Ingredient review
Sodium Dodecylbenzenesulfonate
INCI: SODIUM DODECYLBENZENESULFONATE
A strong synthetic cleanser that effectively removes dirt and oil but can be drying or irritating for sensitive skin.
In plain English
Sodium dodecylbenzenesulfonate is a man-made ingredient that helps products foam up and wash away oil and dirt. It's similar to sodium lauryl sulfate (SLS) but slightly milder. Because it can strip the skin's natural oils, it may cause dryness or irritation, especially for people with sensitive or dry skin. It's most often found in shampoos, body washes, and facial cleansers that you rinse off quickly.

Quick decision guide
Read the cautions before using
Sodium Dodecylbenzenesulfonate 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 Sodium Dodecylbenzenesulfonate.
- 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
A synthetic anionic surfactant derived from petroleum, commonly used in personal care and household cleaning products for its strong cleansing and foaming properties.
How it works
It works by reducing the surface tension between water and oil, allowing water to mix with oils and dirt so they can be rinsed away. This creates a rich lather that helps physically remove impurities from the skin and hair.
Pros
Strong cleanser
Effectively removes excess oil, dirt, and makeup, making it useful for oily skin types or heavy-duty cleansing.
Good foam
Produces a rich, bubbly lather that many people associate with a satisfying cleansing experience.
Cons and cautions
Can be drying
Strips natural oils from the skin and hair, which can lead to dryness, tightness, and irritation over time.
Potential irritant
May cause redness, stinging, or allergic reactions, especially for those with sensitive skin or conditions like rosacea.
Best for
- People with oily or normal skin who prefer a strong, foaming cleanser
- Those using rinse-off products like shampoo or body wash
Use caution if
- Individuals with dry, sensitive, or eczema-prone skin
- Anyone looking for a gentle, sulfate-free cleansing option
Usage tips
Safety summary
Generally considered safe for use in rinse-off products at typical concentrations, but can cause skin and eye irritation, especially with prolonged contact or in sensitive individuals. Avoid in leave-on formulations.
Research notes
Studies show that sodium dodecylbenzenesulfonate is an effective surfactant but can disrupt the skin barrier and cause irritation at higher concentrations. It is less studied than SLS but shares similar safety concerns.
Common label clues
- Typical concentration
- 1–10% in rinse-off products; lower in leave-on formulations
- Regulatory status
- Approved for use in cosmetics in the US (FDA) and EU (CosIng) at concentrations typically up to 10% in rinse-off products. Not restricted but subject to general safety requirements.
- Common uses
- Shampoos, Body washes, Facial cleansers, Household detergents
- Environmental note
- This ingredient is not readily biodegradable in all environments and may accumulate in water systems. Some manufacturers are moving toward more eco-friendly alternatives.
Good to know
- Sodium dodecylbenzenesulfonate is often used in combination with milder surfactants to reduce irritation.
- It is not the same as sodium lauryl sulfate (SLS), but they are chemically similar and share many properties.
