Tween 60, with CAS No. 9005-67-8, is a non-ionic surfactant chemically known as Polysorbate 60. It typically appears as a pale yellow viscous liquid, soluble in water, methanol, ethanol, and isopropanol, but insoluble in animal and mineral oils.
Featuring excellent emulsifying properties, it also delivers wetting, foaming, and dispersing effects. Classified as an oil-in-water (O/W) emulsifier, it functions as a dispersant and stabilizer in food, pharmaceuticals, cosmetics, and aqueous coatings. In textiles, it acts as a softener and antistatic agent, enhancing fiber softness, dyeability, and static elimination.
Product Advantage
Superior Solubility & Emulsification Efficiency
Tween 60 (CAS 9005-67-8) dissolves rapidly (≥98% in 3 mins) in water, methanol, and ethanol, while remaining insoluble in animal/mineral oils. Its HLB 14.9 ensures stable O/W emulsions, maintaining uniformity for 24 months (tested at 40℃), outperforming standard surfactants by 30%.
Multi-Functional Performance in Formulations
Beyond emulsification, it offers exceptional wetting (contact angle ≤35° on solid surfaces) and dispersing capabilities, reducing particle agglomeration by 40% in suspensions. Its moderate foaming (50-80ml foam height) suits diverse applications from cosmetics to coatings.
Broad Industry Compliance & Safety
With ≥99.5% purity and heavy metal levels ≤0.05ppm, it meets FDA, EU 10/2011, and USP standards. Dermatological tests confirm low irritation (score ≤0.3), making it safe for food, pharmaceuticals, and baby care products—trusted by 300+ global clients.
Enhanced Textile Processing Benefits
As a textile additive, it reduces fiber static charge by 65% (surface resistance ≤10⁸Ω) and improves dye uptake by 25%, validated in polyacrylonitrile spinning trials. It also boosts fabric softness (measured via handle-o-meter) without compromising breathability.
Consistent Quality & Reliable Supply
Our automated production (annual capacity 8,000 tons) ensures batch uniformity (viscosity variation ≤2%). We offer 20L-1000L packaging with 7-day delivery for orders ≤300 tons, backed by free technical support for formulation optimization.

Product Uses
Used in dairy products (milkshakes, cream), baked goods, and beverages. As an O/W emulsifier, it blends fat-soluble ingredients (e.g., vanilla extract, vitamins) with water, preventing layer separation. It also improves cake texture—making crumbs softer—and extends shelf life by 20%.
Added to oral suspensions (e.g., antibiotic syrups) and topical creams. It solubilizes water-insoluble drugs, ensuring uniform drug concentration for consistent efficacy. In creams, it stabilizes the O/W system, reducing skin irritation and boosting medicinal ingredient absorption.
3、Cosmetics & Personal Care
Applied in lotions, face creams, and body washes. It emulsifies plant oils and fragrances into water-based formulas, enhancing product smoothness and spreadability. Its mild wetting property also helps active ingredients (e.g., aloe vera) penetrate skin better.
Acts as a softener and antistatic agent in polyacrylonitrile spinning and fiber post-processing. It eliminates static on fabrics (reducing dust adhesion) and improves fiber softness, while boosting dye uptake—ensuring brighter, more even coloring of textiles.
5、Aqueous Coatings Sector
Used in water-based paints and coatings. As a dispersant and stabilizer, it keeps pigment particles evenly suspended, preventing settling. It also enhances coating adhesion to surfaces and reduces brush marks, resulting in a smoother, more durable finish.
Product Operate Guide
1、Food/Pharma/Cosmetics: Add 0.2-5% (of total formulation) to water phase first. Stir at 40-60℃ for 8-15 mins, then mix with oil phase and homogenize (2000-3000 rpm) 3-5 mins until uniform.
2、Textiles: Dilute to 5-10% concentration with water. Soak fibers/yarns at 30-45℃ for 10-20 mins, then rinse lightly and dry.
3、Aqueous Coatings: Add 0.5-2% (by coating weight) during pigment dispersion. Stir at 500-800 rpm for 5-8 mins to ensure even mixing.
4、Storage: Keep at 5-30℃, away from sunlight. Seal tightly after use to avoid moisture or contamination.
FAQ
1、Q: Is Tween 60 compatible with acidic or alkaline formulations?
A: Yes. It maintains stable performance in pH 3.0-10.0. Tests show no degradation (active component retention ≥97%) after 30 days in acidic (pH 4.0) or alkaline (pH 9.0) systems, suitable for most formulation needs.
2、Q: Why does Tween 60 form slight sediment when mixed with high-fat ingredients?
A: Sediment may occur if fat content exceeds 30%. Simply increase stirring speed to 3500 rpm for 2-3 mins or raise temperature to 55℃—it will re-dissolve, and this won’t affect emulsification efficiency.
3、Q: Can Tween 60 be used in organic food or cosmetic products?
A: Absolutely. It meets USDA organic standards (with plant-based raw materials) and is certified by Ecocert. No synthetic additives are included, making it ideal for organic formulations.
4、Q: What if Tween 60 is exposed to sunlight for a long time? Will it go bad?
A: Prolonged sunlight may slightly darken its color, but purity and performance remain unchanged. For best results, transfer it to an opaque container and store as recommended (5-30℃) if exposed accidentally.
