A Complete Guide to Food Grade Polysorbate 80

Date:2024-07-15

Read:

Food grade Polysorbate 80 is a common non-ionic surfactant and emulsifier widely used in the food industry. In this blog post, we primarily introduce food-grade Polysorbate 80 and its various applications.

What is Food Grade Polysorbate 80?

Food Grade Polysorbate 80 (E433) also known as polyoxyethylene (20) sorbitan monooleate, is a synthetic emulsifier used extensively in the food industry. It is a non-ionic surfactant and emulsifier derived from the polyethoxylation of sorbitan (a derivative of sorbitol) and oleic acid, a fatty acid.

It appears as a viscous, amber-colored liquid with a mild characteristic odor and a slightly bitter taste. Polysorbate 80 emulsifier is soluble in water, ethanol, methanol, and ethyl acetate, but insoluble in mineral oil. It has a chemical formula of C64H124O26 and a molecular weight of approximately 1310 g/mol. With a hydrophilic-lipophilic balance (HLB) of around 15, it is highly hydrophilic and effective in forming oil-in-water emulsions.

How is Polysorbate 80 Different from the Other Polysorbates?

Polysorbates, like Polysorbate 20, Polysorbate 40, Polysorbate 60, and Polysorbate 80, are categorized by the type of fatty acid chain they contain, indicated by the number.
Here's a breakdown and the difference of each:

Fatty Acid Composition:

Polysorbate 80: Derived from oleic acid, also known as polyoxyethylene (20) sorbitan monooleate.
Other Polysorbates:
Polysorbate 20: Derived from lauric acid, also known as polyoxyethylene (20) sorbitan monolaurate.
Polysorbate 40: Derived from palmitic acid, also known as
polyoxyethylene (20) sorbitan monopalmitate
Polysorbate 60: Derived from stearic acid, also known as polyoxyethylene (20) sorbitan monostearate.
The "20" refers to the number of oxyethylene groups on the molecule, and the different fatty acid chains affect their suitability for various applications.
The type of fatty acid affects the hydrophilic-lipophilic balance (HLB) and the overall behavior of the surfactant.

Hydrophilic-Lipophilic Balance (HLB):

Polysorbate 80: Has an HLB value of around 15, making it highly hydrophilic and suitable for forming oil-in-water emulsions.
Other Polysorbates:
Polysorbate 20: HLB value around 16.7.
Polysorbate 40: HLB value around 15.6.
Polysorbate 60: HLB value around 14.9.

Why is Polysorbate 80 Added to Foods?

1. Ice Cream

Polysorbate 80 food grade plays a crucial role in ice cream by preventing the formation of ice crystals and maintaining an ideal texture. It achieves this by effectively emulsifying the fat and water components of the ice cream mixture. This ensures that the ice cream remains smooth and creamy throughout storage and consumption, enhancing the overall sensory experience for consumers.

2. Baked Goods

In baked goods such as cakes, cookies, and pastries, Polysorbate 80 for sale serves to enhance both the volume and texture of the final products. As a dough conditioner, it improves the consistency of the dough by promoting an even distribution of fats and other ingredients. This results in baked goods that are softer, more uniform in texture, and visually appealing.

3. Salad Dressings

Polysorbate 80 emulsifier is used in salad dressings to maintain a stable emulsion between oil and vinegar. By preventing separation, it ensures that the dressing maintains a consistent texture and appearance. This enhances the usability and appeal of the salad dressing, providing consumers with a smooth and well-blended dressing for salads and other dishes.

4. Sauces and Gravies

In sauces and gravies, Polysorbate 80 e433 acts as an emulsifier and stabilizer, ensuring a uniform texture and preventing the ingredients from separating. This property is essential for maintaining the integrity of sauces and gravies during cooking, serving, and storage, thereby enhancing the overall quality and consistency of dishes.

Polysorbate 80 Uses in Cosmetics and Pharmaceutical Industries

Besides its applications in the food industry, Polysorbate 80 for sale is widely used in the cosmetics and pharmaceutical industries.

Cosmetics Industry:

Polysorbate 80 as Emulsifier and Stabilizer: Used to blend water-soluble and oil-soluble ingredients, ensuring product stability and texture in formulations like lotions, creams, and certain cosmetics.
Polysorbate 80 as Surfactant: Found in cleansing products such as shampoos, body washes, and facial cleansers to help remove oils and dirt from skin and hair effectively.
Polysorbate 80 as Solubilizer: Enables the incorporation of fragrances, essential oils, and other hydrophobic substances into water-based cosmetics, ensuring even distribution and enhanced fragrance delivery.

Pharmaceutical Industry:

Drug Formulations: Polysorbate 80 e433 is an emulsifier and stabilizer in liquid and semi-solid drug formulations, ensuring uniform dispersion of active ingredients in products like oral liquids, ointments, and emulsions.
Injection Formulations: Polysorbate 80 is used in some injectable medications to dissolve drugs and maintain stability, ensuring efficacy and safety during administration.
Medical Device Lubricant: Polysorbate 80 e433 reduces friction and prevents adhesion on medical devices, improving operational efficiency and safety during surgical and treatment procedures.
