TRICRESYL PHOSPHATE

Description

Tricresyl phosphate (TCP) is a synthetic organophosphate compound used in various industrial applications, including as a plasticizer and flame retardant. While not commonly found in skincare formulations, its presence in certain products has raised concerns due to potential health risks.

TCP exists in three isomeric forms: ortho-, meta-, and para-tricresyl phosphate. The ortho-isomer is considered the most toxic. TCP is a colorless to pale yellow liquid with a mild odor, and it's known for its thermal stability and resistance to oxidation.

In rare instances where TCP might be encountered in personal care items, it's crucial to note its potential for neurotoxicity and reproductive toxicity, particularly with prolonged exposure. TCP can be absorbed through the skin, making topical exposure a concern.

Regulatory bodies, including the European Chemicals Agency (ECHA), have classified TCP as a substance of very high concern (SVHC) due to its reproductive toxicity. As a result, its use in consumer products is highly restricted and monitored.

Given its toxicological profile, alternative ingredients are strongly preferred in skincare and cosmetic formulations to ensure product safety and consumer well-being.
