The invention relates to the field of enzyme bath products, in particular to a pomelo peel enzyme shower gel and a preparation method thereof and solves the technical problem that existing shower gelshave a single function and cannot improve skin issues. The pomelo peel enzyme shower gel is made mainly from pomelo peel fermented liquid, EDTA disodium salt (ethylenediaminetetraacetic acid disodiumsalt), glycerol, sodium C10-15 pareth sulfate, sodium lauryl sulfate, cocamide, potassium laureth phosphate, citric acid, sodium citrate, cocamidopropyl betaine, potassium cocoyl glycinate, cocamideDEA, polyquaternium-47, maltotetraose, a preservative and the like. The preparation method comprises adding sodium C10-15 pareth sulfate and sodium lauryl sulfate into water, allowing to dissolve, andmixing well; adding EDTA disodium salt, cocamide DEA and glycerol, heating and stirring to allow the temperature to reach 85 DEG C, preserving moisture, and sterilizing; cooling, stirring, adding therest materials, and stirring for homogenizing. The pomelo peel enzyme shower gel prepared herein can diminish inflammations and inhibit bacteria, relieve itching, remove acnes, and prevent and improve various skin issues.
