A novel organic thiol stabilizer for PVC is described herein. Specifically, this novel thiol stabilizer for PVC is dipentaerythritol hexakis(mercaptoacetate). The organic thiol stabilizer of the present invention, when blended with halogen-containing polymers such as PVC, or derivatives thereof, provides advantages in cost and/or performance relative to existing organic stabilizers for PVC.
