cotton has no default microfiber-shedding penalty in MaterialsDB. Garment construction and laundering still matter.
Organic Cotton carries a manufacturing-energy penalty, so production impacts remain part of the score even when microplastic risk is low.

Organic Cotton shows up frequently in these categories. Each guide explains which fibers and finishes to look for and to avoid.
Organic Cotton has no listed microplastic polymer in MaterialsDB, though garment construction and washing still affect fiber release.
Organic Cotton 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 Organic Cotton is only one part of the garment.
