Sunscreen and coconut allergy: it's the base, not the filter

A sunscreen is two things in one bottle. The active ingredients are the UV filters that do the protecting. Everything else is the base: the water, oils and emulsifiers that turn the filters into a lotion you can spread [1].

With a coconut allergy, the base is the part to read.

The filters

These are the active ingredients on sunscreens sold in the United States [1]:

• Mineral: zinc oxide, titanium dioxide
• Chemical: avobenzone, homosalate, octisalate, octocrylene, octinoxate, oxybenzone, and a few less common ones

None is named for coconut, and we found no source describing any of them as made from it. Zinc oxide and titanium dioxide are inorganic minerals, with no plant in them.

So "which filter?" is the wrong question for this allergy. It matters for other allergies, which we come to below.

The base

This is where the names from the rest of this site turn up.

On the label	What it is
Cocos nucifera (coconut) oil	Coconut oil
Caprylic/capric triglyceride	Made from coconut oil [2]. The commonest one in sunscreen.
Coco-caprylate/caprate	Esters of coconut alcohol [3]
Coco-glucoside	Coconut alcohol joined to glucose [4]
Coconut alkanes	Hydrocarbons made from the fatty acids of coconut oil [5]
Cetearyl alcohol, glyceryl stearate, stearic acid, isopropyl palmitate, PEG-100 stearate	Made from fatty acids whose plant the label doesn't name
C12-15 alkyl benzoate	The source of its alcohol isn't stated in the industry's review [6]
Caprylyl glycol	Commonly synthetic; plant-based versions exist. More

The first five count as coconut on this site. The rest are "can't be verified".

What 21 sunscreen lotions list

All read from the US drug-label database, DailyMed, in October 2026 [7]. Each is one specific product and SPF; other versions of the same brand differ.

No coconut ingredient named, and no caprylic/capric triglyceride:

• Neutrogena Ultra Sheer Dry-Touch SPF 45
• Banana Boat Ultra Sport SPF 50
• Coppertone Sport SPF 60
• Coppertone WaterBabies SPF 50
• Coppertone WaterBabies Pure & Simple Mineral SPF 50
• Sun Bum Original SPF 30
• Aveeno Protect + Hydrate SPF 60
• CeraVe Hydrating Mineral Sunscreen SPF 30
• Cetaphil Sheer Mineral Sunscreen SPF 50
• Blue Lizard Sensitive SPF 50
• Badger Adventure Sport Mineral SPF 50, whose entire inactive list is sunflower oil, beeswax and vitamin E

Most of these still list "can't be verified" names: glyceryl stearate, cetearyl alcohol, caprylyl glycol. Badger lists none of those either, and of the names in the table above Coppertone WaterBabies lists only C12-15 alkyl benzoate.

Caprylic/capric triglyceride:

• Banana Boat Sport Mineral SPF 50 (second ingredient after water)
• Thinkbaby SPF 50 (second after water)
• La Roche-Posay Anthelios Melt-in Milk SPF 60
• Supergoop Unseen Sunscreen SPF 40 and SPF 50

Coconut by name:

• Hawaiian Tropic Mineral Skin Nourishing Milk SPF 50: coconut oil, and caprylic/capric triglyceride second after water
• Sun Bum Mineral SPF 30: coconut oil second after water, and coco-glucoside
• Babo Botanicals Sheer Zinc SPF 30: coconut oil and coco-glucoside
• Hawaiian Tropic Weightless Hydration SPF 30: coco-glucoside
• Vanicream Facial Moisturizer SPF 30: coco-caprylate/caprate
• EltaMD UV Clear SPF 46: "PEG-7 trimethylolpropane coconut ether"

Three more mineral sunscreens we read for comparison: Babo Botanicals Hydrating Milk (caprylic/capric triglyceride, coco-caprylate/caprate), Pipette Mineral SPF 50 (caprylic/capric triglyceride, coco-glucoside), and Thinksport, whose own label reads "sorbitan stearate (coconut based)" [7].

"Mineral" is about the filter

Look at where the coconut is in those lists. Of the ten products with "mineral" in their name, six list coconut oil, caprylic/capric triglyceride or a coco- ingredient. Of the baby and family brands we read (Thinkbaby, Babo Botanicals, Pipette, Coppertone WaterBabies), the first three list one.

That isn't because zinc needs coconut. The Badger label shows a mineral sunscreen made with sunflower oil and beeswax, and four of the ten mineral ones list no coconut ingredient.

These are labels we chose to read, not a survey of the market. They are enough to say that "mineral", "baby" and "sensitive" on the front are not a shortcut, in either direction.

One brand, two answers

Sun Bum smells of coconut and banana, and its Original SPF 30 lists no coconut ingredient. Its Mineral SPF 30 lists coconut oil second. Banana Boat's Ultra Sport lists none; its Sport Mineral lists caprylic/capric triglyceride second [7].

Across all 57 Hawaiian Tropic labels in the database, coconut oil is on the tanning oils, the dry oil sprays and the mineral milk; coco-glucoside is on several of the lotions; and the clear sprays and mists list no coconut-named ingredient [7].

The scent on the front tells you nothing. The format tells you a little.

The coating on mineral filters

Zinc oxide and titanium dioxide particles are often coated so they spread evenly. The EU's scientific committee lists the coatings used: silica, alumina, dimethicone, stearic acid, glycerol and triethoxycaprylylsilane, among others [8].

Triethoxycaprylylsilane appears on eight of the labels above. "Caprylyl" means an eight-carbon chain; we found no source saying where that chain comes from. Our checker doesn't flag it. One label, Badger's, states that its zinc oxide is uncoated [7].

Tanning oil, after-sun and lip balm

Tanning oils are where coconut oil is the selling point:

• Hawaiian Tropic Protective Tanning Oil SPF 15, Hawaiian Tropic Island Tanning Oil SPF 6, Banana Boat Deep Tanning Oil SPF 4 and Sun Bum Tanning Oil SPF 15 all list coconut oil [7]
• Sun Bum's also lists sweet almond and macadamia oils, worth knowing if tree nuts are your other allergy

After-sun is easier. Sun Bum's Cool Down lotion and gel and Australian Gold's aloe gel list no coconut ingredient [7, 9], and the after-sun gel in our registry is one of the products with no coconut listed. Cocoa butter, on several of these labels, is not coconut.

Lip balm with SPF is the one you swallow:

Lists coconut oil or caprylic/capric triglyceride	Lists neither
Banana Boat Sport lip balm SPF 50 (both; the triglyceride is first)	Coppertone Sport lip balm SPF 30
ChapStick Active 2-in-1 SPF 25 (both)	Blistex Medicated Lip Balm SPF 15
Hawaiian Tropic lip balm SPF 30 (hydrogenated coconut oil)	ChapStick Moisturizer Original SPF 15
Sun Bum lip balm SPF 30 (the triglyceride)
Blistex Five Star SPF (the triglyceride)

All read from the label records [7]. Sun Bum's "Coconut" flavour lists no coconut oil. More on lip balm.

Makeup and moisturiser with SPF follows the same rules as any sunscreen. The BB cream in our registry sits at "can't be verified".

If sunscreen gives you a rash

Coconut is not the usual reason. DermNet's summary is that many sunscreen allergies are caused by the inactive ingredients, such as fragrances and preservatives [10].

• Among the filters, oxybenzone (benzophenone-3) is the leading cause of both allergic and sun-triggered reactions [11]. In a North American study of nearly 24,000 patch-tested patients, sunscreen was the source in 0.9%, and oxybenzone was the commonest allergen in it [12].
• Octocrylene reactions are mostly sun-triggered, and mainly in adults who have used the anti-inflammatory gel ketoprofen [13].
• In the base, a 2024 review lists emollients, emulsifiers, preservatives, perfumes and the cleansers decyl glucoside and lauryl glucoside [14]. Those two are made with an alcohol from coconut or palm oil [4], and they are the nearest thing to a coconut link in the literature: published cases exist, including one from a sunscreen [15].
• Coconut oil and caprylic/capric triglyceride: we found no published report of a sunscreen reaction traced to either.

A rash that appears only where sun and sunscreen met is a different thing from one that appears wherever the product went, and telling them apart takes photopatch testing. That is a dermatologist's job. The two kinds of coconut allergy.

The label depends on the country

Sunscreen is regulated differently from place to place, and that changes what you are allowed to see.

United States. An over-the-counter drug. The Drug Facts panel names the active ingredients and lists the inactive ones, and the labels are public on DailyMed [1, 7].

European Union and United Kingdom. A cosmetic. The full ingredient list must be on the packaging, in descending order of weight down to 1% [16].

Canada. A non-prescription drug or a natural health product, depending on the filter. Either way the non-medicinal ingredients must be listed on the outer label [17].

Australia. A therapeutic good. The label must name the active ingredients and certain declarable substances; the rule doesn't require every other ingredient to be listed [18]. The label does have to carry the contact details of the company responsible, and that is who to ask. One detail from the same rule: where it requires tree nuts to be declared, it notes that coconut is not considered a tree nut [18].

What to do

• Read the inactive ingredients, not the front. Scent, "mineral", "baby", "sensitive" and "reef-friendly" don't tell you.
• Look for Cocos nucifera, caprylic/capric triglyceride, coco-caprylate, coco-glucoside and coconut alkanes.
• Compare within the brand. The same brand's regular and mineral versions gave opposite answers twice.
• Check the lip balm separately. It is the one that gets eaten.
• Look it up before the holiday. Buying sunscreen on arrival, in a hurry, is how people end up with the wrong one. Travelling with a coconut allergy.
• Photograph the label and the checker marks every name on this page.
