What Is Sodium Maleate Laurylglucoside Crosspolymer?
Sodium Maleate Laurylglucoside Crosspolymer is a plant-derived surfactant made by linking lauryl glucoside, a sugar and coconut or palm-based alcohol blend, with 1,3-dichloro-2-propanol. The resulting network is then reacted with maleic anhydride and partly neutralized with sodium hydroxide to form a stable, water-friendly polymer. This extra crosslinking turns a simple cleanser into a more robust ingredient that behaves well in modern rinse-off formulas.
Mild, sugar-based cleansers grew popular in the 1990s when brands looked for alternatives to harsher sulfates. Chemists discovered that crosslinking lauryl glucoside improved texture, viscosity control and foam quality, so Sodium Maleate Laurylglucoside Crosspolymer began showing up in commercial shampoos and body washes in the early 2000s. Today it appears in a wide range of everyday products such as facial cleansers, micellar waters, foaming masks, bubble baths, baby washes and sulfate-free shampoos where a mild yet effective lather is desired.
Sodium Maleate Laurylglucoside Crosspolymer’s Cosmetic Benefits/Uses
This multifunctional polymer gives formulators a few key advantages:
- Cleansing: Lifts dirt, oil and makeup from skin or hair while remaining gentle so it suits sensitive or frequent-wash routines
- Foam boosting: Increases both the amount and stability of lather, letting products feel richer and rinse away more easily
Who Can Use Sodium Maleate Laurylglucoside Crosspolymer
Because it is a gentle sugar based surfactant this ingredient suits most skin types including normal, oily, dry, combination and sensitive skin. People with very reactive or damaged skin usually tolerate it well since it is less stripping than traditional sulfates.
Sodium Maleate Laurylglucoside Crosspolymer is produced from plant sources such as coconut or palm so it contains no animal derived material. This makes it acceptable for both vegans and vegetarians.
No data point to risks for women who are pregnant or breastfeeding when the ingredient is used in rinse off cosmetics. That said this is not medical advice and expectant or nursing mothers should show any product they plan to use to a qualified health professional first.
The polymer does not cause photosensitivity and it plays well with other common skincare ingredients. It is also gluten free and fragrance free in its raw form which can be helpful for users watching for those triggers.
Potential Side Effects/Adverse Reactions
Reactions to topical Sodium Maleate Laurylglucoside Crosspolymer can differ from person to person. The issues listed below are only potential effects and are unlikely for most users when products are formulated correctly.
- Mild irritation or redness if the skin is extremely sensitive or the product is left on for longer than directed
- Eye stinging should the cleanser accidentally get into the eyes during use
- Allergic contact dermatitis in the rare case of hypersensitivity to coconut or corn derived ingredients
- Dryness when very high concentrations are used or when combined with hard water
If any of these effects occur discontinue use and seek medical advice if symptoms do not quickly improve.
Comedogenic Rating
Rating: 0 / 5
Sodium Maleate Laurylglucoside Crosspolymer is highly water soluble and designed for rinse-off formulas so it does not linger in pores. It has no oily or waxy residues that could trap sebum or dead cells therefore the risk of clogging pores is virtually nil. This makes it suitable for people who are prone to acne or breakouts.
Because it is normally used at low levels in shampoos, body washes and facial cleansers any chance of pore blockage is further reduced. The only time a higher rating might apply is if a formula also contained heavy emollients that remain on skin after rinsing.
Summary
Sodium Maleate Laurylglucoside Crosspolymer is a mild sugar-based surfactant that cleanses by surrounding dirt and oil so they rinse away with water. Its crosslinked structure stabilises bubbles and enhances foam so products feel creamy and rinse clean without stripping. Those same links also lend a bit of viscosity control, helping formulators hit the sweet spot between watery and too thick.
It enjoys steady popularity in sulfate-free shampoos, baby washes and gentle facial cleansers though it has not reached the household-name status of classic sulfates or cocamidopropyl betaine.
Current safety data show a very low risk of irritation or sensitisation when used as directed. Still, every skin is unique so it is wise to try a small patch of any new product before full use.
