Ingredient review
Chloroxylenol
INCI: Chloroxylenol
Chloroxylenol is an effective preservative that helps keep products safe from bacteria and fungi, but it can be irritating for some people, especially at higher concentrations.
In plain English
Chloroxylenol is a man-made chemical added to skincare products to stop germs like bacteria and mold from growing. Think of it as a tiny guard that keeps your lotion or cleanser from spoiling. It's often used in soaps and washes because it's good at killing microbes on the skin, but it can sometimes cause redness or stinging, especially if you have sensitive skin.

Quick decision guide
Useful, but context matters
Chloroxylenol 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 Chloroxylenol.
- 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
strongThere is a stronger practical or research basis for the ingredient role described here.
What it is
Chloroxylenol is a halogenated phenolic compound that acts as a preservative and antiseptic. It is a white crystalline solid that is poorly soluble in water but dissolves well in alcohols and oils, making it suitable for a variety of cosmetic formulations.
How it works
Chloroxylenol works by disrupting the cell walls and membranes of microorganisms like bacteria and fungi. It interferes with their ability to function and reproduce, effectively killing them or stopping their growth. In a product, this keeps the formula stable and safe to use over time.
Pros
Effective germ fighter
Chloroxylenol is proven to kill a wide range of bacteria, yeast, and mold, which helps keep your products safe from contamination and spoilage.
Low use level
Because it works at small concentrations (often under 0.5%), it doesn't need to dominate a formula, leaving room for other beneficial ingredients.
Cons and cautions
Can irritate sensitive skin
For some people, especially those with eczema or very reactive skin, chloroxylenol may cause redness, itching, or a stinging sensation, particularly in leave-on products.
May affect skin microbiome
As a broad-spectrum antimicrobial, it doesn't distinguish between harmful and beneficial bacteria, so frequent use could disrupt the natural balance of your skin's microbiome.
Best for
- People who use water-based products that need a preservative to stay fresh
- Those looking for a well-studied, effective preservative in cleansers and wash-off products
Use caution if
- Individuals with very sensitive, reactive, or eczema-prone skin, especially in leave-on products
Usage tips
Safety summary
Chloroxylenol is considered safe for use in cosmetics at concentrations up to 0.5% based on regulatory assessments. However, it can cause skin irritation and allergic reactions in some individuals, particularly those with sensitive skin or when used in leave-on products. It is not recommended for use on broken skin or mucous membranes.
Research notes
Chloroxylenol has been extensively studied as an antimicrobial agent. Research supports its effectiveness against a broad range of microorganisms, and safety assessments by bodies like the Cosmetic Ingredient Review (CIR) have concluded it is safe at low concentrations. Some studies note potential for skin sensitization and irritation at higher levels.
Common label clues
- Typical concentration
- 0.1% to 0.5%
- Regulatory status
- Chloroxylenol is regulated as a cosmetic preservative in many regions. In the EU, it is listed in Annex V of the Cosmetics Regulation with a maximum authorized concentration of 0.5%. In the US, it is generally recognized as safe when used as a preservative within recommended limits.
- Common uses
- Cleansers, Body washes, Bar soaps, Antiseptic creams, Wipes
- Environmental note
- Chloroxylenol is synthetic and not readily biodegradable. It can accumulate in waterways, so its environmental impact is a consideration for manufacturers aiming for eco-friendly formulations.
Good to know
- Chloroxylenol is the active ingredient in some over-the-counter antiseptic solutions like Dettol, but in skincare it is used at much lower levels.
- It is approved for use in cosmetics in many countries, including the EU and the US, with concentration limits to ensure safety.
