PARIS - Liliane Bettencourt, the L'Oreal cosmetics heiress and the world's richest woman, has died at her home in a chic Parisian suburb. She was 94.

Bettencourt's daughter, Francoise Bettencourt Meyers, said in a written statement on Thursday that her mother "left peacefully" overnight in Neuilly-sur-Seine.

Liliane Bettencourt was the only child of Eugene Schueller, who founded L'Oreal in the early 20th century. Forbes magazine estimated her fortune to be worth $39.5 billion this year.

L'Oreal chairman and CEO Jean-Paul Agon expressed "great admiration" for Bettencourt. Agon said she "always looked" after the company and its employees and "she has personally contributed greatly to its success for many years".

Born in 1922 in Paris, she married French politician Andre Bettencourt at the age of 27. Her husband notably served as a minister at the end of the 1960s and beginning of the 1970s. He died in 2007.

Liliane Bettencourt inherited the L'Oreal fortune upon the death of her father in 1957. When the company went public six years later, she continued to own a majority stake.

As the world's leading beauty company, L'Oreal generated sales amounting to 26 billion euros ($31 billion) in 2016 and employs 89,300 people worldwide, according to the company.

Bettencourt's name has been involved in a politico-financial scandal known in France as the "Bettencourt Affair", which has wound its way through French courts and newspapers for years.

The case stemmed from a 2007 complaint filed by Bettencourt's daughter accusing one of her mother's closest friends, the photographer Francois-Marie Banier, of manipulating the elderly widow into giving him artwork and cash.

In 2015, a French court handed Banier a three-year prison sentence on charges of swindling millions of euros from Bettencourt by taking advantage of her weak mental state. The court acquitted a former ally of former president Nicolas Sarkozy in the case.

Sarkozy himself was cleared in 2013 of preliminary charges.

Bettencourt is survived by her daughter, Francoise, who was born in 1953.
