According to a review in the journal Contact Dermatitis, here is what some really smart scientists, led by Michael Dyrgaard Lundov from Gentofte University Hospital in Denmark, have discovered:
- Any water-containing cosmetic product is at risk of contamination during the consumer use.
- To prevent contamination, some manufacturers may be adding higher concentrations of preservatives than are really needed.
- A number of studies point to a large range of preservative concentrations in cosmetics products.
- It is estimated that 6 percent of the population has a cosmetics related contact allergy, and the two main culprits are fragrances and preservatives. Out of the more common preservatives (parabens, formaldehyde) it is formaldehyde that seems to illicit the most reactions ranging from 2 per cent in Europe to 9 per cent in the US. The problem is that only half of the affected individuals can successfully read and understand ingredients lists, due to long chemical names and small print.
Ok - so we all kind of knew this. Water, if not properly preserved, is a good breeding ground for bacteria. So you can try and preserve any water-containing product naturally, using alcohol or certain essential oils or herbal extracts. Or, do what most big-name companies do: add parabens or formaldehyde. Add enough so any product will keep fresh in any conditions for 2-3 years. And then add just a bit more, to be on the safe side.
However, skin absorbs a lot of the things we put on it. Someone said that it's more important what we put on our skin than what we eat, as our stomach and our liver and kidneys will help filter out most of the toxins found in our food. If what we put on our skin gets absorbed by it, it enters the bloodstream directly and reaches every cell of our body.
That's why MuLondon products are always free from any man-made preservatives like parabens or formaldehyde, and the likes of 2-Bromo-2-nitropropane-1,3-diol, (DMDM) hydantoin, imidazolidinyl urea or diazolidinyl urea. This is achieved by making our moisturising creams water-free, which allows them to be extremely stable and resistant to contamination. Further to that, our base ingrediens are organic Shea butter and coconut butter, which do not oxidise easily. We then add some organic Rosemary extract and pure essential oils to further safeguard our products from deterioration. All this makes MuLondon products very concentrated - as you are not paying for any water in your jar, and the best natural skin food you can get.
