As a professional manufacturer and supplier of food additives, we understand the importance of quality, efficiency, and stability in the food industry. Throughout our collaborations with customers, we’ve encountered many common questions about Polysorbate 80 or Tween 80. In this blog, we’ve compiled some of the most frequently asked questions and provided detailed answers to help you use Tween 80 with confidence in your food production processes.

1. Does Food-grade Polysorbate 80 have Organic Certification or Claims?

Generally, food-grade Polysorbate 80 (Tween 80 ) does not have organic certification. It is a synthetic compound made from sorbitol and fatty acids. To obtain organic certification, raw materials must meet organic farming standards, so Polysorbate 80 is not typically classified as an organic product. If you need an organic emulsifier, other plant-based alternatives may be more suitable.

2. What is the Proportion of Sorbitan Monooleate in Polysorbate 80?

Polysorbate 80 is composed of Sorbitan Monooleate (Span 80) and Polyoxyethylene (PEG). Sorbitan typically makes up 60%-80% of the composition, with the remaining part being the polyethylene glycol (PEG) portion. This combination provides the emulsifying properties of Tween 80.

3. What are the Temperature and Pressure Conditions for Using Polysorbate 80?

The optimal temperature for dissolving Polysorbate 80 is typically in the range of 40°C to 70°C to ensure it dissolves properly and performs its emulsifying function effectively. In most food applications, normal pressure is sufficient unless a specific manufacturing process requires higher pressure. For typical food formulations, no high-pressure conditions are required.

4. What is the Density of Polysorbate 80/Sorbitan Monooleate (Span 80) ?

The density of Tween 80 is approximately 1.06 g/cm³. This value may vary slightly with temperature, but it generally remains around this range. Sorbitan Monooleate (Span 80), as a primary component of Tween 80, also has a similar density of around 1.04–1.06 g/cm³.

5. What is the Viscosity of Polysorbate 80/Sorbitan Monooleate (Span 80)?

The viscosity of Tween 80 at room temperature (20°C) is typically 300-800, which means it is quite viscous in its concentrated form. The viscosity will decrease as the temperature increases. When heated to around 60°C or higher, the viscosity of Tween 80 decreases significantly, becoming more fluid. The viscosity of Span 80 is similar.

6. What is the Production Method of Polysorbate 80?

The production method for Tween 80 involves two main steps:
Synthesis of Sorbitan Esters: Sorbitol is reacted with fatty acids, such as oleic acid (from castor oil), to form Sorbitan Monooleate (SPAN 80).
Polyoxyethyleneation: SPAN 80 is then reacted with ethylene oxide (EO) to produce Polyoxyethylene Sorbitan Monooleate, forming Polysorbate 80.
Purification: The product undergoes filtration, refining, and drying to remove impurities and ensure food-grade quality.

7. What is the HLB Value of Polysorbate 80?

The HLB (Hydrophilic-Lipophilic Balance) value of Polysorbate 80 is approximately 15, indicating that it is a highly hydrophilic (water-loving) emulsifier. This makes it suitable for forming oil-in-water (O/W) emulsions, where water is the continuous phase.

8. What Regulations and Standards does Polysorbate 80 Comply with?

Polysorbate 80 complies with the following regulations:
FDA (U.S.): In the United States, Tween 80 is approved for use in food products under 21 CFR 172.854.
EFSA (EU): In the European Union, Tween 80 is approved as food additive E433 by the European Food Safety Authority (EFSA).

9. What is the Composition of Polysorbate 80?

The main components of Polysorbate 80 are:
Sorbitan Monooleate (SPAN 80): Approximately 60%-80%.
Polyoxyethylene (20) Sorbitan Monooleate: Around 20%-40%.

This composition allows Tween 80 to act effectively as an emulsifier and stabilizer, providing smooth textures and preventing phase separation in food products.

10. Does Polysorbate 80 Contain Gluten in its Raw Materials?

No, Polysorbate 80 does not contain gluten. The potential for gluten in Tween 80 depends on the source of the oleic acid used in its production. If oleic acid is derived from rice oil, there could be a small risk of gluten contamination. However, the oleic acid used by CHEMSINO is not sourced from rice oil, meaning our Tween 80 does not contain gluten in its raw materials. Therefore, there is no gluten risk in the Polysorbate 80 we supply.

Conclusion

Polysorbate 80 is an essential emulsifier that plays a crucial role in enhancing the texture, stability, and shelf life of food products. Whether you’re looking to improve product consistency, prevent separation, or extend the shelf life of your food, Polysorbate 80 emulsifier offers a reliable solution.
