What does this ingredient do in an antiperspirant?
According to CosIng, it is the fixed oil expressed from sunflower seeds. Its functions are emollient, occlusive and miscellaneous skin conditioning, and solvent.
Part of a system, not a label in isolation
In deodorants and antiperspirants, sunflower oil belongs to the skin care part of the base and softens application. It does not reduce sweating.
CIR assessed 244 plant-derived fatty acid oils, including sunflower seed oil, and concluded that they are safe as used in cosmetics.
It is generally well tolerated, but a plant origin does not rule out an individual reaction to the finished formula.
Helianthus Annuus Seed Oil is not the same as hydrogenated sunflower seed oil or sunflower seed extract: those are separate INCI entries.
