Science
Mechanism of Action
Upon topical application, Ozonized Oleic Acid interacts with biological fluids, polyunsaturated fatty acids, and water in the dermis. This reaction generates reactive oxygen species (ROS), including H2O2, and lipo-oligopeptides, which are partially modulated by the skin's enzymatic and non-enzymatic antioxidants. It acts as a bio-regulator, influencing cellular redox balance and potentially altering cytokine levels such as interleukin-8 and TNF-α. The stable ozonides and lipoperoxides deliver active oxygen, inducing a moderate, transient oxidative stress that stimulates the body's natural antioxidant production, triggering tissue repair and regeneration. Additionally, its oxidizing properties disrupt bacterial cell walls, enhancing permeability and exhibiting germicidal effects.

Stability
Ozonized oleic acid, as part of ozonated oils, typically remains stable for 2-3 years when stored at 4°C, with stability influenced by the stabilization method. Refrigeration and careful handling enhance its shelf life significantly. Ozonide structures within nanoemulsions have shown stability for at least 30 days at room temperature. Rigorous quality control is essential, particularly monitoring the peroxide value (PV) for accurate dosage, and ensuring the absence of formaldehyde and controlled levels of acid number and malondialdehyde to prevent potential irritation and hypersensitivity. High viscosity and an unpleasant odor are common formulation challenges.
Conflicts
- Unsaturated compounds (ozone readily reacts with carbon-carbon double bonds in unsaturated fatty acids, forming ozonides and peroxides).
Safety
Safety Profile
While Oleic Acid, the base fatty acid, has been deemed safe by the CIR Expert Panel up to 13% in cosmetics (provided it's non-irritating/non-sensitizing), Ozonized Oleic Acid itself has not been specifically reviewed by CIR or SCCS. Preliminary evidence suggests ozonated liquids are generally well tolerated with no significant dermatological risks, and no cytotoxic effects have been observed at concentrations up to 4 ppm on human skin cells. However, mild adverse effects such as desquamation and transient burning sensations have been reported in some clinical studies. To mitigate the risk of hypersensitivity reactions or irritation, stringent quality control is paramount, particularly ensuring the absence of formaldehyde and maintaining controlled levels of acid number and malondialdehyde. Ozonated olive oil and ozonated sunflower oil are registered under Europe's REACH regulation, indicating regulatory acceptance for related ozonated lipids.
