THE STORY OF CALCIUM HYDROXIDE

Calcium Hydroxide: The Strong Alkaline pH Adjuster & Processing Agent

Calcium Hydroxide (Ca(OH)₂), commonly known as slaked lime, is a high-alkalinity inorganic compound used in cosmetics, pharmaceuticals, and industrial formulations as a pH regulator, buffering agent, and processing chemical. It plays a key role in depilatory creams, hair relaxers, dental products, and traditional skincare systems.

Created by Hydrating Quicklime for High-Purity Fine Powder

Calcium Hydroxide is manufactured by adding purified water to calcium oxide (quicklime), followed by drying, micronizing, and sieving to achieve consistent cosmetic-grade texture and purity. TRCkem supplies high-whiteness, low-impurity material suitable for regulated pH-controlled applications.

Neutralize. Process. Control pH.

Key uses in personal-care and pharma formulations:
✅ pH adjuster / alkalizing agent
✅ Used in hair relaxers & depilatory creams to soften keratin bonds
✅ Acts as a buffering base in dental care preparations (e.g., root canal pastes)
✅ Supports emulsification and product stabilization in traditional cold-process creams
✅ Used in some herbal / Ayurvedic paste formulas as a processing medium

Highly Alkaline – Strict Handling & Regulatory Limits Required

• Typical use level: <1% in finished cosmetic formulas (higher only in regulated depilatory/relaxer systems)
• Strongly alkaline (pH ~12.4 in 1% solution) → must be neutralized or safely buffered
• Can cause irritation if used incorrectly — requires PPE during handling
• Allowed in specific product categories under EU, FDA, and BIS regulations, banned in leave-on skincare
• Store sealed, dry, and away from acids or moisture exposure
