What Is Sodium Hydroxypropylsulfonate Decylglucoside Crosspolymer?
Sodium Hydroxypropylsulfonate Decylglucoside Crosspolymer is a plant-derived ingredient created by linking the gentle sugar-based cleanser decyl glucoside with small connecting molecules, then adding sulfonate groups that improve its water affinity. The process starts with glucose obtained from corn or other starch sources and decyl alcohol from coconut or palm kernels to make decyl glucoside. Chemists react this surfactant with 1,3-dichloro-2-propanol to form a three-dimensional network, then treat it with 3-chloro-2-hydroxypropyl sulfonate to introduce the sodium sulfonate sites. The result is a large, water-loving polymer that performs better than simple surfactants on their own.
The ingredient was developed in the early 2000s as brands looked for alternatives to sulfates that could still deliver rich foam and easy rinsing. Because it is mild and often sourced from renewable plants, it fits well with modern clean-beauty trends.
You will most often see Sodium Hydroxypropylsulfonate Decylglucoside Crosspolymer in facial cleansers, body washes, micellar waters, foaming shampoos, bubble baths and even some makeup removers. Formulators also add it to creamy masks and exfoliating scrubs when they want a product that rinses away without leaving a film.
Sodium Hydroxypropylsulfonate Decylglucoside Crosspolymer’s Cosmetic Benefits/Uses
This multitasker improves both how a product works and how it feels on the skin or hair
- Cleansing: Lifts dirt, oil and makeup so they can be washed off easily, yet it remains mild enough for daily use and sensitive skin
- Emulsifying: Helps water and oil mix smoothly which keeps lotions and creams stable and prevents separation during shelf life
- Foam Boosting: Builds a richer creamier lather that makes cleansing feel more luxurious and gives users visual feedback that the product is working
- Hydrotrope: Improves the solubility of other ingredients so formulas stay clear and free from residue even at higher fragrance or oil levels
Who Can Use Sodium Hydroxypropylsulfonate Decylglucoside Crosspolymer
This gentle surfactant suits most skin types including dry, combination, oily and even sensitive skin because its large polymer structure cleans without stripping the skin’s natural barrier. People with very reactive or compromised skin can usually tolerate it, though they should still pay attention to the overall formula since other ingredients might be harsher.
The raw materials come from plant sources like corn sugar and coconut or palm kernel alcohol, and no animal by-products are introduced during manufacturing. For that reason products relying on this ingredient are typically acceptable to vegans and vegetarians, provided the rest of the formula also meets their standards.
Sodium Hydroxypropylsulfonate Decylglucoside Crosspolymer is not known to penetrate deeply or interfere with hormones so it is generally considered safe for use during pregnancy or while breastfeeding. This is not medical advice and anyone who is pregnant or nursing should have a doctor review their skin care routine to be safe.
The molecule does not make skin more sensitive to sunlight and does not degrade under UV exposure, so it does not add any risk of photosensitivity.
Potential Side Effects/Adverse Reactions
Reactions can vary from person to person. The points below list potential side effects but they are uncommon and most users experience none when the ingredient is properly formulated and used as directed.
- Mild eye irritation if the cleanser accidentally gets into the eyes
- Transient redness or stinging on very sensitive skin, especially if the product is left on for longer than directed
- Dryness or tightness when used in high concentrations or paired with other strong surfactants
- Allergic contact dermatitis in rare cases for individuals allergic to sugar-derived surfactants
If any irritation or discomfort occurs the user should stop applying the product and consult a healthcare professional.
Comedogenic Rating
Rating: 0 / 5
Sodium Hydroxypropylsulfonate Decylglucoside Crosspolymer is a large water soluble molecule that stays on the skin only for the short time it takes to cleanse then rinses away completely. It has no oily or waxy parts that could settle in pores so it does not form the plugs that lead to blackheads or pimples.
Because of this it is considered suitable for people who are prone to acne or frequent breakouts.
The ingredient can even help remove leftover makeup oils that might otherwise clog pores, which adds a small extra benefit for acne prone users.
Summary
Sodium Hydroxypropylsulfonate Decylglucoside Crosspolymer acts as a gentle cleanser, emulsifier, foam booster and hydrotrope. Its sugar based backbone grabs dirt and oil while the sulfonate sites pull everything into water so the mess rinses off easily. The crosslinked structure creates rich stable foam that feels silky and helps water and oil blend smoothly, keeping products clear and uniform.
Although it is not yet as famous as classic surfactants like SLS, its plant origin and mild profile have made it a rising star in sulfate free face and body care. More brands add it each year as shoppers look for skin friendly alternatives.
Current research and decades of safe use show a very low risk of irritation or systemic harm. Still every skin is unique so it is smart to patch test any new product that contains this or any other active ingredient.
