A bottle brush is a specialized tool designed specifically for cleaning baby bottles; it must be used in conjunction with the bottles and cannot be substituted by an ordinary toothbrush. In English, this tool is referred to as a "bottle brush." Common types available on the market include rotating nylon brushes, rotating sponge brushes, and standard cleaning brushes. Based on the material of the brush head, they can be broadly categorized into four types: nylon, sponge, silicone, and a combination of sponge and nylon. Among these, nylon brushes-typically constructed from nylon bristles and a stainless steel frame-are suitable for glass bottles; sponge brushes are designed specifically for plastic bottles and must be kept dry to prevent mold growth; silicone bottle brushes also constitute a widely used category. When making a purchase, consumers should prioritize factors such as bristle density, brush head shape, and softness. It is advisable to prioritize brushes featuring nylon bristles and a 304 stainless steel frame, while also checking to ensure the bristles do not shed easily, thereby minimizing the risk of residue contamination. Furthermore, the choice of brush type should be tailored to the specific material of the baby bottle being used.
Bottle brushes are required to undergo rigorous testing regarding their physical properties, chemical safety, and microbiological indicators. Testing parameters typically include structural stability and heavy metal migration levels, with compliance mandated by national standards such as GB 4806.1-2016 and GB 31604.8-2021. After use, the bottle brush should be sterilized at high temperatures simultaneously with the baby bottle-for instance, by boiling in water for 3 to 5 minutes. Additionally, brushes should be replaced periodically to prevent bacterial proliferation; it is recommended that sponge bottle brushes be replaced every 1 to 2 months, while nylon bottle brushes should be replaced every 2 to 3 months. Industry surveys indicate that market demand for bottle brushes is influenced by various factors, including consumer preferences, demographic structures, and manufacturing technologies; projections suggest that by 2025, the market size for silicone bottle brushes-both globally and within China-will reach a scale of hundreds of millions.
