Helianthus Annuus (Sunflower) Seed Oil
What is Helianthus Annuus (Sunflower) Seed Oil?
Helianthus Annuus (Sunflower) Seed Oil is extracted from the seeds of the sunflower plant (Helianthus annuus) and is widely used in skincare for its emollient and moisturizing properties. It is rich in essential fatty acids like linoleic and oleic acid, vitamin E, and phytosterols, which help nourish the skin and support its barrier function. The '0' in the query likely indicates a specific variant or concentration, but it refers to the standard INCI ingredient used in formulations.
Roles in Formulation
This ingredient serves the following purposes in cosmetic formulations:
Emollient
Softens and smooths skin by filling in surface roughness and improving slip; can also help reduce moisture loss when paired with occlusives and film formers.
Moisturising
Improves skin hydration and comfort by combining water-binding (humectant) and barrier-supporting (emollient/occlusive) mechanisms to reduce dryness.
Refatting
Replenishes lipids removed during cleansing to improve mildness and reduce tightness, leaving skin or hair feeling less stripped after rinse-off use.
Skin protecting
Forms a barrier to protect skin from external irritants.
Skin conditioning agent
Maintains skin softness, smoothness, and flexibility.
Antioxidant
Slows oxidation of oils, fragrances, and sensitive actives to improve shelf life and reduce rancidity or color change; sometimes also supports skin protection from oxidative stress.
