Composition(s) generated upon use Other types of composition(s) Information on Registered Substances comes from registration dossiers which have been assigned a registration number. WebPhthalates are added to TPE to make it more flexible, but they can also be harmful to human health. Studies have linked phthalates to hormone disruption, reproductive problems, and even cancer. However, it is important to note that the levels of phthalates in TPE products are generally low and pose minimal risk to human health.

WebNov 17, 2014 · Phthalates. Edwin Chiang May 18, 2005 Bio 2B. What are Phthalates?. Phthalates are a class of widely used industrial compounds used as plasticizers … Phthalates , or phthalate esters, are esters of phthalic acid. They are mainly used as plasticizers, i.e., substances added to plastics to increase their flexibility, transparency, durability, and longevity. They are used primarily to soften polyvinyl chloride (PVC). Note that while phthalates are usually plasticizers, … See more Due to the ubiquity of plasticized plastics, the majority of people are exposed to some level of phthalates. For example, most Americans tested by the Centers for Disease Control and Prevention have metabolites of … See more PVC Plasticisers Between 90 and 95% of all phthalates are used as plasticisers for the production of flexible PVC. They were the first commercially important compounds for this role, a historic advantage that has led to them becoming … See more Phthalate esters are the dialkyl or alkyl aryl esters of phthalic acid (also called 1,2-benzenedicarboxylic acid, not be confused with the structurally isomeric terephthalic or isophthalic acids); … See more A study in the peer-reviewed journal Environmental Pollution published October 12, 2024 found that high phthalate levels are weakly correlated with a greater risk of dying from any … See more Phthalates are produced industrially by the acid catalysed reaction of phthalic anhydride with excess alcohol. The synthesis of diethyl phthalate is illustrative of this: The properties of the phthalate can be varied by changing … See more The development of cellulose nitrate plastic in 1846 led to the patent of castor oil in 1856 for use as the first plasticizer. In 1870, camphor became the more favored plasticizer for … See more Phthalates are easily released into the environment. In general, they do not persist due to rapid biodegradation, photodegradation, and anaerobic degradation.
