Hyaluronic Acid
HTL is the world leader in the production of pharmaceutical grade Hyaluronic Acid (hyaluronan) by fermentation. This biopolymer is naturally present in the human body where it plays an essential role in several physiological functions. It has been a key ingredient for many different types of biomaterials, medical devices and pharmaceutical products for several decades, and still has great potential for innovation.

HYALURONIC ACID AS A COMPONENT OF THE HUMAN BODY
Hyaluronic Acid, also known as Hyaluronan, is a natural component of most connective tissues, such as synovial fluid and the vitreous humor of the eye, it is involved in tissue hydration and structural scaffolding and provides viscoelasticity, which results in lubrication and shock absorbing functionalities.
Hyaluronic Acid is also involved in more advanced functions. With its ability to bind to multiple extracellular proteins distributed among numerous pathophysiological systems, it contributes to the modulation of many biochemica processes such as cell proliferation and differentiation, cell adhesion and inflammation, wound healing and tissue repair.
HYALURONIC ACID AS A COMPONENT OF MEDICAL PRODUCTS
With its renowned natural functions, combined with the fact that it is biocompatible, non-immunogenic, biodegradable and able to be further functionalized by chemical modification, Hyaluronic Acid is a key raw material or component for many biomaterials, medical devices and pharmaceutical products today, including injectables, eye-drops, hydrogels or topical medications, It is used as a dermal filler, protects eye tissues during ophthalmic surgery, is injected as a visco-supplement for osteoarthritis, is used for the surface coating of medical devices in surgery, and a wide range of additional applications.
The current most prevalent functional uses are:
- Filling, bulking in aesthetics and urology
- Tissue protection in cataract surgery
- Visco-supplementation in rheumatology, in dermatology and ophthalmology
- Medical device coating in surgery
Additionally, Hyaluronic Acid is increasingly investigated and used in advanced applications such as:
- Anti-inflammatory, wound healing in dermatology, rheumatology, dental surgery
- Drug carrier in oncology
- Scaffold for tissue engineering in regenerative medicine and medical research
- Shield for surgical sites and wound healing promoter in implantology
Why molecular weight matters?
The mechanical and biological properties of Hyaluronic Acid are directly linked to the size of the molecule and to molecular weight. The lower the molecular weight, the lower the viscosity, However, the biological response of cells (such as an angiogenic effect) is significantly impacted, A higher molecular weight, conversely leads to a higher viscosity, that is required for certain medical applications such as biomaterials.
