Description

Oils, Macadamia CAS NO 129811-19-4 is a premium natural oil derived from the nuts of the *Macadamia integrifolia* tree, valued for its high content of monounsaturated fatty acids, particularly palmitoleic acid. This composition makes it a highly stable and skin-compatible emollient, offering superior moisturizing and protective properties. It is an essential ingredient for manufacturers in the personal care, cosmetics, and nutraceutical industries seeking high-quality, natural lipid components.

Application

• Cosmetic & Skincare Formulations: As a key emollient and occlusive agent in moisturizers, creams, lotions, and serums for its excellent skin barrier repair and hydration properties.
• Hair Care Products: Incorporated into conditioners, hair masks, and serums to impart shine, reduce frizz, and protect hair from environmental damage.
• Pharmaceutical & Nutraceutical Carriers: Used as a carrier oil for lipid-soluble active ingredients in topical formulations and softgel capsules.
• Massage & Aromatherapy Oils: Serves as a premium base oil due to its non-greasy feel, excellent spreadability, and skin absorption.
• High-End Soap Making: Adds luxury conditioning properties and stable lather to specialty cold-process and melt-and-pour soaps.
• Natural Preservative & Antioxidant Blends: Its fatty acid profile contributes to the oxidative stability of formulations, potentially extending shelf-life.

Quality Control

Our Macadamia Oil is produced and tested to meet stringent quality standards suitable for cosmetic and personal care applications. We ensure identity, purity, and safety through a battery of analytical tests. A Certificate of Analysis (COA) detailing parameters such as fatty acid profile, peroxide value, acid value, and specific gravity is provided with each batch to guarantee consistency and compliance.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at temperatures between 15-25°C (59-77°F). Due to its nature of being easily oxidized, it is recommended to store under an inert atmosphere (nitrogen headspace) for long-term storage to maintain optimal freshness and prevent rancidity. Keep away from heat and open flame.
