Information @ a Glance


  • A hydrocolloid is defined as a colloid system wherein the colloid particles are dispersed in water.
  • Hydrocolloids can be either irreversible (single-state) or reversible.
  • Hydrocolloids are extremely versatile.
  • Hydrocolloids are hydrophilicb polymers, of vegetable, animal, microbial or synthetic origin, that generally contain many hydroxyl groups and may be polyelectrolytes.

Process & Preparation

  • The hydrocolloids process manufactures carrageenan, clarified locust bean gum and other hydrocolloids.
  • Preparation of the reversible hydrocolloid involved a careful combination of the ingredients to assure a homogeneous mixture.
  • Hydrocolloids retard the rate of water crystallization and that some are more effective than others.

Application & Technology

  • Hydrocolloids is used for Ostomy Applications.
  • Hydrocolloids - which are thickening, gelling and stabilizing agents used mainly in food and beverage products, as well as oil field and pharmaceutical products.
  • Hydrocolloids are primarily used on decubitus ulcers, but are also used to a lesser degree for dressing second degree burns and donor sites.
  • Removal techniques will ensure appropriate use of TegadermTM Hydrocolloid and TegadermTM Thin Hydrocolloid.
  • An Impression Technique is used to obtain accuracy of reproduction results with reversible hydrocolloid.


  • The global hydrocolloid market is expected to grow at about 2.8%/ year, valued at $3.9 billion by 2012.
  • The hydrocolloid market's growth is slowing because dressings from other markets are slowly taking a bite out of the market.
  • For hydrocolloids, the biggest market is Europe, followed by the Americas - although it does depend somewhat on the technology.
