71662-46-9 Usage
General Description
1,2-Benzenedicarboxylic acid, di-C8-10-alkyl esters, also known as phthalates, are a group of chemicals commonly used as plasticizers in the production of PVC and other plastics. They are added to plastics to increase their flexibility, transparency, and durability. However, phthalates are known to be harmful to human health, with potential adverse effects including endocrine disruption, reproductive toxicity, and developmental toxicity. They can leach out of products and into the environment, posing a risk to wildlife and potentially contaminating food and water sources. Due to these concerns, the use of phthalates in certain products has been restricted or banned in some countries.
