Chlorinated Paraffins are complex mixtures of chlorinated n-alkanes used as secondary plasticizers, flame-retardant additives, extreme-pressure lubricant additives, metalworking fluid additives, sealant additives, rubber additives, coating additives, and specialty industrial formulation components.
Chlorinated Paraffins are generally classified by carbon-chain length as short-chain chlorinated paraffins, medium-chain chlorinated paraffins, and long-chain chlorinated paraffins, and their performance depends on carbon number, chlorine content, viscosity, color, thermal stability, volatility, compatibility, and regulatory status.
Chlorinated Paraffins are typically supplied as colorless to pale yellow viscous liquids, pastes, or waxy solids depending on grade, and Chlorinated Paraffins require careful regulatory review because short-chain chlorinated paraffins are heavily restricted and medium-chain chlorinated paraffins are also under increasing regulatory scrutiny in several markets.

DESCRIPTION
Chlorinated Paraffins are complex mixtures of chlorinated straight-chain alkanes produced by chlorinating paraffin hydrocarbons to different chlorine contents.
Chlorinated Paraffins are not single molecules, and each commercial grade contains many homologues and isomers with different carbon-chain lengths and degrees of chlorination.
Chlorinated Paraffins are commonly grouped as SCCP, MCCP, and LCCP according to carbon-chain range, and this grouping strongly affects performance, viscosity, volatility, environmental behavior, and regulatory treatment.
Chlorinated Paraffins function as secondary plasticizers by increasing flexibility and reducing hardness in compatible polymer systems.
Chlorinated Paraffins function as flame-retardant contributors because chlorine-containing additives can interfere with combustion chemistry and increase halogen content in the formulation.
Chlorinated Paraffins function as extreme-pressure lubricant additives because chlorinated hydrocarbons can form protective boundary films on metal surfaces under high-pressure metalworking conditions.
Chlorinated Paraffins require careful product selection because shorter-chain and higher-chlorine grades can differ significantly from longer-chain grades in toxicity, persistence, bioaccumulation, volatility, and regulatory acceptability.
Chlorinated Paraffins should be evaluated against current chemical regulations because SCCPs are widely restricted and MCCP/LCCP substances may be subject to evolving risk assessment, authorization, or restriction requirements.
Chlorinated Paraffins should be used according to supplier recommendations, workplace safety standards, environmental controls, end-use regulations, and customer compliance requirements.

FIRST AID
Inhalation:
Move to fresh air if vapors, mist, aerosol, or decomposition fumes are inhaled.
Seek medical attention if coughing, headache, dizziness, respiratory irritation, or breathing discomfort occurs.
Avoid further exposure until ventilation and vapor or mist controls are confirmed.
Skin Contact:
Remove contaminated clothing and wash skin thoroughly with soap and water.
Seek medical advice if irritation, redness, dryness, or prolonged discomfort develops.
Wash contaminated clothing before reuse.
Eye Contact:
Rinse cautiously with water for at least 15 minutes.
Remove contact lenses if present and easy to do, then continue rinsing.
Seek medical attention if irritation, pain, or blurred vision persists.
Ingestion:
Rinse mouth with water and do not induce vomiting.
Seek medical attention or contact a poison center if swallowed.
Never give anything by mouth to an unconscious person.
Note to Physicians:
Treat symptomatically.
Monitor for irritation, gastrointestinal discomfort, aspiration risk, and possible effects from chlorinated hydrocarbon exposure after significant exposure.
Provide supportive care as needed.
HANDLING AND STORAGE
Handling:
Use appropriate PPE including chemical-resistant gloves, safety glasses, and protective clothing for bulk handling.
Avoid breathing vapors, mist, aerosol, or fumes from heated material.
Use clean, dry equipment to prevent contamination and maintain consistent plasticizer or additive performance.
Ventilation:
Use general ventilation for normal handling.
Use local exhaust ventilation where mist, aerosol, heated vapor, or decomposition fumes may be generated.
Provide adequate ventilation during heating, blending, filling, metalworking-fluid preparation, and large-scale transfer operations.
Storage:
Store in tightly closed containers in a cool, dry, well-ventilated area.
Protect from excessive heat, direct sunlight, contamination, and incompatible chemicals.
Keep away from strong oxidizers, strong bases, reactive metals, and high-temperature conditions that may cause decomposition.
Spill and Leak Procedures:
Contain spill with inert absorbent and prevent entry into drains, soil, and waterways.
Collect into suitable chemical waste containers for recovery or disposal according to local regulations.
Clean remaining oily residue carefully because Chlorinated Paraffins can create slippery surfaces and persistent contamination.
Handling Precautions:
Confirm regulatory status before use because Chlorinated Paraffins are divided into SCCP, MCCP, and LCCP categories with different restrictions and risk profiles.
Control heating because Chlorinated Paraffins may decompose under severe heat and release corrosive hydrogen chloride fumes.
Rotate stock using FIFO practices to maintain consistent color, viscosity, acidity, chlorine content, thermal stability, and formulation performance.
