Polysorbates: Chemical ID, CAS, Formula, HS Code Database

Product Identification

Property	Detail	Manufacturer Technical Commentary
Product Name	Polysorbates	This term covers a family of non-ionic surfactants derived from the esterification of sorbitan with fatty acids, followed by ethoxylation. The main commercial grades include Polysorbate 20, Polysorbate 40, Polysorbate 60, and Polysorbate 80. Functional differences depend on the type and degree of fatty acid substitution as well as the number of ethylene oxide units, which directly influences solubility, emulsification performance, and compatibility in formulations.
IUPAC Name	Polyoxyethylene (20) sorbitan monolaurate (Polysorbate 20) Polyoxyethylene (20) sorbitan monopalmitate (Polysorbate 40) Polyoxyethylene (20) sorbitan monostearate (Polysorbate 60) Polyoxyethylene (20) sorbitan monooleate (Polysorbate 80)	In production batches, actual ethoxylation levels may vary by source and process route, which is confirmed by detailed analysis during QC release. The molecular species profile is influenced by fatty acid source and ethoxylate chain distribution, both monitored as key batch consistency parameters.
Chemical Formula	Typical empirical formula for major grades: Polysorbate 20: C58H114O26 Polysorbate 40: C62H122O26 Polysorbate 60: C64H126O26 Polysorbate 80: C64H124O26	Actual formulation depends on the fatty acid chain incorporated. Stoichiometry for ethoxylated groups and sorbitan backbone often shows grade-dependent variability and is not typically uniform across production lots from different process routes. QC release involves confirmation of molecular weight distribution and possible presence of residual fatty acid or by-product esters.
Synonyms & Trade Names	Tween 20, Tween 40, Tween 60, Tween 80 Polyoxyethylene sorbitan fatty acid ester E432 (Polysorbate 20), E433 (Polysorbate 80) (Food Additive Numbers)	The use of synonym or trade names in specifications and certifications is regulated by local labeling and regulatory requirements. Product labeling for export or sensitive markets usually specifies both the INCI or food additive code and the proprietary trade name, with batch-level traceability maintained by internal tracking.
HS Code & Customs Classification	Main HS Code: 340213 (This covers non-ionic organic surface-active agents)	For customs documentation, the main heading is established under Chapter 34 for non-ionic surfactants. Actual classification may differ at the subheading level depending on region and specific use declaration (industrial processing, food additive, or pharma ingredient). Clear segregation by HS code is necessary during export documentation and pre-shipment inspection to avoid compliance issues at border control. Some regions require certification to verify the absence of animal-derived residues or other restricted materials, which must be managed per lot.

Production Observations

The main raw materials include sorbitan, ethylene oxide, and selected fatty acids, sourced based on physical purity and compliance with downstream grade requirements (food, pharma, or industrial). Deviating from preferred grades during fatty acid selection results in product batches with altered HLB values, cloud points, or appearance, impacting final customer compliance. The ethoxylation step requires precise control of reaction conditions to avoid excess polyoxyethylene by-products or unreacted intermediates. In-process monitoring is maintained through batch sample withdrawal and chromatography. Batches with off-spec color, odor, or turbidity are segregated for rework or downgraded specification.

Application Sensitivity

Polysorbate functional differences manifest strongly in formulation: higher grades of purity (for parenteral or ophthalmic uses) demand lower levels of residual reactants, organic impurities, and color bodies. Technical and industrial applications have wider specification tolerances but still require predictable emulsification and wetting properties. Shelf-life and storage risk vary; non-uniform batches show greater risk of phase separation or increased peroxide values over time. Downstream processability for pharmaceutical and food production is dependent on narrow control of fatty acid profile and residual polyoxyethylene content, with purification strategies applied accordingly.

Technical Properties, Manufacturing Process & Safety Guidelines: Polysorbates

Physical & Chemical Properties

Physical State & Appearance

Polysorbates generally arrive as viscous liquids or semi-solid pastes at room temperature, depending on the specific ester type and fatty acid source. Color ranges from pale yellow to amber, and slight characteristic odors may arise from the raw fatty acid composition. Lower-melting grades flow at room temperature, while certain variants with longer or more saturated fatty acid chains solidify at lower temperatures. Melting points vary with composition; typical industrial grades display a broad softening range instead of discrete melting. Boiling points are undefined due to decomposition before actual boiling. Density depends on both fatty chain length and ethoxylation degree, with most grades falling between the densities of oils and light pastes.

Chemical Stability & Reactivity

In production, polysorbates show good chemical resistance under neutral and slightly acidic conditions but may hydrolyze in strongly acidic or alkaline environments. Hydrolysis or oxidation risks increase under elevated temperature, UV exposure, or in the presence of oxidizing agents. Stability varies across grades; higher unsaturation in fatty acids increases risk of peroxide formation during storage.

Solubility & Solution Preparation

Polysorbates function as nonionic surfactants and dissolve readily in water, alcohols, and some glycols. Degree of solubility depends on the specific polysorbate (e.g., Polysorbate 20 vs. Polysorbate 80), HLB value, and the presence of electrolytes in the medium. Drying or clumping during storage complicates aqueous solution preparation. For consistent performance, process lines recommend pre-mixing and gradual addition to agitated tanks to avoid local over-concentration.

Technical Specifications & Quality Parameters

Specification Table by Grade

Parameter	Typical Range (Grade-Dependent)	Notes
Appearance	Viscous liquid to semi-solid	Differs by chain composition and storage temperature
Acid Value	Grade-specific	Key impurity control; impacts performance in sensitive formulations
Saponification Value	Grade-specific	Varies with raw fatty acid input
Water Content	Quality-controlled	Water content can affect shelf life and microbial resistance
Heavy Metals	Minimized, within regulatory limits	Testing required for food/pharma grades

Impurity Profile & Limits

A detailed impurity profile considers unreacted fatty acids, monoesters, polyols, residual ethylene oxide (if applicable), and peroxide values. Limits for each impurity depend on final application and grade certification—food, cosmetic, and pharmaceutical grades are subject to more stringent profiles for oxidative and process residuals.

Test Methods & Standards

Each lot undergoes verification based on industry reference techniques, including acid-base titration (acid value), saponification value assessment, water determination (Karl Fischer or thermogravimetric), and instrumental analyses such as GC or HPLC for impurity and residual tracking. Specifications reference compendia (such as USP/NF, Ph.Eur., or local equivalents) according to customer or regulatory demand. Final release standards can differ by customer, region, and use.

Preparation Methods & Manufacturing Process

Raw Materials & Sourcing

Production begins with sorbitol (plant-derived, high-purity), ethylene oxide (or alternative alkoxylation agent), and fatty acids mainly from vegetable sources. Raw material variability in fatty acid chain composition or unsaturation directly impacts product performance; thus, sourcing strategies prioritize consistent supply with minimal seasonal variation. Traceability and sustainability certifications often required for food and pharmaceutical applications.

Synthesis Route & Reaction Mechanism

The manufacturing process follows esterification of sorbitol or its anhydrides with selected fatty acids, then controlled ethoxylation. Parameters such as reaction temperature, catalyst selection (typically acid or base), and feedstock purity directly affect the distribution of mono-, di-, and polyesters as well as byproduct levels. Route selection considers processing efficiency, product quality, and minimization of hazardous intermediates.

Process Control & Purification

Continuous control over feed rates, reaction temperature, and pressure helps avoid side reactions and limits formation of colored or volatile byproducts. Post-synthesis purification often involves multi-stage filtration and vacuum stripping to remove unreacted components and volatile impurities. Process lines are designed to minimize oxygen ingress to limit peroxide formation.

Quality Control & Batch Release

Each batch sequence includes in-process controls (pH, color, clarity, esterification degree) and post-process identity and purity testing. Product release requires conformity to internal specifications and, where relevant, pharmacopeial standards or customer-defined criteria. Lab retains reference samples for traceability and reproducibility checks.

Chemical Reactions & Modification Potential

Typical Reactions

Polysorbates resist most non-oxidative chemical attacks. They undergo hydrolysis under strong acid/base. Industrial interests focus on hydrogenation for altering stability or esterification degree adjustment for modifying HLB. Mild oxidation or peroxide formation remains a primary degradation mechanism to monitor.

Reaction Conditions (Catalyst, Temperature, Solvent)

Manufacturing proceeds under elevated temperatures and, depending on the reaction phase, either acid or base catalysis. Precise temperature and catalyst loading depend on the fatty acid and sorbitol batch profile. Solvent-free routes are favored to limit residuals.

Derivatives & Downstream Products

Polysorbates serve as intermediates in functional emulsifiers, solubilizers, and stabilizers for cosmetics, foods, and pharmaceutical formulations. Downstream utilization leverages their high HLB values and compatibility across a range of pH and ionic strengths. Custom modifications incorporate different alkoxylation patterns or fatty acid chains to adjust properties.

Storage & Shelf Life

Storage Conditions

Bulk storage tanks and packaging areas regulate temperature to minimize viscosity changes and separation. High unsaturation grades require exclusion of oxygen and light to mitigate peroxide risk; inert gas overlays and opaque containers are routine for sensitive lots. Relative humidity in storage space is controlled to prevent water uptake and clustering.

Container Compatibility

Product contact materials must resist softening, leaching, or permeation—high-density polyethylene and epoxy-lined drums achieve this. Metal containers, unless lined, may catalyze peroxide or impurity formation.

Shelf Life & Degradation Signs

Shelf life remains variant by application and grade; primary degradation manifests as discoloration, thickening, odor development, or increase in acid and peroxide values. Storage inspections monitor these markers; lots beyond stability windows undergo requalification or disposal.

Safety & Toxicity Profile

GHS Classification

Classification depends on polysorbate type and application requirement. Industrial technical grades often carry no mandatory hazard classification for acute toxicity but may require warning symbols if residuals (e.g., ethylene oxide, heavy metals) approach regulatory cut-offs for restricted applications.

Hazard & Precautionary Statements

Prolonged skin exposure can cause irritation, especially with higher residual fatty acids or peroxides. Eye contact produces irritation requiring rinse and removal from exposure.

Toxicity Data

Long experience supports low acute oral and dermal toxicity for major grades when used in accordance with intended applications. Acceptable intake limits and route-specific risk assessments rely on established toxicological studies, as summarized by regulatory agencies for food and pharma certifications. Any deviation from purification or batch QA protocols can introduce higher-risk residuals, emphasizing strict batch control.

Exposure Limits & Handling

Workplace limits for polysorbates are generally not defined except for specific residuals. Dusting risk is minimal compared to powder-type surfactants. Designated PPE protects against long-term exposure in production and bulk handling. Good ventilation ensures control of trace volatile byproducts during high-throughput or heated transfers.

Supply Capacity & Commercial Terms for Polysorbates

Production Capacity & Availability

Polysorbate output depends on core raw material inventories and batch run schedules. Production lines handle multiple grades, shifting between polysorbate 20, 40, 60, and 80 as guided by market priorities and confirmed orders. Since batch consistency and cross-contamination avoidance require rigorous cleaning protocols, switching often incurs downtime. Supply reliability for high-purity, pharma, or food grades hinges on both upstream sorbitol and oleic acid supply chain stability. Large-volume availability often fluctuates more as prioritized customers book capacity ahead by up to 2-3 quarters—especially for specialized applications such as biologics or injectable formulations.

Lead Time & MOQ

Lead time reflects grade, packaging size, and order volume. For pharmaceutical or GMP-compliant polysorbates, routine lead time may stretch beyond 8-12 weeks if validation batches or full regulatory filings are needed. Industrial and feed grades move faster, typically from existing warehouse stocks. Minimum order quantities differ by packaging, process train batch size, and customer history. Bulk shipments (IBC or drum) are scheduled according to consolidated production planning. Project-based MOQ often aligns with reactor scale or validated lot increments, especially in regulated markets.

Packaging Options

Standard packaging includes fiber drums, HDPE or steel drums, and intermediate bulk containers. HDPE drums suit pharma and food grades to avoid leaching or contamination, while steel drums fit industrial use where chemical compatibility is not limited by downstream concern. For customers with high traceability requirements, every batch receives tamper-evident seals and full chain-of-custody documentation.

Shipping & Payment Terms

Export logistics are planned based on route stability and seasonal constraints, such as temperature excursions in intercontinental containers. Certain grades demand reefer containers or insulated transport, guided by downstream stability studies or pharma regulatory expectations. Payment terms depend on customer credit risk, annual contract volume, and territory. Long-standing buyers in mature economies may access 30-60-day terms; new or high-risk buyers adhere strictly to pre-shipment or L/C payment.

Pricing Structure & Influencing Factors

Raw Material Cost Composition

Polysorbate pricing starts with the market price of sorbitol (or ethoxylated sorbitan) and vegetable fatty acids, especially oleic acid. The ethoxylation cost can shift based on region, tied closely to feedstock-grade ethylene oxide volatility. Many grades require excipient or food purity, so purification costs sharply increase for tight peroxide value and residual solvent control. Costs multiply with cGMP production or full traceability documentation, along with specialized packaging.

Fluctuation Causes

Raw material swings drive most price moves. The vegetable oils market impacts upstream fatty acids, and weather-related supply disruptions or regulatory changes in palm or coconut producing nations cascade directly into finished polysorbate cost structure. Regulatory changes in EU/US on allowable impurity levels or approved sources can spike demand for compliant batches, causing spot shortages and forward contract premiums.

Product Price Difference Explanation: Grade, Purity, and Certification

Pharma and injectable grades command the highest prices—batch traceability, validated allergen status, and low peroxide benchmarks raise direct processing and compliance costs. Lower-grade, technical-use polysorbates lack these controls and are priced close to raw material index plus simplified process economics. Specialized food, kosher, halal, or allergen-free claims add cost layers, mainly from additional documentation and process segregation rather than pure material difference. Certified packaging like UN-approved drums or serialized pharma bags factors into premium grade costings.

Global Market Analysis & Price Trends

Application Fields & Grade Selection Guide for Polysorbates

Application Fields & Grade Matching Guide

Industry Applications

Polysorbates serve as non-ionic surfactants for a range of industries where emulsification, solubilization, or dispersion is a process requirement. In pharmaceutical and biotechnological formulations, they function as solubilizers and stabilizers for actives susceptible to aggregation. Food processing employs polysorbates to improve texture and dispersion of fats, particularly in bakery fats and frozen desserts. Industrial coatings, inks, and agrochemicals also demand grades with consistent hydrophilic-lipophilic balance for reliable dispersion and wetting. Cosmetic and personal care products often require grades characterized by odor and color control for clear lotions and creams.

Grade-to-Application Mapping

How to Select the Right Grade

Step 1: Define Application

Production teams match grades based on stated application—injectable, oral, topical, food process, or non-consumer exposure. End use governs which batch control documentation is required and determines testing needs for physical, chemical, and microbiological purity.

Step 2: Identify Regulatory Requirements

Trace regulatory standards for each customer region. A batch may clear domestic food codes but require separate documentation for exports to different zones due to diverging impurity and analytical test lists controlled by regional authorities.

Step 3: Evaluate Purity Needs

Discuss with customers the real risk factors for their application. If a polysorbate will be exposed to high temperatures or sensitive actives, production departments recommend tighter peroxide and unsaturation specifications, and prioritize lots with full traceability on raw material lot release and impurity profile.

Step 4: Consider Volume & Budget

Batch route selection often depends on customer’s project volume. For lower-value industrial uses, technical grades are batched for cost efficiency, with less intensive purification. Pharmaceutical and regulated food customers, even at lower volumes, expect ongoing process documentation, which impacts cost structure and scheduling.

Step 5: Request Sample for Validation

The most robust way to match performance is by validating a product grade on actual application-scale runs. Technical support provides samples along with batch-specific analytical data and assists in root-cause analysis if performance deviates from expectations. Quality and R&D track returned feedback for continuous improvement and batch-to-batch consistency management.
