What is SORBITAN TRISTEARATE？

SORBITAN TRISTEARATE is a non-ionic surfactant widely used as an emulsifier and stabilizer. It is a triester of sorbitan (a dehydrated sorbitol derivative) and stearic acid. Classified as a lipophilic (oil-loving) emulsifier with a low HLB (Hydrophile-Lipophile Balance) value, it is particularly effective in stabilizing water-in-oil (W/O) emulsions. This compound is valued for its excellent lubricating properties and ability to control crystallization in fats. It is a common ingredient approved for use in food, cosmetic, and industrial applications due to its non-toxic and biodegradable nature.

Application:

1.Food Industry:

Used as an emulsifier and stabilizer in baked goods, cakes, whipped toppings, coffee creamers, and edible oils to prevent spattering and improve texture. (Complies with FDA and EU regulations for food additives, often referred to as E492).

2.Cosmetics & Personal Care:

Acts as a key W/O emulsifier, co-emulsifier, and opacifying agent in creams, lotions, makeup, and hair care products. It provides a smooth, non-greasy feel and enhances product stability.

3.Industrial Applications:

Functions as an emulsifier in synthetic fibers, metalworking fluids, and industrial lubricants. It is also used as an anti-static agent and lubricant in plastic processing.

4.Pharmaceuticals:

Employed as an emulsifying agent in the formulation of topical ointments and creams.

5. Paints & Coatings: Used as a dispersing agent and flow control additive.

How it works

Sorbitan tristearate is a nonionic surfactant that helps blend ingredients that would normally separate, like oil and water.

It forms a three-dimensional network within products that traps fat particles, improving stability and resistance to temperature changes.

Safety profile:

SORBITAN TRISTEARATE is generally recognized as safe (GRAS) for use in food by the FDA and is approved as a food additive (E492) in the EU. It is considered non-irritating to the skin and non-sensitizing, making it suitable for cosmetic formulations. It is biodegradable and presents minimal environmental concerns.

Storage requirements:

keep the product dry

relative humidity < 50%

protect product against influences of weather and contamination

Transport & Packaging:

SORBITAN TRISTEARATE for technical applications is solely supplied in packaging of different sizes . It can be packaged in various items: 25 kg bags, 1000 kg bags.
