Q1: What is the primary functional role of Dow Propylene Glycol PGI in industrial formulations?
A: Dow Propylene Glycol PGI serves primarily as a versatile solvent, humectant, and formulation stabilizer—particularly valued for its low volatility, low toxicity profile, and excellent compatibility with water, alcohols, and many polymers.
Q2: Is Dow Propylene Glycol PGI suitable for use in food-contact applications?
A: Yes—Dow Propylene Glycol PGI is manufactured to meet U.S. FDA requirements for indirect food additives (21 CFR §172.858) and is widely used in food packaging inks, coatings, and adhesives where incidental contact may occur. Final regulatory compliance depends on the full formulation and intended application.
Q3: How does Dow Propylene Glycol PGI compare to conventional propylene glycol in performance-critical applications?
A: Dow Propylene Glycol PGI is specifically refined for enhanced purity and consistency, offering lower residual odor, reduced acidity, and improved color stability—making it preferred in high-performance inks, cosmetics, and sensitive polymer systems where batch-to-batch reproducibility matters.
Q4: What are typical handling and storage recommendations?
A: Store in tightly sealed containers under cool, dry conditions away from direct sunlight and strong oxidizers. It is hygroscopic and should be protected from prolonged exposure to humid environments to maintain optimal quality and clarity.
