Tag: Polysorbate 80
Insights on food emulsifiers—applications, functions, and benefits to improve stability, texture, and quality across industries.
Polysorbate 80 (Tween 80, E433) stands as a cornerstone non-ionic surfactant in B2B formulations, enabling stable oil-in-water (O/W) emulsions across food, pharmaceuticals, and cosmetics industries. With its high HLB value of 15.0, it excels in solubilizing hydrophobic actives, enhancing texture, and ensuring product stability, making it indispensable for high-performance applications like ice cream overrun control and vaccine stabilization.
Technical Profile and Applications
Derived from polyethoxylated sorbitan and oleic acid, Polysorbate 80 offers superior emulsification, wetting, and dispersion properties. It is water-soluble, vegan-certified (plant-based oleic acid sources), gluten-free, and compliant with Halal/Kosher standards. Key specifications include: viscosity of 300–500 mPa·s at 25°C, density 1.08 g/cm³, and GRAS status by FDA (21 CFR 172.840) with ADI 0–25 mg/kg bw per EFSA.
Food & Beverage: Prevents fat coalescence in ice cream (0.1–0.2% dosage), stabilizes condiments and brines for uniform flavor dispersion.
Pharma/Biotech: Solubilizes APIs in injectables and stabilizes protein formulations.
Cosmetics: Emulsifies oils in cleansers and shampoos, improving spreadability and scalp cleansing.
Unlike Polysorbate 60 (HLB 14.9, saturated chains), its unsaturated oleic acid chain provides better liquidity for liquid systems.
