As it has good levels of Omega 7 which is not very common in vegetable oils, it will hydrate the skin very well and lock moisture in to keep it supple and flexible.
It is anti inflammatory and helps to soothe dry and irritated skin conditions restoring elasticity and comfort to the area.
Palmitoleic acid is found in young people’s skin but levels diminish drastically as we age. Macadamia Nut Oil is a rich source of this antioxidant acid and tones aged or very dry skin to restore a youthful appearance. It decreases the depth of wrinkles by cellular regeneration and also diminishes rough skin.
The oil feels extremely rich and sinks into the skin slowly making it idea for massage oil blends and massage creams. It leaves the skin feeling very soft and smooth.
One of the first choice oils to use with mature and very dehydrated skin types. It is even better when blended with Omega 3 oils to enhance the absorption.
Emollient and protective to the skin and enhances the lipid barrier improving hydration levels. Works very well with Jojoba Oil for this purpose.
By conditioning the scalp, dandruff will be reduced. I also helps keep the hair soft and thicker without feeling sticky.
Regular use of the oil in hair products helps the hair to hold its sheen for longer with a more glossy appearance.
It makes dry, curly hair much more flexible and easier to manage.
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 Kiwi Seed Oil to for mature and very dry skin types. Use in rich night creams or serums.
If you like a very rich oil blend for your skin, combine with Avocado Oil or Avocado Butter along with 3% Vitamin E.
None, unless you have a nut allergy.

Heat Stage 1 (fat stage) in a stainless steel bowl on a double boiler until the temperature is above 75°C.
When Stage 1 (fat stage) is at temperature, add Stage 2 (water stage) ingredients into a larger stainless steel bowl or beaker.
Pour Stage 1 into Stage 2 and use a stick blender (high shear) to emulsify the two stages. This will happen in just a few seconds so keep checking. Ensure the temperature is above 75°C. When you lift the stick blender out of the mixture, the mix running off the blender head should look like a thin cream. If it looks granular or like it is separating, it needs more high shear blending.
When it has emulsified, take it out of the double boiler and use a spatula to stir it whilst it is cooling down. You can use a cold water bath to speed up the cooling. Do not continue to use the stick blender as this will destroy the liquid crystal structure that the emulsification has formed.
When it is under 40°C, dissolve the Vitamin B3 in the Comfrey Glycerol Extract, then add the remaining Stage 3 (heat sensitive) ingredients. Combine thoroughly, jar and label.
