How is the sealing performance of this Mini clear round lip gloss container? Can it effectively prevent the lip gloss from volatilizing or deteriorating?

This Mini clear round lip gloss container adopts a high-precision thread design. The thread profile has been carefully calculated and polished, and the thread depth, pitch, and fillet transition between the top and bottom of the thread have achieved a better matching degree. When the user rotates and tightens the container cap, the thread can bite tightly to form a multi-layer sealing defense line, effectively preventing the outside air from entering the container, and reducing the risk of lip gloss volatilizing due to contact with air.

At the junction of the container cap and the bottle body, a high-quality sealing gasket is equipped. The gasket is usually made of silicone or rubber material with good elasticity and sealing. Its shape fits perfectly with the bottle mouth. When the container cap is tightened, the gasket will be subjected to a certain compression force, resulting in uniform elastic deformation, thereby tightly filling the tiny gap between the cap and the bottle, further enhancing the sealing effect, and preventing the lip gloss ingredients from deteriorating due to changes in the external environment.

The bottle mouth adopts a unique trumpet shape. This design is not only more convenient when applying lip gloss, but also can reduce lip gloss residue to a certain extent. At the same time, the bell mouth and the sealing structure inside the container cover cooperate with each other to form a relatively closed space, which further prevents the volatilization of lip gloss and the intrusion of external impurities.

After rigorous laboratory testing, under the conditions of simulating daily use environment, after placing this mini container full of lip gloss for a period of time, it was measured by professional testing equipment and found that the volatilization of lip gloss was extremely low. From the perspective of chemical stability, good sealing performance can prevent external factors such as oxygen, moisture, and dust from reacting with the ingredients in lip gloss. For some lip glosses containing active ingredients (such as vitamin E, plant essences, etc.), sealed containers can effectively delay the oxidation and decomposition of these ingredients, thereby extending the shelf life of lip gloss and maintaining its moisturizing and hydrating effects. Under normal use and storage conditions, the lip gloss in this container can maintain good quality and stability during the shelf life.
