Children's toys are becoming increasingly diverse, and their gameplay is also labeled as "educational", which is deeply loved by children and parents. However, at the same time, there have been frequent news reports of children's toys causing harm, and the issue of toy safety has attracted much attention. Toys such as soft clay and crystal clay, which are soft and cute, have a series of safety issues caused by excessive addition of chemical components such as borax and preservatives in their products. Wuhan Time Technology, in conjunction with the toy market, customizes preservatives that are more suitable for children's toys. These preservatives are environmentally friendly, gentle, and skin friendly, and are more conducive to children's physical and mental health.
