How we scored it
Extract of cultured Hippophae rhamnoides callus cells: cell biomass components (sugars, proteins, lipids, polyphenols) all n=1; culture-medium plant-growth regulators are reagents that leave no mass. 1.0.
What counts. ISO 16128-2 scores the atoms that remain in the final ingredient. Reagents, solvents, catalysts and protecting groups used during manufacture leave no mass behind and are not counted.
Where it comes from
Dominant route is plant cell culture, where sea buckthorn callus is grown in a sterile sugar-and-mineral medium, then harvested and extracted. The alternative of extracting field-grown shrubs would be a different INCI ingredient.
In plain English
An extract of sea buckthorn plant cells grown in laboratory culture rather than harvested from shrubs. It is listed for skin and hair conditioning, humectant (water-holding), antioxidant and antimicrobial functions, and it is made entirely from plant cells.
CosIng definition: Hippophae Rhamnoides Callus Extract is the extract of the callus of Hippophae rhamnoides grown in culture, Elaeagnaceae.
