What is LQD® Spray?

LQD® Spray is an innovative and unique spray-on primary dressing containing Chitosan FH02® for the external, local treatment of chronic wounds, acute wounds and superficial partial thickness burns.

The active ingredient in LQD® Spray is Chitosan-FH02®. Chitosan FH02® supports haemostasis, promotes granulation tissue formation and is a natural anti-microbial. It can also help to reduce wound pain.

Chitosan - FH02®

Invented by nature, refined and activated by us for effective wound healing. LQD® Spray is a natural product free from artificial additives or preservatives.

The active ingredient of LQD® Spray is chitosan.

The chitosan in LQD® Spray is modified to become the innovative Chitosan FH02® which has a higher positive charge and the highest degree of de-acetylation of any chitosan product.

The chitosan used for LQD® Spray is derived from the shell of the Norwegian Arctic Sea shrimp which is specifically processed for medicinal use and is not treated with medicines. This is one reason why the chitosan used for LQD® Spray can be described as ultrapure.


Chitosan is structurally similar to hyaluronic acid and other glycosaminoglycans found in humans. The polymer chitosan has a positive surface charge that enables a specific electrostatic interaction with cell surfaces and other biomolecules. As a result, chitosan is known to have a range of beneficial effects:
