We chose to use this amazing type of violet glass because of its wonderful protective and UV blocking properties. Sunlight is known to accelerate the process of molecular decay and because Organic Skin is a product with the highest grade oils and essential oils, their sensitivity to light needs protecting to ensure their freshness and the best possible product. We also believe that using a pump cap is more hygienic and sterile. Pipette caps can sometimes touch skin or surfaces and when placed back into the product could introduce contamination.

Storage test with tomatoes

In order to more easily prove the quality protection given to food stored in MIRON violet glass, a microbiological experiment was carried out with cherry tomatoes.


During this test, a cherry tomato was stored for 7 months in a white glass and in a MIRON violet glass, and then kept at room temperature where sunlight could reach it. The result was photographed after 7 months. The microbiological changes of the tomato stored in white glass can be clearly seen. The tomato stored in MIRON violet glass however shows no loss of colour and no signs of drying out.

Storage test with chives

Sprayed, white, green and brown glass are permeable in the visible light spectrum and don’t offer enough protection against decomposition caused by light. As an experiment, several herbs and spices were stored for 3 months in several types of glass (white, brown, violet), and were either exposed to the sun for several hours a day or kept inside.


After 2 months, the visible quality change was recorded with photographs, and the difference in smell determined in a blind test with volunteers. The illustration shows clearly that the chive samples that were exposed to the sun have bleached in brown and white glass. As photographed in this illustration, the sample stored in MIRON violet glass shows no colour change. The smell of the chives stored in MIRON violet glass was also clearly stronger and fresher.
