Polysorbate 60

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:

  • Emulsifying
  • Surfactant

    Safety Profile:

· General Assessment: Considered a safe ingredient with low skin irritation potential. It is non-toxic and non-comedogenic.

· Regulatory Status: Classified as Generally Recognized as Safe (GRAS) by the U.S. Food and Drug Administration (FDA) for use in food.
