A clear to light yellow oil with quite a strong odour that is savoury and slightly spicy. You would need to use strongly fragrant essential oils if this does not appeal to you and you want to cover it.
What we commonly refer to as a Brazil Nut is in fact a seed and it is the seeds that are pressed to give this oil.
Bertholletia excelsa Seed Oil
According to the Cosmetic Ingredient Database (Cosing), the functions of Brazil Nut Oil are:
Emollient, Skin Conditioning

It is a natural emollient with a light texture that is quickly absorbed by the skin. Excellent for all skin types.
It leaves the skin soft and smooth and forms a protective layer that slows down TEWL (Transepidermal Water Loss). This prevents dehydration of the skin and keeps fine lines and wrinkles at bay. Use in age defying creams, lotions and serums.
Use in aftershave creams and aftershave balms to soften the skin and keep it hydrated. Also softens the beard stubble for the next time you shave.
Keeps the lips very pliable when used in lip balms. Prevents dry and cracked skin.
It contains phytosterols which are effective at calming down inflammation in the skin and stimulate the healing process. It also increases the speed of cell renewal.
It relieves itching and dryness so is very beneficial for eczema prone and psoriasis prone skin products.
The antioxidant content helps to reduce cell and tissue damage so use in products for acne prone skin.
Use in products for dry, brittle and damaged hair without any greasy after feel.
It is soothing for a sensitive or irritated scalp and improves the microcirculation. Its hydrating properties will diminish dandruff.
Use in hair conditioners and hair packs at 3% to 10% along with other hair appropriate oils.
Use 1% to 100%.
Oil soluble so cannot be used in water only products. It can be used in small amounts in water based gels that will hold it in suspension.
Heat stable so can be used in Stage 1 (fat stage) when making creams and lotions.
Blend with Shea Butter, Helichrysum Essential Oil with Lavender Essential Oil for eczema prone and psoriasis prone skin as well as anti ageing products.
This would also be ideal as a night balm for anyone with very dry or dehydrated skin.

Traditional Aromatherapy Uses
Traditionally used by qualified aromatherapists in treatment packs, ointments and balms for eczema and psoriasis. The selenium content is very high which is excellent for cell renewal.
Brazil Nut Oil has given the indigenous people of Brazil a secure income that does not depend of the destruction of the rainforests ecosystem as there is no logging involved. The Brazil Nut trees are valued and protected as each tree can yield about 50 litres of oil per year without damage.
Organic certification is a hard standard to achieve and wild harvested is more common to find.
