Fabric-softening, garment-care and stain-removing detergent composition, preparation method thereof and detergent tablet

A detergent composition, wherein a raw material for preparing the detergent composition comprises the following components by mass percentages:

• anionic surfactant:
• 5-30%;
• nonionic surfactant:
• 5-20%;
• amphoteric surfactant:
• 1-10%;
• plant polysaccharide:
• 10-35%;
• builder:
• 5-20%;
• shape promoting agent:
• 2-10%;
• softening and antistatic agent:
• 0.5-5%;
• enzymatic preparation:
• 0-5%;
• chelating agent:
• 0.1-5%;
• essence:
• 0-5%;
• and a balance of water;
• a ratio of a total mass of the anionic surfactant, the nonionic surfactant, and the amphoteric surfactant to a mass of the plant polysaccharide is (0.9-5):1, a mass ratio of the anionic surfactant to the softening and antistatic agent is (3-17):1, the softening and antistatic agent comprises a strongly cationic softening and antistatic agent and a nonionic to weakly cationic softening and antistatic agent;
• the strongly cationic softening and antistatic agent comprises one or more of cationic wheat protein derivatives, quaternized wheat protein, methyl sulfate [ethoxylated cocoalkyl bis(hydroxyethyl) ammonium formate], or dodecyl hydroxyethyl quaternary ammonium salt;
• and
• the nonionic to weakly cationic softening and antistatic agent comprises one or more of hydrolyzed wheat protein/silicone copolymer, or hydrolyzed wheat protein/polyvinyl pyrrolidone (PVP) copolymer.
