Ingredient review
Coco Glucoside Crosspolymer
INCI: Sodium Hydroxypropylsulfonate Cocoglucoside Crosspolymer
A mild, plant-based cleansing polymer that helps create a creamy, non-stripping lather — great for sensitive or dry skin.
In plain English
This ingredient is a modified version of coco glucoside, a gentle cleanser made from coconut oil and fruit sugars. The crosspolymer part means it has been chemically linked into larger molecules, which makes it even milder and helps thicken the product so it feels luxurious on your skin. It cleans without stripping away your skin's natural moisture barrier.

Quick decision guide
Easy yes for most routines
Coco Glucoside 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 Coco Glucoside 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 derived from coconut oil and glucose (fruit sugar), chemically modified to be extra gentle and to help control the thickness of liquid cleansers.
How it works
It acts as a surfactant, meaning it helps water mix with oil and dirt so they can be rinsed away. Because it's a crosspolymer, it forms a larger molecular structure that is too big to penetrate the skin deeply, so it stays on the surface and cleans without irritation. It also helps create a stable, creamy foam and thickens the product's texture.
Pros
Ultra-gentle cleansing
Its large molecular structure means it cleans without penetrating or irritating the skin, making it ideal for compromised or sensitive skin barriers.
Sulfate-free texture booster
It thickens formulas naturally, giving a creamy, luxurious feel without the need for harsh sulfates or synthetic thickeners.
Cons and cautions
Low foam volume
If you love a big, bubbly lather, this ingredient produces a more subtle, creamy foam that some find less satisfying.
Potential heaviness on oily skin
In high concentrations, it can leave a slight film that might feel too rich for very oily or acne-prone skin types.
Best for
- People with sensitive, dry, or eczema-prone skin
- Anyone looking for a sulfate-free, gentle cleanser
Use caution if
- Those who prefer a very bubbly, high-foam cleanser (this is low-foaming)
Usage tips
Safety summary
Considered very safe for topical use. It has a low irritation and comedogenic risk, and is well-tolerated even by sensitive skin. No significant safety concerns have been reported in cosmetic use.
Research notes
While specific studies on this exact crosspolymer are limited, the parent surfactant coco glucoside has been extensively reviewed and found to be safe and mild. The crosspolymer modification further reduces irritation potential. Industry data supports its use as a gentle cleanser.
Common label clues
- Typical concentration
- 1–5% in rinse-off formulas
- Regulatory status
- Approved for use in cosmetics in the EU, US, and most major markets. No known restrictions at typical use levels.
- Common uses
- Facial cleansers, Body washes, Shampoos, Baby care products
- Environmental note
- Derived from renewable plant sources (coconut and corn) and is readily biodegradable, making it a more sustainable choice than petroleum-based surfactants.
Good to know
- This ingredient is often used in 'no-tear' baby shampoos because of its mildness.
- It is biodegradable and considered environmentally friendlier than many synthetic surfactants.
