Table of Contents

Sorbitan tristearate (abbreviation STS), also called Span 65. Sorbitan tristearate is known to be used in some chocolates as a substitute to trans-fatty acids. It is also a polysorbate which is commonly found in cosmetic preparations and food items as an emulsifier. Trans fat is made by hydrogenation of vegetable oil in the presence of a catalyst. Hydrogenation changes the arrangement of hydrogen atoms in vegetable oils which causes the formation of trans fats and diglycerides. Polysorbate 60 (a) E613 and (b) E472 are usually taken from coconut oil while sorbitan monostearate is produced using a chemical reaction on sorbitan fatty acid ester with heat.

What is sorbitan tristearate?

Sorbitan tristearate is an emulsifier and surfactant and it is used in cosmetics as a thickening agent, emulsifier and stabilizer. It is also used as a food additive to thicken, stabilize and emulsify foods.

Sorbitan tristearate is a mixture of sorbitol esters of stearic acid with three molecules of fatty acid attached to each molecule of sorbitol. It has the appearance of white waxy solid at room temperature and melts above 30°C to a clear liquid that does not cloud at 25°C.( 1)

Polyoxyethylene sorbitan tristearate

Polyoxyethylene sorbitan tristearate, also known as POE-20 sorbitan tristearate and Tween 20, is a nonionic surfactant used in cosmetics and personal care products to emulsify and stabilize products.

Polyoxyethylene sorbitan tristearate is a white to cream-colored solid or viscous liquid. It is miscible with water and has low order with other solvents. It has an HLB value of 9.0–10.0 which means that it is highly soluble in water and can be used as a surfactant for cleaning agents or shampoos.

Polyethylene glycol sorbitan tristearate (or PEG-ST, also known as Tween 60), is a synthetic, nonionic surfactant used for its emulsifying properties in cosmetics, pharmaceuticals, and personal care products. It is composed of polyoxyethylene polyoxypropylene block copolymers, with the polyoxypropylene blocks alternating with the polyoxyethylene blocks.

What is sorbitan tristearate made from?

Sorbitan tristearate is a nonionic surfactant made from sorbitol, stearic acid, and oleic acid. It is used as an emulsifying agent in cosmetics and beauty products, as well as in food manufacturing.

It is also used in the production of polyurethane foams to improve their stability and reduce water absorption.

How is sorbitan tristearate made?

Similar to sorbitan monostearate, this ingredient is also derived from direct esterification of sorbitol with stearic acid, but it differs from the former because it features three stearic acid molecules attached to the sorbitan molecule.

There is no pure compound in the final product, but a mixture of partial esters of sorbitol and its anhydrides with edible stearic acid.

Stearic acid

First, stearic acid is produced from stearin, which comes from vegetable fat or animal tallow (fat). This reaction occurs when the stearin has been melted and then cooled down again.

Sorbitol

Next, sorbitan must be added to the mix. This substance comes from sorbitol, which is a sugar alcohol found in plants and fruits like apples and pears. A chemical reaction takes place between sorbitol and stearic acid to produce sorbitan tristearate powder.

Spray drying

Finally, the resulting powder needs to undergo spray drying in order for it to become usable in products such as lotions and creams.

What is sorbitan tristearate used for?

A combination of sorbitan tristearate and polysorbates can enhance the stabilization of oil in water (O/W) emulsions. Sorbitan tristearate is used as a water-in oil emulsifier. A variation in the Span/Polysorbate ratio can result in emulsifying systems with different HLB values.

Sorbitan tristearate is an emulsifier and surfactant used in the food industry. It is also used in cosmetics, personal care products, and pharmaceuticals. Sorbitan tristearate uses include:

Sorbitan tristearate in food

Sorbitan tristearate has very good water-holding properties and is used in powdered beverages to improve the mouthfeel of the product. It can also be used to make chocolate smoother and creamier. It’s also used in frozen desserts, chewing gum and bakery products.

Sorbitan tristearate in chocolate

Chocolate formulations often use sorbitan tristearate and lecithin as emulsifiers to retard fat bloom in chocolate. ( 2)

Chocolate contains sorbitan tristearate, which adjusts sugar crystallization and appearance as well as reduces stickiness.

By preventing β’ crystals from converting to β crystals under excessive temperatures, sorbitan tristearate retards fat bloom by creating an emulsifier to prevent β crystals from migrating to the chocolate surface and causing fat bloom.

Additionally, it results in a negative impact on the appearance of the chocolate.

In the making of chocolate, cocoa powder, an important ingredient, forms unstable crystals that are called β’ crystals.
