International Chemical Investors Group

What International Chemical Investors Group does

International Chemical Investors Group (ICIG) is a privately owned industrial holding company headquartered in Luxembourg with its principal corporate entity ICI Holding SE registered in Frankfurt, Germany. Founded in 2004, ICIG acquires non-core chemical businesses — typically carve-outs from large multinational corporates such as Rütgers, Clariant, Albemarle, INEOS, Evonik, Valtris, BASF, and Venator — and develops them as independently operated, niche-leading specialty chemical companies. Since inception, the group has acquired more than 30 businesses and currently operates six market-oriented platforms: WeylChem (fine chemicals, custom manufacturing, and advanced intermediates for pharmaceutical, agrochemical, and polymer customers); Catexel (care chemicals including bleach activators, hydrotropes, and optical brighteners for home and personal care); Benvic (thermoplastic compounds based on PVC, engineering polymers, and bio-polymers); Haltermann Carless (hydrocarbon specialties, performance fuels, and transformer oil services with sales reach in more than 90 countries); Stockhausen (superabsorbent polymers and acrylic acid, formed in 2024 from Evonik's superabsorbents business); and Enterprises (specialized businesses including activated carbon, fermentation, wood protection, viscose filament yarn, pigments, and industrial drying services). ICIG also operates ICIG Ventures, a venture capital arm investing in industrial biotechnology, chemistry, and advanced materials startups.

ICIG's underlying technology is rooted in specialized chemical manufacturing and custom synthesis. WeylChem operates eight manufacturing facilities across Europe and India with capabilities in bromination, chlorination, C-C coupling, diazo chemistry, Friedel-Crafts alkylation and acylation, Grignard reactions, halogen exchange, hydrogenation, sulfuric acid production, and glyoxal/glyoxylic acid derivatives. Catexel is the world market leader for bleach activators and catalysis and the largest hydrotropes producer in the United States, with additional capacity in low-temperature chemistry, oxidation, TAED, sodium paraffin sulfonate, and optical brighteners. Benvic produces bio-based and compostable thermoplastic compounds, mission-critical medical compounds, halogen-free flame retardant compounds, and recycled solutions across seven manufacturing sites plus one recycling center in Europe and the US. Stockhausen operates four manufacturing sites producing FAVOR-brand superabsorbent polymers and acrylic acid. Corden BioChem operates microbial fermentation and bioethanol facilities, including a restarted plant in Podari, Romania.

ICIG generates revenue through the manufacture and sale of specialty chemicals, fine chemicals, care chemicals, hydrocarbon specialties, superabsorbents, thermoplastic compounds, and other chemical products to global industrial customers in pharmaceutical, agrochemical, polymer, consumer products, water treatment, hygiene, textile, and wood protection sectors. The group operates on a sales-led, B2B direct-distribution model, with each platform maintaining dedicated direct-sales organizations and platform-specific websites, serving enterprise customers across Europe, the United States, and Asia. Group-level revenue exceeds €2.8 billion annually across approximately 5,950 employees and more than 45 manufacturing plants, with no public equity listing and ownership retained by founding management.

Direct peers

• Lanxess AG: German specialty chemicals company with comparable end-market exposure in performance chemicals, advanced industrial intermediates and specialty additives across Europe, the US and Asia. Similar in scale (~€6-7B revenue) and in operating philosophy of running niche-leading specialty assets carved out or spun out of larger chemical groups.
• Altana AG: Privately held German specialty chemicals group focused on additives, coatings, electrical insulation and pigments. Closely comparable to ICIG in being a family/founder-controlled private industrial holding that runs specialty chemical businesses with leading niche positions.

Broad incumbents

• Evonik Industries AG: German specialty chemicals major (€15B+ revenue) from which ICIG has acquired multiple businesses (superabsorbents, Lulsdorf site). Overlaps with ICIG in specialty additives, superabsorbents and fine chemicals and serves as a key source of divestiture flow for ICIG.
• Clariant AG: Swiss specialty chemicals company focused on care chemicals, catalysts and natural resources. ICIG acquired Clariant's Custom Manufacturing business in 2007 and a Clariant bioethanol plant in 2024, with overlapping capabilities in care chemicals (vs. Catexel) and custom synthesis (vs. WeylChem).
• Arkema SA: French specialty materials group with €9-10B revenue across adhesives, advanced materials and coating solutions. Comparable to ICIG in European base, B2B specialty chemicals focus and downstream exposure to construction, automotive and consumer durables.
• Wacker Chemie AG: German specialty chemicals company with operations in silicones, polymers, biosolutions and polysilicon. Comparable to ICIG in being a European-headquartered, family-influenced specialty chemicals group with deep chemical engineering capabilities and global manufacturing.
• Solvay SA: Belgian chemicals group (split into Syensqo for specialty and Solvay for soda ash/chemicals). ICIG acquired Synkem from Solvay Pharma (2007) and INOVYN chlorovinyls (joint with INEOS, 2015) which became Vynova, making it both a counterparty and a key benchmark for specialty/soda ash valuations.
• INEOS Group: Privately held European chemicals conglomerate spanning petrochemicals, specialty chemicals and consumer products. Comparable to ICIG in private ownership, acquisition-driven growth and commodity-to-specialty portfolio, including joint INOVYN ownership that spun out Vynova to ICIG.
• Croda International plc: UK-listed specialty chemicals company focused on personal care, life sciences and performance technologies. Comparable to ICIG/Catexel in care chemicals, surfactants and consumer-adjacent specialty ingredients, and to WeylChem in supplying pharmaceutical and agrochemical customers.

Emerging players

• Element Solutions Inc. US-listed specialty chemicals platform built via serial acquisitions of niche electronics, industrial and automotive chemical businesses. Operates with a similar 'buy-and-operate niche leaders' playbook to ICIG, albeit in different end-markets (electronics assembly, automotive).
