Introduction to Sulphuric Acid in the Cleaning Chemicals Industry

Sulphuric acid (H₂SO₄) is one of the most important industrial chemicals in the world, often referred to as the "king of chemicals" due to its extensive use in manufacturing and chemical processing. In the soap and cleaning chemicals industry, it serves as a critical raw material and catalyst in producing surfactants, detergents, and other cleansing agents.

The global cleaning chemicals industry relies heavily on sulphuric acid for both direct and indirect applications. It is essential in the sulfation and sulfonation processes that transform fatty alcohols into surfactants, key active ingredients responsible for cleaning and foaming properties.

Singapore, being a global hub for chemical trade and logistics, plays an influential role in connecting manufacturers, distributors, and end-users of sulphuric acid. The nation’s advanced port infrastructure and strategic location make it a vital distribution center for Southeast Asia and the wider Asia-Pacific region.
 

Chemical Composition and Role in Soap Manufacturing

Sulphuric acid is a strong mineral acid known for its high reactivity and dehydration properties. It is typically manufactured via the Contact Process, where sulfur dioxide is oxidized to sulfur trioxide and then absorbed in water. The resulting product can vary in concentration, with commercial grades ranging from 93% to 98%.

In the soap and detergent sector, sulphuric acid is primarily used to produce linear alkylbenzene sulfonic acid (LABSA) one of the most common surfactants. LABSA is derived through sulfonation of linear alkylbenzene (LAB) using sulphuric acid or oleum, forming the basis of household detergents and industrial cleaners.

Beyond surfactant synthesis, sulphuric acid is also used to adjust pH levels, neutralize alkaline substances, and refine feedstocks used in detergent manufacturing. Its ability to catalyze reactions and remove impurities ensures high-quality output in both solid and liquid cleaning formulations.
 

Key Growth Drivers for Sulphuric Acid Demand

The demand for sulphuric acid in the cleaning and soap industry is driven by several key factors, including urbanization, industrial growth, and rising hygiene awareness. With the global population increasingly concentrated in urban areas, consumption of detergents and household cleaning products continues to climb.

In addition, the post-pandemic period has seen heightened attention toward sanitation and hygiene, resulting in increased production of soaps, disinfectants, and cleaning chemicals. This has amplified the demand for sulphuric acid-based intermediates used in surfactant and detergent formulations.

Emerging economies in Asia-Pacific and Africa are expanding manufacturing capabilities for cleaning products, creating sustained demand for sulphuric acid imports. Singapore, with its robust infrastructure and chemical expertise, remains a key supplier and re-exporter to these growing markets.
 

Industrial Applications in Detergent and Cleaning Formulations

In industrial detergent manufacturing, sulphuric acid is integral to several production stages. It acts as a sulfonating and sulfating agent, converting fatty alcohols and hydrocarbons into active surfactant compounds. These surfactants provide the essential cleaning power found in laundry powders, dishwashing liquids, and industrial degreasers.

Sulphuric acid is also employed in the formulation of specialty cleaning agents, such as metal cleaners and acid-based bathroom products. Its ability to dissolve scale, rust, and mineral deposits makes it valuable in institutional and industrial cleaning sectors.

Additionally, sulphuric acid supports the production of other chemical intermediates used in detergents, including sodium lauryl sulfate (SLS) and ammonium lauryl sulfate (ALS). These materials form the core of high-foaming formulations, enhancing both cleaning efficacy and user satisfaction.
 

Market Insights and Demand Forecast (2025 - 2030)

The global sulphuric acid market is projected to maintain steady growth between 2025 and 2030, supported by expanding applications in cleaning chemicals and related industries. According to Mordor Intelligence and IMARC Group, the market is expected to grow at a CAGR of 3.8-4.5%, reaching over USD 15 billion by 2030.

The Asia-Pacific region continues to dominate both production and consumption, with China, India, and Singapore serving as central hubs. These countries are investing in chemical clusters and integrated refinery-petrochemical complexes that support large-scale acid production and downstream detergent manufacturing.

For Singapore specifically, the growing regional demand for hygiene and cleaning solutions provides new opportunities for trade and value-added distribution. Local chemical companies are expanding their service portfolios to include bulk acid handling, customized blending, and just-in-time delivery systems for clients across Asia.
 

Singapore’s Role as a Global Chemical Trade Hub

Singapore’s geographical advantage and business-friendly ecosystem make it a strategic center for sulphuric acid distribution. The nation imports and re-exports significant quantities of industrial acids to countries such as Indonesia, Malaysia, Vietnam, and the Philippines.

With major storage terminals located in Jurong Island, Singapore’s infrastructure supports bulk handling of hazardous chemicals with advanced safety and environmental control measures. These facilities enable efficient consolidation and redistribution of sulphuric acid products to manufacturers in the cleaning and detergent sectors.

Furthermore, Singapore’s chemical industry cluster, supported by the Economic Development Board (EDB), fosters partnerships between global chemical producers and logistics providers. This collaborative environment ensures a consistent, high-quality supply chain for critical inputs like sulphuric acid, contributing to regional industrial growth.
 

Technological Advancements and Process Innovations

Technological innovation in sulphuric acid manufacturing has focused on energy efficiency and emissions reduction. Modern plants utilize double absorption contact processes that improve conversion rates while minimizing sulfur dioxide emissions, a key environmental concern.

Emerging technologies such as heat recovery systems allow manufacturers to capture and reuse waste heat from acid production, improving sustainability and reducing operational costs. This is particularly relevant for Singapore’s industries, which prioritize eco-efficiency and circular economy practices.

Additionally, process automation and digital monitoring are transforming chemical manufacturing. Advanced sensors and AI-driven predictive systems now optimize reaction parameters, ensuring consistent acid concentration and purity levels suited for detergent-grade applications.
 

Sustainability and Environmental Management in Sulphuric Acid Production

As environmental regulations tighten globally, the sulphuric acid industry is embracing sustainable practices across its value chain. Producers are investing in cleaner technologies and closed-loop systems that minimize waste and recover by-products such as sulfur dioxide for reuse.

In Singapore, the National Environment Agency (NEA) enforces strict standards for emissions, waste management, and chemical handling. Companies operating within Jurong Island adhere to international certifications such as ISO 14001 and OHSAS 18001, ensuring compliance with environmental and occupational safety protocols.

Sustainability also extends to the downstream detergent industry. Manufacturers are adopting eco-labeling and biodegradable surfactant initiatives, promoting environmentally responsible cleaning products. The use of high-purity sulphuric acid supports these goals by reducing impurities and improving process efficiency.
 

Competitive Landscape and Key Players

The global sulphuric acid market is characterized by a mix of large multinational producers and regional suppliers. Major players include:

In Singapore and Southeast Asia, several trading and logistics companies play a vital role in the regional supply network. These firms specialize in bulk chemical transportation, tank storage, and distribution services, ensuring steady supply to detergent and cleaning chemical manufacturers.
