Microplastics
Material-class model assumption
Viscose is recorded as Regenerated Cellulose Fiber and tied to no listed microplastic polymer, which drives the material's microplastics score pressure.
Regenerated Cellulose Fiber
Viscose clothing: health and sustainability score
Viscose is regenerated cellulose: plant cellulose is processed into a manufactured fiber. It is different from a mechanically extracted plant fiber such as linen.
Where it shows up
For dresses, shirts or loungewear, compare the full blend, opacity, care label and return policy rather than assuming that a plant origin predicts the finished fabric.
What the evidence supports
Textile definitions distinguish viscose from lyocell. A claim about one named lyocell process should not be transferred to all viscose.
What remains unknown
The generic fiber name does not disclose the pulp source, factory controls, dye or finished-item residue measurements.

How the model interprets this fiber
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.
Low concern
PFAS uncertainty
Material-class model assumption
MaterialsDB does not apply a base PFAS penalty to Viscose. Product-level water, stain, or performance finishes can still change PFAS risk.
Half-life and biodegradability
Material-class model assumption
Viscose has no persistence penalty in MaterialsDB, which generally reflects better biodegradability than petroleum-based synthetics.
Fiber shedding
Material-class model assumption
Viscose has no default microfiber-shedding penalty in MaterialsDB. Garment construction and laundering still matter.
Manufacturing energy
Material-class model assumption
Viscose carries a manufacturing-energy penalty, so production impacts remain part of the score even when microplastic risk is low.

Best next step
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.

Common questions
Does Viscose clothing shed microplastics?
Viscose has no listed microplastic polymer in MaterialsDB. Garment construction and washing can still release fibers.
Is Viscose biodegradable?
Viscose has no half-life penalty in MaterialsDB, which is a better biodegradability signal than petroleum-based synthetics.
How should I check a Viscose blend?
Use the Greener Closet material-label checker with the full percentage label, because blends can change the final score even when Viscose is only one part of the garment.
