About Calcium Hydroxide

We are supplying a comprehensive range of Calcium Hydroxide to our clients. It is an odourless white powder which is used in the industrial settings. It finds the application in construction, food processing, cosmetic and paper production. It is known by another name which is called as a pickling lime that is used during the pickling process to give pickels. Calcium Hydroxide is also applicable in food ingredient, pharmaceutical aid, dental products, toothpaste raw material and cosmetic raw material.

Calcium hydroxide is an odorless white powder. Its used in industrial settings, such as sewage treatment, paper production, construction, and food processing. It also has medical and dental uses.

It is used in cosmetics and detergent , cleaning industry as well.

Calcium hydroxide has several forms and names, including:

calcium dihydroxide
calcium hydrate
calcium(II) hydroxide
food-grade lime
hydrated lime
Lime
pickling lime
slack lime
slaked lime

Pickling and calcium hydroxide

Pickling lime is sometimes used during the pickling process to give pickels an extra crunch. Its a form of food-grade calcium hydroxide. Traditional canning recipes usually suggest soaking freshly sliced cucumbers or other vegetables in pickling lime for 10 to 24 hours before canning them. During this step, the calcium in pickling lime binds to pectin, making it firmer.

Today, many recipes recommend avoiding pickling lime. This is because pickling lime has been linked .

A number of recipes offer alternatives to keep your pickles crunchy. These include soaking vegetables in ice water for four to five hours before pickling or using pickling salt.

High Reactivity for Effective Application

Calcium Hydroxide reacts promptly with acids and carbon dioxide, making it particularly suitable for processes like water softening, flue gas treatment, or soil stabilization. Its alkaline nature and high reactivity also allow precise pH adjustment in chemical manufacturing or industrial wastewater treatment, ensuring efficient outcomes wherever reliable alkalinity is required.

Versatile Packaging and Secure Storage

Available in secure 25 kg or 50 kg HDPE bags and jumbo bags, Calcium Hydroxide's packaging options meet industrial demands for bulk volumes and safe handling. Proper storage in a cool, dry place with containers kept tightly closed helps maintain its effectiveness and extends its shelf life up to two years. This ensures consistent results during prolonged storage and use.

Ideal for Multiple Industrial and Food Grade Uses

Widely utilized in water treatment, construction, sugar refining, and as a food additive, this product meets both industrial and food grade requirements. Its high purity range (97-99%) and low moisture content (1%) make it suitable for sensitive processes where product quality is crucial for operational efficiency and safety.

FAQ's of Calcium Hydroxide:

Q: How should Calcium Hydroxide be stored to maintain its quality and shelf life?

A: Calcium Hydroxide should be kept in tightly closed HDPE or jumbo bags and stored in a cool, dry place. This prevents moisture uptake and preserves its chemical stability, ensuring a shelf life of up to two years.

Q: What industries can benefit from using Calcium Hydroxide?

A: Industries such as water treatment, construction, food processing, sugar refining, soil stabilization, and chemical manufacturing commonly utilize Calcium Hydroxide for its pH adjustment properties, reactivity, and versatility.

Q: When is it necessary to handle Calcium Hydroxide with care?

A: Care is crucial when handling Calcium Hydroxide as it causes skin and serious eye irritation. Personal protective equipment like gloves and eye protection should always be worn, particularly during transfer, mixing, or application processes.

Q: Where is Calcium Hydroxide most effective in application processes?

A: Calcium Hydroxide is highly effective in applications like water softening, flue gas desulfurization, pH adjustment in industrial waste, and soil stabilization. It is also useful in food and sugar processing when high purity is mandatory.

Q: What is the benefit of using Calcium Hydroxide with high purity and low moisture content?

A: High purity (97-99%) and a low moisture content (1%) ensure optimal reactivity and minimal contamination, making the product suitable for processes which demand high performance and consistent, reliable results.

Q: How should Calcium Hydroxide be handled in terms of compatibility with other chemicals?

A: It is incompatible with strong acids, ammonium salts, aluminum, and magnesium. Avoid mixing Calcium Hydroxide with these substances to prevent hazardous reactions or loss of product efficacy.
