Ingredient review
TEA-Dodecylbenzenesulfonate
INCI: TEA-Dodecylbenzenesulfonate
An effective but potentially drying surfactant best suited for rinse-off cleansers, not for sensitive or dry skin.
In plain English
TEA-Dodecylbenzenesulfonate is a synthetic detergent that helps water mix with oil and dirt so they can be rinsed away. It creates a rich lather and is commonly found in shampoos, body washes, and facial cleansers. However, because it can strip the skin of its natural oils, it may cause dryness or irritation, especially for those with sensitive or dry skin.

TEA-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 TEA-Dodecylbenzenesulfonate.
- Step 2Use the "Best for" and "Use caution if" sections to match the ingredient to your skin, not just to a marketing claim.

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 dodecylbenzene sulfonic acid neutralized with triethanolamine. It is a strong cleansing agent that produces abundant foam.
How it works
It reduces the surface tension between water and oil, allowing oils and dirt to be emulsified and washed away. Its negatively charged head group binds to positively charged particles, enhancing removal of debris and sebum.
Pros
Strong cleanser
Effectively removes excess oil, makeup, and impurities, leaving skin feeling thoroughly clean.
Good foam
Produces a rich, creamy lather that many people associate with a satisfying cleansing experience.
Cons and cautions
Can be drying
May strip the skin's natural moisture barrier, leading to tightness, flakiness, or irritation with frequent use.
Irritation potential
Moderate risk of causing redness or stinging, especially on sensitive or already irritated skin.
Best for
- People with oily or combination skin who want a deep cleanse
- Those who prefer a foaming, lathering cleanser
Use caution if
- Individuals with dry, sensitive, or eczema-prone skin
- Anyone seeking a gentle, non-stripping cleanser
Usage tips
Safety summary
Generally safe for occasional use in rinse-off products, but can cause dryness and irritation with frequent or prolonged contact. Avoid contact with eyes and broken skin.
Research notes
Studies confirm its effectiveness as a surfactant but also note its potential to disrupt the skin barrier and cause irritation at higher concentrations. Safer alternatives exist for sensitive skin.
Common label clues
