Texas Attorney General Ken Paxton has launched an investigation into athletic apparel company Lululemon concerning the presence of per- and polyfluoroalkyl substances (PFAS), commonly known as 'forever chemicals,' in the company's products.

PFAS are synthetic chemicals that have been linked to various health concerns and are called 'forever chemicals' because they do not break down naturally in the environment or human body. These substances have been used in various consumer products for their water and stain-resistant properties.

The investigation represents the latest regulatory scrutiny facing companies over the use of PFAS in consumer goods. The chemicals have drawn increased attention from health authorities and environmental groups due to their persistence in the environment and potential health risks.

Lululemon's stock price declined following news of the Texas investigation. The athletic wear company has built a significant market presence in the premium fitness apparel sector, with products ranging from yoga pants to athletic tops and accessories.

The scope and timeline of the Texas Attorney General's investigation have not been detailed. Lululemon has not yet publicly responded to the announcement of the probe.
