In the beauty industry, the quality and effectiveness of cosmetics are often affected by oxidation. To solve this problem, cosmetic pumps play an important role as a key packaging technology.

Effect of oxidation on cosmetics
Many cosmetic ingredients, especially those containing active oxides, such as vitamin C, vitamin E, etc., are easily affected by oxygen and undergo oxidation reactions. Oxidation will not only cause changes in the color, taste and texture of the product, but may also reduce the efficacy and stability of the product, and even produce harmful substances, affecting the user's skin health.
How cosmetic pumps reduce the risk of oxidation

How do cosmetic pumps reduce the risk of oxidation? Its principles mainly include the following aspects:
Closed design: Cosmetic pumps usually adopt a closed design, which means that the product container is isolated from the outside environment. This design effectively reduces the chance of oxygen coming into contact with the product and reduces the possibility of oxidation. In contrast, traditional open bottles or squeeze packaging are susceptible to contamination from outside air, increasing the risk of product oxidation.
Antioxidant materials: Some components of cosmetic pumps are made of antioxidant materials, such as stainless steel, special plastics, etc. These materials have good oxidation stability and can effectively reduce the impact of oxygen on the pump body and internal components, thereby protecting the product from oxidation damage.
Precise dosage control: The cosmetic pump can accurately control the amount of product used each time, preventing users from frequently opening the packaging lid or touching the product. In this way, the product is exposed to air for less time during use and the possibility of oxidation is reduced accordingly.
Reduce air ingress: Cosmetic pumps are often designed to effectively reduce air ingress into product containers. There is usually a sealing structure or valve between the pump head and the bottle mouth to prevent air from entering the inside of the pump body. This design effectively reduces the risk of oxidation and protects the stability of product ingredients.

Features of different types of pumps to reduce oxidation risk
Different types of cosmetic pumps have their own characteristics in reducing the risk of oxidation:
Lotion pump: suitable for thicker liquid products such as essence and lotion. Lotion pumps are usually designed with a strong sealing structure, which can effectively isolate oxygen and reduce the risk of oxidation.
Spray pump: mainly used for spray-type products, such as lotion and makeup setting spray. The spray pump sprays the product evenly on the skin surface through fine mist technology, reducing the time the product is in contact with the air and reducing the possibility of oxidation.
Foam Pump: Especially suitable for foaming products such as cleansing foam and shampoo. The foam pump can convert liquid products into fine and soft foam, reducing the surface area of the product in contact with air, thereby reducing the risk of oxidation.
