Biophotonic jars and bottles . . .

. . . we’ll be launching a number of Kallisti skincare products.  A key consideration is choosing packaging.

Various materials offer different properties in terms of cost, availability (especially in the smaller quantities we are currently working to) weight and feel, and how well they maintain the integrity of the product.

There are also “eco” and recycling issues.  We are trying to avoid boxes, which tend to go straight in the bin after purchase.  It's not easy, as boxes add space for detailed product information which legislation says we have to share.

Like many things in life, choosing is often a bit of a compromise.

The Kallisti Skin Salvation stick is packed in a Polypropyene or “PP” tube.  PP is a very common plastic in wide use.  It is light and strong.  Skin Salvation ends up in toolboxes, pockets, luggage, sheds, gloveboxes.  It’s often outside.  It gets dropped.  PP was the best fit.  It’s also very recyclable and on the bottom of the tube you’ll see the universal recycling mark containing a number 5.

We’re launching a facial oil soon, followed next year by body and face moisturising creams.  Whilst researching containers for these, we discovered some very interesting glass.  You’ll have seen brown glass, green glass, and blue glass before.  This is violet glass.  It looks black, or with a strong light behind, blue.  “But it’s called violet glass” we hear you say . . . . read on.  

The reason glass is coloured, apart from aesthetic reasons, is to help block out harmful rays from sunlight which degrade the contents of a container over time.  Sunlight contains visible and invisible (such as UV-A and infra red) rays.  Some parts of the visible and invisible light spectrum have actually been found to have preservative effects.

 

 

Coloured glass of different types blocks light in different ways.  Violet glass blocks the complete spectrum of visible light with the exception of the violet part.  At the same time it will transmit UV-A, and infra-red light.  This combination offers optimal protection against degradation of the contents, thereby lengthening durability and potency.  It also means that potentially use of preservatives can be reduced.

The violet glass bottle and jar samples we’ve received are beautifully made.  We’re pretty excited about them!

Overall, glass containers are heavy, but feel nice in the hand, and of course are recyclable. We’re also hoping that people will upcycle them, due to the properties we’ve described.

 

Kallisti.
