Ingredient review
PPG-16/PEG-2 Lauryl Ether Sulfate
INCI: SODIUM PPG-16/PEG-2 LAURYL ETHER SULFATE
A mild-to-moderate synthetic cleanser that effectively removes dirt and oil but may cause irritation for sensitive skin.
In plain English
This ingredient is a synthetic surfactant, meaning it helps water mix with oil and dirt so they can be rinsed away. It's similar to other sulfate cleansers but modified with PPG and PEG groups to make it gentler on skin and hair. You'll find it in many shampoos and body washes where it creates foam and lifts away impurities.

Quick decision guide
Useful, but context matters
PPG-16/PEG-2 Lauryl Ether Sulfate 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 PPG-16/PEG-2 Lauryl Ether Sulfate.
- 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 modified sulfate surfactant where PPG (polypropylene glycol) and PEG (polyethylene glycol) chains are attached to lauryl ether sulfate. This modification reduces the harshness of traditional sulfates while maintaining cleansing power.
How it works
It works by reducing the surface tension between water and oil, allowing oils and dirt to be emulsified and rinsed away. The PPG/PEG groups add water-attracting and oil-attracting segments, making the molecule more balanced and less stripping than simpler sulfates.
Pros
Effective cleanser
Removes excess oil, dirt, and makeup without being as harsh as SLS, making it suitable for daily use on normal skin.
Good foam
Produces a rich, satisfying lather that many people associate with a thorough clean.
Cons and cautions
Potential irritation
Even with modifications, it can still cause stinging or dryness for those with sensitive or eczema-prone skin.
Synthetic origin
Not derived from natural sources, which may be a concern for consumers seeking plant-based or minimally processed ingredients.
Best for
- People with normal to oily skin looking for effective cleansing
- Those who prefer a foamy lather in their cleansers
Use caution if
- Individuals with very sensitive, dry, or compromised skin barriers
- Those seeking sulfate-free or all-natural formulations
Usage tips
Safety summary
Generally considered safe for use in rinse-off cosmetics at typical concentrations. Mild to moderate irritation risk, especially for sensitive skin. Not known to be comedogenic.
Research notes
Limited peer-reviewed studies specifically on this modified sulfate. Evidence is extrapolated from broader research on sulfate surfactants, which show that PPG/PEG modifications reduce irritation compared to SLS.
Common label clues
- Typical concentration
- 1–15% in rinse-off products
- Regulatory status
- Approved for use in cosmetics in the US, EU, and other major markets. Concentration limits may apply in rinse-off products.
- Common uses
- Shampoos, Body washes, Facial cleansers, Shower gels
- Environmental note
- Synthetic surfactants can be slow to biodegrade. Look for products with eco-friendly packaging or formulations that prioritize biodegradability.
Good to know
- The PPG and PEG modifications are added to reduce the irritation potential of standard sulfates.
- This ingredient is often used in combination with milder surfactants to balance cleansing power and gentleness.
