Natural cosmetics – let’s get away from preconceived ideas

Angelika Meiss, Cossma, 17 Jan 2011 09:30

Following the successful history of natural cosmetics in the last ten years it is hardly expected that this megatrend will suddenly come to an end in 2011, but neither will green cosmetics grow as fast and as furiously as has happened in recent years – these are the conclusions of a recent survey by the IKW.

Natural ingredients will continue to be in demand
But for all of those suppliers who are enjoying the boom, and launching products onto the market with natural alternatives to what are now regarded as doubtful ingredients, the opportunities for this strategy are good not only to arouse significant consumer interest but also to be a profitable venture.

Manufacturers should however also be clear that nowadays it is not enough to launch new products that – like many others –  contain new ingredients and are simply certified by one of the many eco labels. In fact new ingredients for natural cosmetics must be shown to be equally as effective as traditional ingredients.

Safety evaluation of natural substances
And that should be the challenge that will keep the ingredients suppliers on their toes in the coming years – even if only in matters of product safety. For well-documented synthetic ingredients there are already detailed safety evaluations, but what about safety evaluation of natural ingredients?

At the moment the EU Cosmetics Directive is mainly concerned with the safety of chemically well-defined ingredients.

The way that this safety evaluation is approached cannot necessarily be applied to natural substances. This is an area that requires further study and investment to allow such shortcomings to be cleared up.

Which ingredients tend to be avoided?
It is interesting to take a closer look at substances that the consumer will not accept in natural cosmetics products.

According to the presentation “Best of both worlds: reaping the benefits of both natural and natural-inspired products”, given by Kline at the Natural Beauty Summit (Paris, November 2010) these include the following substances that have a very low level of acceptance in natural cosmetics: paraben as preservatives, propylene glycol as a moisturiser, phthalate as a solvent, petrolatum as an emollient, chemical UV filters, silicones and strong surfactants such as sodium lauryl sulphate.

Dr. Karl Lintner of Kal’Idées is however of the view that the way that these ingredients tend to be classified totally misses certain important aspects: “Parabens are also found in natural substances and extracts  - even at a very high cost – or in “natural” fermented products. So parabens must therefore meet the requirements of a natural product. Chemical sun filters, that are avoided in natural cosmetics, are a significant advance on mineral titanium dioxide or zinc oxide. If these minerals are treated as if they were more natural than Avobenzone or cinnamic acid ester, one is totally ignoring the manufacturing process which is necessary to produce (nano!) micronised metal oxides from these ores.

But if we want to protect the consumer from UV-induced skin damage we should be using substances with scientifically proven efficacy and not take chances with untested natural UV absorbers. Silicones are also not natural, but that does not mean that they present a safety risk. If they are not used then one is obliged to forgo their technical and textural benefits. And with regard to the “strong” surfactant sodium lauryl sulphate, Rhodia have just recently received Ecocert approval for their sodium lauryl sulphate, which is based on ethoxylation with the “ill-reputed” ethyl oxide, but whose origin is  a natural sugar molecule. But is such a surfactant less aggressive because it has an eco label?

Johann Wiechers of JW Solutions made it clear in his presentation: “Natural Ingredients – the new cosmetic religion”: “The body does not differentiate between plant-derived CH2OH-CHOH-CH2OH (glycerine) and animal-derived CH2OH-CHOH-CH2OH (glycerine) because both are the same.”

In other words: In the future it will be necessary to regard natural cosmetics “dogma” differently from before.

Natural cosmetics without sustainability?
Another topic that will play a more significant role in the future is the whole question of sustainability – a topic that from a marketing point of view has been much harder to exploit than the “natural” theme. But just how natural is a natural cosmetics product, with certified ingredients but that cannot be produced in a sustainable way? In any case it is quite clear that there is still a lot to do before the subject of natural cosmetics is totally clarified and defined. Let’s get started !
