Peanut Oil, also known as Groundnut Oil, is a botanical fixed oil obtained from the seeds or kernels of Arachis hypogaea L., a legume belonging to the Fabaceae family. In cosmetic formulations, Peanut Oil is used primarily as an emollient and skin-conditioning ingredient and can also provide hair-conditioning and formulation-support properties.
Peanut Oil contains a mixture of triglycerides with oleic acid, linoleic acid and saturated fatty acids as important components. The exact fatty acid profile depends on the peanut variety, growing conditions, extraction method, refining process and commercial grade.
Cosmetic-grade Peanut Oil is generally supplied as a pale-yellow to yellow oily liquid. It can be incorporated into skincare, body-care, haircare, massage, lip-care and other oil-containing formulations.
The cosmetic ingredient discussed on this page is Arachis Hypogaea Oil, which should be distinguished from peanut protein, peanut extract and other peanut-derived cosmetic materials.
Peanut Oil is a fixed vegetable oil obtained from the seeds or kernels of Arachis hypogaea L. through suitable mechanical or extraction processes. Refined cosmetic grades may undergo additional purification and processing to achieve controlled colour, odour and quality characteristics.
INCI Name: Arachis Hypogaea Oil

Common Names: Peanut Oil, Groundnut Oil
Family: Fabaceae

Product Type: Botanical Fixed Oil
Physical State: Liquid
Peanut Oil is a complex mixture rather than a single chemical compound. Its triglycerides contain different fatty acids, with oleic and linoleic acids generally representing important unsaturated components.
The oil is essentially insoluble in water and is compatible with suitable cosmetic oil phases.
Peanut Oil is composed primarily of triglycerides formed from glycerol and fatty acids. The exact molecular composition is not fixed because natural vegetable oils contain mixtures of triglycerides.
Important fatty acids associated with Peanut Oil include:
The ratio between oleic and linoleic acid can vary significantly between conventional and high-oleic peanut varieties. Therefore, a guaranteed fatty acid percentage should be taken from the current COA or technical specification of the supplied grade.
Peanut Oil is primarily used as an emollient and skin-conditioning cosmetic ingredient.
Peanut Oil contributes to a smooth and soft skin feel and can help improve the sensory characteristics of creams, lotions, balms and oil-based formulations.
It is used in cosmetic products designed to maintain a conditioned and comfortable skin feel.
Peanut Oil can be incorporated into hair oils, masks, conditioners and other oil-containing haircare formulations where a botanical emollient is desired.
Peanut Oil can contribute to the oil phase of emulsions and can be used directly in anhydrous cosmetic systems.
Its lipid character makes it suitable for blending with other vegetable oils, esters, waxes and oil-soluble cosmetic ingredients.
Peanut Oil provides a plant-derived lipid for botanical and naturally positioned cosmetic formulations.
Peanut Oil has a characteristic fatty acid profile containing both monounsaturated and polyunsaturated fatty acids.
The principal fatty acids generally associated with Peanut Oil include:
High-oleic peanut oil grades can have a substantially different oleic-to-linoleic ratio from conventional Peanut Oil.
For formulation qualification, the actual fatty acid profile should be verified from the commercial grade's COA or TDS rather than assuming one universal composition.
Depending on the extraction and refining process, Peanut Oil may contain naturally occurring minor components such as:
Refined and unrefined Peanut Oil can therefore differ in colour, odour, oxidative stability and minor-component content.
Peanut Oil can be considered for a broad range of cosmetic and personal-care formulations.
Potential applications include:
Peanut Oil can be incorporated into:
Applications can include:
Where suitable for the intended product and regulatory requirements, Peanut Oil may be incorporated into:
Peanut Oil contains unsaturated fatty acids, so exposure to excessive heat, oxygen and light should be controlled during storage and formulation.
Refined, cold-pressed and other Peanut Oil grades can differ significantly in colour, odour, fatty acid profile and minor constituents. The intended cosmetic application should determine the appropriate grade.
Peanut is a recognized food allergen. Cosmetic formulations containing Peanut Oil require appropriate regulatory and safety assessment, particularly where the oil is unrefined or may contain residual peanut proteins.
The allergen-related characteristics of a refined oil cannot automatically be assumed from those of an unrefined or cold-pressed grade. Buyers and formulators should obtain the relevant allergen/protein information and processing documentation for the actual commercial grade.
Peanut Oil is essentially insoluble in water and should generally be incorporated into the oil phase of emulsions or directly into anhydrous formulations.
Important quality parameters may include:
Batch-specific values should be confirmed using the current COA and TDS.
Store Peanut Oil in a tightly closed container under the conditions recommended for the selected commercial grade. Protection from excessive heat, light and oxygen is recommended to help maintain quality.
Peanut Oil should not be confused with Peanut Extract.
Peanut Oil is a fixed botanical oil consisting predominantly of triglycerides and is used mainly for emollient and conditioning functions.
Peanut extracts can contain different classes of compounds depending on the plant part and extraction method. They therefore have different INCI identities, specifications and formulation characteristics.
For cosmetic documentation, the exact raw-material identity should always be confirmed.
Peanut Oil and Hydrogenated Peanut Oil are different cosmetic ingredients.
Peanut Oil / Arachis Hypogaea Oil is the non-hydrogenated botanical fixed oil.
Hydrogenated Peanut Oil is produced by hydrogenating peanut oil, which changes its physical and functional characteristics. Cosmetic databases separately identify Hydrogenated Peanut Oil and associate it with functions including skin conditioning, emolliency, emulsifying and viscosity control.
Therefore, the two ingredients should not be treated as interchangeable in product documentation.
Peanut Oil can be selected for cosmetic formulation development where a plant-derived fixed oil with emollient and conditioning properties is required.
Key product considerations include:
The botanical identity, processing method, allergen information, fatty acid profile and quality parameters should be verified for the selected commercial grade.
Swapnroop provides cosmetic ingredients for manufacturers, formulators and personal-care businesses developing skincare, haircare, body-care and other cosmetic products.
Peanut Oil can be considered for formulations requiring a plant-derived emollient and conditioning oil. For commercial procurement, buyers should review the applicable specification, COA, TDS, processing information, allergen documentation, packaging and storage requirements.

The main cosmetic functions include skin conditioning and emolliency. It can also be used for hair conditioning and formulation support.
Yes. It can be incorporated into creams, lotions, facial oils, body oils, balms and other skin-conditioning formulations, subject to appropriate safety and regulatory assessment.
Yes. Peanut Oil can be incorporated into hair oils, conditioners, masks and other hair-conditioning products.
Yes. Oleic acid is one of the important fatty acids associated with Peanut Oil. The exact concentration depends on the peanut variety and commercial grade.
