E436 – Polyoxyethylene sorbitan tristearate
StabiliserDescription
Mixture of esters of sorbitol, sorbitan, and isosorbide with stearic acid, ethoxylated with approximately 20 moles of ethylene oxide
Notes
Polysorbate 65 is a synthetic emulsifier created by combining sorbitol (a sugar alcohol derived from corn or wheat) with stearic acid (a fatty acid typically obtained from palm oil or other vegetable sources). The manufacturing process involves treating these ingredients with ethylene oxide, which creates long molecular chains that have both water-loving and oil-loving properties. This additive works as an emulsifier, meaning it helps oil and water mix together smoothly and stay combined. You'll commonly find polysorbate 65 in baked goods like cakes and cookies, ice cream, whipped toppings, and some processed foods where a smooth, stable texture is important. It prevents ingredients from separating and helps create that consistent mouthfeel we expect from these products. While polysorbate 65 is synthetically produced, it's made from ingredients that can originate from plant sources. It's generally considered suitable for vegetarian and vegan diets, though those following strict religious dietary laws may want to verify the source of the stearic acid used. The additive is approved for use in many countries and is considered safe when used within regulated limits, though some people prefer to limit synthetic additives in their diet.
