MIPA-Dodecylbenzenesulfonate
INCI: MIPA-Dodecylbenzenesulfonate
An effective but potentially drying surfactant that may irritate sensitive skin; best for normal to oily skin types in rinse-off formulas.
In plain English
MIPA-Dodecylbenzenesulfonate is a synthetic ingredient 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 and body washes. Because it can strip natural oils, it may leave skin feeling tight or dry, especially if you have sensitive or dry skin.

Quick decision guide
Useful, but context matters
MIPA-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 MIPA-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

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 monoisopropanolamine (MIPA). It belongs to the alkylbenzene sulfonate family, widely used in industrial and personal care cleaning products.
How it works
It reduces the surface tension between water and oil, allowing oils, dirt, and sebum to be emulsified and washed away. Its negatively charged head group attracts water, while the long hydrocarbon tail binds to oils, making it an effective cleanser.
Pros
Strong cleansing power
Effectively removes excess sebum, dirt, and product buildup, making it suitable for oily skin types.
Good foam quality
Produces a rich, stable lather that many users associate with a satisfying clean feeling.
Cons and cautions
Potential for dryness
Can strip the skin's natural moisture barrier, leading to tightness, flakiness, or irritation with frequent use.
Moderate irritation risk
May cause stinging or redness on sensitive or compromised skin, especially in high concentrations.
Best for
- People with normal to oily skin
- Those who prefer a foaming cleanser for body or hair
Use caution if
- Individuals with dry, sensitive, or eczema-prone skin
- Anyone looking for a sulfate-free or gentle cleansing routine
Usage tips
Safety summary
Generally recognized as safe for rinse-off use at typical concentrations, but it can be irritating to sensitive skin and may cause dryness with overuse. Avoid contact with eyes.
Research notes
Studies confirm its efficacy as a surfactant and foaming agent. Irritation potential is dose-dependent and higher in leave-on applications. No significant systemic toxicity is reported from topical use.
Common label clues
- Typical concentration
- 1–15% in rinse-off products
- Regulatory status
- Approved for use in cosmetics in the EU, US, and many other regions. Concentration limits may apply in rinse-off products to minimize irritation.
- Common uses
- Shampoos, Body washes, Facial cleansers, Hand soaps
- Environmental note
- Alkylbenzene sulfonates can be slow to biodegrade in some environments; look for formulations with biodegradable surfactants if this is a concern.
Good to know
- MIPA-Dodecylbenzenesulfonate is not the same as SLS or SLES, but it shares similar cleansing and foaming properties.
- It is often used in industrial cleaners as well as personal care, so check the product type before use.
