How we scored it
Whole fixed oil expressed from rosehip seeds; entire triglyceride mass is botanical, no petrochemical fragment = 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
Expeller- or cold-pressed from the seeds of Rosa canina (dog rose) fruit, a byproduct of rosehip processing. No alternative synthetic route exists for this INCI.
In plain English
A light plant oil pressed from rosehip seeds, used to soften and condition skin. It's made from the seeds left over when rosehips are processed for fruit and tea.
CosIng definition: Rosa Canina Seed Oil is the fixed oil expressed from the seeds of Rosa canina, Rosaceae.
