Sodium Tripolyphosphate (also called STPP or E451) is added to dog foods as a preservative and to help moist foods to retain moisture so that they appear fresher for longer.
Although STPP is generally recognised as safe, it has been listed by the US National Institute for Occupational Safety and Health as a possible neurotoxin and is widely recognised as a mild skin irritant. We therefore recommend steering clear of foods containing STPP, especially if your dog is prone to skin problems.
