Ingredient review
Sodium Maleate Laurylglucoside Crosspolymer
INCI: SODIUM MALEATE LAURYLGLUCOSIDE CROSSPOLYMER
A mild, polymer-based cleanser that effectively removes dirt and oil without stripping the skin barrier.
In plain English
This ingredient is a gentle cleansing agent made by combining lauryl glucoside (a sugar-based cleanser from coconut and corn) with maleic acid. It forms a polymer that helps thicken products and create a soft, creamy lather. Because it's large and mild, it cleans without penetrating the skin deeply, reducing the risk of irritation.

Quick decision guide
Useful, but context matters
Sodium Maleate Laurylglucoside Crosspolymer 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 Maleate Laurylglucoside Crosspolymer.
- 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 polymer surfactant created by crosslinking lauryl glucoside (a non-ionic surfactant from renewable sources) with maleate groups. It functions as both a cleanser and a texture enhancer.
How it works
In a cosmetic product, this molecule surrounds dirt and oil with its water-loving and oil-loving parts, allowing them to be rinsed away. Its polymer structure also increases the viscosity of the formula, giving a thicker, more luxurious feel without harshness.
Pros
Very gentle on skin
Its large polymer structure means it doesn't penetrate deeply, making it ideal for sensitive or compromised skin barriers.
Improves formula feel
It thickens cleansers naturally, giving a creamy, pleasant texture without needing harsh thickeners.
Cons and cautions
Limited availability
This ingredient is less common in mass-market products, so you may need to check specialty or natural brands.
Moderate cleansing power
While excellent for daily use, it may struggle with heavy sunscreen or waterproof makeup, requiring a double-cleanse step.
Best for
- People with dry or sensitive skin looking for a sulfate-free cleanser
- Those who prefer mild, non-stripping cleansing for daily use
Use caution if
- Individuals seeking a very high-foaming or deep-cleansing experience may find it too gentle
Usage tips
Safety summary
Sodium Maleate Laurylglucoside Crosspolymer is considered safe for use in rinse-off cosmetics. It has low irritation and comedogenic potential, making it suitable for sensitive skin. No significant safety concerns have been reported in regulatory reviews.
Research notes
Research on this specific polymer is limited, but studies on related glucoside-based surfactants show they are mild and well-tolerated. The polymer form further reduces skin penetration, enhancing safety. Most evidence comes from ingredient safety databases and cosmetic chemistry literature.
Common label clues
- Typical concentration
- 1–5%
- Regulatory status
- Approved for use in cosmetics in the EU, US, and other major markets. No known restrictions at typical concentrations.
- Common uses
- Facial cleansers, Body washes, Shampoos, Makeup removers
- Environmental note
- Derived from plant-based lauryl glucoside (coconut and corn) and maleic acid. The polymer structure may reduce aquatic toxicity compared to traditional surfactants.
Good to know
- This ingredient is often found in 'low-pH' cleansers that help maintain the skin's acid mantle.
- It is biodegradable and derived from renewable plant sources, making it a more eco-friendly choice.
