Pharmaceutical Grade Propylene Glycol: A Key Excipient in Drug Formulation
NINGBO INNO PHARMCHEM CO.,LTD. is a premier supplier of high-purity chemical compounds, and our pharmaceutical grade propylene glycol is instrumental in the development and manufacturing of safe and effective pharmaceutical products. With its CAS number 57-55-6, pharmaceutical grade propylene glycol is a widely recognized and utilized excipient in the global pharmaceutical industry.
The primary function of pharmaceutical grade propylene glycol in drug formulations is its role as a solvent. It effectively dissolves a wide range of active pharmaceutical ingredients (APIs), making them available for absorption and delivery within the body. This is particularly important for APIs that have poor water solubility. Its use as a co-solvent in combination with water or other solvents can significantly improve the solubility and bioavailability of many medications.
Furthermore, propylene glycol acts as a humectant, which means it helps to retain moisture. This property is valuable in topical formulations such as ointments, creams, and lotions, where it helps to keep the skin hydrated and prevent the product from drying out. In oral liquid medications, it can also contribute to a more palatable texture and stability.
As a stabilizer, pharmaceutical grade propylene glycol helps to maintain the physical and chemical integrity of drug products over time, extending their shelf life. It can also act as a viscosity enhancer, contributing to the desired consistency of liquid and semi-solid dosage forms, which can impact ease of administration and patient compliance. For those looking to buy propylene glycol liquid for pharmaceutical applications, NINGBO INNO PHARMCHEM CO.,LTD. ensures the highest standards of purity and quality.
The demand for pharmaceutical grade propylene glycol is driven by its versatility and proven safety profile when used as an excipient. It is found in a wide variety of pharmaceutical products, including oral solutions, injectable formulations, topical preparations, and even some ophthalmic solutions.
