Science
Mechanism of Action
This oil fortifies the skin's natural barrier and reduces transdermal water loss through its rich profile of monounsaturated fatty acids, with oleic acid comprising 50-67% and palmitoleic acid 12-25%. Palmitoleic acid actively supports cellular regeneration, which aids in mitigating the appearance of fine lines and wrinkles. Furthermore, the oil delivers robust antioxidant defense against free radicals and oxidative stress, attributed to its content of vitamin E, squalene, and phenolic compounds. Its inherent anti-inflammatory properties contribute to soothing irritation, redness, and inflammation across various skin conditions.

Key findings
- 01 In human volunteers, both nanoemulsions and conventional emulsions containing 15% w/w macadamia integrifolia oil significantly enhanced skin hydration and reduced skin wrinkles, with nanoemulsions demonstrating superior hydration. The oil also exhibited potent activity as an ABTS•+ radical scavenger, lipid peroxidation inhibitor, and hyaluronidase inhibitor.

Stability
Macadamia Integrifolia Seed Oil generally possesses good oxidative stability. However, prolonged exposure to air can gradually lead to oxidation and the liberation of free fatty acids, potentially resulting in rancidity. Optimal storage involves a tightly closed original container, in a cool (maximum room temperature), dry, and ventilated area, shielded from heat sources and ignition.

Safety
Safety Profile
The Cosmetic Ingredient Review (CIR) Expert Panel has concluded that Macadamia Integrifolia Seed Oil is safe for use in cosmetic and personal care products. While generally well-tolerated and non-irritating, individuals with known macadamia nut allergies are advised to conduct patch testing. Regulatory advisories, such as the FDA's Food Allergen Labeling and Consumer Protection Act, primarily address macadamia nut allergenicity in food products.
