Processing Methods & Reference Formulations
A. Cosmetic cream
In cream production, sprinkle Carbomer into the aqueous phase with gentle stirring to avoid clumping, then allow full hydration. Use at 0.1–1%, depending on the desired consistency and feel. Neutralization should be done gradually to reach a pH of 5.5–7 for optimal viscosity
| Key Ingredients | Indicative Dosage (% w/w) |
|---|---|
| Water (Purified) | 66.75% |
| Propylene Glycol | 3.71% |
| Isopropyl Palmitate | 0.93% |
| White Oleic Acid | 1.16% |
| Sorbitan Stearate | 0.74% |
| Cetyl Alcohol | 0.46% |
| Stearyl Alcohol | 0.46% |
| Synthetic Beeswax | 0.46% |
| Glyceryl Monostearate | 1.16% |
| Stearic Acid | 1.16% |
| Polysorbate 61 (Sorbitan Stearate) | 1.16% |
| Myristyl Myristate | 1.39% |
| Methylparaben | 0.15% |
| Propylparaben | 0.10% |
| Butylparaben | 0.05% |
| Butylated HydroxyToluene | 0.02% |
| Sodium Hydroxide | 0.12% |
| Titanium Dioxide | 0.20% |
| Benzyl Alcohol | 0.28% |
| Fragrance | 0.20% |
| Carbomer 941 | 0.28% |
B. Hair shampoo
In hair shampoo production, disperse Carbomer slowly into the aqueous phase under continuous stirring to prevent clumping. Add surfactants after neutralization to avoid viscosity loss. Use at 0.1–1% for clear, stable, and smooth-flowing shampoos.
| Key Ingredients | Indicative Dosage (% w/w) |
|---|---|
| Primary surfactants | 8-12% |
| Secondary surfactants | 2-5% |
| Butters | 20-40% |
| Carbomer | 0.1-1% |
| Water | 40-50% |
C. Sunscreen lotion
Disperse carbomer slowly into the water phase under vigorous stirring to prevent clumping, then neutralize with a suitable base to activate gelling. Maintain pH around 6–7 to preserve both Carbomer and UV filters. Use at 0.1–0.5%, and add after emulsification if fine viscosity adjustment is needed.
| Key Ingredients | Indicative Dosage (% w/w) |
|---|---|
| Avobenzone | 3% |
| Octocrylene | 7% |
| C12-15 Alkyl Benzoate | 5% |
| Glyceryl Stearate / PEG-100 Stearate | 4.5% |
| Water | 60-70% |
| Glycerine | 4% |
| Carbomer | 0.2% |
D. Liquid Foundation
Disperse Carbomer slowly into the water phase with gentle stirring to avoid clumps. Neutralize it with a suitable base (like triethanolamine) after full hydration to achieve desired gel viscosity and smooth texture in the foundation.
| Key Ingredients | Indicative Dosage (% w/w) |
|---|---|
| Dimethicone | 10% |
| Glycerin | 5% |
| Titanium Dioxide | 3% |
| Phenoxyethanol | 0.8% |
| Triethanolamine | 0.3% |
| Carbomer | 0.5% |
| Water | 70-80% |

| Skin Creams, Gels | 0.5-1% |
| Skin Lotions, Hydrating Lotions | 0.2-0.75% |
| Skin Serums | >0.5% |
| Hair products | 0.5-1% |
About Carbomer 940
Carbomer 940 is a versatile, high-molecular-weight polymer widely recognized for its exceptional ability to create clear, viscous gels and stable emulsions. It’s valued for its consistency and purity, sourced from top Carbomer 940 manufacturers who prioritize quality at every stage of the production process.
One of Carbomer 940’s standout qualities is its superior thickening and gelling properties. When added to water, it swells to form a smooth, highly viscous gel, providing excellent stability in formulations. This ability to create thick, transparent gels makes Carbomer 940 a go-to polymer in various demanding settings.
What truly sets this polymer apart is its efficiency at low concentrations. A small amount of Carbomer 940 is enough to achieve significant viscosity and stability. Its impressive yield value ensures that even minimal usage delivers a powerful effect, reducing material costs while maintaining high performance.
Carbomer 940 also excels in suspending and stabilizing ingredients. Thanks to its crosslinked structure, it provides excellent rheological control, ensuring uniformity and consistency in formulations. It prevents ingredient separation and helps maintain product integrity, offering long-lasting stability even in challenging environments.
Its electrolyte tolerance is another important feature. Carbomer 940 can withstand the presence of salts and other ionic components without compromising its gelling and thickening abilities, ensuring that it remains effective in a wide range of formulations.
This polymer is also noted for its clarity and purity. When properly neutralized, it forms crystal-clear gels that enhance the aesthetics of any formulation, making it ideal for those who require both functionality and visual appeal in their products.
Produced under stringent standards, our Carbomer 940 offers consistency and reliability, backed by trusted carbomer 940 manufacturers.
