Oil-Free Sunscreen: What It Means, and How to Find One

Oil-free sunscreen is sunscreen made without plant oils, seed oils, butters, or mineral oil in the formula. It is not a regulated term, so the ingredient list is the only real proof. Swellies is an oil-free mineral sunscreen: the base is Coco Caprylate/Caprate, a lightweight ester, not an oil, and there are no seed oils, butters, or mineral oil anywhere in its five ingredients.

Is there oil in sunscreen?

Often, yes. Oils give a formula slip, make it feel moisturizing, and look good on a "natural" label. You will find them in plenty of mineral sunscreens in particular, because an oil is an easy way to help thick zinc spread. The common ones:

• Seed oils: sunflower, safflower, jojoba, raspberry, and grapeseed
• Fruit and nut oils: coconut, olive, avocado, and almond
• Butters: shea, cocoa, and mango
• Mineral oil: sometimes listed as paraffinum liquidum

If you are specifically avoiding seed oils, we cover that in seed oil-free sunscreen without the tallow.

Why people look for oil-free

• Oily skin. An oil in the base adds to the shine you are already fighting. See mineral sunscreen for oily skin.
• Acne-prone skin. Some oils and butters leave a film that acne-prone skin does not want. See sunscreen for acne-prone skin.
• Feel. A lot of people just do not want to feel greasy by lunch.
• Specific oils. Some people avoid one oil in particular. Sunflower seed oil is a common one.

Oils vs. esters

This is the part that confuses most labels. A sunscreen needs something to carry the zinc and spread it across your skin. That carrier can be an oil, or it can be an ester.

An ester is made by combining a fatty acid with an alcohol. The result behaves differently from the oil it may have started from: lighter, faster to spread, and far less greasy. It does not sit on your skin as a slick layer.

Coco Caprylate/Caprate, the carrier in Swellies, is one of these. It is made from coconut-derived ingredients, but it is not coconut oil. Oil-free and plant-derived are not opposites.

Some ingredients sit in between. Caprylic/capric triglyceride, for example, is sometimes marketed as fractionated coconut oil. It is not in Swellies, but it is worth knowing if you are reading other labels closely.

Water-free is not oil-based

Swellies is anhydrous, which means there is no water in the formula. People sometimes assume that means it must be an oil. It is not. The base is an ester and a plant-derived gel former, Dextrin Palmitate, which is why it wears as a lightweight gel. No water also means no preservatives, since there is nothing in the formula for anything to grow in.

How to read a label for oils

Ingredient lists use formal names, so oils do not always say "oil" plainly. Look for:

• "Oil" or "butter" anywhere in the name
• Latin plant names followed by seed oil or butter: Helianthus annuus (sunflower), Simmondsia chinensis (jojoba), Cocos nucifera (coconut), Butyrospermum parkii (shea), Theobroma cacao (cocoa)
• Paraffinum liquidum or mineral oil

Also check what the label claims. "Oil-free," "non-greasy," and "non-comedogenic" are three different things. A formula can be one without being the others. And "mineral" on the front says nothing about the base, where silicones often show up too. Here is where silicone hides.

Frequently asked questions

What does oil-free sunscreen mean?

Oil-free sunscreen is made without plant oils, seed oils, butters, or mineral oil in the formula. It is not a regulated term, so check the ingredient list for anything called an oil or butter.

Is there oil in sunscreen?

Many sunscreens contain oils, including sunflower, jojoba, coconut, and mineral oil, or butters like shea and cocoa. They add slip and a moisturizing feel. Oil-free formulas use other ingredients, such as esters, to carry and spread the sunscreen.

Is Swellies oil-free?

Yes. Swellies contains no oils, seed oils, butters, or mineral oil. Its carrier is Coco Caprylate/Caprate, a lightweight ester, and the formula is made of five ingredients: zinc oxide, Coco Caprylate/Caprate, Dextrin Palmitate, Polyhydroxystearic Acid, and Iron Oxides.

Is coco caprylate/caprate an oil?

No. Coco caprylate/caprate is an ester made from coconut-derived ingredients. Esters are lighter and less greasy than oils, which is why they are used in formulas that aim to be oil-free.

Is there sunflower oil in sunscreen?

Some sunscreens contain sunflower seed oil, often listed as Helianthus annuus seed oil. Swellies does not contain sunflower oil or any other seed oil.

Is oil-free sunscreen better for oily or acne-prone skin?

Many people with oily or acne-prone skin prefer oil-free sunscreen because it avoids adding a greasy film. Look for a formula that is also fragrance-free and labeled non-comedogenic, since oil-free alone does not cover everything.

Does water-free sunscreen mean it is oil-based?

No. Water-free, or anhydrous, only means the formula contains no water. Swellies is water-free and oil-free: its base is an ester and a plant-derived gel former, which is why it wears as a lightweight gel.
