NOVELTY - Bacteriostatic and stain-removing washing powder comprises 3-7 pts. wt. biomass graphene, 1-3 pts. wt. dirt dispersant, 0.2-0.5 pts. wt. antifoaming agent, 13-20 pts. wt. alkyl aryl sodium sulfonate, 13-17 pts. wt. sodium silicate, 23-33 pts. wt. sodium alkyl benzene sulfonate, 0.8-1.3 pts. wt. sodium xylene sulfonate, 1-3 pts. wt. softening agent, 0.3-0.8 pts. wt. anti-dyeing agent, 17-26 pts. wt. anhydrous sodium sulfate, 0.03-0.08 pts. wt. spice, 13-18 pts. wt. sodium dodecyl sulfonate, 5-9 pts. wt. sodium carboxymethyl cellulose and 11-20 pts. wt. de-ionized water. USE - Used as bacteriostatic and stain-removing washing powder. ADVANTAGE - The bacteriostatic and stain-removing washing powder has strong decontamination ability and antibacterial effect; and provides gentle and soft feeling to hand skin. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for preparing bacteriostatic and stain-removing washing powder, comprising (i) adding deionized water into the reaction kettle, adding dirt dispersant, antifoaming agent, alkyl aryl sodium sulfonate, sodium silicate, sodium alkyl benzene sulfonate, sodium xylene sulfonate, softening agent, anti-dyeing agent, anhydrous sodium sulfate, sodium dodecyl sulfonate and sodium carboxymethyl cellulose into the deionized water by stirring at 800-1000 revolutions/minutes for 20-30 minutes and mixing well and evenly; (ii) adding biomass graphene and stirring at 2500-3000 revolutions/minute for 30-40 minutes to disperse the biomass graphene fully to obtain the mixture; and (iii) adding the spices into the mixture, spray drying it, setting the inlet air temperature to 150-160 degrees C, and the outlet air temperature to 70-80 degrees C, the hot air speed is 4-5 m3/min, the feeding speed is 30-40 ml/min, and the rotating speed of the atomizer is 200-300 revolutions/minute.
