Its hydrophilic-lipophilic balance (HLB ~16.7) makes it widely used in biotechnology, pharmaceuticals, cosmetics, and industrial processes. Below are its key applications: 1. Biotechnology & Life SciencesA. Protein Research & ImmunoassaysELISA/Western Blotting:Blocks non-specific binding in membranes (e.g., 0.05-0.1% in TBST buffer).Stabilizes antibodies and proteins in solution.Cell Lysis:Mild detergent for membrane protein extraction (0.1-1% concentration).B. PCR & Molecular BiologyPrevents enzyme adsorption in PCR tubes (reduces false negatives).Used in DNA/RNA extraction buffers. 2. Pharmaceuticals & Drug DeliverySolubilizing Agent:Enhances solubility of hydrophobic drugs (e.g., vaccines, injectables).Emulsion Stabilizer:In topical creams and ointments (e.g., corticosteroid formulations). 3. Cosmetics & Personal CareEmulsifier:Combines oil/water phases in lotions, shampoos, and cleansers.Foam Stabilizer:Improves lather in mild facial cleansers. 4. Food Industry (Limited Use)Emulsifier (E432):Approved for ice creams, baked goods (typically <0.5% concentration). 5. Industrial & Household UsesCleaning Products:Degreaser in industrial cleaners (e.g., lab equipment sanitization).Textile & Leather Processing:Disperses dyes evenly. Key PropertiesLow toxicity (safe for topical/biological use).Water-soluble, forms micelles above critical concentration (CMC ~0.06 mM).Compatible with most buffers (avoid strong oxidizers). Typical ConcentrationsApplicationConcentration RangeImmunoassays0.05-0.1%Cell Lysis0.1-1%Drug Formulations0.1-5%Cosmetics0.5-2% Safety & HandlingBiodegradable but may irritate eyes at high concentrations.Storage: Stable at RT; avoid prolonged exposure to light/heat.Note: Tween-20 is often compared to Tween-80 (oleate ester), which has higher lipid solubility.
