1. Airtight packaging blocks the air and prevents microbial pollution


For skin care products, rich water/oil/amino acids/minerals/proteins/monosaccharides are breeding grounds for bacteria. Skin care products are the safest in the production process, but when consumers open the package and start using them, skin care products face frequent opening actions, humid air, dust, sweat or other skin care products. The microbiological challenge of the product, so the anti-corrosion system of the product is an absolutely indispensable part.


So here comes the problem. If you want to have a perfect antiseptic system, preservatives are definitely indispensable. However, many students with sensitive skin will be uncomfortable with some preservatives. For example, the concentration of phenoxyethanol, which is well-known, needs to be strictly controlled when it is added to skin care products. Otherwise, skin will easily appear during use. Redness, fever, etc.


However, the emergence of the vacuum bottle has solved this problem well. The structure of the vacuum bottle is very tight and can isolate the air well, avoiding the risk of contamination by external microorganisms from the source. After the problem of external pollution is solved, the preservative of the product can naturally reduce its added concentration accordingly. 


For example, the recommended concentration of phenoxyethanol is 0.2%~1%. If it is an ordinary jar cream packaging, after a series of anti-corrosion challenge tests, the added safety concentration is finally set at 0.8%, but the vacuum bottle cream packaging has undergone anti-corrosion challenges After the test, 0.2% can be selected as a safe concentration. The birth of vacuum packaging materials allows the preservative system to be established in accordance with the critical concentration, avoiding the problem of sensitive skin with intolerance to preservatives, making the product gentler and safer, and avoiding pollution problems caused by improper use.

2. Airtight packaging blocks the air, and the active ingredients are more stable


The most commonly known ingredient in skin care products is VC. Ascorbic acid is stable in powder state, but after adding water, the VC state after dissolving ascorbic acid powder is extremely unstable and begins to undergo oxidation reaction. Then it becomes dehydroascorbic acid which has no skin care value. In fact, not only VC has such shortcomings, but many plant extracts, polyphenols, and flavonoids have the problems of instability and easy oxidative inactivation.


The excellent airtightness of the airless bottle can prevent the skin care products from coming into contact with oxygen in large amounts, help delay the oxidation and deactivation of active ingredients, and maintain the "freshness" of the skin care products.


Then some students will ask: "Why not use glass vacuum flask? In this way, the texture is also available." In fact, the production process and material properties of the glass bottle determine that it cannot achieve the conditions required for the vacuum flask. The bottle requires a certain degree of expansion and flexibility of the material. In addition, the glass material has the disadvantage of being easily damaged during use.


3. The discharge volume of the pump head is accurate and controllable


There will be no problem of too much or too little material when used in a normal state, so it is convenient to control the appropriate dosage and avoid the problem of waste or too much rubbing. However, ordinary wide-mouth, squeeze packaging is not easy to accurately control the dosage, and the process of use will become more troublesome.
