What is Polysorbate 60 Used For?

Polysorbate 60 is a common food additive approved by the FDA as generally recognized as safe (GRAS), and is also extensively used in cosmetics and pharmaceuticals. This versatile emulsifier and stabilizer plays a critical role in blending immiscible ingredients like oil and water to ensure product consistency and texture.

Quick Summary

Polysorbate 60 functions as a versatile emulsifier, stabilizer, and surfactant in numerous products. It prevents oil and water from separating in food, creates smooth textures in cosmetics like lotions and creams, and helps stabilize active ingredients in pharmaceuticals.

Key Points

• Emulsifying Agent: Polysorbate 60 is primarily used to blend and stabilize oil-in-water mixtures, preventing ingredients from separating.

• Food Industry Stabilizer: In food production, it enhances texture, increases volume in baked goods, and prevents ice crystal formation in frozen desserts.

• Cosmetic Formulation Aid: It ensures creams, lotions, and makeup have a smooth, consistent texture and helps solubilize fragrances in water-based products.

• Pharmaceutical Excipient: It assists in stabilizing and dissolving active drug ingredients in medications, especially liquid suspensions and ointments.

• Regarded as Safe: Polysorbate 60 is approved by the FDA as Generally Recognized as Safe (GRAS) for specified food uses.

• Not for Organic Products: Its synthetic production process means it is not allowed in certified organic cosmetics.

• Potential for Irritation: While generally mild, high concentrations can cause skin irritation in some sensitive individuals.

What Exactly is Polysorbate 60?

Polysorbate 60, also known as E435 or Tween 60, is a synthetic compound derived from natural sources. It functions as a non-ionic surfactant, reducing surface tension between different substances. It is created by reacting sorbitol with stearic acid and ethylene oxide, giving it properties that interact with both water and fat, making it an effective emulsifier. Polysorbate 60 is typically a yellowish, oily liquid or waxy solid that dissolves easily in water.

Polysorbate 60 in the Food Industry

Polysorbate 60 is a common food additive used to improve product quality and shelf life, primarily acting as an emulsifier and stabilizer. For key applications in food, cosmetics, and other industries, including a comparison table of Polysorbate 60 vs. Polysorbate 80, refer to {Link: foodadditives.net https://foodadditives.net/emulsifiers/polysorbate-60/}. Polysorbate 60 is approved by the FDA and EFSA and generally considered safe for cosmetic and food use at recommended levels. The Cosmetic Ingredient Review (CIR) Expert Panel has evaluated its safety for cosmetic use.

However, some points to consider include:

• Skin Sensitivity: High concentrations or use on sensitive skin may cause mild irritation or allergic reactions. Patch testing is advised.
• Gastrointestinal Effects: Excessive consumption might lead to discomfort like nausea or diarrhea, particularly for those with digestive issues.
• Organic Certification: The synthetic production process means it is not allowed in certified organic cosmetic products.

Conclusion

Polysorbate 60 is a widely used ingredient in food, cosmetics, and pharmaceuticals due to its effectiveness as an emulsifier, stabilizer, and surfactant. It is crucial for blending oil and water-based ingredients, ensuring product consistency and quality across various applications. With a generally recognized safety profile, it remains a popular choice for manufacturers, though awareness of potential sensitivity is recommended. For comprehensive safety data, consult scientific assessments like the Cosmetic Ingredient Review report.

Frequently Asked Questions

Is polysorbate 60 safe to eat?

Yes, polysorbate 60 is considered safe to eat and is approved as a food additive by the U.S. FDA and European Food Safety Authority. However, consuming it in very large quantities may cause gastrointestinal discomfort, especially for those with digestive sensitivities.

What is the difference between polysorbate 60 and polysorbate 80?

The main difference is the fatty acid used in their creation; polysorbate 60 is made with stearic acid, while polysorbate 80 is made with oleic acid. This results in polysorbate 80 having stronger solubilizing properties for oils and being liquid at room temperature, while polysorbate 60 is a waxy solid or semi-gel.

Can I use polysorbate 60 in homemade cosmetics?

Yes, polysorbate 60 is a popular and effective emulsifier for homemade cosmetics, particularly for making creams, lotions, and cleansers. It is non-comedogenic and mild, but you should always perform a patch test, especially if you have sensitive skin.

Why is polysorbate 60 added to ice cream?

In ice cream, polysorbate 60 is added as a stabilizer and emulsifier to prevent the growth of large, gritty ice crystals. This process helps create a smoother, creamier texture and improves the overall mouthfeel of the product.

Does polysorbate 60 affect the foam in shampoos?

Yes, as a non-ionic surfactant, polysorbate 60 can help enhance the foaming properties and thicken formulations like shampoos and body washes. This contributes to better cleansing performance and a richer lather.

Is polysorbate 60 derived from a natural source?

Polysorbate 60 is considered semi-synthetic. It is produced by a chemical process called ethoxylation, which uses natural-source ingredients like sorbitol and stearic acid to create the final compound.

Can polysorbate 60 cause an allergic reaction?

While generally well-tolerated, polysorbate 60 can cause mild skin irritation or allergic reactions in sensitive individuals, particularly at higher concentrations. Patch testing is recommended to check for personal sensitivity.

What is the purpose of polysorbate 60 in pharmaceuticals?

In pharmaceuticals, polysorbate 60 acts as an excipient to stabilize drug formulations and solubilize active ingredients that are not easily dissolved in water. This helps ensure consistent dosing and effectiveness in oral suspensions and ointments.
