The invention provides a novel fibroin-based infant toner product and a preparation method thereof. The infant toner product consists of A, B and C phases, and the preparation method comprises the following concrete steps of (1) heating, stirring, and mixing fibroin, water-soluble jojoba oil and butylene glycol cocoate to obtain A phase, adding aloe gel in deionized water, slowly stirring the aloe gel and the deionized water, adding xanthan gum, and evenly mixing the aloe gel, the deionized water, and the xanthan gum to obtain phase B; and (2) continuously stirring B phase, dropwise adding A phase, carrying out homogenizing for 2-4 minutes at the revolving speed of 5000rpm (revolutions per minute), then adding citric acid, tea polyphenol and deionized water, continuously stirring the mixture for 20-25 minutes, and naturally cooling the mixture to room temperature, thereby obtaining the fibroin-based infant toner product. The fibroin-based infant toner product is gelatinous, overcomes the defects of traditional talcum powder, and does not harm infant eyes or mouth; in addition, most raw materials adopted in the product are extracts from natural plants or animals, therefore the product does not have toxicity or stimulation to infant skin, and is safe and effective, with refreshing and moisturizing efficacy.
