E432 - Polyoxyethylen-sorbitanmonolaurat

Origin

Polyoxyethylene sorbitan monolaurate, also known as Polysorbate 20, is a nonionic surfactant and emulsifier derived from sorbitan monolaurate, which is ethoxylated with approximately 20 moles of ethylene oxide. Sorbitan monolaurate itself is derived from sorbitol (a sugar alcohol) and lauric acid (a saturated fatty acid commonly found in coconut and palm kernel oil). The ethoxylation process increases the hydrophilicity of the molecule, making it more soluble in water.

Usage

E432 is widely used in the food industry as an emulsifier, stabilizer, and dispersing agent. It helps to blend oil and water-based ingredients, preventing separation and maintaining a consistent texture. It is commonly found in baked goods, ice cream, salad dressings, and processed foods. In non-food applications, it is used in cosmetics, pharmaceuticals, and detergents. The typical usage levels in food range from 0.1% to 1% depending on the application.

Side Effects

Polysorbate 20 is generally considered safe for consumption at the levels typically used in food. The Joint FAO/WHO Expert Committee on Food Additives (JECFA) has established an Acceptable Daily Intake (ADI) of 0-25 mg/kg body weight for polysorbates (including E432, E433, E434, E435, and E436) combined. Some individuals may experience mild gastrointestinal discomfort, such as bloating or diarrhea, if consumed in large quantities. Allergic reactions are rare but possible. Some studies have raised concerns about potential contamination with ethylene oxide and 1,4-dioxane during the manufacturing process, but regulatory agencies set limits to minimize these risks.

Regulatory Status

E432 is approved for use as a food additive in many countries, including the European Union, the United States, and Canada. In the EU, it is subject to specific purity criteria and labeling requirements. In the United States, it is regulated by the Food and Drug Administration (FDA) under specific sections of the Code of Federal Regulations (CFR).
