Ingredient review
Ozonized Polysorbate 80
INCI: OZONIZED POLYSORBATE 80
Ozonized Polysorbate 80 is a modified emulsifier with potential antimicrobial benefits, but its ozone content may cause irritation for sensitive skin.
In plain English
Ozonized Polysorbate 80 is a special version of a common skincare ingredient (Polysorbate 80) that has been infused with ozone gas. This process is thought to give it extra cleansing and bacteria-fighting abilities. In simple terms, it helps mix water and oil in a product while also aiming to keep the skin clean. However, because it contains ozone, it can be a bit harsh for some people, especially those with sensitive or dry skin.

Quick decision guide
Useful, but context matters
Ozonized Polysorbate 80 can be useful, but watch for some irritation potential.
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 Polysorbate 80.
- 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
moderateCan bother some users, especially with frequent use, damaged skin, or strong companion ingredients.
Clogging risk
lowLess likely to feel heavy or contribute to clogged pores for most skin types.
Evidence level
emergingThe ingredient may be promising, but claims should be treated more cautiously.
What it is
Ozonized Polysorbate 80 is a semi-synthetic compound created by reacting Polysorbate 80 (a common emulsifier derived from sorbitol and oleic acid) with ozone. The ozone treatment introduces oxygen-rich groups into the molecule, which may enhance its antimicrobial and cleansing properties.
How it works
In a cosmetic product, Ozonized Polysorbate 80 acts as a surfactant and emulsifier, helping to blend oil and water so the product has a smooth texture. The ozone component may also disrupt the cell walls of certain bacteria and fungi, potentially reducing microbial growth on the skin. This makes it useful in cleansers designed for acne-prone skin.
Pros
Enhanced cleansing
The ozone treatment may boost the ingredient's ability to remove excess oil and impurities, making it effective for oily skin types.
Potential antimicrobial action
Ozone is known for its germ-killing properties, which could help reduce acne-causing bacteria on the skin's surface.
Cons and cautions
Irritation risk
Ozone can be a strong oxidizer, and this ingredient may cause stinging, redness, or dryness, particularly for those with sensitive skin.
Limited evidence
There is very little published research on Ozonized Polysorbate 80 specifically in skincare, so its benefits and safety are not well-established.
Best for
- People with oily or acne-prone skin looking for a deep cleanser
- Those who tolerate mild surfactants and want extra cleansing power
Use caution if
- Individuals with sensitive, dry, or compromised skin barriers
- Anyone with known allergies to polysorbates or ozone-treated ingredients
Usage tips
Safety summary
Ozonized Polysorbate 80 is generally considered safe for use in rinse-off cosmetics at low concentrations, but it carries a moderate risk of irritation due to its ozone content. People with sensitive skin should approach with caution. Long-term safety data is lacking.
Research notes
Research on Ozonized Polysorbate 80 in cosmetics is minimal. Most knowledge comes from studies on ozonated oils and general polysorbate safety. The antimicrobial potential is plausible but not well-documented for this specific ingredient.
Common label clues
- Typical concentration
- Typically 0.5% to 5% in rinse-off products
- Regulatory status
- Not specifically regulated as a separate ingredient by the FDA or EU CosIng; Polysorbate 80 is widely approved, but ozonized versions are less common and may require safety assessment by the manufacturer.
- Common uses
- Cleansers, Facial washes, Acne treatments
- Environmental note
- Polysorbate 80 is biodegradable, but the ozonization process may introduce additional chemical modifications that could affect environmental fate. Limited data available.
Good to know
- Ozonized Polysorbate 80 is not the same as regular Polysorbate 80; the ozone treatment changes its properties
- It may have a slight ozone smell, which is normal and fades quickly
