1.Product Definition：

Calcium Acetate is the calcium salt of acetic acid and a multifunctional organic calcium compound. It exists in monohydrate and anhydrous forms. It is widely used as a calcium source, buffering agent and processing aid in food, pharmaceutical, agriculture and feed applications. Due to its good water solubility and stable chemical properties, Calcium Acetate is suitable for applications requiring calcium supplementation, pH regulation and formulation stability.

3.Application of Calcium Acetate :

（1）Food additives: Calcium acetate is widely used in the food industry as a sour flavouring agent and antimicrobial agent. In sour flavouring agent, it can increase the sourness of food and improve the taste. In terms of antimicrobial agent, calcium acetate can inhibit the growth of bacteria and moulds in food, and effectively extend the freshness period of food.

（2）Pharmaceutical industry: Calcium acetate is used as a raw material and additive in the pharmaceutical industry. Its common application is as a calcium supplement for the treatment of osteoporosis, rickets and other diseases caused by calcium deficiency. In addition, it is also used as a solvent for topical medicines and as a binder for pills.

（3）Agricultural applications: Calcium acetate has important applications in agriculture. It is widely used as fertiliser and soil conditioner. As a fertiliser, Calcium Acetate can provide plants with the required calcium elements and promote the growth and development of plants. As a soil conditioner, it can adjust the acidity and alkalinity of soil, improve soil texture and increase soil fertility.

（4）Other applications: In addition to the main applications mentioned above, calcium acetate has some other applications. In the textile industry, it is used as fixing agent for dyes and printing. In leather industry, it is used as auxiliary agent of dyes and acidity regulator. In the building materials industry, calcium acetate can be used as an additive to cement and gypsum to improve the strength and durability of the materials.

4.Quality Assurance

Healthy Chemical implements comprehensive quality control from raw material selection, reaction process, purification, drying and finished-product testing to ensure stable quality of Calcium Acetate for tech, food, feed and pharmaceutical applications.

4.1 Purity & Calcium Content Control

Some suppliers have insufficient raw material control or unstable production processes, resulting in fluctuations in calcium acetate purity and calcium content.

This may cause difficulties in formulation calculation, inconsistent product performance and batch-to-batch variation in downstream applications.

Healthy Chemical Solution

Healthy Chemical uses high-purity acetic acid and qualified calcium hydroxide as raw materials. Through precise reaction control and process optimization, the conversion efficiency is stabilized and the active calcium content remains consistent.

4.2 Moisture Control, Anti-Caking & Flowability Improvement

Anhydrous calcium acetate has strong hygroscopic characteristics. Exposure to moisture during storage or transportation may cause:

-Moisture absorption
-Powder agglomeration
-Reduced flowability
-Difficulties in automatic feeding and accurate dosing

Healthy Chemical Solution

Healthy Chemical applies fluidized-bed drying combined with low-temperature evaporation technology to effectively control residual moisture.

Moisture content is strictly determined by Karl‑Fischer titration method. This method is selected because Unlike conventional oven drying, Karl Fischer titration reacts specifically with free water at room temperature without heating the sample — so it accurately measures total moisture, including water of crystallization, without losing volatile components. This method ensures more reliable and precise results.

Double-layer moisture-proof packaging is used to improve storage stability and reduce caking risks during transportation.

4.3 Water-Insoluble Matter & Solution Clarity Control

Improper production processes may introduce insoluble residues, causing calcium acetate solutions to appear:

-Turbid
-Yellowish
-Containing visible suspended particles

This may affect applications requiring high solution clarity, such as liquid food formulations and compound systems.

Healthy Chemical Solution

Healthy Chemical adopts an acetic acid–calcium hydroxide synthesis route combined with two-stage deep filtration technology to effectively remove insoluble impurities and improve solution clarity.

5. Storage:

Store in a cool, dry and well‑ventilated warehouse. Keep away from heat sources and direct sunlight.
Anhydrous calcium acetate is hygroscopic. Keep packages tightly sealed to avoid moisture absorption and caking. Do not expose the product to humid air.
Store separately from toxic, odorous and contaminating materials.
Shelf‑life: 24 months under recommended storage conditions.

FAQ:

Q1: Can calcium acetate be used in agriculture?
A: Yes. Calcium acetate can be applied in pesticides and fertilizers as a calcium source to supply bio‑available calcium for crops.

Q2: What are the side‑effects of calcium acetate?
A: As a food additive, occasional side‑effects include belching and constipation for a small number of people. For individuals with hypercalcemia or renal insufficiency, it may trigger rebound increase of gastric‑acid secretion. No adverse effects will occur for general population under legal dosage.

Q3: What is the pharmaceutical function of calcium acetate?
A: In pharmacy, calcium acetate acts as a phosphate binder for patients with chronic kidney disease to bind intestinal phosphorus and reduce serum phosphorus level. It is also used as raw material for calcium‑supplement preparations.

Q4: How is the water‑solubility of calcium acetate?
A: Calcium acetate is soluble in water. Thanks to our two‑stage deep‑filtration process, our product dissolves fast and delivers clear aqueous solution with minimal sediment.

Q5: What method is used to test the moisture of calcium acetate?
A: Moisture content is strictly determined by Karl‑Fischer titration method. This method is selected because Unlike conventional oven drying, Karl Fischer titration reacts specifically with free water at room temperature without heating the sample — so it accurately measures total moisture, including water of crystallization, without losing volatile components. This method ensures more reliable and precise results.
