What it is
In the register’s words: “Helianthus Annuus Seed Oil is the fixed oil expressed from the seeds of the sunflower, Helianthus annuus.”
- EU register name (INCI)
- HELIANTHUS ANNUUS SEED OIL
- CAS number
- 84776-03-4 (generic)/ 8001-21-6/ 164250-88-8 (generic)
- EC number
- -/ 232-273-9/ -
Labels often add a second name in brackets, so a label may say Helianthus Annuus (Sunflower) Seed Oil where the register says HELIANTHUS ANNUUS SEED OIL. Both are the same ingredient.
What the register lists it for
These are the uses the European Commission’s CosIng register lists for Helianthus Annuus (Sunflower) Seed Oil in any cosmetic, hair roles first. They say why a maker might add it, not what it does in one formula, and they aren’t a safety rating.
- Emollient
-
Oils, butters and similar ingredients that make a surface feel soft and smooth. On hair they coat the strand; many plant oils carry this role.
Register definition: “Acting as lubricants on the skin surface providing the skin with a soft and smooth appearance.”
- Solvent
-
Dissolves other ingredients. Water is the most common; some alcohols and glycols carry this role too.
Register definition: “Dissolving other components of cosmetics. Solvents are usually liquids (aqueous and nonaqueous).”
- Occlusive
-
Forms a layer that slows water loss. Heavier oils, butters and waxes carry it.
Register definition: “Retarding the evaporation of water from the skin surface. Occlusives are generally lipids which tend to remain on the skin surface and thus increase the water content of skin.”
- Skin conditioning
-
A register role for ingredients that help dry or rough skin feel supple again.
Register definition: “Enhancing the appearance of dry and/or damaged skin by reducing flaking and restoring suppleness.”
Where it sits on each label
US labels list ingredients from most to least, except that those at 1% or less may follow in any order. A name near the top is a large part of the formula. A label doesn’t mark where the 1% point falls, so further down, the order says little about how much is in it.

Each line runs from the first name on a label to the last; a dot is where this ingredient sits. Makers change formulas now and then; if the list on your bottle differs, go by your bottle.
