What are phthalates classified?

Table of Contents

Phthalates may be classified into two groups based on molecular weight. Accordingly, low-molecular-weight phthalates (ester side-chain lengths, one to four carbons) include DMP, DEP, DBP, and DIBP, and high-molecular-weight phthalates (ester side-chain lengths, five or more carbons) include DEHP, DOP, and DINP.

How does phthalates affect the human body?

Phthalates, a family of industrial chemicals used to soften polyvinyl chloride (PVC) plastic and as solvents in cosmetics and other consumer products, can damage the liver, kidneys, lungs, and reproductive system.

What is the nickname for phthalates?

DNOP (di-n-octyl phthalate) DiNP (diisononyl phthalate) DEP (diethyl phthalate)

What is the purpose of phthalates?

Phthalates are a group of chemicals used to make plastics more durable. They are often called plasticizers. Some phthalates are used to help dissolve other materials. Phthalates are in hundreds of products, such as vinyl flooring, lubricating oils, and personal-care products (soaps, shampoos, hair sprays).

What are phthalates made from?

Phthalates are the esters of 1,2-dibenzene dicarboxylic acid; their general structure is given in Figure 1. They are produced by the addition of an excess of branched or normal alcohols to phthalic anhydride in the presence of a catalyst.

Are phthalates organic?

Phthalates are semi volatile organic compounds found in plastics because they make them soft and flexible. Though commercially useful, these chemicals can easily leach out of plastics to contaminate our food, water supply, and even the air we breathe. This is when phthalates become a real problem.

Are phthalates in diapers?

Several studies have detected phthalates in diapers. According to the Centers for Disease Control and Prevention’s Fourth National Report on Human Exposure to Environmental Chemicals, phthalates are commonly detected in the bodies of Americans, including in children.

Do plants absorb phthalate?

Interestingly, plants receive both nutrients and toxic substances through the roots as well as above-ground green parts. High accumulation of phthalates in stems of some types of crops has been reported [6].

Do phthalates leave the body?

Once they enter the body, phthalates undergo a series of phase I hydrolysis and phase II conjugation reactions and are subsequently excreted in feces and urine [15].
