What Is Ozonized Peg-14 Oleate?
Ozonized Peg-14 Oleate is a specialty ingredient created by bubbling ozone through PEG-14 oleate, a compound derived from oleic acid (a fatty acid found in plant oils) that has been linked with polyethylene glycol units for better water compatibility. The controlled exposure to ozone alters the original molecule, giving it mild oxidative properties that can fight unwanted microbes while keeping the surfactant qualities of the base material.
Formulators first explored ozone-treated oils in the 1990s for their ability to keep products fresh without heavy preservatives. Over time, the method was refined to target PEG-linked fatty acids like PEG-14 oleate because these molecules disperse easily in water-based formulas, making them convenient for skin care and hair care labs.
Manufacturing starts with high-purity PEG-14 oleate. Ozone is passed through the liquid under controlled temperature and time until lab tests confirm the desired peroxide value. Any excess ozone is removed, and the finished ingredient is filtered and stabilized before shipment.
You will spot Ozonized Peg-14 Oleate in lightweight facial cleansers, micellar waters, clay or sheet masks, leave-on acne treatments, refreshing body washes, and some scalp-care lotions where formulators want a gentle cleansing agent with built-in antimicrobial support.
Ozonized Peg-14 Oleate’s Cosmetic Benefits/Uses
Here is what this multitasking ingredient brings to a formula
- Antimicrobial: Helps limit the growth of bacteria and fungi in the product and on the skin surface which can improve shelf life and support clearer skin
- Cleansing: Acts as a mild surfactant that lifts away excess oil dirt and makeup without stripping the skin’s natural barrier
Who Can Use Ozonized Peg-14 Oleate
Ozonized Peg-14 Oleate is generally well tolerated by most skin types, including oily, combination, dry and sensitive skin, thanks to its mild cleansing profile and low likelihood of clogging pores. Very sensitive or eczema-prone skin may still prefer a patch-free formula with fewer actives, so checking overall product composition matters.
The ingredient is synthetic and sourced from plant-derived oleic acid plus lab-made polyethylene glycol units, making it suitable for vegans and vegetarians. No animal-based raw materials or by-products are used during manufacturing.
Current data shows no specific risks for pregnant or breastfeeding women when the ingredient is used topically at the low levels found in finished cosmetics. That said, this is not medical advice and anyone who is pregnant or nursing should run new skincare products past a healthcare professional to be on the safe side.
Ozonized Peg-14 Oleate does not increase photosensitivity, so there is no extra sun-related caution beyond the daily recommendation to use broad-spectrum sunscreen.
Potential Side Effects/Adverse Reactions
Reactions to topical Ozonized Peg-14 Oleate vary from person to person. The issues listed below are potential side effects and are highly unlikely to be the typical user experience. When the ingredient is properly incorporated by a reputable manufacturer most users will not encounter problems.
- Mild skin irritation: Rare stinging or redness can occur, usually in very sensitive skin or when the formula contains other strong actives
- Contact dermatitis: An uncommon allergic reaction presenting as itching or rash
- Eye irritation: Possible if the product accidentally gets into the eyes, more relevant for cleansers and masks
- Dryness or tightness: Unlikely but may appear if the overall formula is stripped of emollients or if overused
If any negative reaction develops discontinue use and consult a qualified healthcare provider or dermatologist.
Comedogenic Rating
Rating: 1/5
Although the base molecule comes from oleic acid, the PEG-14 link makes it highly water compatible, so it rinses off cleanly and is unlikely to build up inside pores. The mild oxidative changes from ozonation also keep the texture lighter than regular oils. All of this means the ingredient has a very low chance of clogging pores.
Suitable for acne-prone and breakout-prone skin in most cases. Only those who react to any fatty acid derivative might want to keep an eye on how their skin responds over time.
Summary
Ozonized Peg-14 Oleate works as a gentle cleanser and built-in antimicrobial. Its PEG chain lets it mix with water to lift away oil dirt and makeup while the ozone-derived peroxides curb microbes that can spoil a product or upset skin. You will mainly find it in modern lightweight cleansers micellar waters and a few targeted treatments, but it is still a niche ingredient that has not hit mainstream status yet.
Current safety data shows it is low risk for irritation and has no known long-term hazards when used at normal cosmetic levels. As with any new skincare ingredient it is smart to patch test first and watch how your skin responds.
