What is an E-liquid?
E-liquid, referred to as e-juice or e-fluid, is the liquid component in e-cigarettes that creates vapor upon heating. It commonly includes nicotine and flavorings blended in a base of propylene glycol (PG) and vegetable glycerin (VG) at different ratios.
Why is it important to monitor the quality control parameters of E-liquids?
Monitoring the quality control parameters of e-liquids is important because regulations require manufacturers to disclose detailed ingredient information, including exact quantities. Additionally, depending on the market, ingredients must meet pharmaceutical or food-grade certification standards to ensure product safety and compliance of E-Liquids.
How to ensure the quality control for E-Liquids?
Quality control of e-liquids relies on several analytical methods, where measuring refractive index and density plays a crucial role in assessing the concentrations of propylene glycol (PG) and vegetable glycerin (VG). This allows manufacturers to maintain product quality and tailor flavor, strength, and vapor production to deliver an optimal experience for consumers.
