INCI: C10-16 Alkyl Glucoside
A gentle, plant-based surfactant that effectively cleanses without stripping the skin's natural moisture barrier.
In plain English
C10-16 Alkyl Glucoside is a mild cleansing ingredient made from natural sources like coconut or palm oil and sugar. It helps remove dirt, oil, and makeup from your skin and hair without being harsh or drying. Unlike some traditional sulfates, it is known for being gentle and is often used in products for sensitive 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 C10-16 Alkyl Glucoside.
- 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
strongThere is a stronger practical or research basis for the ingredient role described here.
What it is
A non-ionic surfactant derived from fatty alcohols (C10-16 chain length) and glucose (sugar). It belongs to the alkyl polyglucoside family, which are known for their mildness and biodegradability.
How it works
It works by reducing the surface tension between water and oil, allowing oil and dirt to be lifted away from the skin and rinsed off with water. Its large molecular structure makes it less penetrating and less irritating than smaller, harsher surfactants.
Pros
Very gentle on skin
Its large molecular structure means it doesn't penetrate deeply, reducing irritation and making it ideal for sensitive skin.
Environmentally friendly
Made from renewable plant sources and is readily biodegradable, making it a greener choice compared to many synthetic surfactants.
Cons and cautions
Can be slightly drying at high levels
In very high concentrations or in products without enough moisturizing ingredients, it may still leave very dry skin feeling tight.
Sourcing concerns
Often derived from palm oil, which can be associated with deforestation unless certified sustainable palm oil is used.
Best for
- People with sensitive or reactive skin
- Those looking for sulfate-free cleansers
- Individuals with dry or eczema-prone skin
Use caution if
- Those with a known allergy to coconut or palm derivatives (rare)
