Polysorbate 80 Manufacturer & Supplier in India
Rishit Polysurf LLP manufactures and supplies Polysorbate 80 (Tween 80) from our specialty chemicals facility in GIDC Dholka, Ahmedabad, Gujarat — supplying pharmaceutical, cosmetic, food, and industrial formulators across India and export markets with a consistent, well-documented nonionic emulsifier.
Product Overview - What is Polysorbate 80?
Polysorbate 80 — also sold under the trade name Tween 80, and known chemically as polyoxyethylene sorbitan monooleate — is a nonionic surfactant and emulsifier produced by reacting sorbitan monooleate with approximately 20 moles of ethylene oxide. It carries CAS Number 9005-65-6, an average molecular weight of about 1,310 g/mol, and a typical HLB value of around 15 — placing it among the higher-HLB polysorbates and making it well suited to oil-in-water emulsification.
Because it carries no ionic charge, Polysorbate 80 stays functional across a wide pH range and combines readily with anionic, cationic, and amphoteric surfactants in the same system. It's used primarily as a solubilizer, emulsifier, wetting agent, and suspension stabilizer.
Key Benefits
- Excellent Emulsification — stabilizes oil-in-water systems across a broad range of oil phases.
- High-HLB Surfactant — HLB ≈ 15 supports strong oil-in-water performance.
- Consistent Stability — performs reliably across storage and formulation conditions within its recommended range.
- Well-Established Safety Profile — long-standing use across pharmaceutical, food, and cosmetic industries within regulatory guidelines.
- Broad Compatibility — blends well with anionic, cationic, amphoteric, and other nonionic surfactants.
- Effective Oil Solubilizer — disperses essential oils, fragrance oils, and other hydrophobic actives into aqueous systems.
- Stable Across a Wide pH Range — nonionic structure means performance doesn't collapse outside a narrow pH window.
- Cross-Industry Versatility — one grade, multiple formulation categories: pharma, cosmetics, food, and industrial.

Core Applications
1. Agrochemical Formulations
Polysorbate 80's oleic-acid backbone gives it stronger affinity for oily and solvent-based systems than shorter-chain polysorbates, which is why it's commonly selected to emulsify the oil or solvent phase in emulsifiable concentrate (EC) formulations for insecticides, fungicides, and herbicides — helping the carrier oil disperse evenly into spray-tank water at field dilution. It also performs well in oil-based adjuvants and crop-oil concentrates, where its emulsifying action helps the spray solution spread and hold on the leaf surface rather than bead off.
2. Cosmetics
In cosmetic and personal care formulations, Polysorbate 80 solubilizes and emulsifies oil components — fragrance oils, essential oils, and active ingredients — into creams, lotions, face washes, cleansers, and hair-care products, producing clear to translucent aqueous systems without an oily residue.
3. Industrial
Beyond pharma, cosmetics, and food, Polysorbate 80's high-HLB, oil-in-water emulsifying behavior is useful across industrial cleaners and degreasers, textile-processing auxiliaries, agrochemical emulsifiable-concentrate formulations, and other specialty-chemical systems that need a stable, water-soluble nonionic component.
4. Food & Pharmaceuticals
Recognized in food applications under food-additive number E433, Polysorbate 80 is used for emulsifying and stabilizing formulated food products. Please confirm regulatory status and permitted levels for your specific market.
In pharmaceutical formulation, Polysorbate 80 (Tween 80) acts as a solubilizer, emulsifier, and suspension stabilizer for oral liquid formulations. For injectable or vaccine-formulation applications requiring pharmacopeial compliance for parenteral use, please contact our technical team to confirm batch-specific documentation.

Frequently Asked Questions
Polysorbate 80 is a nonionic surfactant and emulsifier, chemically known as polyoxyethylene sorbitan monooleate (CAS 9005-65-6). It's produced by ethoxylating sorbitan monooleate with about 20 moles of ethylene oxide and is widely known by its original trade name, Tween 80.
It's used as a solubilizer, emulsifier, wetting agent, and suspension stabilizer — for example, in oral liquid pharmaceutical formulations, creams and lotions, food emulsification (E433), and industrial cleaning, textile, and agrochemical formulations.
Yes. Tween 80 is the original trade name for Polysorbate 80. Both refer to the same chemical — CAS 9005-65-6, polyoxyethylene sorbitan monooleate — and the terms are used interchangeably in technical literature.
Yes. It carries no ionic charge, which is why it remains functional across a broad pH range and generally combines well with anionic, cationic, and amphoteric surfactants in the same system.
Polysorbate 80 has a typical HLB value of approximately 15, which is why it's generally used for oil-in-water emulsification rather than water-in-oil systems.
9005-65-6. Its molecular formula is C₆₄H₁₂₄O₂₆, with an average molecular weight of about 1,310 g/mol.
It's widely used as a general pharmaceutical excipient — a solubilizer, emulsifier, and suspension stabilizer in oral liquid formulations. Injectable and vaccine-grade use carries stricter purity, testing, and regulatory requirements; contact our technical team to confirm what compliance documentation is available for your required batch before specifying it for parenteral use.
Polysorbate 80 is recognized under food-additive number E433 for emulsifying and stabilizing applications. Approved uses and permitted levels vary by country and food category, so confirm current regulatory status for your specific market and application.
Yes. We provide a Certificate of Analysis and Material Safety Data Sheet (MSDS/SDS) for Polysorbate 80 shipments — request the batch-specific COA at the time of order for shipment-level verification.
Yes to both. Contact our technical sales team with your intended application and required quantity, and we can arrange a sample for evaluation as well as discuss bulk/drum packaging options.
