Like all natural and organic products, NATorigin respects the environment. However the formulation and preparation of NATorigin products goes much further in order to meet the standards of Allergy Specialists and Dermatologists.
The key is the Bio-inertia of formations, for more information read the Why choose NATorigin section.
Some essential ingredients do not have a suitable natural alternative (e.g. sodium hydroxide as a pH adjuster). We use a chemical buffer (phosphate) because natural buffers (citric acid/sodium citrate) are less well tolerated by sensitive skin and eyes. It is sometimes better to use a very small amount of an effective chemical product than a lot of an ineffective natural one.
Certain natural ingredients (preservatives, essential oils, pigments, etc) often used in organic/natural products are not used in the NATorigin range at the request of Allergy Specialists or Dermatologists in order to reduce the risk of reaction. Some preservatives authorized by natural and organic standards are synthetics but we believe are unsuitable (e.g. benzoic acid).
The entire NATorigin range can be considered nickel free.
Some products (mascaras, liners) do contain iron oxides which can contain nickel as a contaminant. We use as pure a form of iron oxide as possible (nickel content less than 1ppm) and also the minimum amount necessary. Therefore, even if someone has a nickel allergy, they are unlikely to have a reaction due to this.
