What Is Sodium Hydroxypropylphosphate Laurylglucoside Crosspolymer?
Sodium Hydroxypropylphosphate Laurylglucoside Crosspolymer is a plant-derived polymer made by taking laurylglucoside, a mild sugar-based surfactant from coconut or palm sources, and linking the molecules together with small phosphorus-containing bridges. The resulting network looks and feels different from the original surfactant, giving it new texturizing and stabilizing powers. The material was first developed in the early 2000s as brands searched for sulfate-free cleansers that could still give rich foam. By crosslinking laurylglucoside, chemists found they could keep the ingredient’s skin-friendly nature while boosting its performance.
The manufacturing process starts with laurylglucoside, which is reacted with 1,3-dichloro-2-propanol, then with bis(3-chloro-2-hydroxypropyl)phosphate. These steps stitch the small surfactant units into a three-dimensional polymer that disperses easily in water and salt solutions.
You will usually spot Sodium Hydroxypropylphosphate Laurylglucoside Crosspolymer in shampoos, body washes, facial cleansers, micellar waters, baby washes, bubble baths, liquid hand soaps and sometimes in light lotions or creams where extra foam or viscosity is desired.
Sodium Hydroxypropylphosphate Laurylglucoside Crosspolymer’s Cosmetic Benefits/Uses
This multi-tasking polymer supports a formula in several ways:
- Cleansing: Lifts away oil, dirt and sweat without stripping the skin’s natural barrier so products feel gentle yet effective
- Emulsifying: Helps water and oil phases stay blended which improves texture and keeps the formula stable on the shelf
- Foam Boosting: Builds a richer, creamier lather that makes washes and shampoos feel more indulgent even when they are sulfate-free
- Hydrotrope: Improves the solubility of other ingredients so actives and fragrances stay evenly dispersed and the product stays clear
Who Can Use Sodium Hydroxypropylphosphate Laurylglucoside Crosspolymer
This polymer is mild enough for most skin types including dry, oily, combination and sensitive because it cleanses without stripping away protective oils. People with extremely reactive or allergy-prone skin should still check ingredient lists for other potential triggers in the overall formula.
The material is plant derived from coconut or palm sugar and contains no animal by-products so it is suitable for vegans and vegetarians. It is also commonly used in cruelty-free product lines.
No safety concerns have been flagged for pregnant or breastfeeding women when the ingredient is used in rinse-off or leave-on cosmetics; however this is not medical advice and anyone who is pregnant or nursing should review any skincare or haircare routine with a qualified health professional, just to be safe.
Sodium Hydroxypropylphosphate Laurylglucoside Crosspolymer does not increase photosensitivity so there is no special need for extra sun protection beyond your regular habits. It is also considered color safe for dyed hair because it is sulfate free and low in harsh detergents.
Potential Side Effects/Adverse Reactions
Responses to topical Sodium Hydroxypropylphosphate Laurylglucoside Crosspolymer vary from person to person. The issues listed below are only potential outcomes and are unlikely for the average user when the ingredient is correctly formulated and used as directed.
- Mild eye irritation if the cleanser or shampoo accidentally gets into the eyes
- Transient skin redness or tingling in individuals with very sensitive skin
- Contact dermatitis in rare cases of allergy to sugar-based surfactants or trace manufacturing residues
- Dry or tight feeling if the product contains high levels of additional surfactants or if used excessively
If you experience stinging, rash or any lasting discomfort discontinue use and seek advice from a healthcare professional.
Comedogenic Rating
Rating: 0–1 (essentially non-comedogenic)
Sodium Hydroxypropylphosphate Laurylglucoside Crosspolymer is a large, water-soluble polymer that sits on the skin only briefly in most rinse-off products and does not block pores. It lacks oily or waxy residues that can trap sebum so the chance of clogging follicles is minimal. This makes it generally suitable for acne-prone or breakout-prone users. Because the ingredient is usually paired with other mild surfactants rather than heavy emollients, the overall formula tends to rinse clean without leaving pore-blocking films.
Summary
Sodium Hydroxypropylphosphate Laurylglucoside Crosspolymer acts as a gentle cleanser, foam booster, emulsifier, viscosity builder and hydrotrope. By crosslinking plant-derived laurylglucoside into a three-dimensional network it grabs onto oil and dirt, stabilises oil-water mixtures, thickens watery bases and lifts the richness of lather while keeping formulas clear and sulfate free.
Although not yet a household name it has gained steady popularity in natural-leaning shampoos, body washes and facial cleansers that aim for a creamy feel without harsh sulfates. Brands appreciate its ability to improve texture and foam while staying gentle, so its presence on ingredient lists is rising.
The current safety data show low irritation and a very low risk of pore clogging which makes it appropriate for most skin and hair types. As with any new cosmetic it is wise to patch test the finished product first and monitor how your skin responds.
