Free of ingredients that are potentially harmful, the organic products can still cause allergies or irritations. Laurence Rabaud, head of R&D of cosmetic treatments Léa Nature, recommends opting for treatments that are hypo-allergenic. Meeting with this expert in organic cosmetics.
What is the specificity of formulation of a care hypoallergenic ?
The formulation of a care hypoallergenic happening, first of all, by a careful selection of raw materials and ingredients that will enter into its composition. In this case, a lot of materials are excluded due to their allergenic potential, as everything that comes from nuts such as hazelnut or essential oils in general, fruits and nuts, such as walnut or hazelnut.
We will be very careful also to ensure that the ingredients are well tolerated by the skin ; we will avoid anything that has ingredients that are potentially drying or irritating like alcohol o the surface-active sulfated (sulfate).
Another crucial point in the formulation of a care hypoallergenic is the choice of the fragrance and the preservative system that should not contain allergens étiquetables.
How a product is hypoallergenic it is best suited to the skin ?
Precisely because the allergens are molecules that are not present in the skin. It is able to accommodate most of the time, but they can sometimes be a source of allergic reactions, especially for sensitive skin. It is important to be able to offer these skins more fragile care without allergens with respect to their integrity.
Have you encountered difficulties to formulate in organic hypoallergenic ?
The specifications of formulation bio is already binding, but it has the advantage of guaranteeing the absence of substances widely used in conventional cosmetics, but considered as doubtful and potentially dangerous for the health (phenoxyethanol, paraben, chemical filters etc.) or other preservatives and highly allergenic (methylisothiasolinone and mathylchlorisothiasolinone).
Add to that specification, the constraint of hypoallergenicity has been complicated, in particular on the choice of the preservative system. Indeed, benzyl alcohol is one of the preservatives used in organic cosmetics because it is effective, authorized by the charter the Ecocert and it is very well tolerated. But it is part of the list of 26 allergenic molecules fragrances and although classified as low-allergenic, it has no place in a formulation that is hypoallergenic. The challenge therefore lies in the discovery of a preservative system effective, well tolerated and without allergens étiquetables. Mission accomplished for Thermal Water Jonzac with its preservative system patented.
Another impressive feat is to obtain a natural scent (no synthetic fragrances in cosmetics organic !), allergen-free étiquetables, but that is very sensory. A real headache !
In short, the formulation of effective healthcare and sensory organic and hypoallergenic is a real know-how of formulation.
Organic and hypoallergenic, what this cosmetic is even more affinitive ?
A care that is hypoallergenic is designed to reduce the risk of allergic reactions. So it does not contain ingredients with allergenic potential for known, and this fact respects the integrity of the skin which will be able to receive this care without allergic reaction (even if zero risk does not exist).
Add to this the many virtues of organic cosmetics ; care guaranteed to be free of molecules that are controversial or doubtful, no assets from the chemistry heavy, not very respectful of the skin. Let’s take the example of the Methilysothiazolinone, this molecule, which has appeared recently in conventional cosmetics to replace the parabens and which dermatologists are well aware of the effect very allergenic. Organic cosmetics guarantee the absence of these ingredients. It is in this way that it is more affinitive with the skin.
Thehas organic cosmetics and hypoallergenic it can stay in the sensory ?
It was a real challenge for us ; to realize products that remain pleasant to use with a sensor that defies the conventional. But, as often, the constraints and problems allow a good deal of progress !
The suppliers of raw materials have made huge progress and can now accompany us in this challenge which is to make the cosmetics organic, hypoallergenic, and sensory.
Thermal water Jonzac, are very sensory textures, soft, enveloping creamy and very pleasant to use. The fragrances are subtle and delicate. We never tire of it !
And this is real advances in organic cosmetics.
