4 Classification of Toy Materials

Toy materials are mainly divided into the following three categories:

— Category 1 toy materials: dry, brittle, powdery or flexible materials, including those that release powdery materials during play Solid toy material:

— Class II toy materials: liquid or viscous materials, including liquids or materials that may be ingested or come into contact with the skin during play Sticky toy material:

— Category III toy materials: scrapable materials, including materials that can be taken into the body by biting, tearing with teeth, sucking or licking, etc:

Solid toy material with or without coating: In addition, such materials also include toy materials not covered by Category 1 and Category 2 toy materials: other materials:

Table 1 gives common toy materials and their classification: Other toy materials need to be classified according to the above method:
