What is Calcium Hydroxide (Lime)?
Calcium Hydroxide, commonly known as slaked lime, hydrated lime, or lime powder, is a fine white powder with the chemical formula Ca(OH)₂. It is produced by hydrating quicklime (calcium oxide), resulting in a strong alkali that is widely used across construction, agriculture, water treatment, cosmetic, food processing, and chemical industries.
With its alkaline pH, high reactivity, and excellent neutralizing power, calcium hydroxide is a multifunctional raw material known for stabilizing, disinfecting, binding, and softening.
✅ Applications of Calcium Hydroxide (Lime):
-
Construction Industry
Used in mortar, plaster, whitewash, and cement mixtures to enhance binding, water resistance, and durability of construction materials. -
Water Treatment
Acts as a pH adjuster and flocculant for removing heavy metals, bacteria, and hardness from industrial and drinking water. -
Cosmetic & Personal Care
Used in controlled amounts in depilatory creams, face masks, and hair relaxers for its pH-raising and cleansing properties. -
Agriculture & Soil Conditioning
Neutralizes acidic soils and provides essential calcium for plant nutrition, promoting better crop yield. -
Chemical Manufacturing
Used as a precursor in calcium salt production, plastic stabilizers, and various organic/inorganic syntheses. -
Food Processing (Regulated Use)
In food-grade quality, it’s used as a firming agent, acidity regulator, and in the nixtamalization of corn.

✅ FAQs:
Q1. What is the difference between quicklime and slaked lime?
A: Quicklime is calcium oxide (CaO), while slaked lime is calcium hydroxide (Ca(OH)₂). Slaked lime is safer and ready-to-use in most applications.
Q2. Can calcium hydroxide be used in cosmetics?
A: Yes, in controlled formulations like face packs and depilatory creams. It raises pH and helps remove unwanted residues.
Q3. Is this product food-grade?
A: Our standard product is industrial-grade. For food-grade requirements, please contact us separately.
Q4. Can it be used for soil pH correction?
A: Absolutely. It helps neutralize acidic soils and provides essential calcium for plant growth.
Q5. Is it suitable for water softening?
A: Yes, calcium hydroxide is commonly used in softening hard water and neutralizing acidic wastewater.
