Carbomer 934 (Emrapol) – Gel Thickener & Stabilizer

Carbomer 934 (Emrapol) from EMRAYS USA is the polymer that turns water into structure. A crosslinked polyacrylic acid, it swells dramatically upon neutralization to form a clear, smooth, stable gel network — the kind of elegant, non-stringy texture that defines premium skincare and oral care products. At concentrations as low as 0.2%, it builds viscosity that would take far higher levels of other thickeners to match.

What distinguishes this grade is its short-flow rheology — the gel it creates is smooth and spreadable, not ropy or stringy. It stays where you put it, spreads evenly, and delivers a clean, professional finish that consumers associate with high-quality formulations. Whether you’re building a lightweight serum, a rich face cream, or a toothpaste with just the right consistency, Carbomer 934 gives you the control to get it exactly right.

Key Benefits

Formulation Tips

Always disperse Carbomer in water before neutralization — sprinkle slowly into water with gentle stirring to avoid clumping. Neutralize with TEA (Triethanolamine) or NaOH to activate gel formation; the transformation is almost immediate. Avoid adding directly to oils without proper aqueous dispersion first. Works beautifully with humectants (glycerin, hyaluronic acid) and actives. For clear gels, use distilled or deionized water and avoid high electrolyte concentrations.
