Carbomer 941 is a synthetic, crosslinked polyacrylic acid polymer used in cosmetic and personal-care formulations as a thickener, rheology modifier, suspending agent and emulsion stabilizer. Carbomer polymers are high-molecular-weight crosslinked acrylic polymers that can develop viscosity when dispersed in water and appropriately neutralized.
Carbomer 941 is particularly useful when a formulation requires controlled viscosity with a smooth, structured consistency. It can help modify the flow behavior of creams, lotions, gels and other aqueous or emulsion-based cosmetic systems.
Carbomer 941 is supplied as a white, fluffy powder with a slightly acetic odor. The polymer swells when properly dispersed and can form a three-dimensional network after neutralization. This network increases viscosity and can contribute to suspension and formulation stability.
For Carbopol® 941 NF polymer, Lubrizol specifies a viscosity range of 4,000–10,000 cP at 25°C for a 0.5% w/w mucilage neutralized to pH 7.3–7.8. The same specification lists a carboxylic acid content of 56.0–68.0% and loss on drying of NMT 2.0%.
Carbomer 941 provides viscosity enhancement in suitable aqueous formulations. After hydration and appropriate neutralization, the polymer expands and forms a structured network that increases the viscosity of the formulation.
Carbomer 941 helps control formulation flow and consistency. Its rheological properties make it useful when formulators require a stable, structured texture in creams, lotions and gel-based products.
The viscosity and yield characteristics developed by Carbomer 941 can help maintain suitable dispersed ingredients throughout a formulation. This makes it useful in selected suspension systems.
Carbomer polymers are used for emulsion stabilization and rheological control. Increasing the viscosity of the continuous phase can help reduce movement of dispersed components and support physical stability in suitable formulations.
Carbomer 941 can be used in creams, lotions, moisturizers, gels and other skin-care formulations where viscosity, texture and physical stability are important.
After proper dispersion, hydration and neutralization, Carbomer 941 can create structured aqueous gel systems. Final viscosity and appearance depend on concentration, neutralization, pH and the other ingredients in the formulation.
Carbomer 941 can be incorporated into suitable hair-care and personal-care formulations where thickening, suspension and rheology modification are required.
Carbomer 941 should be dispersed uniformly to minimize lump formation and allow proper hydration. Neutralization has a major effect on viscosity development.
Formulation factors such as pH, polymer concentration, electrolytes, surfactants, salts and solvents can influence the final rheological properties. The exact processing procedure should therefore be established according to the selected commercial grade.
For Carbopol® 941 NF, the viscosity specification is measured after neutralization to pH 7.3–7.8 using a defined Brookfield RVT method. The numerical viscosity specification should not be transferred to unrelated Carbomer 941 grades without confirming their technical documentation.
Carbomer 941 can be used in:
Carbomer 941 is a synthetic crosslinked polyacrylic acid polymer used primarily as a thickener, rheology modifier, suspending agent and stabilizer in cosmetic formulations.
CAS Number: 9003-01-4 is associated with poly(acrylic acid)/acrylic acid polymer records, while PubChem also maintains a distinct Carbomer 941 record with the synonym 9062-04-8. The CAS identifier should therefore be matched to the exact material and supplier documentation before publishing it as the definitive product CAS number.
