How are native cotton cells obtained?

The cotton comes from the cotton plant, a shrub belonging to the Malvaceae family, native to southern Africa. It is the plant fiber that envelops the seeds. To make it into fabric, the cellulose fibers that make up the cotton are isolated, pressed into bales, framed, spun, and woven. The remaining seeds are then processed to obtain clean cottonseed oil for consumption and used in some skin and hair care products. Worldwide, white cotton bales enjoy an image of a cocoon associated with a sense of well-being.

This pertains to whole cells locally harvested from the plant. They are derived from an environmentally friendly and biodiversity-respecting biotechnological process that involves several stages:

1. Selection of the Plant and Sampling : Collection of a piece of the plant (leaves) ;

2. Culture in vitro of the harvested plant piece: Successive transfers onto a fresh nutritive medium composed of water, minerals, sugar, and vitamins;

3. Elicitation: Stimulation of cell culture through UV and visible light to produce metabolites (active molecules);

4. Rinsing : Removal of all traces of the nutrient medium ;

5. Cell Filtration ;

6. Sonication of cells and dispersion of the extract in sunflower oil.

This technique aims to replicate and multiply cells from cell strains in a controlled environment. This process is not only beneficial for the ecosystem, but also allows for the preservation of all the plant's natural elements. Rich in essential amino acids, vitamins, and minerals, the cotton native cells thus obtained have a high molecular richness that provides them with a complementary action against other plant extracts (vegetable oils and essential oils).
