Ingredient review
Sodium Carboxymethyl C10-16 Alkyl Glucoside
INCI: SODIUM CARBOXYMETHYL C10-16 ALKYL GLUCOSIDE
A gentle, effective cleanser derived from natural sugars and fatty alcohols, ideal for sensitive skin.
In plain English
This ingredient is a mild soap-like molecule made from plant sugars and coconut-derived fatty alcohols. It helps water mix with oil and dirt so they can be rinsed away, but it's much gentler than traditional sulfates, making it a favorite for sensitive or dry skin.

Quick decision guide
Easy yes for most routines
Sodium Carboxymethyl C10-16 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 Sodium Carboxymethyl 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
moderateThere is useful support, but formula details and claim strength still matter.
What it is
A semi-synthetic surfactant created by chemically modifying glucose (from corn or potato starch) with fatty alcohols from coconut or palm oil, then adding a carboxymethyl group to improve its cleansing power and mildness.
How it works
It has a water-loving head and an oil-loving tail. When you wash, the tails grab onto oils and dirt while the heads stay in water, forming tiny droplets that rinse away easily. This process cleans without disrupting the skin's natural moisture barrier as much as harsher surfactants.
Pros
Ultra-gentle cleansing
Unlike sodium lauryl sulfate, this surfactant cleans without stripping the skin's natural oils, helping maintain a healthy moisture barrier.
Plant-derived and biodegradable
Made from renewable sources like corn and coconut, it breaks down easily in the environment, making it a more eco-friendly choice.
Cons and cautions
Less effective on heavy makeup
If you wear long-wear or waterproof cosmetics, you may need a double-cleanse routine or a stronger first cleanser.
Can feel slightly filmy
Some users report a light residue after rinsing, especially in hard water areas, which may require extra rinsing.
Best for
- People with dry, sensitive, or eczema-prone skin looking for a non-stripping cleanser
- Anyone seeking a sulfate-free, plant-based cleansing option
Use caution if
- Those who prefer a high-foam, squeaky-clean feel may find it too mild
Usage tips
