Ingredient review
Disodium Palmitoleamido PEG-2 Sulfosuccinate
INCI: DISODIUM PALMITOLEAMIDO PEG-2 SULFOSUCCINATE
A gentle, sulfate-free surfactant that cleanses effectively while being kind to sensitive and dry 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 is often used in 'gentle' or 'sulfate-free' cleansers because it cleans without making the 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
Disodium Palmitoleamido PEG-2 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 Disodium Palmitoleamido PEG-2 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 created by combining palmitoleic acid (a fatty acid found in macadamia nut oil and human sebum) with PEG (polyethylene glycol) and sulfosuccinate. It belongs to the sulfosuccinate family, known for mild cleansing.
How it works
Its molecular structure has a water-loving head and an oil-loving tail. When you wash, the tails grab onto oils and dirt, while the heads stay in the water, allowing everything to be rinsed away. Because it is large and gentle, it does not penetrate the skin barrier easily, reducing irritation.
Pros
Very gentle on skin
Its large molecular structure means it stays on the surface and doesn't penetrate the skin barrier, making it ideal for sensitive or compromised skin.
Sulfate-free alternative
Provides effective cleansing without the harshness of sodium lauryl sulfate or sodium laureth sulfate, reducing the risk of dryness and irritation.
Cons and cautions
Less effective on heavy buildup
May struggle to remove thick waterproof makeup or heavy sunscreen, requiring a double-cleansing routine.
PEG-related purity concerns
As a PEG derivative, there is a theoretical risk of contamination with 1,4-dioxane during manufacturing, though reputable suppliers purify their ingredients to safe levels.
Best for
- People with dry or sensitive skin looking for a gentle cleanser
- Those who prefer sulfate-free or mild cleansing products
Use caution if
- Individuals with known allergies to PEG compounds (rare)
- Those needing a deep-cleansing product for heavy makeup or oil control
Usage tips
Safety summary
Disodium Palmitoleamido PEG-2 Sulfosuccinate is considered safe for use in rinse-off cosmetics at typical concentrations. It has a low irritation and comedogenic risk, making it suitable for sensitive skin. As with all PEG derivatives, quality control during manufacturing is important to minimize potential impurities.
Research notes
Sulfosuccinates as a class are well-studied for mildness and low irritation potential. Specific studies on this exact ingredient are limited, but its chemical relatives (e.g., disodium laureth sulfosuccinate) have been evaluated by the Cosmetic Ingredient Review (CIR) panel and found safe for use in cosmetics.
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 other major markets. No specific restrictions beyond general cosmetic safety requirements.
- Common uses
- Facial cleansers, Body washes, Shampoos, Baby products
- Environmental note
- Sulfosuccinates are generally considered more biodegradable than some other surfactants, but PEG-based ingredients may have persistence concerns in aquatic environments.
Good to know
- Palmitoleic acid is a monounsaturated fatty acid naturally found in human sebum and macadamia nut oil.
- Sulfosuccinates are generally considered biodegradable and more environmentally friendly than some traditional surfactants.
