Ingredient review
Sodium Decylglucosides Hydroxypropylsulfonate
INCI: Sodium Decylglucosides Hydroxypropylsulfonate
A gentle, sulfate-free surfactant that effectively cleanses without stripping the skin or scalp.
In plain English
This ingredient is a mild cleansing agent made from plant-derived glucose (sugar) and fatty alcohols. It helps water mix with dirt and oil so they can be rinsed away, but it's much less harsh than traditional sulfates like sodium lauryl sulfate. It's often used in 'gentle' or 'sensitive skin' cleansers because it cleans without leaving skin feeling tight or dry.

Quick decision guide
Useful, but context matters
Sodium Decylglucosides Hydroxypropylsulfonate 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 Decylglucosides Hydroxypropylsulfonate.
- 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 modified version of decyl glucoside, a non-ionic surfactant derived from coconut oil and corn sugar. The hydroxypropylsulfonate group is added to improve its mildness and water solubility.
How it works
It lowers the surface tension between water and oil, allowing impurities and excess sebum to be emulsified and washed away. Its large molecular structure makes it less penetrating into the skin barrier, reducing irritation potential.
Pros
Very gentle on skin
Its large molecular structure means it doesn't easily penetrate the skin barrier, reducing the risk of irritation and dryness compared to harsher surfactants.
Sulfate-free and eco-friendly
Derived from renewable plant sources (coconut and corn) and biodegradable, making it a more sustainable choice for daily cleansing.
Cons and cautions
Low foam profile
Produces a creamy, low lather that some users may mistake for insufficient cleansing, though it is still effective at removing dirt and oil.
Potential for slight dryness at high levels
In formulas where it is the primary surfactant at high concentrations, it can still cause mild dryness, especially for very dehydrated skin.
Best for
- People with dry or sensitive skin looking for a mild cleanser
- Those avoiding sulfates for scalp or skin health
Use caution if
- Individuals who prefer high-foam, bubbly cleansers (this ingredient produces a low, creamy lather)
Usage tips
Safety summary
Sodium decylglucosides hydroxypropylsulfonate is considered safe for use in cosmetics at typical concentrations. It has low irritation and sensitization potential, making it suitable for sensitive skin. No significant safety concerns have been reported in regulatory reviews.
Research notes
Studies on similar alkyl glucoside surfactants show they are mild to the skin barrier and have low cytotoxicity. Specific research on the hydroxypropylsulfonate variant is limited, but its chemical structure supports a favorable safety profile.
