The no preservative preservative Biovert

[Guest guest]

I've stumbled across a system called Biovert which claims to be the

product integrity answer for those who wish to have a preservative free

formulation.

The INCI name is Glucose & Glucose Oxidase & Lactoperoxidase

If you haven't already read about it here is the link to the company who

has released it.

I have a few questions that I would like to present to the unbiased panel

of experts :-)

It contains potassium thiocyanate. The manufacturer claims this is not

a major component of the system therefore is not required to be

included in the INCI nomenclature (is this true?). A quick google of

potassium thiocyanate produces an MSDS that reads like a horror story

and it's general use as a pesticide and fungicide (is this true?). Is it a

concern to have this chemical in skincare? Does it accumulate in the

body's tissues or organs?

If potassium thiocyanate is indeed used as a pesticide what would be

the point in claiming to have a preservative free product when it is not

pesticide free?

Are there increased risks to the manufacturer who has prolonged

exposure as opposed to the end user who has (in comparison) minimal

exposure.

It's effectiveness drops when temperatures reach over 35C. I am

thinking of hot Australian summers and postal conditions.... for

effectivity to drop does it need to only be exposed to that temperature

once or does it need to be maintained constantly at that temperature to

comprise the system?

They claim that high levels of cationic surfactants can compromise the

system, forgive my ignorance of chemical basics, but are cationic

emulsifiers like BTMS grouped in this category?

The above are all questions that are not addressed by the company's

FAQ on the Biovert system, so any clarification on the above points

would be gratefully received.

many thanks,
