What are the components of hydrocolloid used in ostomy care?

• A. Carboxymethyl cellulose, pectin, and gelatin
• B. Gelatin, Carboxymethyl cellulose, and pectin
• C. Carboxymethyl cellulose, pectin
• D. Gelatin and carboxymethyl cellulose

Answer: (A)

Hydrocolloid wafers used in ostomy care are built from a blend of carboxymethyl cellulose, pectin, and gelatin. Each component plays a vital role in forming the protective, moisture-managing gel that cushions and protects peristomal skin. Carboxymethyl cellulose acts as a thickener and gel-forming polymer, helping the material swell and create a cohesive matrix. Pectin adds to gel formation and water absorption, enhancing the hydrocolloid’s ability to manage moisture around the stoma. Gelatin provides elasticity and gel strength, helping the gel stay intact as it cushions the skin and maintains the seal. Together, these three create the characteristic hydrocolloid that protects skin while absorbing moisture; missing any one element would weaken the gel network and reduce performance.
