Types segmentation distinguishes carbomer grades by molecular weight, cross‑link density, and functional side‑chain composition, most commonly classified as Carbomer 940, 934, 980, 981, and 994. Carbomer 940, a high‑molecular‑weight polymer with dense cross‑linking, provides the greatest viscosity increase per unit weight and dominates the liquid‑wash segment, contributing roughly 40 % of the total type‑based volume. Carbomer 934, slightly lower in molecular weight, offers a balance between thickening power and clarity, and is preferred in transparent shower gels, accounting for about 30 % of usage. Carbomer 980 and 981, characterized by moderate molecular weight and enhanced solubility, are employed in foam‑based cleansers where rapid hydration and low‑pH stability are required, together representing approximately 20 % of the market. Carbomer 994, a low‑viscosity grade, is used in specialty bar‑soap formulations to improve melt‑release and reduce brittleness, comprising the remaining 10 %. This type‑level taxonomy clarifies how each carbomer grade underpins distinct formulation performance criteria and collectively drives the overall market size.
