Start Sodium Hypochlorite Manufacturing Business

Categories

The Sodium Hypochlorite Manufacturing Business is emerging as a highly relevant and profitable venture, especially in today’s hygiene-conscious world. Sodium hypochlorite (NaOCl) is a clear, pale greenish-yellow liquid commonly used as a disinfectant, bleaching agent, and water treatment chemical. From hospitals and households to municipalities and industrial plants, sodium hypochlorite plays a crucial role in sanitation and disinfection. The COVID-19 pandemic further pushed the demand for surface sanitizers and disinfectant sprays, where sodium hypochlorite became a staple ingredient.

According to market estimates, the global sodium hypochlorite market is expected to grow at a CAGR of around 5.2%, reaching USD 350 million by 2030. In India, with government-driven sanitation missions like Swachh Bharat Abhiyan and increased focus on wastewater treatment and hygiene, the domestic demand is also rising steadily. The Sodium Hypochlorite Manufacturing Business is not only scalable but also relatively low-cost to set up, making it an ideal choice for entrepreneurs looking to enter the chemical manufacturing sector with high utility value and consistent market demand.

Why Start a Sodium Hypochlorite Manufacturing Business?

Starting a Sodium Hypochlorite Manufacturing Business offers multiple advantages. First, the product has a wide range of applications across industries such as water purification, food processing, textile bleaching, dairy equipment sanitization, and household cleaners. Second, the raw materials—mainly chlorine gas and caustic soda—are readily available in India. Third, the production process is technically simple and requires moderate capital investment. Finally, sodium hypochlorite has a high turnover rate due to its short shelf life, which ensures repeat demand from B2B clients, institutions, and sanitation services.

Moreover, sodium hypochlorite is a key component in municipal water treatment plants, swimming pools, and sewage systems, making it indispensable for public utilities. As urbanization increases and hygiene standards rise, the relevance of sodium hypochlorite will only grow further.

Raw Materials Required

To manufacture sodium hypochlorite, the following raw materials are needed:

Chlorine Gas (Cl?) – The primary input
Caustic Soda (NaOH) – Liquid form preferred
Soft Water – For dilution and reaction
Cooling Water – To control exothermic reactions
Stabilizers – Like sodium carbonate to increase shelf life

Most raw materials are easily sourced from domestic chemical suppliers or through bulk procurement agreements.

Manufacturing Process of Sodium Hypochlorite

The Sodium Hypochlorite Manufacturing Business follows a straightforward chemical reaction process:

Reaction:
$Cl2+2NaOH?NaCl+NaOCl+H2OCl_2 + 2NaOH \rightarrow NaCl + NaOCl + H_2O$

Step-by-Step Process:

Chlorination: Chlorine gas is introduced into a solution of caustic soda under controlled conditions.
Reaction Control: The temperature is maintained at 20–25°C using cooling systems to avoid chlorine loss.
Filtration: The resulting sodium hypochlorite solution is filtered to remove impurities.
Stabilization: Stabilizers are added to maintain chemical stability and shelf life.
Storage and Packaging: The final solution (usually 5–12% NaOCl) is stored in HDPE tanks and filled into plastic drums, bottles, or tanker trucks for delivery.

This process does not involve complex machinery, making the Sodium Hypochlorite Manufacturing Business accessible even for first-time chemical manufacturers.

Machinery and Equipment Needed

To set up a sodium hypochlorite manufacturing unit, the following machinery and equipment are required:

Chlorine gas handling system (including scrubber)
Caustic soda storage tank
Reaction vessels (SS316 or lined MS)
Cooling system (chiller or heat exchanger)
Agitators and mixers
Filtration unit
HDPE or PVC storage tanks
Drum filling and sealing machine
Lab testing equipment for pH, chlorine %, etc.

A basic semi-automatic unit with 500–1000 liters/hour capacity can be set up with ?15–25 lakhs. A medium-scale unit may require ?50 lakh to ?1 crore, depending on automation level and storage facilities.]
