Plasticizers
Diisobutyl Phthalate (DIBP)
DIBP, CAS No. 84-69-5 is an odorless plasticizer and has excellent heat and light stability. It is the lowest cost plasticizer for cellulose nitrate. DIBP has lower density and freezing point than DBP (dibutyl phthalate, CAS No.: 84-74-2). It has similar properties as dibutyl phthalate and can be used as a substitute for it. Its refractive index is 1.488 – 1.492 (at 20 °C, D).
Diisodecyl Phthalate (DIDP)
Diisodecyl phthalate (DIDP) CAS No. 26761-40-0 is a commonly used plasticizer, used in the production of plastic and plastic coating to increase flexibility. It is a mixture of compounds derived from the esterification of phthalic acid and isomeric decyl alcohols.
The coating on furnishings, cookware, pharmaceutical pills, food wrappers and many other products may contain DIDP or other phthalates.
Diisonoyl Phthalate (DINP)
Diisononyl phthalate (DINP) CAS No. 28553-12-0 is a phthalate used as a plasticizer. DINP is typically a mixture of chemical compounds consisting of various isononyl esters of phthalic acid.
Dioctyl Phthalate (DOP)
Dioctyl Phthalate (DOP) CAS No. 117-81-7 is a colorless, viscous liquid and soluble in oil, but not water. DOP has common applications in plastics, such as medical supplies, PVA and rubber manufacturing, wood coatings, and is sometimes used as a waxing agent.
Dioctyl Terephthalate (DOTP)
Dioctyl terephthalate (bis(2-ethylhexyl) benzene-1,4-dicarboxylate or Di(2-ethylhexyl) terephthalate), commonly abbreviated DOTP or DEHT, CAS No.6422-86-2 is an organic compound with the formula C6H4(CO2C8H17)2. It is a non-phthalate plasticizer, being the diester of terephthalic acid and the branched-chain 2-ethylhexanol. This colorless viscous liquid used for softening PVC plastics is known for chemical similarity to general purpose phthalatessuch as DEHP and DINP, but without any negative regulatory pressure. It possesses very good plasticizing properties and may be used as a direct replacement for DEHP and DINP in many applications.
Dipropylene Glycol (DPG)
Dipropylene glycol CAS No. 25265-71-8 finds many uses as a plasticizer, an intermediate in industrial chemical reactions, as a polymerization initiator or monomer, and as a solvent. Its low toxicity and solvent properties make it an ideal additive for perfumes and skin and hair care products. It is also a common ingredient in commercial fog fluid, used in entertainment industry fog machines.
Phthalic Anhydride
CAS No. 85-44-9 The primary use of phthalic anhydride is as a chemical intermediate in the production of plastics from vinyl chloride. Phthalate esters, which function as plasticizers, are derived from Phthalic Anhydride. Phthalate plasticizers are used for the production of flexible PVC products such as cables, pipes and hoses, leather cloth, shoes, film for packaging etc. Phthalic anhydride has another major use in the production of polyester resins and other minor uses in the production of alkyd resins used in paints and lacquers; certain dyes (anthraquinone, phthalein, rhodamine, phthalocyanine, fluorescin, and xanthene dyes); insect repellents; and polyester polyols for polyurethanes. It is also utilized as a rubber scorch inhibitor and retarder.
Propylene Carbonate
Propylene carbonate CAS No. 108-32-7 as a solvent it is frequently used as a high-permittivity component of electrolytes in lithium batteries, usually together with a low-viscosity solvent (e.g. dimethoxyethane). Its high polarity allows it to create an effective solvation shell around lithium ions, thereby creating a conductive electrolyte. However, it is not used in lithium-ion batteries due to its destructive effect on graphite. Propylene carbonate can also be found in some adhesives, paint strippers, and in cosmetics. It is also used as plasticizer.
