PEG-8 Palm Glycerides Sulfosuccinate
INCI: DISODIUM PEG-8 PALM GLYCERIDES SULFOSUCCINATE
A gentle, sulfate-free surfactant that cleanses effectively while being kind to sensitive skin.
In plain English
This ingredient is a mild soap-like molecule that helps water mix with oil and dirt so they can be rinsed away. It's often used in 'gentle' or 'sulfate-free' cleansers because it cleans without making your skin feel tight or dry. Think of it as a kinder alternative to harsher detergents like sodium lauryl sulfate.

Quick decision guide
Useful, but context matters
PEG-8 Palm Glycerides Sulfosuccinate 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 PEG-8 Palm Glycerides Sulfosuccinate.
- 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 made by combining palm glycerides (fats from palm oil) with PEG-8 (a polyethylene glycol chain) and sulfosuccinate (a mild cleansing group). It belongs to the sulfosuccinate family, known for being gentle on skin and eyes.
How it works
It reduces the surface tension between water and oil, allowing impurities and excess sebum to be lifted from the skin and washed away. Its large molecular structure makes it less penetrating and less irritating than smaller surfactants.
Pros
Very gentle on skin
Its large molecular structure means it sits on the skin's surface rather than penetrating, reducing irritation and dryness.
Sulfate-free alternative
Provides effective cleansing without the harshness of sodium lauryl sulfate, making it ideal for daily use on sensitive skin.
Cons and cautions
Palm oil sourcing
Derived from palm oil, which can contribute to deforestation unless sourced from certified sustainable plantations.
Moderate cleansing power
May not thoroughly remove heavy makeup or waterproof sunscreen, often requiring a double-cleansing step.
Best for
- People with dry or sensitive skin
- Those looking for a sulfate-free cleanser
- Individuals with eczema or rosacea-prone skin
Use caution if
- Those strictly avoiding all PEG compounds (rare sensitivity)
- Anyone with a known allergy to palm-derived ingredients
Usage tips
Safety summary
Considered safe for cosmetic use at typical concentrations. Low irritation and comedogenic risk. Some individuals with PEG sensitivity may react, but this is rare. Always patch test if you have very reactive skin.
Research notes
Sulfosuccinates are well-studied as mild surfactants. Research shows they cause less skin barrier disruption compared to sodium lauryl sulfate. Specific studies on this exact compound are limited, but the class is widely accepted as safe.
Common label clues
- Typical concentration
- 1–10% in rinse-off products
- Regulatory status
- Approved for use in cosmetics in the US (FDA), EU (CosIng), and many other regions. Generally recognized as safe when used as directed.
- Common uses
- Facial cleansers, Body washes, Shampoos, Baby care products
- Environmental note
- Palm oil sourcing can impact rainforests; look for products with RSPO (Roundtable on Sustainable Palm Oil) certification to support sustainable practices.
Good to know
- Often listed as 'disodium PEG-8 palm glycerides sulfosuccinate' on labels.
- Commonly found in 'gentle' or 'sensitive skin' formulas.
- PEG compounds are processed to be safe for cosmetic use.
