Plasticizers: Types, Uses, Classification, Selection & Regulation
Di-2-ethylhexyl-phthalate (DEHP, formula: C 6 H 4 (C 8 H 17 COO) 2) is a low molecular weight ortho-phthalate produced by esterification of phthalic anhydride with 2-ethyl-hexanol. It is non-volatile, colorless and odorless viscous liquid, soluble in oil, but not in water.

Dimethyl phthalate | ≥99%(HPLC) | plasticizer | AdooQ
Dimethyl phthalate, a known endocrine disruptor and one of the phthalate esters (PAEs), is a ubiquitous pollutant. Dimethyl phthalate is commonly used as a plasticizer to impart flexibility to rigid polyvinylchloride (PVC) resins.
Plasticizers: Synthesis of phthalate esters via FeCl3
Further optimization of the reaction allowed us to isolate diisopentyl phthalate (4c) in 82% by using 5 mol equiv of the alcohol 2c (i.e. 100 mmol) at 100 °C reaction temperature (entry 4). Similarly, dibutyl phthalate (4d), which is extensively used as a plasticizer, also can be produced by using n-butanol (2d) (entries 5 and 6
OVERVIEW OF DIALKYL - U.S. Consumer Product Safety Commission
diisobutyl phthalate, di-n-pentyl phthalate, dicyclohexyl phthalate, and di(2-propylheptyl) phthalate may also contribute to the cumulative health risks of phthalates. The purpose of this report is to provide a brief overview of the toxicity of the o-DAP’s.
- What are phthalate plasticizers?
- Some common phthalate plasticizers are: Bis (n-butyl)phthalate (DnBP, DBP), used for cellulose plastics, food wraps, adhesives, perfumes and also in cosmetics - about a third of nail polishes, glosses, enamels and hardeners contain it, together with some shampoos, sunscreens, skin emollients, and insect repellents
- Is dibutyl phthalate used as a plasticizer?
- Plasticizers are chemical additives that improve the plasticity of a polymer and are widely used, including in food packaging materials. One common phthalate plasticizer is dibutyl phthalate (DBP). A method to detect the presence of DBP in food samples is urgently needed.
- What is dimethyl phthalate used for?
- Dimethyl phthalate is used as an insect repellant. It has also been employed as a solvent for cellulose acetate. Dimethyl Phalate is the methyl ester of phthalic acid. Dimethyl phthalate is an ectoparasiticide and has many other uses, including in solid rocket propellants, plastics, and insect repellents.
- What are the side effects of dimethyl phthalate?
- The above information is edited by the chemicalbook of Tian Ye. Dimethyl phthalate displays no toxicity or side effects on the skin and mucous membranes, non-allergic and non-skin-permeable etc., it is very safe to use, it is noted that people with sensitive skin may cause skin allergies reaction if repellent ester component is excessive absorbed .
