Patent number: 8962815Abstract: This invention relates to bis-azo colorants for use as bluing agents, laundry care compositions comprising bis-azo colorants that may serve as bluing agents, processes for making such bluing agents and laundry care compositions and methods of using the same. The bluing agents are generally comprised of at least two components: at least one chromophore component and at least one polymeric component. These bluing agents are advantageous in providing a whitening effect to fabrics, while not building up over time and causing undesirable blue discoloration to the treated fabrics.Type: GrantFiled: January 24, 2013Date of Patent: February 24, 2015Assignee: Milliken & CompanyInventors: Robert L Mahaffey, Jr., Xiaoyong Michael Hong, Eduardo Torres, Dominick J Valenti, Gregory Scot Miracle
