Caustic Soda Lye 48%

Caustic Soda Lye is a liquid solution of Sodium Hydroxide (NaOH) dissolved in water, usually at 50% concentration. It is a clear, colorless liquid known for its slippery, soapy feel and ability to dissolve protein. It is an exceptionally strong alkali (pH 13-14) that quickly dissolves organic matter. It is a highly corrosive, strong alkali. Lye or caustic soda (NaOH) is a highly corrosive colorless liquid used extensively for industrial processes, chemical manufacturing, soap making, drain cleaning & water treatment.

Applications of Caustic Soda Lye:

• Chemical Manufacturing & Saponification: It is essential for making soaps, detergents and various cleaners, acting as the key agent in saponification to convert fats and oils.

• Pulp & Paper Industry: It is used for pulping, wood fiber bleaching and dissolving cellulose, making it crucial for paper and cardboard production.

• Aluminum Production: It is used to refine bauxite ore through the Bayer process to produce alumina, a raw material for aluminum metal.

• Petroleum Refining & Energy: It removes acidic contaminants from sour crude oil and is used in the production of drilling muds and fuel cell manufacturing.

• Textiles: It is employed in the textile industry for scouring and mercerizing cotton to improve strength, dye uptake and finish.

• Household & Commercial Applications:

• Drain & Pipe Cleaners: A strong alkali commonly used in industrial and household drain cleaners to dissolve fats, oils and grease.

• Industrial Cleaning: It is used in food-grade facilities to clean machinery, remove organic waste and as a degreaser.

• Food Industry Processing:

• Peeling: It is used in low concentrations to remove skins from fruits and vegetables, such as potatoes and tomatoes.

• Food Treatment: It is used to remove bitterness from olives and in the preparation of pretzels to create a unique shiny, crisp crust.

• Environmental & Water Treatment:

• Water Treatment: It is used to raise the pH level of water to reduce corrosion in pipes and remove heavy metals from water supplies.

• Pharmaceuticals & Others:

• Pharmaceuticals: It is used in the production of medicines like aspirin and anticoagulants.

• Other: It is used in glass manufacturing, rubber processing and as a raw material for bleach manufacturing.
