Polyolefin compositions exhibiting enhanced stain resistance

A method for producing a household article displaying improved stain resistance characteristics, said method comprising:

• providing a nucleated propylene/ethylene impact copolymer having an ethylene content of up to 15 percent by weight, and a xylene solubles fraction having an intrinsic viscosity of at least 3 dL/g;
• wherein said xylene soluble fraction has an Mw/1000 of at least about 350;
• adding an additive package to said propylene/ethylene copolymer, said additive package consisting essentially of a phenolic antioxidant, a phosphite, and an acid scavenger, said phenolic antioxidant, phosphite, and acid scavenger being essentially free of sodium;
• wherein said propylene/ethylene impact copolymer is nucleated with a nucleating agent that is essentially free of sodium;
• forming said propylene/ethylene impact copolymer into a household article.

A household article exhibiting enhanced stain resistance, said household article comprising:

• a propylene homopolymer having a crystallinity of at least about 55 percent,
• said propylene polymer containing an additive package consisting essentially of:
• a phenolic antioxidant, a phosphite, and an acid scavenger;
• said household article being essentially free of sodium containing additives.
