CAS Number:
9005-67-8
Chemical Formula:
C64H126O26
Other Common Names:
Tween 60, Polyoxyethylene (20) Sorbitan Monostearate
Description:
Polysorbate 60 is an emulsifier and surfactant commonly used in cosmetics to blend water and oil-based ingredients.It enhances the stability, texture, and consistency of formulations by preventing ingredient separation.
Uses:
It is widely utilized as an emulsifier and solubilizer in personal care products and food.
· Cosmetics & Personal Care: Primarily used in creams, lotions, makeup, shampoos, and conditioners. It ensures stable blending of oil and water-based ingredients, creates a smooth texture, and helps solubilize fragrances and essential oils into water-based products.
· Food Industry: Approved for use as an emulsifier, stabilizer, and thickener in items like baked goods, frozen desserts (e.g., ice cream), and whipped toppings.
Origin:
Polysorbate 60 is a synthetic (semi-synthetic) ingredient. It is produced through the ethoxylation of sorbitol (derived from sources like corn syrup), followed by reaction with a fatty acid, primarily stearic acid.
What does POLYSORBATE 60 do in a formulation?
Its primary functions are:
