Does the airless cream bottle need to be sterilized at high temperature?

Airless cream bottles do not need and are not suitable for high-temperature sterilization. Its core design relies on plastic materials and precision sealing structures. High temperatures will destroy the dimensional stability of internal components, leading to piston displacement, seal failure and other problems, which in turn cause leakage or failure to discharge when pressed. For example, the body of a airless cream bottle is usually made of thermoplastics such as PP and PE. Although it is resistant to chemical corrosion, high temperatures may cause deformation, and the breathable piston structure at the bottom is prone to lose elasticity at high temperatures, affecting the vacuum sealing effect. If cleaning or sterilization is required, it is recommended to use a gentle method: wash with warm water and neutral detergent, avoid using volatile solvents such as alcohol, and dry naturally in a ventilated place. For scenarios with higher sterility requirements (such as reuse or repackaging of medicines), you can refer to the low-temperature sterilization solutions recommended by some manufacturers, such as wiping with a low-concentration hydrogen peroxide solution, or using a non-corrosive professional disinfectant. In addition, high-temperature baking, compressed air jets, etc. should not be used, otherwise the bottle will be permanently damaged. Therefore, following the product manual or the maintenance guidelines provided by the manufacturer is the key to ensuring the functionality and hygienic safety of the airless cream bottle.
