Billionaire Anastasia Soare is used to raising eyebrows in the world of beauty. Now she’s getting ready to test demand for her rapidly growing cosmetics company in the trillion dollar leveraged-loan market. Anastasia Beverly Hills is seeking a $650 million loan to help fund a partial buyout by TPG Capital, according to a person with knowledge of the plan. The private equity firm agreed to buy a minority stake in Soare’s company last month in a deal that valued it at about $2.5 billion.
