“Integrated” hydrocolloids were invented by a predecessor company of Xennovate Medical with the first patent for a hydrocolloid that did not “disintegrate” (hence the name, “Integrated”) due to moisture content over time. Hydrocolloids found their first large market in ostomy adhesives holding the collection bags securely onto the stomach without skin damage.
Nurses caring for and training ostomy patients at the time, then started noticing that the number and seriousness of skin problems typically seen around the stoma were not appearing as they had in the past while using Karaya Gum adhesives. Also, those with damaged skin from the use of Karaya Gum demonstrated full healing after starting to use hydrocolloids as their pouch adhesive.
Those peri-stoma skin healing successes led to a new use for hydrocolloids as moist wound healing bandages. The “pre-integrated” years held the risk of “…deep seated, unresolved inflammation in tissue that otherwise appears healed,” due to the melting of the hydrocolloid into the wound beds, while the integrated versions took that risk away as D. Chakravarthy noted in his publication:, “Evaluation of three new hydrocolloid dressings: Retention of dressing integrity and biodegradability of absorbent components attenuate inflammation”
