The disclosure relates to a high-density polyethylene (HDPE) composition with resistance to deterioration in the presence of chlorinated and non-chlorinated water at temperatures in the range of about 0 °C to about 100 °C, due to a particular stabilizer system which is composed of a hindered phenol antioxidant, a phosphonite or phosphine antioxidant, and a natural or synthetic hydrotalcite. The stabilizer system is specifically tailored to protect the HDPE as well as other polyolefins against deterioration and degradation.
