Sorbitan tristearat, also known as E492, is a food additive and emulsifier commonly used in the food and cosmetics industries. It is derived from sorbitol and stearic acid, and its molecular formula is C60H114O82. It appears as a creamy or waxy solid and is insoluble in water but can emulsify in oils and solvents2.

In food, it is used to stabilize emulsions, such as in margarine, chocolate, and baked goods. In cosmetics, it serves as a dispersing agent and stabilizer in creams and lotions3. While generally considered safe within regulated limits, excessive consumption may lead to health concerns, such as liver issues or gastrointestinal irritation.

Sorbitan tristearat (E492) is known by several other names, including:

• STS (abbreviation for Sorbitan Tristearate)

• Span 65

• Sorbitan trioctadecanoate

• Anhydrosorbitan tristearate

• Sorbitan esters of fatty acids

CAS Nr: 26658-19-5

E492, also known as Sorbitan Tristearate, is a versatile food additive. Here are some key points about it:

• Chemical Nature: It is a mixture of partial esters of sorbitol and vegetable stearic acid.

• Appearance: Creamy yellowish bead solids with a slight characteristic smell.

• Solubility: It is not soluble in water, methanol, or ethanol.

Uses:

• Emulsifier: Helps blend oil and water, preventing separation in products like dressings and sauces.

• Stabilizer: Maintains the texture and appearance of food products, such as preventing fat bloom in chocolate.

• Texture Improvement: Enhances the texture of baked goods and ice cream by improving fat distribution and preventing large ice crystals.

Safety: Generally recognized as safe (GRAS) by regulatory agencies worldwide, but should be used in appropriate amounts.
