Examples of professional applications in various industries:

• Chemical industry - Production of soaps and detergents: Sodium hydroxide is used as a key ingredient in the production of soaps and detergents. It serves as a strong alkaline agent that saponifies fats, thus forming soaps and other cleaning products.
• Paper industry - Wood pulping for paper production: Sodium hydroxide is used in the kraft process to produce pulp from wood. It helps remove lignin and release the cellulose fibers needed for paper production.
• Oil industry - Cleaning and refining of petroleum products: Sodium hydroxide is used in the oil industry to remove sulfur compounds and clean petroleum products. It helps eliminate unwanted impurities and improve the quality of the final products.
• Textile industry - Textile processing and dyeing: Sodium hydroxide is used in the textile industry to clean and refine fibers such as cotton. It is also used in dyeing processes to improve dye uptake and achieve vibrant, durable colors.
• Food industry - Cocoa and chocolate production: Sodium hydroxide is used in the food industry for cocoa processing. It is employed in a process known as 'Dutching' to regulate pH, enhance flavor, and improve the solubility of cocoa powder.

Recommended storage conditions:

1. Store in a dry and ventilated place.
2. Protect from moisture and sudden temperature changes.
3. Keep away from ignition sources and sparks.
4. Store in sealed containers or bags to prevent dusting.
5. Keep away from chemical substances that may contaminate it.

Sodium hydroxide (caustic soda) should be stored in a dry, well-ventilated area away from flammable materials and reactive substances. It should be kept in tightly closed original containers to avoid moisture and contamination. Storage temperature should not exceed 40°C. Proper labeling of containers according to chemical substance regulations is also required.
