Dicyclohexyl Phthalate / DCHP CAS 84-61-7

1. Dicyclohexyl phthalate is primarily used as a plasticizer for PVC, acrylic resins, polystyrene, and nitrocellulose, improving flexibility and processability while providing a smooth surface finish .
2. DCHP CAS 84-61-7 serves as a waterproofing and anti-moisture agent in coatings, adhesives, printing inks, and heat-seal applications for food and pharmaceutical packaging .
3. Dicyclohexyl phthalate also functions as a processing aid to enhance resin flow during manufacturing and as a diluent in adhesives, peroxides, and cleaning agents for industrial equipment .

1. Store Dicyclohexyl phthalate in a tightly sealed container in a cool, dry, well-ventilated area, separated from strong oxidizing agents, acids, and bases to prevent decomposition and hazardous reactions .
2. Keep DCHP CAS 84-61-7 in an area without drain access and protect from open flames, as it is combustible with a flash point of 180-190°C .
3. Handle Dicyclohexyl phthalate using appropriate personal protective equipment including gloves and safety goggles, as it may cause skin and eye irritation upon contact .

1. Isolate the spill DCHP CAS 84-61-7 area and wear full protective equipment including a NIOSH-approved respirator; sweep up solid Dicyclohexyl phthalate using non-sparking tools into sealed, labeled containers, moistening first to prevent dusting .
2. For small spills, dampen Dicyclohexyl phthalate with alcohol, transfer to a suitable container, and solvent-wash contaminated surfaces with alcohol followed by soap and water .
3. Personnel cleaning Dicyclohexyl phthalate spills must prevent entry into drains or waterways, as Dicyclohexyl phthalate may bioaccumulate and is very toxic to aquatic life with long-lasting effects .

1. Dicyclohexyl phthalate is classified with GHS signal word "Danger" and may cause skin and serious eye irritation (H315, H319), respiratory irritation (H335), and may cause an allergic skin reaction (H317) .
2. DCHP CAS 84-61-7 may damage the unborn child (reproductive toxicity Category 1) and has an oral LD50 > 2,000 mg/kg in rats .
3. Dicyclohexyl phthalate has a melting point of 63-67°C, is insoluble in water, reacts with acids and bases, decomposes on burning producing irritating fumes, and is classified for transport as an environmentally hazardous substance (UN3082, Hazard Class 9, PG III) .
