Where coconut hides

On food, coconut is usually easy to spot: coconut oil, milk, flakes, sugar. On cosmetics it’s a different story. Soap, shampoo, body wash, creams and makeup often contain ingredients made from coconut oil whose names don’t say so.

Made from coconut

These ingredients are coconut-derived by name or by how they’re made:

On the label	Where you’ll find it	Why it’s coconut
Sodium cocoate	bar soap	the salt of fatty acids from coconut oil: this is “coconut soap” [1]
Cocamidopropyl betaine	shampoo, body wash, baby wash	made starting from coconut fatty acids [2]
Cocamide DEA	hand soap, dish soap	a derivative of coconut oil [3]
Coco-glucoside	“natural” and baby cleansers	made from coconut alcohol and glucose [4]
Caprylic/capric triglyceride	creams, sunscreen, makeup	traditionally made by splitting coconut oil [5]

Anything starting with coco- or cocam- is a good clue. The full list, in English and Spanish, is on the coconut’s names page.

Coconut or something else: you can’t tell

Some very common ingredients can be made from coconut or from other oils, and the label doesn’t say which. On this site they get an amber flag:

• Glycerin: made from many different fats and oils, or synthetically, and labelled “glycerin” either way [6].
• Sodium lauryl sulfate (SLS) and sodium laureth sulfate (SLES): made from lauryl alcohol, which can come from coconut oil or from petrochemicals [7].
• Decyl and lauryl glucoside: their fatty alcohols can come from coconut oil or palm oil [4].
• MCT oil (medium-chain triglycerides): found in coconut oil, palm kernel oil and milk fat, or made synthetically [8].

When it matters, the only way to know is to ask the maker. That’s why we write to brands and publish their answers.

Why the label doesn’t tell you

Cosmetic labels must use standard ingredient names (called INCI names in the EU), not the plant they came from [9]. So “glycerin” from coconut and “glycerin” from palm look exactly the same.

Food, formula and medicines

• Infant formula: coconut oil is a known fat source in some formulas, and there is at least one published case of an infant reacting to coconut oil in formula [10].
• Medicines: we haven’t found reliable reports of reactions to coconut in medicines. If you’re worried about a specific medicine, ask your pharmacist about its inactive ingredients.

Two places people forget

Medicines carry inactive ingredients too, and some are coconut-derived: see coconut in medicines. Fragrance is its own puzzle, because the bottle often has no list at all: see perfume, body mist, roll-on.
