Ingredient review
MEA-PPG-8 Steareth-7 Carboxylate
INCI: MEA-PPG-8-STEARETH-7 CARBOXYLATE
A gentle synthetic surfactant that cleanses without stripping the skin, often used in sulfate-free and sensitive-skin formulas.
In plain English
This ingredient is a mild cleansing agent made from a combination of fatty acids and propylene glycol. It helps water mix with oil and dirt so they can be rinsed away, but it's much gentler than traditional sulfates. You'll find it in cleansers and shampoos that claim to be 'gentle' or 'for sensitive skin.'

Quick decision guide
Useful, but context matters
MEA-PPG-8 Steareth-7 Carboxylate is generally a lower-concern ingredient when the full formula suits your skin.
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 MEA-PPG-8 Steareth-7 Carboxylate.
- 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
lowLess likely to sting, burn, or bother most users, though sensitive skin can still react.
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 surfactant (cleansing agent) created by reacting a fatty alcohol derivative with propylene glycol and a carboxylate group. It belongs to the ether carboxylate family, known for mildness.
How it works
It reduces the surface tension between water and oil, allowing oils and dirt to be lifted from the skin and rinsed away. Its large molecular structure makes it less penetrating and less irritating than smaller surfactants like sodium lauryl sulfate.
Pros
Very gentle on skin
Its large molecular structure means it stays mostly on the surface, so it cleans without stripping the skin's natural moisture barrier.
Versatile in formulations
Works well in both rinse-off and leave-on products, and can help reduce irritation when combined with stronger surfactants.
Cons and cautions
Synthetic origin
It is not derived from natural sources, which may be a drawback for consumers seeking 'clean' or 'natural' beauty products.
Less common in consumer awareness
Because it's not as widely used as coco-glucoside or sodium lauryl sulfate, there is less independent research on its long-term skin effects.
Best for
- People with dry or sensitive skin looking for a non-stripping cleanser
- Anyone wanting a sulfate-free shampoo or body wash
Use caution if
- Those who strictly avoid all synthetic ingredients
Usage tips
Safety summary
Considered safe for use in cosmetics at typical concentrations. It has low irritation and sensitization potential, making it suitable for sensitive skin. No significant safety concerns have been raised by regulatory bodies.
Research notes
Ether carboxylates as a class are well-studied for mildness and low irritation. Specific data on MEA-PPG-8 Steareth-7 Carboxylate is limited, but its chemical relatives show good skin compatibility. Most evidence comes from manufacturer safety data and general surfactant research.
Common label clues
- Typical concentration
- 1–10% in rinse-off products; lower in leave-on formulas
- Regulatory status
- Approved for use in cosmetics in the EU, US, and other major markets. No specific restrictions beyond general cosmetic safety requirements.
- Common uses
- Facial cleansers, Body washes, Shampoos, Makeup removers
- Environmental note
- As a synthetic surfactant, its biodegradability varies by formulation. Some ether carboxylates are readily biodegradable, but check individual product claims.
Good to know
- This ingredient is often used in 'low-irritation' baby shampoos and facial cleansers.
- It is not a foaming powerhouse, so products with it may produce a less rich lather.
