Methyl Glucose Sesquicocoate
INCI: Methyl Glucose Sesquicocoate
A mild, coconut-derived surfactant that cleanses effectively while being gentle on the skin barrier.
In plain English
Methyl Glucose Sesquicocoate is a cleansing ingredient made from glucose (a sugar) and coconut oil fatty acids. It works like a gentle soap, helping water mix with oil and dirt so they can be rinsed away. Unlike harsher detergents, it cleans without stripping your skin's natural moisture, making it a favorite for sensitive or dry skin types.

Quick decision guide
Easy yes for most routines
Methyl Glucose Sesquicocoate 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 Methyl Glucose Sesquicocoate.
- 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 non-ionic surfactant derived from methyl glucose (a sugar derivative) and coconut oil fatty acids. It belongs to the alkyl glucoside family, known for mild cleansing.
How it works
It reduces the surface tension between water and oil, allowing impurities and sebum to be emulsified and rinsed off. Its large molecular structure makes it less penetrating and less irritating than smaller surfactants.
Pros
Exceptionally mild
Its large molecular structure means it doesn't penetrate the skin deeply, reducing the risk of irritation and dryness.
Eco-friendly profile
Made from renewable glucose and coconut oil, it is biodegradable and has a lower environmental impact than many petroleum-based surfactants.
Cons and cautions
Moderate lather
It produces a creamy but not very bubbly foam, which may not satisfy those who associate foam with cleansing power.
Limited solo cleansing strength
For heavy makeup or long-wear sunscreen, it often needs to be paired with other surfactants or used in a double-cleanse routine.
Best for
- People with dry, sensitive, or eczema-prone skin who need a gentle cleanser
- Anyone looking for a more natural, plant-derived cleansing option
Use caution if
- Those who prefer a very foamy, bubbly cleanser may find it too mild
Usage tips
Safety summary
Considered very safe for topical use. It has low irritation and sensitization potential, and no significant toxicity concerns at typical cosmetic concentrations.
Research notes
While not as extensively studied as some common surfactants, the alkyl glucoside family is well-documented for mildness. Studies show these surfactants cause less protein denaturation and lipid barrier disruption than sodium lauryl sulfate.
Common label clues
- Typical concentration
- 1–10% in rinse-off products
- Regulatory status
- Approved for use in cosmetics globally, including by the EU CosIng database and the US FDA as a safe surfactant.
- Common uses
- Cleansers, Body washes, Shampoos, Facial washes
- Environmental note
- Derived from renewable plant sources (glucose and coconut oil) and readily biodegradable, making it a more sustainable choice than many synthetic surfactants.
Good to know
- It is often listed near the middle or end of ingredient lists because it is used at lower concentrations.
- Despite the 'cocoate' name, it does not contain coconut protein and is generally safe for coconut-allergic individuals (always patch test if concerned).
