Essential Commodity Chemicals

June 18, 2025

Supporting Industry with Consistency, Quality and Expertise

At Biocel, we recognise the crucial role that commodity chemicals play in everyday operations across various industries. Whether you’re managing hygiene in a dairy plant, ensuring compliance in pharmaceutical manufacturing, or maintaining clean water systems, these core chemicals are the building blocks of safe, efficient production.

We supply a carefully selected range of high-purity commodity chemicals, including caustic soda, nitric acid, hydrochloric acid, phosphoric acid, sodium hypochlorite, and hydrogen peroxide, each backed by Biocel’s commitment to quality, traceability, and expert support.

Meeting Industry Needs with Trusted Chemical Solutions

Let’s take a closer look at the commodity chemicals we supply and why they matter to the industries we serve.

1. Sodium Hydroxide (Caustic Soda)

A mainstay in CIP (clean-in-place) cleaning, sodium hydroxide is essential for breaking down organic soils in dairy, food, and beverage processing. It’s also widely used in pH correction and water treatment. We supply caustic soda in varying strengths to suit your process, and back it up with safety and handling guidance.

2. Potassium Hydroxide (KOH)

Potassium hydroxide offers similar alkalinity to caustic soda but with greater solubility and less salt formation, making it the preferred choice in applications where residue control is critical, such as pharma, cosmetics, and specialist cleaning formulations. It’s particularly valued in environments where sodium-free solutions are preferred.

3. Nitric Acid (HNO₃)

Used across the pharmaceutical, brewing, and medical device industries, nitric acid plays a key role in descaling and passivating stainless steel. We supply it in strengths ideal for equipment sanitisation, helping maintain hygiene and prolong equipment life without aggressive wear.

4. Hydrochloric Acid

Hydrochloric acid (HCL) remains a cost-effective solution for removing lime scale and iron deposits, especially in boiler systems, pipework, and heat exchangers. We support customers in industrial cleaning, water treatment, and engineering with a safe, compliant supply of this powerful mineral acid.

5. Phosphoric Acid (H₃PO₄)

A favourite in the dairy and brewing industries, phosphoric acid removes scale without damaging stainless steel, making it ideal for food-contact environments. It’s also widely used for pH control in both process and finished products. Our food-grade phosphoric acid is compliant, consistent, and dependable.

6. Sodium Hypochlorite

Sodium hypochlorite (NaClO) delivers broad-spectrum disinfection and is essential in Cleaning-in-Place (CIP) rinses, equipment sanitation, and water purification. We supply stable, high-quality hypochlorite solutions trusted by food processors, dairies, and municipal water authorities across Ireland.

7. Hydrogen Peroxide

For applications that demand chlorine-free disinfection, hydrogen peroxide is an excellent choice. It’s effective, biodegradable, and leaves no harmful residues. From cleanroom sterilisation to odour control, we help customers integrate it safely into their cleaning protocols with technical support at every stage.

At A Glance: Which Commodity Chemical is Best for Your Industry?

  • Sodium Hydroxide (Caustic Soda) – A strong base, ideal for removing organic buildup in CIP systems and dairy lines.
  • Potassium Hydroxide – Effective in soft water areas; strong cleaning base used in pharma and cosmetics.
  • Nitric Acid – Strong acid used for descaling and passivation, particularly in dairy and food plants.
  • Hydrochloric Acid – A rapid descaler for mineral build-up, effective in heavy-duty cleaning applications.
  • Phosphoric Acid – Food-safe acid for scale removal and pH adjustment.
  • Sodium Hypochlorite – Widely used disinfectant; effective but may leave residues.
  • Hydrogen Peroxide – A chlorine-free disinfectant that breaks down into water and oxygen, making it ideal for use in the pharmaceutical and food industries.

Compare Cleaning Power, Residue Impact & Material Suitability

This comparison chart outlines the key commodity chemicals supplied by Biocel, focusing on three critical factors for industry buyers: cleaning power, residue impact, and material suitability. Each chemical is colour-coded by function, acid, base, or disinfectant, to help quickly identify its primary role. The chart is designed to support informed decision-making across various sectors, including food and beverage, pharmaceutical, dairy, and water treatment, offering practical insights into performance, compatibility with equipment, and residue behaviour after application.

Chemical Primary Industries Key Functions Best For Residue / Handling Notes
Sodium Hydroxide (NaOH) Dairy, Food & Beverage, Water Treatment Alkaline cleaning (CIP), pH adjustment Breaking down organic soils (fats, proteins) Leaves sodium salts, requires thorough rinsing
Potassium Hydroxide (KOH) Pharma, Cosmetics, Specialist Cleaning High-pH cleaning, pH regulation Sodium-free cleaning, sensitive formulations More soluble, fewer residues than NaOH
Nitric Acid (HNO₃) Pharma, Brewing, Medical Devices Descaling, stainless steel passivation Acid CIP, preventing corrosion Handle with care; fumes require good ventilation
Hydrochloric Acid (HCl) Industrial Cleaning, Water Treatment Limescale and iron deposit removal Descaling boilers, tanks, and pipework Aggressive; incompatible with some metals
Phosphoric Acid (H₃PO₄) Dairy, Brewing, Food & Beverage Mild descaling, pH correction Food-safe acid cleaning, calcium scale removal Non-aggressive, food-contact safe
Sodium Hypochlorite (NaOCl) Dairy, Food & Beverage, Water Treatment Oxidation, sterilisation, and biofilm removal Surface sanitisation, CIP rinse, water disinfection Disinfection, sanitation, and chlorination
Hydrogen Peroxide (H₂O₂) Pharma, Cleanrooms, Odour Control Oxidation, sterilisation, biofilm removal Chlorine-free disinfection, cold sterilisation Breaks down into water & oxygen, no residue

Industry-Specific Applications

For Food & Beverage Plants

Our food-grade commodity chemicals ensure safe, effective sanitation while protecting product integrity:

  • Choose Phosphoric Acid or Hydrogen Peroxide for food-safe sanitation. Phosphoric Acid is ideal for scale removal and food-safe pH adjustment in beverage and bottling plants. Hydrogen Peroxide disinfectant is a powerful, chlorine-free sanitation solution that leaves no harmful residues, perfect for food processing disinfection.
  • Use Sodium Hydroxide for highly effective organic residue removal, pipeline cleaning, and CIP (Clean-in-Place) systems.

For Dairy Processing

Dairy plants face unique sanitation challenges due to the combination of proteins, fats, and minerals:

  • Use Nitric Acid for descaling pasteurisers, evaporators, and pipelines, preventing costly downtime.
  • Sodium Hydroxide (Caustic Soda) breaks down protein residues to ensure hygienic equipment surfaces and prevent bacterial contamination.
  • Phosphoric Acid offers gentle pH control with no aggressive odours.

For Pharma & Cleanrooms

Sterility and purity are non-negotiable in pharmaceutical manufacturing and cleanroom operations. Our high-purity commodity chemicals meet the strictest standards:

  • Opt for Hydrogen Peroxide to maintain sterile environments, surface decontamination, and equipment disinfection without chlorine residues.
  • Potassium Hydroxide is commonly used in the production of personal care products, cosmetics, and certain pharmaceutical formulations. It’s controlled alkalinity supports consistent product quality and precise pH control.

For Water Treatment

Effective chemical treatment ensures safe, clean water across public water services, industrial processes, and commercial facilities:

  • Sodium Hypochlorite provides reliable disinfection for public water supply systems and wastewater treatment.
  • Hydrochloric Acid controls scale buildup in pipelines, boilers, and water treatment equipment, helping maintain system efficiency.

Frequently Asked Questions (FAQs)

What is the safest disinfectant for food production?

Hydrogen Peroxide is often the best choice as it’s chlorine-free and leaves no residues, ideal for food-contact surfaces.

Is Sodium Hypochlorite suitable for stainless steel?

It should be used cautiously. Long-term exposure or improper dilution can cause stainless steel to corrode.

Can I use Phosphoric Acid in CIP systems?

Yes, it is widely used for pH adjustment and scale removal, particularly effective in breweries for eliminating beerstone and in dairy operations for removing milkstone deposits. 

What’s the difference between Sodium Hydroxide and Potassium Hydroxide?

Both are strong bases, but KOH is more soluble and less aggressive, making it suitable for cosmetic and pharmaceutical use.
