  • Effective Thickening Agent: Carbomer 940 is highly effective at thickening aqueous solutions, creating a gel-like consistency. This property is especially useful in products like gels, creams, and lotions, where a consistent texture is desired.
  • Stability: Carbomer 940 helps stabilize emulsions and suspensions, preventing the separation of ingredients over time. This stability contributes to the overall quality and shelf life of products.
  • Versatility: It is compatible with a wide range of cosmetic and pharmaceutical ingredients, making it versatile for use in various formulations.
  • Clarity: Carbomer 940 can create clear formulations, which is important for products like gels and serums where transparency is desired.
  • Ease of Use: It is relatively easy to incorporate into formulations and can be dispersed in water with proper mixing techniques.


  • PH Sensitivity: Carbomer 940 is sensitive to pH levels. Its thickening and gelling properties can be affected by the PH of the formulation. Adjustments to pH might be required to achieve the desired consistency.
  • Neutralization Requirement: To fully activate and thicken Carbomer 940, neutralizing agents like sodium hydroxide or triethanolamine are often required. This can complicate the formulation process and necessitate careful pH adjustment.
  • High Viscosity: While its thickening ability is an advantage, Carbomer 940 can create very high viscosity in formulations. This might not be suitable for all types of products or preferred textures.
  • Potential Sensitivity: Some individuals might be sensitive or allergic to Carbomer 940, although adverse reactions are relatively rare.
  • Clumping and Dispersion Challenges: Carbomer 940 can form clumps when initially added to water, requiring thorough mixing and dispersion to achieve a homogenous solution.
  • Environmental Concerns: Like many synthetic polymers, there can be environmental concerns related to the production, usage, and disposal of Carbomer 940-containing products.
