Carbopol / Cross-linked Polyacrylic Acid

Specialty chemicals; near-monopoly on Carbopol cross-linked polyacrylic acid gelling agents.

German specialty chemicals company; major producer of methyl mercaptan (used in methionine synthesis for animal feed) and other organosulfur chemicals. Also produces specialty sulfur chemicals including mercaptan blends used in gas odorization. Evonik's organosulfur chemicals are primarily focused on methionine production (world's largest DL-methionine producer under 'EVONIK MetAMINO' brand) — methionine is the most important amino acid supplement for poultry and aquaculture. Same mercaptan chemistry used in safety odorants also underpins the global animal feed amino acid supply chain.

Sumitomo Seika Chemicals Co., Ltd. (Osaka, Japan; TSE: 4008; Sumitomo Chemical Group subsidiary; ~¥180B revenue) produces carbomer-equivalent polyacrylic acid (PAA) polymers primarily for Japanese and Asian markets under its specialty polymer business. Sumitomo Seika's PAA polymers serve personal care and industrial thickening applications as alternatives to Lubrizol Carbopol within Japan and Asia. Sumitomo Seika is also Japan's second-largest superabsorbent polymer (SAP) producer under the AQUA KEEP brand for diaper applications, and produces hydrogen for fuel cells as a separate specialty gas business. Sumitomo Seika's carbomer market share outside Japan is limited.

SNF Group (Andrezieux-Boutheon, Loire, France; private; Chairperson Evelyne Spiegel; ~€4B revenue) is the world's largest polyacrylamide and polyacrylate polymer producer — dominant in water treatment, oil and gas enhanced recovery, and mining flocculant applications. SNF produces carbomer-equivalent polyacrylate polymers in its specialty polymer portfolio for personal care and pharmaceutical applications. SNF operates more than 30 manufacturing sites globally including plants in France (Andrezieux-Boutheon headquarters plant), USA (Riceboro GA), China, and India. SNF's polyacrylate capacity is primarily focused on industrial (water treatment, EOR) grades rather than pharmaceutical-grade carbomers — but the company's scale means it has production capacity that could be adapted. Market share in pharmaceutical-grade carbomers is much smaller than Lubrizol.

Zhejiang Haijia Chemical Technology Co., Ltd. (Jiaxing City, Zhejiang Province, China) is one of several Chinese chemical companies that entered the carbomer/polyacrylic acid market following COVID-19 demand signals in 2020-2021. Chinese manufacturers of carbomer-equivalent products — including Haijia Chemical, Guangzhou Tinci Materials Technology (listed; key lithium battery electrolyte and carbomer producer), and others — rapidly scaled capacity to capitalize on global shortages caused by Lubrizol allocation. These Chinese carbomers are primarily sold to Chinese domestic cosmetic, sanitizer, and pharmaceutical formulators; some export to Asian markets. Quality and rheological performance relative to Lubrizol Carbopol grades varies and is contested — Lubrizol's pharmaceutical grade Carbopol carries NF (National Formulary) certification that Chinese equivalents generally lack for regulated pharmaceutical applications.
