Introduction

Caustic soda liquid, or sodium hydroxide solution (NaOH), is a core industrial chemical used across a wide range of sectors. In its liquid form, it offers advantages in handling, mixing, and logistics, making it highly preferred for continuous and automated processes. Its high reactivity and solubility make it a go-to substance for various chemical applications.

Globally, the demand for caustic soda liquid continues to rise due to its critical role in manufacturing, water treatment, and food processing. According to Grand View Research, the global caustic soda market is projected to see substantial growth by 2030 due to increased industrial demand, particularly from Asia-Pacific regions.

In Indonesia, industries rely heavily on this chemical for large-scale applications. As industrial automation grows, using liquid caustic soda is becoming easier for engineers and production managers. They prefer it over flakes or pearls.

Chemtradeasia is a trusted supplier of high-quality liquid caustic soda in Indonesia. They provide a steady supply and technical support to industries that need reliable chemical sourcing. Our extensive distribution network ensures timely and secure delivery for your production needs.

 

What is Caustic Soda Liquid?

Caustic soda liquid is a water-based solution of sodium hydroxide (NaOH), typically found in concentrations ranging from 30% to 50%. It is a powerful base and alkaline compound, making it essential for pH control, neutralization reactions, and cleaning operations in industrial settings.

Due to its strong caustic nature, the solution is effective in dissolving organic and inorganic substances such as fats, oils, proteins, and metal ions. This property allows it to be used in various chemical synthesis and cleaning processes, improving both productivity and hygiene standards.

As reported by PubChem under the U.S. National Institutes of Health (NIH), sodium hydroxide is highly soluble in water and produces an exothermic reaction, releasing heat during dilution. This reaction must be carefully managed during industrial use.

Its versatility as a reactive agent allows it to be used not only in chemical manufacturing but also in industries like textiles, glass production, and even energy where it is involved in battery and biodiesel manufacturing processes.

 

Applications in the Chemical Industry

The chemical industry is one of the largest consumers of caustic soda liquid. It is used in saponification reactions to produce soaps and detergents, where it breaks down triglycerides into fatty acids and glycerol. This process forms the base of both personal care and industrial cleaning product lines.

Additionally, it plays a vital role in the paper and pulp industry, particularly in the Kraft process, where it helps separate lignin from cellulose fibers. Caustic soda also contributes to neutralizing acids and removing heavy metals from wastewater during treatment.

In the petroleum industry, sodium hydroxide is used to purify crude oil, neutralize acidic components, and in catalyst regeneration processes. It is also a key ingredient in the production of various chemicals such as sodium hypochlorite, which is widely used for disinfection.

According to ChemicalSafetyFacts.org, caustic soda is recognized as one of the most important inorganic chemicals used in commercial and industrial processing due to its high reactivity and cost efficiency.

 

Its Role in the Food Industry

In food production, caustic soda liquid is used for washing, peeling, and processing fruits and vegetables such as tomatoes and potatoes. The chemical helps loosen skins efficiently without damaging the flesh, saving time and improving output in food manufacturing.

It is also used in food-grade applications like adjusting acidity (pH), processing cocoa and chocolate, and making caramel coloring. In pretzel baking, for example, the dough is briefly dipped in a caustic soda solution to create the distinctive brown crust and flavor.

Regulatory bodies such as the Food Chemicals Codex and Codex Alimentarius allow the use of sodium hydroxide in food, provided it meets purity standards and is applied within safe concentration limits.

In Indonesia, the National Agency of Drug and Food Control (BPOM) oversees food additives, ensuring that caustic soda used in processing complies with food safety regulations. Chemtradeasia supplies food-grade sodium hydroxide to meet these critical standards.
