Hardly any other cosmetic active ingredient raises as many questions at first glance as ozonated plant oils. After all, most people associate ozone with air pollution, oxidative stress, or health risks. In fact, gaseous ozone (O\u2083) in high concentrations is a strong oxidizing agent and can damage biological tissues.<\/p>\n
However, it is precisely this first impression that makes the technology so exciting.<\/p>\n
This is because, in the production of ozonated vegetable oils, gaseous ozone is not used as the actual active ingredient. Instead, it reacts in a controlled manner with the double bonds of the unsaturated fatty acids in plant oils. Once the reaction is complete, virtually no free ozone remains. Instead, stable ozonides are formed\u2014special oxygen compounds that serve as the oil\u2019s actual functional components. This fundamentally distinguishes a high-quality ozonized oil from gaseous ozone.<\/p>\n
It is precisely this controlled chemical transformation that opens up interesting possibilities for modern skincare formulations. In recent years, numerous scientific studies have been published that examine the antimicrobial properties, the support of physiological skin processes, and the influence on oxidative signaling pathways. Today, the focus is less on the direct oxidative effect and more on the ability to trigger cellular regulatory mechanisms and thereby support natural skin function.<\/p>\n
Vegetable oils consist primarily of triglycerides. The fatty acids they contain differ in terms of the number of double bonds they possess. Sunflower, soybean, and sesame oils, for example, are particularly rich in polyunsaturated fatty acids.<\/p>\n
During ozonation, ozone reacts specifically with these double bonds. This chemical process, known for decades, is called the Criegee reaction.<\/p>\n
In simplified terms, it proceeds in three steps:<\/p>\n
\u2022 Attachment of the ozone molecule to the double bond<\/p>\n
\u2022 Formation of an unstable primary ozonide<\/p>\n
\u2022 Rearrangement to form a stable secondary ozonide<\/p>\n
These stable ozonides then remain in the oil and give it its characteristic properties. The original ozone is completely converted in the process and is no longer present as a gas in the final product.<\/p>\n
Why is sunflower oil particularly suitable?<\/strong><\/p>\n Not every vegetable oil can be ozonized equally effectively.<\/p>\n The key factor is the number of unsaturated fatty acids. The more double bonds present, the more ozonides can form.<\/p>\n Among common vegetable oils, sunflower oil has a particularly high linoleic acid content and therefore possesses exceptionally high ozonization potential. This results in high concentrations of stable ozonides without the oil losing its fundamental skin compatibility.<\/p>\n Not every ozonated oil automatically has the same quality.<\/p>\n An important quality parameter is the so-called peroxide index (PI). It indirectly describes the amount of ozonides formed and thus the degree of ozonation of the oil.<\/p>\n A high peroxide index means, among other things:<\/p>\n \u2022 high concentration of stable ozonides<\/p>\n \u2022 better long-term stability<\/p>\n \u2022 lower tendency toward uncontrolled oxidation<\/p>\n \u2022 reproducible quality<\/p>\n For high-quality cosmetic raw materials, peroxide indices of several thousand mEqO\u2082\/kg are achieved today. At the same time, the peroxide index also indicates how stable the product remains during storage and formulation. Highly ozonized vegetable oils can be stored for long periods and, provided they are of sufficient quality, do not require refrigeration.<\/p>\n The real key to this technology is that the ozonides do not remain highly reactive oxidizing agents permanently.<\/p>\n Only upon contact with skin lipids and the skin\u2019s moisture do they slowly react. In the process, various reactive oxygen species (ROS) and lipid oxidation products (LOPS) are produced in controlled amounts.<\/p>\n While high levels of free radicals would be harmful, small, controlled amounts can act as biological signaling molecules. This phenomenon is also known as hormesis\u2014a stimulus is small enough not to cause damage but strong enough to activate the body\u2019s own protective mechanisms.<\/p>\n It is precisely this principle that makes high-quality ozonized vegetable oils so interesting for cosmetic applications.<\/p>\n The term \u201coxidative stress\u201d usually carries negative connotations in cosmetics. After all, free radicals are considered to be a contributing factor to skin aging, DNA damage, and inflammatory processes. However, modern research shows that this view is too simplistic.<\/p>\n Today we know that small amounts of reactive oxygen species (ROS) are important endogenous signaling molecules. Without them, numerous repair and regeneration processes could not be activated at all.<\/p>\n High-quality ozonized vegetable oils utilize precisely this principle.<\/strong><\/p>\n When ozonides come into contact with the skin, they slowly react with water and lipids on the skin\u2019s surface. This process produces controlled amounts of various oxidative signaling molecules:<\/p>\n \u2022 Reactive Oxygen Species (ROS)<\/p>\n \u2022 Lipid Oxidation Products (LOPS)<\/p>\n \u2022 Small amounts of hydrogen peroxide<\/p>\n \u2022 Other natural lipid oxidation products<\/p>\n These substances do not remain in the tissue for long but act primarily as biological messengers. They trigger a short-term activation of various cellular defense systems without maintaining chronic oxidative stress. What is crucial, therefore, is not the extent of oxidation but its controlled dosage.<\/p>\n The ROS initially formed activate the NF-\u03baB (Nuclear Factor kappa B) signaling pathway in skin cells.<\/p>\n This signaling pathway controls numerous processes that are important for physiological tissue regeneration. These include, among others:<\/p>\n \u2022 Formation of various growth factors<\/p>\n \u2022 Cell proliferation<\/p>\n \u2022 Communication between immune and skin cells<\/p>\n \u2022 Regulation of inflammatory processes<\/p>\n It is important to note that short-term activation of NF-\u03baB does not necessarily mean harmful inflammation. Rather, it is a natural component of the physiological tissue response following a controlled stimulus.<\/p>\n LOPS Activate the Body\u2019s Own Cell Protection<\/p>\n Even more interesting is the second signaling pathway.<\/p>\n While ROS have only a relatively short-lived effect, so-called lipid oxidation products (LOPS) are also formed.<\/p>\n These molecules activate the transcription factor Nrf2, which is now considered one of the body\u2019s most important regulators of antioxidant defense mechanisms.<\/p>\n Upon activation, Nrf2 migrates to the cell nucleus, where it stimulates the production of various antioxidant enzymes:<\/p>\n \u2022 Superoxide dismutase (SOD)<\/p>\n \u2022 Catalase (CAT)<\/p>\n \u2022 Glutathione peroxidase (GPX)<\/p>\n \u2022 Hem oxygenase-1 (HO-1)<\/p>\n As a result, the oxidative stimulus that was previously triggered is immediately brought back under control. The skin thus does not respond with sustained oxidation, but rather with an enhanced endogenous antioxidant response. This is precisely one of the most exciting aspects of this technology.<\/p>\n In simple terms, the mechanism can be imagined as an intelligent alarm system.<\/p>\n The initial stimulus briefly activates cellular alertness.<\/p>\n Immediately afterward, the skin initiates its own protective programs.<\/p>\n The interaction between NF-\u03baB and Nrf2 leads, among other things, to:<\/p>\n \u2022 increased production of antioxidant enzymes<\/p>\n \u2022 physiological regulation of inflammatory processes<\/p>\n \u2022 the release of various growth factors<\/p>\n \u2022 improved cellular homeostasis<\/p>\n The scientific literature describes this mechanism as a controlled biological response to a mild oxidative stimulus. The goal is not to induce oxidative stress, but to activate the body\u2019s own regulatory mechanisms.<\/p>\n Scientific studies have described the following signaling molecules, among others:<\/p>\n Growth factors<\/p>\n \u2022 Epidermal Growth Factor (EGF)<\/p>\n \u2022 Vascular Endothelial Growth Factor (VEGF)<\/p>\n \u2022 Platelet-Derived Growth Factor (PDGF)<\/p>\n \u2022 Insulin-like Growth Factor (IGF)<\/p>\n \u2022 Transforming Growth Factor \u03b2 (TGF-\u03b2)<\/p>\n Antioxidant enzymes<\/p>\n \u2022 Superoxide dismutase<\/p>\n \u2022 Catalase<\/p>\n \u2022 Glutathione peroxidase<\/p>\n Immunoregulatory cytokines<\/p>\n \u2022 IL-1<\/p>\n \u2022 IL-6<\/p>\n \u2022 IL-8<\/p>\n \u2022 IL-10<\/p>\n \u2022 TNF<\/p>\n \u2022 Interferons<\/p>\n These are the body\u2019s own signaling molecules, the production of which is described as part of the physiological cellular response. However, this should not automatically lead to claims of cosmetic efficacy or medical healing promises.<\/p>\n Many formulators ask themselves this question when they first encounter ozonized plant oils.<\/p>\n The key difference is that it is not gaseous ozone that comes into contact with the skin.<\/p>\n The ozone has already been completely chemically converted during the manufacturing process. The final product consists primarily of stable ozonides, which release their stored energy only gradually.<\/p>\n To put it simply:<\/strong><\/p>\n Gaseous ozone acts as a very aggressive oxidizing agent in the short term.<\/p>\n Ozonated vegetable oils, on the other hand, function more like a slow-acting biological signaling system.<\/p>\n It is precisely this controlled release that makes high-quality ozonated vegetable oils interesting for cosmetic applications and explains why, despite their initially unusual name, they are gaining increasing attention in modern skincare concepts.<\/p>\n Advantages and Disadvantages of Ozonized Vegetable Oils in Cosmetics<\/p>\n Like any innovative active ingredient technology, ozonized vegetable oils have clear strengths but also limitations that formulators should be aware of. When used correctly, they can meaningfully expand the active ingredient portfolio of modern skincare.<\/p>\n 1. Multifunctional Mode of Action<\/strong><\/p>\n While many cosmetic active ingredients address only a single biological effect, ozonized plant oils combine several modes of action simultaneously. The controlled formation of ROS and LOPS can activate physiological signaling pathways, while the underlying plant oil simultaneously nourishes the skin barrier. As a result, they combine skincare properties with an interesting biological mechanism of action.<\/p>\n 2. Support for the skin\u2019s natural balance<\/strong><\/p>\n Rather than acting solely as antioxidants, high-quality ozonized vegetable oils stimulate the body\u2019s own antioxidant defense mechanisms. This supports the skin\u2019s natural homeostasis\u2014an approach that differs significantly from that of traditional antioxidants.<\/p>\n 3. Beneficial for Blemished Skin<\/strong><\/p>\n The scientific literature describes the antimicrobial properties of high-quality ozonized oils against various microorganisms. For cosmetic applications, this opens up potential for products designed for blemished skin or skin prone to blemishes. Of course, only cosmetically permissible claims may be used in this context.<\/p>\n 4. Good Formulability<\/b><\/p>\n Ozonized vegetable oils can be integrated into numerous galenic systems:<\/p>\n \u2022 O\/W emulsions<\/p>\n \u2022 W\/O emulsions<\/p>\n \u2022 Oleogels<\/p>\n \u2022 Hydrogels<\/p>\n \u2022 Balms<\/p>\n \u2022 Ointment-like formulations<\/p>\n \u2022 Massage oils<\/p>\n \u2022 Anhydrous skincare products<\/p>\n This makes them suitable for both traditional skincare and specialized skincare regimens.<\/p>\n 5. High Stability of High-Quality Formulations<\/strong><\/p>\n A sufficiently high peroxide index ensures significantly better storage stability than is often assumed. Modern manufacturing processes achieve stable ozonide structures that remain intact even over extended storage periods.<\/p>\n An objective assessment is also part of a technical article.<\/p>\n Characteristic Odor<\/strong><\/p>\n Probably the biggest disadvantage is the typical ozone-like or slightly pungent odor. This can vary in intensity depending on the degree of ozonization and often must be addressed through appropriate fragrance addition or a skillful formulation strategy. This certain degree of natural rancidity must be accepted.<\/p>\n Higher Raw Material Costs<\/strong><\/p>\n The production of high-quality ozonized vegetable oils is technically demanding and time-consuming. Accordingly, raw material prices are usually significantly higher than those of conventional vegetable oils.<\/p>\n Not a \u201cMiracle Cure\u201d<\/strong><\/p>\n Although numerous scientific studies describe interesting biological mechanisms, these remain cosmetic raw materials. Claims regarding the treatment or cure of diseases are, of course, not permitted in cosmetic products.<\/p>\n Formulation Expertise Required<\/strong><\/p>\n A high peroxide value alone does not guarantee a good final product. Emulsifier systems, antioxidants, packaging, and pH level should be carefully balanced to achieve optimal stability and sensory quality.<\/p>\n Due to their unique mechanism of action, ozonized vegetable oils are particularly well-suited for innovative skincare concepts.<\/p>\n Possible product ideas include, for example:<\/strong><\/p>\n Barrier Repair Serum<\/strong><\/p>\n A lightweight night serum to support a stressed skin barrier, combined with ceramides, ectoine, and panthenol.<\/p>\n Calming Repair Cream<\/strong><\/p>\n A soothing face cream for sensitive skin with beta-glucan, oat extract, bisabolol, and ozonized sunflower oil.<\/p>\n SOS Skin Balm<\/strong><\/p>\n A water-free skin balm for particularly stressed areas of the skin on the hands, elbows, or feet.<\/p>\n After-Sun Recovery Gel-Cream<\/strong><\/p>\n Combines ozonized plant oils with ectoine, aloe vera, betaine, and low-molecular-weight hyaluronic acid to care for sun-stressed skin.<\/p>\n Purifying Face Oil<\/strong><\/p>\n A modern facial oil for blemish-prone or oily skin, formulated with squalane, jojoba oil, and bakuchiol.<\/p>\n Lip Repair Balm<\/strong><\/p>\n A regenerating lip balm with shea butter, phytosterols, and ozonized sunflower oil for dry and stressed lips.<\/p>\n The term \u201cozone\u201d often initially triggers skepticism. Upon closer examination, however, it becomes clear that high-quality ozonized plant oils have nothing in common with the direct application of gaseous ozone.<\/p>\n The controlled reaction of ozone with unsaturated vegetable oils produces stable ozonides that can trigger controlled biological signaling processes upon contact with the skin. The activation of the NF-\u03baB and Nrf2 signaling pathways, as well as the subsequent stimulation of antioxidant defense mechanisms, make this technology an exciting approach for modern cosmetic formulations.<\/p>\n Of particular interest is the paradigm shift: rather than solely combating free radicals, this technology uses a mild oxidative stimulus to activate the skin\u2019s own protective and regulatory mechanisms. This hormetic approach is also gaining increasing importance in other areas of dermatology and cosmetics.<\/p>\n High-quality ozonized vegetable oils therefore offer an interesting addition to innovative skincare concepts\u2014provided they are used in suitable formulations and their potential and limitations are evaluated on a scientifically sound basis.<\/p>\n Developing modern cosmetic products requires far more than simply selecting an interesting active ingredient. Only the optimal combination of active ingredient technology, galenics, stability, sensory properties, and regulatory compliance determines future market success.<\/p>\n Cosmacon supports you from the initial product idea through to a market-ready formulation.
