Munich-based packaging specialist Corpack has unveiled an airless dispensing pen. The hybrid format combines the familiar, precise serum application with the technological vacuum protection of medical dosing systems, the company emphasises. As brands increasingly rely on highly sensitive active ingredients such as pure vitamin C, retinol or peptides, classic open systems such as traditional glass pipettes are sometimes reaching their limits. The airless pens are based on a vacuum-controlled piston mechanism, whereas conventional pipettes work with atmospheric pressure and riser tubes. The airless dispensing pens are available in 7.5 and 10 millilitre sizes.

No contact with outside air

The "skinification" trend in make-up and the growing demand for highly effective "clinical skin care" have fundamentally changed expectations for packaging, emphasises Corpack. Traditional packaging solutions often become an obstacle to the stability and effectiveness of the product. When the airless dispensing pen is activated, a partial vacuum is created in the pump chamber, which dispenses an exact microdose through the applicator tip. At the same time, an internal piston slides upwards to replace the volume. This keeps the ingredient in a hermetically sealed environment. The product never comes into contact with outside air. According to the company, this can increase the efficiency of antioxidants by up to 80 per cent.

Targeted applications without loss

Corpack reports that the airless pens have been specially developed for local application. Precise dosing is possible in any position. This makes the pen ideal for targeted applications around the eyes or on the scalp, for example for liquid concealers, highly concentrated spot treatments and exclusive lip oils. In addition, the airless dispensing pen offers an emptying rate of up to 99 per cent. This means that the contents are used almost completely, increasing sustainability.
