Is the shaking ball inside the spray bottle a glass ball?

This material is often used in spray bottles that hold liquids with insoluble particles or components requiring chemical stability. For example, spray paints and some sunscreen sprays containing zinc oxide or titanium dioxide rely on glass shaking balls. Glass is chemically inert, so it will not react with the paint pigments, physical sunscreen ingredients, or even medical spray substances, thus avoiding contamination of the products. Meanwhile, high-strength glass balls can effectively stir the precipitated particles during shaking to prevent nozzle blockage. You can also find specialized glass mixing balls for sprayers in the market, with diameters ranging from 1mm to 16mm to meet different needs.

It is a common material for shaking balls in many aerosol cans and large-capacity spray bottles, such as industrial cleaning sprays and some cosmetic aerosols. Stainless steel shaking balls are heavier, and when the bottle is shaken, they generate a stronger impact force, which can quickly stir thick liquids or components that are prone to delamination. Additionally, stainless steel is rust – resistant and durable, making it suitable for scenarios where the spray bottle is used frequently and under certain pressure.

It is mostly used in low-cost, simple daily spray bottles, like small disposable hydrating spray bottles or ordinary household cleaning spray bottles. Plastic shaking balls have the advantages of low production costs and being shatterproof, which is very suitable for thin liquids that do not require strong stirring. However, due to the possible slight adsorption of some plastics, they are rarely used in spray bottles containing complex chemical ingredients or high – end cosmetic products.
