Ingredient review
C12-20 Alkyl Glucoside
INCI: C12-20 Alkyl Glucoside
A gentle, plant-based surfactant that effectively cleanses without disrupting the skin barrier, making it ideal for sensitive and dry skin types.
In plain English
C12-20 Alkyl Glucoside is a mild cleansing ingredient made from natural fatty alcohols (from coconut or palm oil) and glucose (from corn or wheat). It helps water mix with oil and dirt so they can be rinsed away, but it's much gentler than traditional sulfates like sodium lauryl sulfate. Because it doesn't strip the skin's natural moisture barrier, it leaves skin feeling clean but not tight or dry.

Quick decision guide
Easy yes for most routines
C12-20 Alkyl Glucoside 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 C12-20 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 renewable plant sources, combining fatty alcohols (C12–C20 chain length) with glucose. It belongs to the alkyl polyglucoside family, known for excellent mildness and biodegradability.
How it works
It reduces the surface tension between water and oil, allowing oils and dirt to be emulsified and rinsed away. Unlike harsher surfactants, it has a large, gentle molecular structure that interacts minimally with skin proteins, reducing irritation and preserving the skin's natural moisture barrier.
Pros
Ultra-gentle cleansing
Won't strip your skin's natural oils, helping maintain a healthy moisture barrier even with daily use.
Environmentally friendly
Made from renewable plant sources and fully biodegradable, reducing ecological impact compared to petroleum-based surfactants.
Cons and cautions
Lower foam volume
Produces a softer, creamier lather rather than big bubbles, which may not satisfy users who equate foam with cleansing power.
Less effective on heavy makeup
May require a double cleanse or an oil-based pre-cleanser to fully remove waterproof or long-wear products.
Best for
- People with dry, sensitive, or eczema-prone skin
- Anyone seeking a gentle, sulfate-free cleanser
Use caution if
- Those who prefer a very high-foam, squeaky-clean feel may find it too mild
Usage tips
Safety summary
C12-20 Alkyl Glucoside is considered very safe for cosmetic use. It has low irritation and sensitization potential, and no known toxicity concerns at typical usage levels. It is non-comedogenic and suitable for all skin types, including sensitive and compromised skin.
Research notes
Multiple studies confirm the mildness and skin compatibility of alkyl polyglucosides. They show significantly lower irritation and protein denaturation compared to sodium lauryl sulfate, making them a preferred choice for gentle cleansers. Their environmental safety is also well-documented.
Common label clues
- Typical concentration
- 1–15% depending on product type
- Regulatory status
- Approved for use in cosmetics worldwide, including by the EU CosIng database and the US FDA (as a generally recognized safe ingredient).
- Common uses
- Facial cleansers, Body washes, Shampoos, Makeup removers
- Environmental note
- Derived from renewable plant sources (coconut, palm, corn) and fully biodegradable, though palm sourcing should be certified sustainable to minimize deforestation impact.
Good to know
- Often labeled as 'alkyl polyglucoside' or 'APG' on ingredient lists.
- It is compatible with a wide pH range (5–7), making it easy to formulate in gentle, skin-friendly cleansers.
