Ingredient review
Ozonized PEG-14 Oleate
INCI: OZONIZED PEG-14 OLEATE
A mild emulsifier that helps blend oil and water in cleansers, with added ozonized fatty acids for potential skin-soothing benefits.
In plain English
Ozonized PEG-14 Oleate is a gentle ingredient used in cleansers and shampoos to help mix oil and water so they rinse away easily. The 'ozonized' part means the fatty acids have been treated with ozone, which may give them mild soothing properties. It's not a star ingredient but a reliable helper that makes products feel less stripping.

Quick decision guide
Useful, but context matters
Ozonized PEG-14 Oleate is generally a lower-concern ingredient when the full formula suits your skin.
Plain-English read
Treat this as a practical screening step before you compare products that contain this ingredient.
- Step 1Start with the score, then check the irritation and clogging risk before judging Ozonized PEG-14 Oleate.
- Step 2Use the "Best for" and "Use caution if" sections to match the ingredient to your skin, not just to a marketing claim.
- Step 3If a product stings, breaks you out, or worsens irritation, judge the finished formula and stop using it even if the ingredient scores well.
Score terms in plain English
Irritation risk
lowLess likely to sting, burn, or bother most users, though sensitive skin can still react.
Clogging risk
lowLess likely to feel heavy or contribute to clogged pores for most skin types.
Evidence level
moderateThere is useful support, but formula details and claim strength still matter.
What it is
A semi-synthetic compound made by reacting oleic acid (a fatty acid from oils) with ethylene oxide (PEG) and then treating it with ozone. It acts as an emulsifier and mild surfactant.
How it works
It reduces the surface tension between oil and water, allowing them to blend into a stable lotion or cream. In cleansers, it helps lift dirt and oil from the skin so they can be rinsed away without harshness.
Pros
Gentle cleanser
It cleans without stripping the skin's natural moisture barrier, making it suitable for daily use.
Stable emulsions
It helps create smooth, stable lotions and creams that don't separate, improving product texture.
Cons and cautions
Potential impurities
PEG compounds can contain trace impurities like ethylene oxide if not properly purified, though reputable brands ensure safety.
Limited research
There is less published research on ozonized PEG-14 Oleate compared to more common emulsifiers, so its unique benefits are not fully proven.
Best for
- People with normal to oily skin looking for a gentle cleanser
- Anyone who prefers mild surfactants in rinse-off products
Use caution if
- Those with known sensitivity to PEG compounds (rare)
- People seeking completely natural formulations
Usage tips
Safety summary
Ozonized PEG-14 Oleate is considered safe for use in cosmetics at typical concentrations. The main concern is potential contamination with ethylene oxide, but modern manufacturing controls keep this risk very low. It is non-irritating and non-comedogenic for most people.
Research notes
Research on PEG-14 Oleate specifically is limited, but PEG-based emulsifiers are well-studied and widely used. Ozonization of fatty acids has been explored for antimicrobial and wound-healing properties, though more studies are needed in cosmetic contexts.
Common label clues
- Typical concentration
- Typically 1–5% in rinse-off products
- Regulatory status
- Approved for use in cosmetics in the EU, US, and other major markets, subject to purity standards for PEG compounds.
- Common uses
- Cleansers, Shampoos, Body washes, Makeup removers
- Environmental note
- PEG compounds are generally biodegradable, but their production involves petrochemicals. Ozonization adds an extra processing step.
Good to know
- Ozonization is a process that adds oxygen to fatty acids, which may give them mild antimicrobial or soothing properties
- This ingredient is often used in products labeled as 'gentle' or 'soothing'
