COSMOS Chemical Reactions

Allowed physical processes:

• Extractions must use natural materials with any form of water or with a third solvent of plant origin such as ethyl alcohol, glycerin, vegetable oils and CO₂ absorption (on an inert support that conforms to these standards);
• Bleaching or deodorization (on an inert support conforming to these standards);
• Grinding, centrifuging (solid/liquid separation, spin-drying);
• Settling, decanting, desiccation or drying (progressive or not by evaporation/natural under sun);
• Deterpenation (if fractionated distillation with steam);
• Distillation, expression or extraction (steam);
• Filtration and purification (ultra filtration, dialysis, crystallization and ion exchange);
• Lyophilization, blending, percolation, cold pressure and hot pressure (depending on the fluidity of the fatty acids to be extracted);
• Sterilization with thermal treatments (according to a temperature respectful of the active substances); and
• Sifting, maceration and ultrasound

Allowed chemical processes:

• Alkylation, amidation, calcination of plant residues and carbonization (resins, fatty organic oils);
• Condensation/addition, esterification, etherification and fermentation (natural/biotechnological);
• Hydration, hydrogenation, hydrolysis and neutralization (to obtain Na, Ca, Mg and K salts);
• Oxidation/reduction processes for the manufacture of amphoterics; and
• Saponification, sulphation and roasting

Unallowed processes:
Any other processes that are not listed above are not allowed, including but not limited to:

• Bleaching or deodorization (on a support of animal origin);
• Use of enzymes derived from GMOs;
• Deterpenation (other than with beam);
• Ethoxylation, irradiation and sulphonation (as the main reaction);
