ABOUT THE PRODUCT

Product Description

Product Description-Propylene Glycol CAS#57-55-6


Propylene Glycol USP/EP/FCC (CAS 57-55-6) is a ≥99.5% high-purity liquid solvent and humectant meeting global pharmacopeia standards. The USP grade serves as a low-endotoxin (≤0.5 EU/ml) injection solvent for pharmaceuticals; in cosmetics, it acts as an OECD 439-certified low-irritant humectant; the FCC grade functions as an antifreeze carrier in food processing (21 CFR 184.1666). Featuring low-toxicity antifreeze performance with a freezing point of -59°C (ASTM D1384), it is also suitable for industrial applications, and technical documentation is available.

Product Applications-Propylene Glycol CAS#57-55-6


Propylene Glycol (CAS 57-55-6) is a key multifunctional ingredient with excellent solubility and low toxicity, widely used across industries. USP-grade PG functions as a low-endotoxin (≤0.5 EU/ml) solvent for oral and transdermal pharmaceutical formulations; in cosmetics, it delivers OECD 439-certified moisturizing benefits to enhance hydration in lotions and serums; FCC-grade PG serves as a safe antifreeze carrier in food processing in line with 21 CFR 184.1666; and industrial fields benefit from its reliable antifreeze performance with a freezing point of -59°C (ASTM D1384). Technical documentation is available for industry-specific needs.
