Ingredient review
Chlorophene
INCI: CHLOROPHENE
Chlorophene is an effective preservative but may cause skin irritation in sensitive individuals, especially at higher concentrations.
In plain English
Chlorophene is a man-made chemical added to products like cleansers and hand sanitizers to stop bacteria, yeast, and mold from growing. It helps keep the product safe to use over time. However, it can be a bit harsh for very sensitive or irritated skin, so it's more common in rinse-off products than in lotions you leave on your face.

Quick decision guide
Useful, but context matters
Chlorophene 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 Chlorophene.
- 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
moderateThere is useful support, but formula details and claim strength still matter.
What it is
Chlorophene is a synthetic organic compound belonging to the class of chlorinated phenols. It is used as a broad-spectrum antimicrobial preservative in cosmetics and personal care products.
How it works
Chlorophene disrupts the cell membranes of microorganisms, causing them to break down and die. This prevents bacterial, fungal, and yeast growth in the product, extending its shelf life and ensuring safety during use.
Pros
Strong preservative power
Chlorophene effectively prevents microbial growth, keeping products safe and stable for longer periods.
Works in rinse-off products
It is particularly effective in cleansers and soaps where brief contact minimizes irritation risk while still providing protection.
Cons and cautions
Can irritate sensitive skin
At higher concentrations or in leave-on products, chlorophene may cause redness, stinging, or contact dermatitis in some people.
Environmental concerns
As a chlorinated compound, chlorophene may persist in water systems and raise ecological questions, though it is approved for cosmetic use.
Best for
- People using rinse-off products like body washes or hand soaps
- Those who prefer products with synthetic preservatives for reliable antimicrobial protection
Use caution if
- Individuals with very sensitive, reactive, or eczema-prone skin
Usage tips
Safety summary
Chlorophene is considered safe for use in cosmetics at regulated concentrations, but it can cause skin irritation in sensitive individuals. It is not recommended for leave-on products on compromised skin. Overall, it is a reliable preservative with moderate irritation potential.
Research notes
Studies confirm chlorophene's broad-spectrum antimicrobial efficacy. Human patch tests show low to moderate irritation potential, with higher risk at concentrations above 0.5%. Environmental persistence is noted in some aquatic studies, but cosmetic use levels are considered safe by regulatory bodies.
Common label clues
- Typical concentration
- Up to 0.5% in rinse-off products; lower in leave-on formulations
- Regulatory status
- Approved for use in cosmetics in the EU, US, and many other regions, typically at concentrations up to 0.5% in rinse-off products. Always follow local regulations.
- Common uses
- Cleansers, Soaps, Hand sanitizers, Leave-on products
- Environmental note
- Chlorophene is a chlorinated compound that may be slow to biodegrade. Its use in rinse-off products means it can enter wastewater, so some regions monitor its environmental impact.
Good to know
- Chlorophene is sometimes listed under the INCI name CHLOROPHENE or as o-Benzyl-p-chlorophenol.
- It is not the same as triclosan, though both are synthetic antimicrobials.
