• forming a parison by sequentially cooking and freezing the preform;
• and
• sequentially unfreezing, dehydrating and drying the parison to obtain the scrub sponge;
• wherein the konjac powder is in an amount of 3% to 15% w/w, and water is in an amount of 85% to 97% w/w;
• the alkalizer is in an amount of 0.3% to 3% w/w of the konjac powder, and the porogen is in an amount of 0.5% to 4% w/w of the konjac powder, and the scrub granule is in an amount of 20% to 45% w/w of the konjac powder;
