Products from HTL

  • Hyaluronan / hyaluronic acid by HTL

    Product Hyaluronan / hyaluronic acid by HTL

    Hyaluronic acid, also known as Hyaluronan, is a biopolymer that is naturally present in the human body. It has been used for many years as a raw material or ingredient for medical products in various fields including ophthalmology, orthopaedics and dermatology.
    HTL produces injectable grade Hyaluronic Acid for premium medical applications. It is a product of non-animal, natural origin, obtained in HTL’s state-of-the-art manufacturing facilities in France.

    HTL has a long history of providing the best quality on the market, in terms of purity level, batch to batch consistency and stability. HTL provides the widest range of options, having the unique ability to produce hyaluronan from a very low to a very high molecular weight (from 8kDa to 4.5MDa, intrinsic viscosity up to 3.8m3/kg). HTL can produce hyaluronan in fiber form.

    HTL can supply tailor-made functionalized derivatives of hyaluronic acid.
  • Chondroitin by fermentation by HTL

    Product Chondroitin by fermentation by HTL

    While most Chondroitin sulfate on the market is of animal origin, HTL is developing a new source of Chondroitin of non-animal origin with the use of fermentation. Chondroitin sulfate can then be obtained by sulfation. 

    Characteristics and benefits of Chondroitin by fermentation: 
    • absence of animal traces and prion contamination
    • helps protect endangered animal species
    • access to a Chondroitin with higher molecular weight, which opens up the potential for new applications
    HTL can produce Chondroitin with a Molecular Weight around 50 kDa (Chondroitin Sulfate) or 400 kDa (non-sulfated Chondroitin). HTL is your partner for the development of tailor-made functionalized Chondroitin derivatives such as Chondroitin sulfate.

    Today’s applications: rheumatology, ophthalmology.
    Potential applications: tissue engineering, oncology, anti-inflammatory and anti-viral potential

  • Heparosan by HTL

    Product Heparosan by HTL

    HTL is developing Heparosan, a promising raw material for the design of innovative medical devices. Under license, HTL will be the sole producer of medical grade, high molecular weight Heparosan by fermentation (20 kDa to 2MDa). Safe for use in humans, Heparosan is an endogenous GlycosAminoGlycan with a structure very close to that of hyaluronan, but it cannot be hydrolyzed by hyaluronidase enzymes. HTL is your partner for the development of tailor-made functionalized derivatives such as Heparosan sulfate.

    The physico-chemical and biological characteristics of Heparosan will enable to produce a variety of superior biomaterials, gels and scaffolds, with a potentially increased lifetime and water retention capability compared to existing biomaterials.

    Potential applications: ophthalmology, orthopedics, aesthetics, dermatology, coating of medical devices, tissue engineering, drug delivery systems development.

  • Functionalized GlycosAminoGlycan Derivatives

    Product Functionalized GlycosAminoGlycan Derivatives

    HTL offers the tailor-made development of functionalized derivatives of Glycosaminoglycans, such as modified Hyaluronic Acid, Heparosan and Chondroitin. Developing new functionalities by chemical modification allows the optimization of existing uses of these biopolymers, but also opens opportunities for new medical applications. 

    Typical chemical modifications: Hydrazidation, epoxy grafting, sulfation, silylation, deacetylation, alkylation

    New functionalities thanks to chemical modification: 

    Optimizing physico-chemical properties
    • Viscodynamic properties
    • Solubility in biological media
    Delaying degradation
    • Extended half-life
    • Improved resistance to oxidative stress and catabolic enzymes
    Modulating biological properties
    • Tissue adhesion
    • Tissue integration
    • Tissue improvement
    • Targeted delivery
