Iris germanica root extract is obtained from Iris germanica (a plant belonging to the botanical family Iridaceae) known for its beautiful and striking flowers. In addition to its ornamental use, the root of this plant, often referred to as Orris root, has been valued in various cultures for its fragrance and medicinal properties. The root extract is particularly valued in perfumery and cosmetics.

Name breakdown and function of the components

• Iris germanica - This is the scientific name for the German Iris or Bearded Iris, a perennial ornamental plant.
• Root - Refers to the underground part of the plant. The roots of Iris germanica contain compounds such as iridins, mucilages, and other bioactive components.
• Extract - Indicates that the product is a concentration of some components of the root.

Description and function of the raw materials used in production

• Iris germanica roots - The primary source of iridins, mucilages, and other beneficial compounds.
• Solvent (like water or ethyl alcohol) - Used to extract the beneficial compounds from the roots.
• Summary of the extraction process step by step

Collection and preparation of the roots - Roots are harvested and cleaned from impurities.

• Shredding - The roots are shredded into smaller pieces to increase the surface area in contact with the solvent.
• Extraction - The shredded material is soaked in the solvent for a specified period, allowing the compounds to diffuse into the solvent.
• Filtration - Once extraction is complete, the solution is filtered to remove any residual solid particles.
• Evaporation - The solvent is then evaporated, leaving behind the concentrated Iris germanica extract.
• Stabilization and preservation - The extract may be further treated or stabilized for long-term storage.

The most important function of the conditioning agent is to prevent skin dehydration, but the subject is rather complex and involves emollients and humectants that can be added in the formulation.
