CarboCore supplies hydrated lime for water treatment, construction, agriculture, and industrial processing applications.
Hydrated lime begins with geology, but its value is proven in production. Egypt's hydrated lime starts as high-calcium limestone, burned into quicklime and then slaked with controlled water to form a fine, dry calcium hydroxide powder. Origin alone does not decide performance. Available lime, fineness, moisture and whiteness do. That is where every CarboCore order begins.
INDUSTRIAL APPLICATIONS
Applications are indicative and subject to the selected grade’s chemical composition, particle-size distribution, surface treatment and processing characteristics. CarboCore’s technical team supports customers in selecting the appropriate grade for their formulation and manufacturing process.
Food, feed, pharmaceutical, cosmetic, medical and potable-water applications require separately evaluated and approved grades. Compliance should not be claimed unless the relevant certification and regulatory documentation are available.

Hydrated lime causes serious eye damage and skin irritation. Handle with eye, skin and dust protection as described in the SDS.
Values are typical reference data for Egyptian hydrated lime supplied by CarboCore and are intended for buyer screening. Final specifications, fineness and suitability are confirmed per grade, application and shipment lot on the certificate of analysis. Samples are available on request.
The final specification should also establish:
Reported with a clear basis — as CaO equivalent or Ca(OH)₂.
To assess carbonation of the material.
Maximum agreed for storage and processing.
Particle-size distribution and sieve-residue limits.
With the measurement method stated.
Request the Technical Data Sheet (TDS), Safety Data Sheet (SDS), and batch-specific Certificate of Analysis (COA).
Technical approval should confirm the selected grade, analytical methods, acceptance limits, and suitability for the intended process. Drinking-water and food-related applications require separately verified grades and relevant approvals.
