Is safflower oil worse than sunflower oil?

Conventional safflower is slightly higher in linoleic acid than conventional sunflower, and both are far higher than canola or olive. That is a composition comparison, not a demonstrated health ranking.

Is high-oleic safflower oil acceptable on a seed-oil-free diet?

It depends which objection you hold. On linoleic acid it looks closer to olive oil; on solvent extraction and refining it is identical to the conventional version. The community is genuinely split on this.

Is safflower the same as sunflower?

No. They are different plants — safflower is a thistle relative, sunflower is Helianthus — though their oils are marketed similarly and both come in high-linoleic and high-oleic forms.

Answer

Is safflower oil a seed oil?

Short answer

Yes. Safflower oil is pressed from the seeds of Carthamus tinctorius, a thistle-like plant, which makes it a seed oil under every definition. Conventional safflower oil is roughly 75% linoleic acid — among the highest of any culinary oil — while the high-oleic cultivar sold under the same two words is roughly 75% oleic instead.

The same trap as sunflower

Safflower and sunflower share a problem: one name covering two oils with almost inverted fatty-acid profiles, and no requirement to say which is in the bottle.

High-linoleic safflower: roughly 75% linoleic acid, historically the standard version
High-oleic safflower: roughly 75% oleic, linoleic often under 15%
High-oleic is now the more common one in US foodservice, because it survives frying temperatures better

Why it turns up in 'natural' products

Safflower oil has a long run as a health-food-aisle oil, dating to the period when a high polyunsaturated share was itself the selling point. That history is why it still appears in products whose positioning is otherwise natural or clean — snack bars, chips, nut butters, infant formula.

Whether the omega-6 share is a problem is exactly the argument the seed-oil debate is about, and it is not resolved by either side's confidence. What is not in dispute is the composition, which is why a scanner can report the ingredient without taking a position on the outcome.

Reading it on a label

'Safflower oil' alone means the conventional kind more often than not. Manufacturers using the high-oleic version usually declare it, because it costs more and reads better on a spec sheet. Olive Detective flags safflower oil when it appears and records the cultivar only when the label states it.
