SORBITAN TRISTEARATE
Sorbitan Tristearate (E492) is used as an emulsifier and stabilizer in bakery products, toppings, and coatings, fat emulsions, milk and cream analogs, beverage whiteners, edible ices, desserts, sugar confectionery including chocolate, emulsified sauces, dietary food supplements, chewing gum, and dietetic foods.
Sorbitan Tristearate is used mainly in chocolates to maintain color and shine and prevent blooming and in margarine and cooking oils to maintain an appealing texture.
As a food additive, it has the E number E492.
CAS no.: 26658-19-5
EC / List no.: 247-891-4
Sorbitan Tristearate is produced by esterifying sorbitol with commercial stearic acid derived from food fats and oils.
Sorbitan Tristearate is a mixture of the partial esters of sorbitol and its mono- and dianhydride with edible stearic acid.
Sorbitan Tristearate is an effective emulsifier to retard fat bloom in chocolate.
Sorbitan tristearate and lecithin are often used as surface-active substances to reduce viscosity in chocolate formulations.
In chocolate, sorbitan tristearate adjusts sugar crystallization and appearance, and it can reduce stickiness.
Sorbitan Tristearate is used as a crystal inhibitor in margarine, low-fat spreads, palm olein, and coconut oil.
PERSONAL CARE Application of Sorbitan Tristearate:
Sorbitan Tristearate can also be used in various personal care products, including skin care products, skin cleansing products, moisturizers, eye makeup, and other makeup.
Sorbitan tristearate functions as a surfactant in cosmetics and personal care products.
Its concentrations typically range between 0.1% and 5% (up to 10%).
Sorbitan tristearate may be present in the following products:
Skincare products
Makeup products
Moisturizers
Sorbitan tristearate is used as a water-in-oil (W/O) emulsifier, and when combined with polysorbates, it can stabilize oil-in-water (O/W) emulsions.
The Span/Polysorbate ratio formulation can produce emulsifying systems with various HLB values.
