Carbomer 940, also commonly referred to as Carbopol, is a highly effective rheology modifier widely utilized in the personal care and cosmetics industries. Identified by CAS registry number 9003-01-4, it is chemically a synthetic high molecular weight polymer of acrylic acid, intricately crosslinked with polyfunctional compounds. This unique polymeric structure is responsible for its exceptional ability to thicken, suspend particles, and stabilize challenging formulations, making it a cornerstone ingredient for achieving desired textures and stability in various consumer products.

Presented as a fine, white, fluffy powder, Carbomer 940 exhibits a remarkable characteristic: upon dispersion in water and subsequent neutralization, it undergoes significant swelling. This process leads to the formation of highly viscous gels, even at very low concentrations. The resulting gels are typically characterized by their clarity and smooth texture, properties that are highly valued in aesthetic-focused applications. The efficiency of Carbomer 940 in viscosity building and stabilization is strongly influenced by pH, performing optimally in slightly acidic to alkaline conditions, usually between pH 5.0 and 10.0.

The applications of Carbomer 940 are diverse and span across numerous personal care product categories. It is a critical component in formulating clear hand sanitizers, where it provides the necessary gel consistency without impairing transparency. In skin care products such as lotions, creams, and serums, it enhances body, aids in suspending active ingredients evenly throughout the product, and improves the feel and spreadability on the skin. Hair styling gels rely on Carbomer 940 for its strong gelling properties that provide hold and structure. Furthermore, it finds use in shampoos and body washes to control viscosity, suspend solid particles like exfoliants or beads, and ensure a stable, appealing product presentation.

Maintaining rigorous quality control is paramount for Carbomer 940 to ensure consistent performance in final formulations. Standard quality specifications include measuring the viscosity of aqueous solutions at defined concentrations, assessing solution clarity, and testing for purity markers such as residual acrylic acid monomer and heavy metals. The various numerical designations of Carbomers (e.g., 910, 934, 940, 941) primarily denote differences in molecular weight, degree of crosslinking, and the specific solvent used during polymerization. These variations impact the rheological profile, with Carbomer 940 being particularly suitable for applications requiring high viscosity and excellent suspending capabilities, especially in clear gel systems.
