I have studied and formulated skin-care for almost 20 years; first for my own pleasure and then professionally. I have always wanted to keep my products as natural and pure as possible which is quite easily done, but the “shelf-life” of the product is very short and it has to be kept in the fridge. Natural skin care is like fresh food – you need to use it within a certain time, depending on what you have put in there; Herbs, for example, naturally makes the product more sensitive to mold….you get the picture.
To make a creme or a lotion an emulsifier is needed to mix the fatty substances (oil) and water. The only purely natural emulsifiers are eggs and cream (compare it to cooking) which go off quickly…wouldn’t want that in your cream… All emulsifiers used are chemically changed to be able to combine oil and water. The ones I use are the same that are used by the food-industry for making ice-cream and bread. I figure, if you can eat it, you can put it on your skin.
Almost everything is natural; poo is natural, as is mineral oil (derived from the petroleum industry). That doesn’t mean it’s good for us. So the labeling of purely natural is misleading on 2 points: Natural does not necessarily mean good. If it is emulsified (oil + water) it is not natural, even if the original product for the emulsifier comes from a natural source.
BIO or organic is also interesting to find on products. I picked up a hand-creme (oil+water) the other day which says: 95% of the plant ingredients come from organic farming (and how many % of the total product is plant material?) 17% of the total ingredients come from organic farming (so maybe that means that there is 17% of plant material in the product?) 100% of the total ingredients come from a natural origin (can be absolutely true – remember what I said about natural…?)
