How cosmetic airless pump bottles realize the anti-oxidation function

Oxidation is a chemical reaction that occurs when substances come into contact with oxygen, leading to various undesirable effects, such as changes in color, and texture, and the breakdown of active compounds. Cosmetic airless pump bottles are specifically designed to minimize or eliminate oxidation, making them a crucial choice for products that contain ingredients susceptible to oxidation. 
Air-Tight Environment:
The core principle of oxidation prevention in airless pump bottles is the creation of an air-tight environment within the container. This is achieved through the vacuum-based system, where the inner pouch collapses as the product is dispensed, maintaining an air-tight seal. The absence of air within the container greatly reduces the opportunities for oxidation to occur.
Oxygen Exclusion: Cosmetic airless pump bottles minimize the contact between the product and oxygen. Oxygen is a common catalyst for oxidation, and by preventing its entry, the bottles effectively slow down or prevent the oxidation process.
Preservative Reduction: In many cases, the reduction of oxygen exposure allows cosmetic manufacturers to use fewer preservatives in their formulations. This aligns with the growing demand for preservative-free or low-preservative skincare products.
Protection of Active Ingredients:
Many cosmetic products contain active ingredients that provide specific benefits to the skin. These active compounds can be highly sensitive to oxidation, which can render them ineffective. Cosmetic airless pump bottles safeguard the potency of these ingredients.
Vitamins and Antioxidants: Common skincare ingredients like vitamin C, vitamin E, and various antioxidants are prone to oxidation. When exposed to air, these ingredients lose their effectiveness rapidly. In airless pump bottles, these ingredients remain protected, ensuring that the product delivers the promised benefits.
Hydration Ingredients: Moisturizers and hydrating serums often contain hyaluronic acid, which can degrade when exposed to oxygen. Airless pump bottles keep such ingredients potent, ensuring they provide long-lasting hydration to the skin.
Consistency and Shelf Life:
Oxidation can lead to changes in the consistency and shelf life of cosmetic products. These changes are often undesirable for consumers and can impact the overall user experience. Cosmetic airless pump bottles help maintain product consistency and extend shelf life.
Texture Preservation: The absence of oxidation means that the texture and appearance of the cosmetic product remain consistent from the first use to the last. Consumers can rely on a product's quality and performance throughout its usage.
Extended Shelf Life: Cosmetic airless pump bottles can extend the shelf life of products compared to traditional packaging methods. This is especially valuable for products with natural or organic ingredients that are more prone to degradation.
