Name: Ethoxylated Castor Oil Synonyms: Polyoxyethylene Castor Oil Appearance: Pale yellow to amber liquid with a mild odor Common Uses: Emulsifier in pharmaceuticals, personal care products, textile processing, and agricultural chemicals Chemical Structure: Derivative of castor oil modified with ethylene oxide, which changes its solubility in water and behavior in mixtures CAS Number: 61791-12-6 Solubility: Disperses in water, soluble in organic solvents
Potential Health Effects: May cause mild irritation to the skin, eyes, or respiratory tract on prolonged or repeated contact Physical Hazards: Not highly flammable but can burn if exposed to fire GHS Label Elements: May lack acute toxicity labels but carelessness in storage or use can amplify risk Environmental Risk: Spillages can impact aquatic life due to emulsification properties, raising concerns in water treatment or fish habitats
Main Ingredient: Ethoxylated Castor Oil (percentage of ethoxylation can vary depending on supplier and grade) Impurities: Trace amounts of unreacted castor oil, byproducts from ethoxylation process Additives: Sometimes blended with stabilizers or preservatives, though not always disclosed
Skin Contact: Wash exposed area with soap and water to remove residues; monitor for rash or irritation Eye Contact: Rinse gently with water for several minutes; seek attention if redness or stinging lingers Inhalation: Move outdoors to fresh air for easier breathing if vapor or mist causes light-headedness or coughing Ingestion: Do not induce vomiting; rinse mouth with water and contact medical personnel if a large amount is swallowed General Advice: Allergic reactions are rare but possible for individuals sensitive to castor derivatives
Suitable Extinguishing Agents: Use foam, dry chemical, or carbon dioxide for small fires; water spray for larger incidents Hazardous Combustion Products: May release smoke, carbon oxides, and other decomposition products when burned Firefighter Protection: Wear complete personal protective gear including breathing apparatus to avoid inhaling vapors or fumes Flammability: Does not easily catch fire but can sustain burning once ignited
Personal Precautions: Use gloves, goggles, and protective clothing to avoid prolonged contact Spill Containment: Prevent liquid from spreading to drains or open water bodies using absorbent materials like sand or earth Cleaning Up: Collect spilled liquid for proper disposal; thoroughly wash contaminated area with water and detergent Environmental Protection: Block runoff paths to surface waters and take quick action to report larger spills
Handling: Work in well-ventilated spaces to keep fumes from building up; use proper tools and avoid splashing Storage Conditions: Store in tightly capped containers, protected from heat, open flames, and direct sunlight Incompatibilities: Keep away from strong oxidizers or acids that can provoke dangerous reactions Special Advice: Regular checks for leaks or container damage help avoid problems later on
Engineering Controls: Use exhaust fans or ventilation hoods in spaces with regular mixing and pouring Personal Protection: Wear chemical-resistant gloves, splash-proof goggles, and long sleeves to limit exposure Occupational Exposure Limits: Regulatory exposure limits are not always set, demanding personal caution and monitoring for symptoms Hygiene Practices: Wash hands and arms thoroughly before eating or touching your face; launder work clothing separately
Appearance: Clear to slightly hazy yellowish liquid Odor: Characteristically mild or fatty pH: Near neutral in solution Boiling and Melting Points: High boiling point, usually above 200°C; does not freeze easily Density: Ranges typically from 1.0 to 1.1 g/cm³ Viscosity: Flows easily at room temperature but thickens as temperatures drop Solubility: Forms stable emulsions with water and dissolves well in alcohols and glycols
Chemical Stability: Remains stable under typical storage and use conditions Reactivity: Resists breakdown unless exposed to strong oxidizing agents Hazardous Reactions: Burning or overheating can generate fumes and off-gassing Materials to Avoid: Strong acids, alkalis, and peroxides Conditions to Avoid: Prolonged direct heat, sunlight, and contamination with incompatible substances
Acute Toxicity: Low oral and dermal toxicity; ingestion of large quantities may trigger gastrointestinal symptoms Irritation and Sensitization: Occasional cases of mild skin or eye irritation, but serious allergic reactions remain rare Long-term Exposure: Evidence so far does not link repeated handling to chronic health effects for most people Inhalation Risks: Vapors or mists from heated material can cause coughing or mild respiratory discomfort Special Populations: Those with a castor oil allergy are advised to avoid handling
Environmental Fate: Biodegradable in soil and water but can affect aquatic environments by changing surface tension and oxygen uptake Aquatic Toxicity: Harmful to aquatic organisms above certain concentrations, especially if a large spill enters streams or ponds Persistence: Does not linger in the environment under normal conditions, breaks down into natural substances over time Bioaccumulation: Unlikely to accumulate in fish or wildlife since oily components degrade
Waste Treatment: Collect any unused or contaminated product and hand it over to waste management sites equipped to handle chemicals Incineration: Controlled burning in approved facilities offers safe disposal for large quantities Sewer Disposal: Avoid washing substantial amounts into drains since emulsifiers disrupt wastewater treatment and harm aquatic ecosystems Packaging: Rinse empty containers before recycling or discarding, and never reuse containers for food or drink
Regulatory Status: Generally shipped without strict hazardous goods restrictions Packing Requirements: Sturdy, leak-proof drums or containers required for shipping long distances Transport Hazards: Spilled material on roadways makes surfaces slippery and can seep into stormwater systems Shipping Advice: Label containers clearly, watch for leaks, and report major spills to authorities during transit
Global Classification: Regulations on ethoxylated castor oil differ by region but it often appears on lists of substances permitted for use in cosmetics, pharmaceuticals, and food under relevant safety conditions Reporting Obligations: Large users or manufacturers may need to track and record usage and disposal as required by national chemical laws Worker Protection: Guidelines on protective gear and safe handling practices appear in most workplace safety regulations involving chemical agents
