Common Name: Tween 60 / Polyoxyethylene (20) sorbitan monostearate
CAS Number: —
EINECS Number: —
Molecular Formula: —
Molecular Weight: —
Polysorbate 60 (Tween 60) is a nonionic surfactant produced by ethoxylating sorbitan monostearate. It is commonly used as an emulsifier and stabilizer in creams, lotions, food emulsions and pharmaceutical preparations. Polysorbate 60 delivers good emulsification performance for medium- to high-viscosity systems and helps provide smooth, stable textures in topical and oral formulations.
Molecular structure description
Hydrophilic part: Polyoxyethylene (4) sorbitan head group
HLB value: ~9.6 (moderately lipophilic, suitable for water-in-oil emulsions or co-emulsifier use)
Specifications
It is a nonionic surfactant composed of polyoxyethylene (20) sorbitan esterified with stearic acid, yielding a hydrophilic molecule effective in reducing surface tension and forming stable emulsions.
It is soluble in water, ethanol, and ethyl acetate; slightly soluble in vegetable oils; and insoluble in mineral oil.
When dispersed in water, it forms clear to slightly hazy solutions. Its excellent emulsifying and stabilizing properties make it suitable for creams, lotions, and food emulsions.

Applications
It is especially effective in oil-in-water emulsions containing saturated fats and solid fats.
Its ability to provide creamy textures and stable emulsions makes it ideal for creams, lotions, and whipped toppings.
Emulsification Efficiency – Stable W/O Emulsions
Sorbitan esters are highly effective in forming stable water-in-oil emulsions. Ideal for margarine, creams, and ointments, they help maintain consistency and prevent separation over time.
Mild & Skin-Friendly – Ideal for Cosmetics
Widely used in lotions, creams, and makeup products, sorbitan esters are non-irritating and suitable for sensitive skin. They provide smooth textures and enhance product stability.
Food Grade & Safe – Emulsifiers for Processing
Approved for food use, they act as emulsifiers in sauces, dairy products, and spreads. Improve mouthfeel, extend shelf life, and maintain homogeneity of processed foods.
Pharmaceutical Use – Enhances Drug Stability
Used in medicinal creams, gels, and suspensions, sorbitan esters help deliver oil-soluble actives effectively. They improve bioavailability and ensure long-term formulation stability.
