The Polysorbate family of non-ionic surfactants, including Polysorbate 20, Polysorbate 60, and Polysorbate 80, are workhorses in the formulation industry. Each offers unique properties, primarily dictated by their fatty acid component, which influences their Hydrophilic-Lipophilic Balance (HLB) and thus their suitability for different applications. For formulators and procurement managers, understanding these differences is key to achieving optimal product performance. NINGBO INNO PHARMCHEM CO.,LTD. provides these essential ingredients and guidance to help you make informed purchasing decisions.

Understanding HLB Values: The Key to Emulsifier Selection

The HLB system is a crucial tool for selecting emulsifiers. It quantifies the degree to which a surfactant is hydrophilic (water-loving) or lipophilic (oil-loving). Generally:

  • HLB 3-6: W/O (water-in-oil) emulsifiers
  • HLB 7-9: Wetting agents
  • HLB 8-18: O/W (oil-in-water) emulsifiers
  • HLB 13-16: Detergents, solubilizers

Polysorbate 20 (HLB ~16.7): Derived from lauric acid, Polysorbate 20 is highly hydrophilic. It's an excellent solubilizer and detergent, commonly used in cosmetics for products like shampoos and body washes to help disperse fragrances and oils. In pharmaceuticals, it can be used to solubilize poorly soluble drugs.

Polysorbate 60 (HLB ~14.9): Formed with stearic acid, Polysorbate 60 is also a strong O/W emulsifier and stabilizer. It's particularly favored in food applications for baked goods and ice cream, as well as in cosmetics for lotions and creams where a stable emulsion with a pleasant texture is required. Its intermediate HLB makes it versatile.

Polysorbate 80 (HLB ~15.0): With oleic acid as its fatty acid component, Polysorbate 80 is another effective O/W emulsifier and solubilizer. It is widely used in food (e.g., ice cream, salad dressings), cosmetics, and pharmaceuticals, often for its ability to stabilize lipid-based drug delivery systems and improve the solubility of hydrophobic compounds.

Making Your Purchase Decision:

When you need to buy Polysorbate 60, consider its specific role in your formulation. If you require a strong O/W emulsifier with good stabilizing properties for applications involving stearic acid derivatives (like many food and cosmetic creams), Polysorbate 60 is an excellent choice. If your formulation demands superior oil solubilization or is based on unsaturated lipids, Polysorbate 80 might be more suitable. For detergent or high solubilization needs in cosmetics, Polysorbate 20 could be the answer.
