Ingredient review
Dodoxynol-13
INCI: Dodoxynol-13
Dodoxynol-13 is a synthetic cleansing agent that helps remove dirt and oil, but may be slightly drying or irritating for sensitive skin.
In plain English
Dodoxynol-13 is a man-made ingredient that helps cleansers foam up and lift away oil and dirt from your skin. It belongs to a group of ingredients called surfactants, which work like a bridge between water and oil so that both can be rinsed away together. While effective at cleaning, it can sometimes strip the skin of its natural moisture barrier, especially if used in high amounts or on already dry or sensitive skin.

Dodoxynol-13 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 Dodoxynol-13.
- 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
Dodoxynol-13 is a synthetic nonionic surfactant derived from dodecyl alcohol and ethylene oxide. It is used primarily in rinse-off cleansing products to improve foaming and emulsification.
How it works
In a cosmetic product, Dodoxynol-13 reduces the surface tension between water and oil, allowing them to mix. This helps the product spread easily, lift sebum and makeup from the skin, and rinse away cleanly without leaving a greasy residue.
Pros
Strong cleanser
Effectively removes excess oil, makeup, and daily grime, leaving skin feeling fresh.
Good foam
Creates a satisfying lather that many people associate with a deep clean.
Cons and cautions
Potential dryness
Can strip the skin's natural oils, leading to tightness or flakiness, especially in cold or dry climates.
Irritation risk
May cause stinging or redness for those with eczema, rosacea, or other skin sensitivities.
Best for
- People with normal to oily skin looking for a thorough cleanse
- Those who prefer foaming cleansers and do not have sensitive skin
Use caution if
- Individuals with dry, compromised, or very sensitive skin
Usage tips
Safety summary
Dodoxynol-13 is considered safe for use in rinse-off cosmetics at typical concentrations. However, it may cause mild to moderate irritation in sensitive individuals, especially with frequent use. It is not known to be comedogenic.
Research notes
Limited peer-reviewed studies specifically on Dodoxynol-13 exist. Its safety profile is inferred from the broader class of ethoxylated alcohols, which are generally recognized as safe by cosmetic ingredient review panels when used as directed.
Common label clues
- Typical concentration
- Typically 0.5% to 5% in rinse-off products
- Regulatory status
- Approved for use in cosmetics in the US, EU, and many other regions. No specific restrictions beyond general surfactant safety limits.
- Common uses
- Cleansers, Shampoos, Body washes, Facial washes
- Environmental note
- As a synthetic surfactant, its biodegradability varies. Some ethoxylated surfactants can persist in the environment, but Dodoxynol-13 is generally considered to have moderate biodegradability.
Good to know
- Dodoxynol-13 is often found in combination with milder surfactants to reduce irritation.
- It is not typically used in leave-on products like lotions or serums.
