Macadamia Nut Oil is a botanical cosmetic oil obtained from the kernels of macadamia nuts, primarily from Macadamia integrifolia and related Macadamia species. It is valued in personal-care formulations for its emollient, skin-conditioning and hair-conditioning properties.
The oil is naturally rich in monounsaturated fatty acids, particularly oleic acid and palmitoleic acid, with additional palmitic, stearic and linoleic acids. Its fatty acid profile gives Macadamia Nut Oil a smooth, nourishing sensory character that makes it suitable for skincare, haircare, body-care and specialty cosmetic formulations.
Macadamia Nut Oil is generally supplied as a liquid fixed vegetable oil. Its exact color, odor, fatty acid composition, oxidative stability and other quality parameters depend on the botanical source, extraction process, refining level and commercial grade.
Macadamia Nut Oil is a fixed vegetable oil produced by pressing or extracting the kernels of macadamia nuts. Unlike essential oils, it is a non-volatile lipid material composed predominantly of triglycerides containing naturally occurring fatty acids.
The oil is particularly recognized for its high proportion of monounsaturated fatty acids. Palmitoleic acid is one of its characteristic fatty acids and contributes to the distinctive composition of macadamia-derived oil.
In cosmetic formulations, Macadamia Nut Oil is primarily used as an emollient and skin-conditioning ingredient. It can help provide a smooth, conditioned skin feel and can contribute to the lipid phase of creams, lotions, facial oils, balms and other personal-care products.
Macadamia Nut Oil should not be confused with macadamia nut extract, macadamia fragrance materials or macadamia essential-oil-type products. The fixed oil is a lipid-rich material obtained from the nut kernel.

Macadamia Nut Oil functions primarily as an emollient, contributing to a smooth and comfortable skin feel. It can be incorporated into formulations designed to improve the sensory characteristics of the skin surface.
The oil is suitable for skin-conditioning formulations where a plant-derived lipid ingredient is required. It can be used in creams, lotions, facial oils, serums, balms and body-care products.
Macadamia Nut Oil can be incorporated into hair oils, conditioners, masks, leave-on treatments and other haircare formulations where an emollient botanical oil is desired.
As a fixed oil, Macadamia Nut Oil can form part of the oil phase of emulsions and can also be used in anhydrous formulations such as balms, body oils and oil-based treatments.
Depending on the formulation system and concentration, Macadamia Nut Oil can contribute to spreadability and a smooth, conditioned after-feel.
Macadamia Nut Oil has a distinctive fatty acid profile characterized by a high proportion of monounsaturated fatty acids.
Commonly associated fatty acids include:
The exact percentages can vary according to macadamia species, cultivar, geographical origin, maturity, extraction method, refining and storage conditions. For formulation qualification, the current batch COA should be used for the applicable fatty acid profile.
Depending on the processing method, Macadamia Nut Oil may contain naturally occurring minor lipid components such as:
Refined and unrefined grades can differ significantly in color, odor, oxidative stability and minor-component composition.
Macadamia Nut Oil can be used in a wide range of personal-care formulations.
Macadamia Nut Oil contains unsaturated fatty acids, so exposure to oxygen, heat and prolonged light should be controlled during storage and formulation.
An appropriate antioxidant system may be considered depending on the finished formulation, packaging and expected shelf life.
Avoid unnecessary prolonged exposure to high temperatures. Processing conditions should be selected according to the characteristics of the specific commercial grade.
Macadamia Nut Oil can generally be incorporated into suitable oil phases and anhydrous systems. Compatibility testing should be conducted with esters, hydrocarbons, waxes, emulsifiers and other lipid materials used in the formulation.
The color and odor can vary according to whether the oil is refined, deodorized, cold-pressed or otherwise processed. The selected grade should therefore be evaluated against the sensory requirements of the finished product.
Macadamia Nut Oil is derived from a tree nut. Manufacturers should evaluate applicable allergen, labeling, regulatory and raw-material handling requirements for the target market and finished cosmetic product.
Important quality parameters can include acid value, peroxide value, iodine value, saponification value, refractive index, relative density, moisture and fatty acid composition. The current COA and TDS should be used for commercial qualification.
Store in a tightly closed container under the storage conditions recommended for the applicable grade. Protection from excessive heat, oxygen and direct light can help maintain oil quality.
Macadamia Nut Oil is a fixed lipid-rich oil obtained from the nut kernel, whereas macadamia nut extracts can contain different classes of botanical constituents depending on the extraction method.
For cosmetic raw-material documentation, the correct material identity, INCI designation, botanical source and processing method should be confirmed before formulation.
Swapnroop provides Macadamia Nut Oil as a botanical cosmetic ingredient for cosmetic manufacturers, formulators and personal-care businesses requiring specialty plant-derived oils.
Macadamia Nut Oil can be considered for skincare, haircare, body-care, facial oil and other lipid-based cosmetic formulations.
For commercial procurement, buyers should verify the applicable botanical source, INCI identity, processing method, fatty acid profile, quality specifications, packaging, batch COA and technical documentation for the selected grade.
Macadamia Nut Oil is a fixed botanical oil obtained from macadamia nut kernels and used primarily as an emollient and skin-conditioning ingredient in cosmetic formulations.
The commonly used INCI name is Macadamia Integrifolia Seed Oil.
A commonly assigned CAS number for Macadamia Nut Oil is 128497-20-1.
Yes. Macadamia Nut Oil is normally supplied as a liquid fixed vegetable oil at typical ambient temperatures.
No. Macadamia Nut Oil is a fixed vegetable oil and is essentially insoluble in water.
Its primary cosmetic functions are emollient and skin conditioning, with additional applications in hair conditioning and oil-phase formulation support.
Macadamia Nut Oil commonly contains oleic acid, palmitoleic acid, palmitic acid, linoleic acid and stearic acid. Exact percentages depend on the commercial grade.
