- Read the ingredient list (INCI) – what counts is the name, the order and any additives.
- Traditional use is not proof of a medical effect.
- With “Brazilian straightening”, watch for formaldehyde and formaldehyde releasers.
- Test new products first on a small patch of skin.
Reading labels: what the list reveals
Cosmetics list their ingredients in the INCI list, in descending order by quantity. If a plant fat is right at the front, it is the main component. If fragrances and alcohol appear early in the list, they predominate.
- Cupuaçu butter: “Theobroma Grandiflorum Seed Butter”
- Andiroba oil: “Carapa Guaianensis Seed Oil”
Cupuaçu butter
Cupuaçu (Theobroma grandiflorum) is related to the cacao tree. The butter from the seeds is soft, creamy and valued for its smooth skin feel. It is used in body butter, lip care and hair care.
- Unrefined has a slightly nutty-chocolatey scent and retains more of its accompanying compounds.
- Refined is odour-neutral and usually lasts longer.
Andiroba oil
Andiroba (Carapa guianensis) is an Amazon tree whose seed oil is traditionally used in many ways in the region. It has an intense smell and tastes bitter. Use sparingly on skin, and look for products diluted in a carrier oil.
Important: Claims about insect protection or wound healing come mainly from tradition. Andiroba oil is no substitute for an approved repellent, and if you have skin problems, ask a dermatologist if in doubt.
Brazilian hair masks and “keratin straightening”
“Brazilian” on a hair product says nothing about the formulation. Some masks only condition (oils, butter, proteins), others promise straightening.
Tolerability and shelf life
- Patch test: Apply a small amount in the crook of your arm and watch for 24–48 hours. Do not use if there is redness, itching or burning.
- Fragrances: Certain fragrances must be declared (e.g. limonene, linalool). Allergy sufferers should check the list.
- Shelf life: The symbol with the open jar shows how long the product can be used after opening. Natural oils can oxidise – store cool and dark.
Origin and sustainability
Pictures of rainforest and cooperatives are just marketing unless they are backed up. Helpful signs are traceable origin information, recognised certifications and transparency from the seller. A single seal is no proof – it pays to look at several signals.

Frequently asked questions
Is unrefined butter always better?
Not necessarily. It retains more natural compounds but smells stronger. Refined butter is more neutral and can be more pleasant for people sensitive to fragrance.
How long does cupuaçu butter keep?
It is stated on the pack (best-before date and PAO symbol). Stored cool and dark, it lasts longer.
Are silicones in hair masks bad?
Not inherently. They smooth and protect, but can build up with frequent use. That is a matter of taste and depends on hair type.
