Our client is a company specializing in the development of injectable cosmetic products, primarily including mesotherapy and dermal fillers. During product development and registration, the client had stringent requirements for sodium hyaluronate raw materials, particularly regarding safety and stability. However, in the initial supplier collaborations, the client encountered significant problems: high endotoxin levels in the raw materials, making it difficult to meet injectable-grade standards; significant quality fluctuations between different batches, affecting formulation stability; and the supplier's inability to provide complete and standardized quality documentation, hindering the registration process. These issues directly impacted product development progress and market launch plans.

To address the client's high standards for injectable applications, we provided high-purity injectable-grade sodium hyaluronate raw materials, focusing on controlling endotoxin levels and microbial indicators to ensure the product met stringent safety requirements. Simultaneously, by optimizing the fermentation and purification processes, we achieved stable control of molecular weight distribution, ensuring consistency between batches. Furthermore, based on the client's specific formulation needs, we provided customizable molecular weight ranges and related technical parameters, along with complete quality documentation, including Certificate of Analysis (COA), endotoxin test reports, and microbial limit data, thus comprehensively supporting the client's R&D and compliance application efforts.

After adopting our raw materials, the client successfully completed internal quality validation, significantly improved formulation stability, and effectively controlled batch-to-batch variations. Simultaneously, comprehensive technical documentation greatly enhanced the completeness of registration materials, accelerating the product filing and approval process. The client reported that their end products met expected standards in terms of safety and user experience, and highly praised the consistency and reliable supply of raw materials. This has led to the establishment of a long-term and stable cooperative relationship between the two parties.
