Short answer
Stoma powder, also called ostomy powder, is a skin-care accessory sold for use around a stoma, the surgically created opening for an ostomy. It sits in the same supply category as pouches, barriers and skin prep wipes. In the United States, ostomy pouches and their accessories are regulated as Class I devices under 21 CFR 876.5900, and how an individual powder is classified depends on its labeling.
Definition and scope
An ostomy diverts stool or urine to a stoma, and a pouch attached to the skin with adhesive collects it. The FDA regulation for this equipment, 21 CFR 876.5900, covers the “ostomy pouch and accessories,” and lists the ostomy pouch, ostomy adhesive, ostomy collector, stomal bag, ostomy protector and ostomy size selector among them. Stoma powder is something staff meet next to pouches and barriers in supply catalogues. Memorial Sloan Kettering (MSKCC) patient education uses the term “ostomy powder” and discusses it together with skin prep wipes. For the pouch itself, see what an ostomy bag is.
Where stoma powder sits among ostomy supplies
- Pouches and stomal bags: the collection device attached to the skin.
- Adhesives and barriers: the materials that hold the pouch to the skin.
- Skin prep wipes: a related peristomal skin product that MSKCC names alongside powder.
- Stoma powder: a skin-care accessory used around the stoma.
Product instructions, ingredients and suitability are set out in each manufacturer’s labeling, and choices for an individual belong with the care team.
How stoma powder is regulated
The FDA’s product code EXE is titled “Protector, ostomy.” It sits under 21 CFR 876.5900, is Device Class 1, and has the definition “Ostomy pouch and accessories” (FDA product classification database, record updated 2026-10-26, checked 2026-10-30). Under the regulation (eCFR, version dated 2026-10-01), Class I means general controls, and the devices are exempt from premarket notification (510(k)), subject to the limitations in 21 CFR 876.9. A broader explanation of classes is in what counts as a medical device, and recall classes are covered in FDA recall classification.
The regulation names the category, not individual products. How a particular powder is classified depends on its labeling, so a supply team should rely on the manufacturer’s labeling rather than assuming from the category.

Common misunderstandings
“A Class I listing means every product is the same”
The class belongs to the regulatory category. It says nothing about the formulation or labeling of a particular product.
“The regulation lists powders by name”
21 CFR 876.5900 names the ostomy pouch, adhesive, collector, stomal bag, protector and size selector. It does not name powders, so a powder’s status is read from its labeling.
FAQ
What is stoma powder?
A skin-care accessory sold for use around a stoma. It is one of the accessories that sit alongside ostomy pouches.
Is stoma powder the same as ostomy powder?
The terms are used for the same kind of accessory. MSKCC’s patient education uses “ostomy powder.”
Does it need FDA clearance?
Ostomy accessories fall under 21 CFR 876.5900 (Class I, exempt from 510(k) subject to 876.9). A specific product’s status depends on its labeling.
Where can questions about using it be answered?
With the person’s WOC nurse or doctor, and in the product’s own labeling. This page gives general product and regulatory information only.
