What are the requirements for the storage environment of cosmetic jars

As the main packaging form of cosmetics, the storage environment of cosmetic jars plays a vital role in maintaining the quality of cosmetics, extending the shelf life and ensuring consumer safety. In order to ensure that cosmetics do not undergo chemical or physical changes during storage, multiple factors such as temperature, humidity, light and air circulation need to be considered comprehensively to effectively maintain their original performance and safety.

Temperature control: maintaining a stable storage environment
The storage temperature of cosmetic jars is one of the important factors affecting product stability. Too high a temperature will accelerate the decomposition and oxidation of certain ingredients, resulting in a decline in product quality; while too low a temperature may freeze the water in the cosmetics and destroy its physical structure. Therefore, it is recommended to store cosmetic jars in a relatively constant environment, with an ideal storage temperature range of 15°C to 25°C. This temperature range helps maintain the stability of the ingredients in cosmetics and effectively prevents product deterioration.

Humidity regulation: avoid extreme environmental influences
Humidity is another key factor affecting the storage environment of cosmetic jars. Too high humidity may cause rust and corrosion on the surface of the jar and affect the sealing of the product; while too low humidity may cause the water in the cosmetics to evaporate, affecting its texture and effect. To ensure the best condition of cosmetics, it is recommended to control the relative humidity between 45% and 65%. By adjusting the humidity of the storage environment, product quality problems caused by humidity changes can be effectively prevented.

Light control: Reduce the impact of light on cosmetics
Light also has a significant impact on the stability of cosmetics. High-intensity light such as ultraviolet rays can accelerate the degradation and oxidation of certain ingredients in cosmetics, causing product discoloration and deterioration. Therefore, cosmetic jars should be stored in an environment that avoids direct sunlight. It is recommended to use blackout curtains or dedicated storage cabinets to reduce the negative impact of light on cosmetics. In addition, long-term exposure to light may also cause product quality to deteriorate, so cosmetic jars should be avoided from being placed in a strong light environment for a long time.

Air circulation: Maintain a suitable ventilation environment
Air circulation is also crucial to the storage environment of cosmetic jars. An overly closed environment will lead to excessive concentrations of oxygen and carbon dioxide in the air, thereby accelerating the oxidation reaction of cosmetic ingredients; while an overly open environment may cause cosmetics to be contaminated by dust and microorganisms. Therefore, cosmetic jars should be stored in an environment with moderate air circulation, avoiding both excessive closure and preventing the intrusion of external pollutants.
