Phthalates

Phthalates

Phthalates (/ˈθæleɪts/, THAL-ayts), also known as phthalate esters, are a group of chemical compounds primarily used as plasticizers. They are derived from phthalic acid and are mainly used to increase the flexibility, transparency, durability, and longevity of plastics.

Etymology

The term "phthalates" comes from phthalic acid, which itself is derived from the word "naphthalene". Naphthalene is a white crystalline volatile solid derived from coal tar, and the name comes from the Latin naphtha, meaning "oil or bitumen".

Types of Phthalates

There are several types of phthalates, including:

• Diethyl phthalate (DEP)
• Dibutyl phthalate (DBP)
• Diisobutyl phthalate (DIBP)
• Benzyl butyl phthalate (BBP)
• Dinonyl phthalate (DNP)
• Diisodecyl phthalate (DIDP)
• Diisononyl phthalate (DINP)
• Di(2-ethylhexyl) phthalate (DEHP)

Uses

Phthalates are used in a wide variety of products, including:

• Vinyl flooring
• Adhesives
• Automobile parts
• Toys
• Food packaging
• Pharmaceuticals
• Personal care products

Health Effects

Exposure to phthalates has been linked to a variety of health issues, including:

• Endocrine disruption
• Reproductive toxicity
• Liver toxicity
• Kidney toxicity
• Lung toxicity

Regulation

Due to their potential health effects, the use of certain phthalates in children's toys and childcare articles has been restricted in the European Union and the United States.
