DYES OF VEGETABLE ORIGIN AND THEIR APPLICATION IN PAINTED COMPOSITIONS, IN PARTICULAR IN COSMETIC COMPOSITIONS

摘要

1. A dye of plant origin, characterized in that it is obtained from the painted part of plant species, the cellular tissues of which contain iridisomes, responsible for staining the specified part. ! 2. The dye according to claim 1, characterized in that it is obtained by the method according to which the specified part of the plant is subjected to surgery, during which the plant cells included in these cell tissues containing these iridisomes are at least partially separated in the presence of a liquid medium with the release of the colored product and its capture using the specified liquid medium. ! 3. The dye according to claim 2, characterized in that at least partial separation of the plant cells is carried out using at least one external energy source, in particular by mechanical stirring, for example using a magnetic stirrer, homogenizer or mill, or is carried out under the action of ultrasound in the presence of a liquid medium. ! 4. The dye according to claim 2, characterized in that the method also includes a filtering operation to release the product from at least a portion of the cellulosic residues. ! 5. The dye according to claim 3, characterized in that the method also includes a filtering operation to release the product from at least a portion of the cellulosic residues. ! 6. The dye according to claim 1, characterized in that said plant species is selected from the group consisting of plant species of the strelitzia family, in particular the plant species Ravenala madagascariensis, plant species of the Eleocarp family, for example Elaeocarpus angustifolius Blume, plant species of the aralia family, in particular vegetative
