Ingredient review
Sodium PEG-7 Olive Oil Carboxylate
INCI: SODIUM PEG-7 OLIVE OIL CARBOXYLATE
A mild, olive-oil-based surfactant that cleanses effectively while being gentle on the skin barrier.
In plain English
Sodium PEG-7 Olive Oil Carboxylate is a cleansing ingredient made from olive oil. It helps lift dirt, oil, and makeup from your skin so they can be rinsed away with water. Because it's derived from a natural oil and modified to be water-friendly, it tends to be much gentler than traditional harsh soaps, making it a good choice for sensitive or dry skin.

Quick decision guide
Useful, but context matters
Sodium PEG-7 Olive Oil 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 Sodium PEG-7 Olive Oil 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 semi-synthetic surfactant created by reacting olive oil with polyethylene glycol (PEG) and then converting it into a sodium salt. This process gives it both water-loving and oil-loving properties, allowing it to emulsify and remove impurities.
How it works
In a cosmetic product, it reduces the surface tension between water and oil, allowing oily dirt and makeup to be broken into tiny droplets that can be easily rinsed away. Its mildness comes from its large molecular structure, which is less likely to penetrate and irritate the skin.
Pros
Very gentle on skin
Its large molecular structure means it cleans without penetrating the skin barrier, reducing the risk of irritation and dryness.
Effective yet mild
It removes makeup, sunscreen, and excess oil thoroughly, but leaves skin feeling soft rather than tight or stripped.
Cons and cautions
Contains PEGs
PEG compounds are processed with ethylene oxide, which some consumers prefer to avoid due to potential contamination concerns, though cosmetic-grade PEGs are highly purified.
Not fully natural
Despite being derived from olive oil, the chemical modification means it is not considered a natural ingredient by clean beauty standards.
Best for
- People with dry or sensitive skin looking for a gentle cleanser
- Those who prefer plant-derived ingredients in their skincare routine
Use caution if
- Individuals who strictly avoid all PEG-derived ingredients in their cosmetics
Usage tips
Safety summary
Sodium PEG-7 Olive Oil Carboxylate is considered safe for use in cosmetics at typical concentrations. It has low irritation and comedogenic potential, making it suitable for sensitive skin. As with all PEG derivatives, purity standards ensure minimal contamination risks.
Research notes
Studies on PEG-modified olive oil derivatives indicate they are mild surfactants with good skin compatibility. The Cosmetic Ingredient Review (CIR) panel has evaluated similar PEG carboxylates and found them safe for cosmetic use.
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. PEG derivatives are regulated for purity and safety.
- Common uses
- Facial cleansers, Body washes, Makeup removers, Shampoos
- Environmental note
- Olive oil is a renewable resource, but the PEG modification process involves synthetic chemistry. Biodegradability is considered moderate.
Good to know
- Sodium PEG-7 Olive Oil Carboxylate is often used in micellar waters and gentle foaming cleansers.
- It is compatible with other mild surfactants to create a balanced cleansing formula.
