E435 — Polyoxyethylene (20) Sorbitan Monostearate (Polysorbate 60)

Polyoxyethylene (20) sorbitan monostearate, commonly known as Polysorbate 60 or Tween 60, is a synthetic compound used primarily as an emulsifier and stabilizer in various products. It is produced by reacting sorbitol with stearic acid and ethylene oxide. 

Danger Level: 0 — Safe

Purpose in Products

Polysorbate 60 serves several functions:

  • Emulsifier: Facilitates the mixing of oil and water phases in products like sauces and dressings.
  • Stabilizer: Maintains the consistency and texture of emulsions, preventing separation.

Health Considerations

Polysorbate 60 is generally considered safe for consumption. However, individuals intolerant to propylene glycol should avoid it. Some people may experience allergic skin reactions, such as eczema. 

Impact on Children

Polysorbate 60 is safe for children when consumed in typical dietary amounts.

Impact on Taste

Polysorbate 60 is tasteless and odorless, making it an ideal ingredient for various food products without altering their flavor profiles.

Compatibility with Other Additives

Polysorbate 60 is compatible with various other food additives, including sugars and other hydrocolloids. Its water-binding properties make it suitable for use in products requiring moisture retention.

Natural Occurrence

Polysorbate 60 is a synthetic compound and does not occur naturally.

Alternatives and Substitutes

For those seeking alternatives to Polysorbate 60, options include:

  • Polysorbate 80 (E433): A widely used emulsifier in food products.
  • Lecithin (E322): A natural emulsifier derived from soybeans or egg yolks.

Regulation

Polysorbate 60 is approved for use as a food additive in many countries, including the European Union, where it is designated as E435. Regulatory bodies such as the European Food Safety Authority (EFSA) have evaluated its safety and concluded that it poses no health concerns when used within established limits. 

Conclusion

Polysorbate 60 (E435) is a versatile and safe food additive used primarily as an emulsifier and stabilizer. While generally safe, individuals with specific sensitivities should exercise caution.
