Carbopol® Ultrez 20 polymer is a hydrophobically-modified, cross-linked acrylate copolymer that’s revolutionized the way formulators create creams, gels, shampoos, and lotions.

Why It’s a Game-Changer
Effortless Incorporation
Being self-wetting, it disperses in water in minutes without vigorous agitation, saving hours in production time prod.lubrizol.com+4lubrizol.com+4Pharma Excipients+4.Electrolyte & Surfactant Friendly
Unlike traditional carbomers that destabilize easily, Ultrez 20 tolerates up to ~10–12% surfactants and significant electrolytes, making it ideal for shampoos, shower gels, and botanical-rich formulas .Rich Texture & Clarity
It delivers a silky, luxurious skin feel in emulsions and emulsified a clear gel even in hydroalcoholic systems—appealing to both formulators and consumers knowde.com+7treasureactives.com+7Dermafactors+7prod.lubrizol.com+10lubrizol.com+10Pharma Excipients+10.Stabilizes Actives & Beads
This polymer suspends microbeads, microcapsules, and exfoliants, preventing separation and ensuring consistency in visual products like scrubs and gel masks knowde.com+7lubrizol.com+7newdirectionsaromatics.ca+7.Broad pH Window
Unlike many thickeners, it remains stable from pH 4 to 9, enabling flexible formulation paths from acidic cleansers to mildly alkaline gels Reddit+10treasureactives.com+10knowde.com+10.

🛠️ How to Formulate with Ultrez 20
Dispersion
Sprinkle onto water and allow self-wetting for ~5 minutes Dermafactors+2treasureactives.com+2knowde.com+2.Gentle Mixing
Begin low-speed stirring—avoid foam to preserve clarity.Incorporate Surfactants
Add after wetting to keep viscosity stable.Neutralization
Use TEA, NaOH, or AMP to elevate pH (~6.5–7.5) and activate thickening knowde.comReddit.Add Oils/Actives
Once neutralized, incorporate oils, botanicals, or humectants; viscosity remains stable.Adjust Final pH
Keep within 4–9 to maintain thickening and clarity.
✨ Benefit Insights
Fast Processing: Self-wetting eliminates need for prolonged mixing.
Clear vs. Creamy Flexibility: Adapt texture depending on product type (gel vs. lotion).
Improved Sensory Feel: Creates richer rubout in creams, more slip in body washes newdirectionsaromatics.caReddit+5Reddit+5treasureactives.com+5Dermafactors+7lubrizol.com+7knowde.com+7.
Stable with Humectants: Blends well in formulas with glycerin, sodium PCA, etc., thanks to strong electrolyte tolerance.
Actives Carriage: Great for suspending beads, microspheres, SPF particles—ideal for premium formulas.

⚠️ Formulation Tips & Common Pitfalls
Neutralization is Critical
Maintain precise pH (6.5–7.5); avoid foaming during neutralizer addition ahualyn.com+5lubrizol.com+5Pharma Excipients+5theformulatorshop.com+3Pharma Excipients+3Dermafactors+3.Electrolyte Caution
Though tolerant, extremely high salt levels (>2%) may reduce viscosity; test each batch.Avoid Over-Agitation
Heavy shear can create foam and reduce clarity; use gentle mixing.pH Must Stay Consistent
Keep pH steady to preserve gel; drifting pH can thin the gel structure treasureactives.comknowde.com.
