Polysorbate 28

Polysorbate 28, a high-efficiency non-ionic surfactant and emulsifier. It consists of sorbitan monolaurate ethoxylated with approximately 80 moles of ethylene oxide. s Polysorbate 28/PEG-80 Sorbitan Laurate is used in mild, low irritation cleaners, body washes, baby shampoo, and more

Key Characteristics

• Chemical Identity: Also known as PEG-80 Sorbitan Laurate.
• Properties: It is a water-soluble, yellow liquid. Its high ethoxylation gives it a high HLB (Hydrophile-Lipophile Balance) value of 19.2, making it exceptionally effective as an oil-in-water (O/W) emulsifier and solubilizer.
• Compatibility: As a non-ionic surfactant, it is compatible with both anionic and cationic surfactants.

Common Applications

Polysorbate 28 is primarily used for its extreme mildness and stability-enhancing properties:

• Personal Care: It is a staple in “tear-free” baby shampoos and sensitive skin cleansers because it reduces the irritation potential of other surfactants.
• Cosmetics: Used as a stabilizer for lotions and creams, and as a solubilizer for fragrances and essential oils in water-based formulations.
• Industrial: Employed as a wetting agent, dispersant, and industrial lubricant.
