The biological calculation excludes water and minerals. Within the standard, limitations are placed on methodologies, processes of chemical synthesis and on the transformation of natural products (of vegetable, animal or microbial origin) used. The extraction processes used must be included in a specific list attached to the specification.

The use of raw materials obtained from animals or plants appearing on European and International lists of protected species is prohibited.

Milk, honey, wax and other ingredients of animal origin produced by the same animals and not derived from their killing or suffering may be used.

Unlike food products, in the cosmetic sector there is no regulation that establishes what is a biological and/or natural cosmetic.

Certification becomes, therefore, a voluntary choice pursued by the most evolved and virtuous companies that feel the need to provide customers with greater guarantees, subjecting themselves to the controls of an independent and professional organization that guarantees their correct operation and the ecological qualities of the products.
