Carbomer (CAS 9003-01-4 / 9007-20-9 / 25035-69-2 / 76050-42-5)
is a high-molecular-weight cross-linked acrylic polymer. It appears as a white loose powder with excellent thickening, suspending, emulsifying and stabilizing properties.
As a globally recognized high-efficiency rheology modifier, Carbomer can form transparent gels or thickened systems at a low dosage of 0.1%–1.0%.
It is widely used in skin care products (serums, creams, gels), personal care products (shampoos, body washes), pharmaceutical applications (topical gels, ophthalmic preparations) and various industrial fields.
As a professional source manufacturer, we supply a full range of Carbomer grades including Carbomer 934, 940, 941, 980 and more, with stable bulk supply capacity for global customers.
Core Advantages
1. Excellent Thickening Efficiency
High Efficiency at Low Dosage: A dosage of only 0.1%–1.0% delivers outstanding thickening performance.
High Clarity: Forms crystal-clear gels after neutralization, ideal for transparent formulations.
Excellent Skin Feel: Offers a wide range of textures from light and refreshing to rich and moisturizing.
2. Outstanding Rheological Properties
Pseudoplasticity: Shear-thinning behavior ensures easy application, with viscosity rapidly restored after spreading.
Suspension & Stability: Effectively suspends particles, bubbles and insoluble ingredients to prevent sedimentation.
3. Strong Formulation Compatibility
Flexible Neutralization: Can be neutralized with triethanolamine (TEA), sodium hydroxide, potassium hydroxide and other agents.
Good Compatibility: Compatible with most surfactants, humectants and oils.
