What Is Carbomer 940?
Carbomer 940 is a high-molecular-weight cross-linked polyacrylic acid polymer, which is one of the most classic gelling thickeners for water-based cosmetics. In its raw powder state, it disperses in water and swells to form an acidic low-viscosity dispersion. After neutralization by alkaline agents such as triethanolamine, sodium hydroxide or AMP-95, the carboxyl groups on molecular chains dissociate, polymer chains stretch to build three-dimensional water-locking network, forming highly transparent, elastic and high-viscosity gel systems.
Different from natural polysaccharide thickener xanthan gum, Carbomer 940 achieves ultra-high thickening efficiency at very low dosage, produces crystal-clear gel with short-flow rheology, excellent suspension performance, but its viscosity is sensitive to electrolytes and salts, must be neutralized to obtain effective viscosity. Aogebio supplies high-purity cosmetic-grade Carbomer 940 in bulk, offering free samples, full qualification documents and global one-stop shipping services for cosmetic manufacturers.
Core Advantages Of Our Carbomer 940
High-Purified Fine Powder Quality
Multi-step purification treatment, low residual solvent, uniform fluffy fine powder, reduce agglomeration risk during water-phase dispersion, suitable for high-grade transparent gel and clean-beauty cosmetic formulas.
Ultra-Efficient Thickening & Crystal-Clear Gel Performance
Obtain high-viscosity transparent gel under low addition amount, neutralized gel shows excellent light transmittance, no turbidity or haze, ideal raw material for transparent skincare gel and styling gel.
Powerful Suspending & Stabilizing Capacity
High yield value characteristic, capable of stably suspending insoluble particles, plant beads, pigments and UV physical filters; reinforce O/W emulsion structure to prevent oil-water phase separation of lotion and cream products.
Short-Flow Rheology & Comfortable Skin Feel
Features short-flow property: gel keeps shape without flowing when static; easy to spread smoothly on skin, bring fresh, non-sticky skin feel without greasy residue.
Good Compatibility With Common Cosmetic Ingredients
Compatible with polyols, most non-ionic emulsifiers, various water-soluble skincare actives, adapts to multiple water-leave-on and rinse-off cosmetic systems.
Stable Batch Quality & Flexible Supply
Consistent batch-to-batch viscosity and transparency indicators, fit for large-scale industrial production; support sample testing, small-batch trial order and large-volume bulk customization.
How Carbomer 940 Works In Cosmetic Formulations
Carbomer 940 powder absorbs water and swells in water phase, molecular chain curls and presents low viscosity under acidic condition before neutralization. When neutralized by alkaline agent, negative charges repel each other to stretch polymer chains, constructing 3D network structure to lock water molecules and generate high viscosity and gel strength.
This three-dimensional network can suspend solid particles uniformly, stabilize oil-water emulsions. When applied on skin, it forms lightweight hydrophilic film, improves product spreadability, delivers smooth gel texture. It does not penetrate skin, mainly optimizes formula rheology, texture and physical stability. Electrolytes and strong acid-base environment will destroy its network structure and lead to viscosity drop.

Formulation Guide: Dosage, Solubility & Matching Tips
Recommended dosage:
- -Transparent skincare gel: 0.2%-0.5%
- -Hair styling gel: 0.3%-0.8%
- -O/W lotion & gel-cream: 0.1%-0.3%
- -Particle-suspending formula: 0.25%-1.0%
Solubility: Water-swellable powder, insoluble in oil phase; must disperse and swell in water phase, effective thickening only after alkali neutralization.
Recommended matching ingredients: Triethanolamine, AMP-95, sodium hydroxide (neutralizer), glycerin, sorbitol, non-ionic emulsifier, xanthan gum (compound use for better salt-resistance).
Formulation Notes:
- -Slowly sprinkle Carbomer 940 powder into high-speed-stirred water phase, avoid pouring into static water directly to prevent hard lumping.
- -Complete swelling: keep stirring for 3-8 minutes, stand for 30-60 minutes to achieve full hydration before adding neutralizer.
- -Neutralize to target pH 6.0-7.5 to reach maximum viscosity; viscosity will drop sharply below pH5.0.
- -Avoid excessive high-shear stirring after neutralization, which will cause irreversible viscosity loss.
- -Minimize high-salt, high-electrolyte raw-materials in formula, electrolytes will reduce thickening performance of Carbomer 940. belonging to strong hygroscopic powder, seal tightly during storage to prevent moisture caking.
