Menstrual pad

A menstrual pad is absorbent material worn in underwear to collect menstrual blood. Pads may be disposable or reusable.

Absorbent core: The inner layer of an absorbent product that takes up and holds liquid. It stores menstrual fluid beneath the pad’s surface.
Reusable menstrual pad: A washable cloth pad worn in underwear to collect menstrual blood. It replaces single-use pads through repeated washing and reuse.
Menstrual hygiene management: Practices and conditions that enable people to manage menstruation safely, privately, and with dignity. Pads are one option within the broader needs of menstrual care.
Tampon: An absorbent product inserted into the vagina to collect menstrual blood. It collects fluid internally, unlike a pad worn in underwear.
Cellulose: A plant-derived polymer that forms the structural framework of plant cell walls. Wood pulp and cotton cellulose are common absorbent materials in pads.
Disposable menstrual pad: A menstrual pad designed for one use before disposal. It is the common alternative to washable cloth pads.
Period poverty: Inadequate access to menstrual products, facilities, education, or related support because of financial or social barriers. The cost and availability of pads can affect reliable menstrual care.
Menstrual cup: A reusable cup inserted into the vagina to collect menstrual fluid. It collects rather than absorbs fluid and is worn internally.
Superabsorbent polymer: A cross-linked polymer that can absorb and retain large amounts of liquid relative to its mass. Disposable pads may use it to increase fluid retention in a thin core.
Maternity pad: A large absorbent pad designed to collect bleeding after childbirth. Its greater coverage suits postpartum bleeding rather than ordinary menstrual flow.
