The invention provides a polypropylene composition and a polypropylene material. The polypropylene composition contains impact polypropylene and a polyethylene homopolymer. The impact polypropylene contains a polyethylene homopolymer and a polypropylene copolymer elastomer. The polypropylene composition comprises, by weight, 50-75% of the impact polypropylene and 25-50% of the polyethylene homopolymer. At a temperature of 190 DEG C, under load of 2.16kg, the polyethylene homopolymer has a melt index of 5-7g/10min. The polypropylene material prepared from the polypropylene composition has excellent stress whitening resistance and high elongation at break.
