Medium-chain triglycerides (MCT) are a blend of triglycerides formed by the esterification of caprylic and capric saturated fatty acids with glycerol. They appear as a colorless to slightly yellow, clear oily liquid and are a mainstream pharmaceutical-grade lipid raw material. This product is manufactured by Baiyunshan Hanfang, with CDE registration number Y20200001227 (Status A). It meets the triple quality standards of the Chinese Pharmacopoeia (CP), the United States Pharmacopeia (USP), and the European Pharmacopoeia (EP). It is widely used in the production of various fat emulsion preparations, soft capsules, eye drops, and other pharmaceutical products, serving both as a carrier for lipophilic drugs and as a source of essential fatty acids to provide rapid energy. MCT is metabolized quickly and completely in the human body, without imposing an additional metabolic burden on the liver or the immune system, making it a core oil-phase ingredient for formulation development and large-

The core structure of liposomes is a phospholipid bilayer, and the phospholipid composition directly determines their encapsulation efficiency, microstructure, and stability, making it a key optimization parameter in liposome preparation. This paper elucidates the mechanisms by which phospholipid composition affects liposome stability, providing a reference for formulation design and quality control.
In modern pharmaceutical formulations, phospholipid excipients, owing to their unique structure and functions, are widely employed in advanced drug delivery systems such as liposomes, emulsions, and nanoparticles. They serve not only as “carriers” for drugs but also as the “skeleton” of the formulation; their quality directly impacts the stability, safety, and efficacy of the drug. So, how exactly does the quality of phospholipid excipients affect pharmaceutical preparations? Today, we’ll delve into this question by examining several key quality indicators.
Baiyunshan Hanfang’s liposome raw materials utilize advanced phospholipid bilayer encapsulation technology to effectively enhance the absorption rates of active ingredients such as curcumin, NMN, silymarin, and coenzyme Q10. With stable resistance to degradation and targeted delivery, we supply liposome raw materials for health foods and cosmetics, and offer customized development of liposome ingredients along with comprehensive formulation support services.
