What are the benefits and drawbacks of glass as a packaging material?
Glass has a neutral effect upon the contents, it does not release or absorb anything and the qualities of a preparation remain unchanged.
- Glass bottles are particularly suitable for storing liquid formulations. We ensure that the liquid is extracted from the bottle hygienically and in a user-friendly manner with pumps, atomizers or pipettes.
- Glass has very high recycling quotas as it is a so-called permanent material, meaning that it can be infinitely recycled without losing its qualities.
Clear glass lets the light through and so is not suitable for light-sensitive preparations. The possible applications of glass packaging are extremely limited due to the other characteristics of the material (easily breakable, heavy and rigid), so for example, the use of glass in the shower is ruled outr for safety reasons.
- Thicker creams cannot be dispensed from bottles. Because our natural products do not contain any synthetic preservatives, for formulations containing water, such as our Day Creams, we cannot use jars, even if made of glass. The large surface area and the application method, e.g. using a finger, with a jar is a risk for microbial contamination with water-containing products. For stability reasons we cannot allow this (more on the importance of product protection in section 2).
- Manufacturing glass is very energy intensive and, due to its heavy weight, requires more energy for transport than, for example, lighter plastic packaging.
