A European ophthalmic pharmaceutical manufacturer has long focused on the research and development and production of artificial tears and dry eye care products. With increasing market competition, the client plans to launch a new generation of artificial tears emphasizing "long-lasting lubrication and sustained hydration" to meet the needs of users who spend long hours on electronic devices, the elderly, and those with mild to moderate dry eye.

In the early stages of product development, the client tested various lubricating ingredients but found that some raw materials had issues with short moisturizing time and insufficient contact time with the ocular surface, requiring frequent application and impacting the user experience. After several rounds of screening, the client contacted our company, hoping to find a sodium hyaluronate raw material with excellent viscoelasticity, high purity, and good biocompatibility.

Based on the client's formulation requirements and target viscosity range, our technical team recommended high molecular weight sodium hyaluronate suitable for eye drops and provided detailed technical information, samples, and application suggestions. The client conducted formulation compatibility, viscosity stability, and moisturizing performance tests in the laboratory. The results showed:

After laboratory verification, the client confirmed that the raw material met their product development requirements. Ultimately, the client successfully launched their new long-lasting artificial tears product and successfully entered several European markets.
