Applications

 

Tween-20 is a nonionic surfactant and emulsifier derived from sorbitol and lauric acid. 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 Sciences

A. Protein Research & Immunoassays

• ELISA/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 Biology

• Prevents enzyme adsorption in PCR tubes (reduces false negatives).

• Used in DNA/RNA extraction buffers.

 

2. Pharmaceuticals & Drug Delivery

• Solubilizing Agent:

  • Enhances solubility of hydrophobic drugs (e.g., vaccines, injectables).

• Emulsion Stabilizer:

  • In topical creams and ointments (e.g., corticosteroid formulations).

 

3. Cosmetics & Personal Care

• Emulsifier:

  • 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 Uses

• Cleaning Products:

  • Degreaser in industrial cleaners (e.g., lab equipment sanitization).

• Textile & Leather Processing:

  • Disperses dyes evenly.

 

Key Properties

• Low 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 Concentrations

Application	Concentration Range
Immunoassays	0.05-0.1%
Cell Lysis	0.1-1%
Drug Formulations	0.1-5%
Cosmetics	0.5-2%

 

Safety & Handling

• Biodegradable 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.
