2. What is Calcium Formate used for?

Calcium Formate 98 percent is a highly efficient chemical compound with numerous industrial applications. Its primary applications and strengths are as follows:

• Calcium formate 98 percent is used as a preservative in animal feed. It reduces the pH of the feed, which inhibits the growth of germs and extends the feed's shelf life.
• It inhibits the growth of bacteria and fungus.
• As it improves the penetration of chrome into the leather, it is used as a masking agent in chrome tanning of leather.
• Calcium formate is frequently used as a replacement for formic acid in the pickling process.
• It can also be used as a cement and grout additive. It gives the final product desired qualities. 
• It aids in increasing hardness and reducing setting time. 
• It keeps metal substrates from corroding in cement or grout
• It works wonders in preventing efflorescence.
• It works wonders in preventing efflorescence.
• In drywall, Calcium formate acts as a fire retardant.
• Its mixtures with urea are very effective defrosters. These reduces the corrosion of steel and cement surfaces.

3. What is the Chemical Formula of Calcium Formate?

The chemical formula of Calcium formate is Ca(HCOO)2 or C2H2CaO4.

4. Is Calcium Formate harmful to life?

Pure Calcium formate powder causes severe eye discomfort but no skin irritation. Inhaling powder might be hazardous. Liquids containing high Calcium formate concentrations induce serious gastrointestinal lesions when consumed.

5. Where is Calcium Formate found? What does Calcium Formate look like?

Calcium formate can be found in nature, most notably in bee and ant venom. In an aqueous solution, calcium formate is synthesised by reacting calcium hydroxide with formaldehyde in the presence of hydrogen peroxide or calcium peroxide with formaldehyde.

Calcium formate 98 percent appears as white to yellow crystals or crystalline powder.

6. What are the Hazardous effects of Calcium Formate?

When heated, calcium formate decomposes into combustible hydrogen and unpleasant gases (calcium oxalate, carbonate, and oxide) that can cause significant eye injury.

Furthermore, it reacts violently with strong oxidants.

7. What are precautionary measures necessary to be taken to handle Calcium Formate?

To minimize undesired outcomes, this substance must be stored and disposed of properly. When working with this chemical, it is important to follow safe industrial hygiene standards and to always wear personal protection equipment. Furthermore, while working in an atmosphere with Calcium formate dust, wearing a mask, gloves, and wearing a particulate filter respirator is recommended.

Precaution measures of Calcium formate

8. What will happen if Calcium Formate is heated?

When Calcium formate is heated to a high temperature, formaldehyde is formed. It's a colorless, pungent-smelling gas that's used to create building materials and a variety of household items.

9. Is Calcium Formate a soluble compound?

It is entirely soluble in water and slightly soluble in methanol, but it is insoluble in ethanol.

12. What is the PH of Calcium Formate?

The pH of this compound ranges from 5 to 8. 

13. Is Calcium Formate an electrolyte compound?

Calcium formate is an electrolytic compound that breaks down into its constituent ions in polar solvents.

14. Can Calcium Formate go down the drain?

Calcium formate, despite being biodegradable, should be kept away from drains, surfaces, and groundwater. This chemical and its container must be disposed of as hazardous waste according to the regulation.

15. What is the difference between Calcium Formate and Calcium carbonate?

These two substances have a lot in common, yet they also have a lot of differences. Calcium formate is the calcium salt of formic acid with the most industrial use, whereas calcium carbonate is the calcium salt with the most therapeutic applications.

3.1.1. Study 1 &#; Totally mixed ration

In the first study, a totally mixed ration (TMR) was prepared with 52% grass silage, 37% corn silage, 7.6% crimped wheat, 2.9% protein feed, 0.3% minerals and 0.25% salt. The dry matter (DM) content was approx. 43%. Three representative samples of the TMR were collected at study start to determine DM content, pH, and yeasts, moulds and total aerobic counts. The TMR was either left untreated (control, six replicates (350 g fresh matter (FM) each, in test tubes of 1,300 mL)) or treated with 3.0 g calcium formate/kg fresh TMR (six replicates). These samples were exposed to an aerobic environment (20 ± 1°C ambient temperature and 60&#;70% relative humidity) while their core temperatures were monitored. The lower end of the tubes was covered with an autoclaved, woven fabric to allow air to pass through. Sample temperatures were recorded every 2 h for a period of 5.3 days. Three replicates each were removed and analysed for pH, yeasts, moulds and total aerobic counts when the control samples went 5°C above the ambient temperature (T1). The remaining samples were analysed when the treated TMR reached the same temperature difference (T2).

The data were analysed statistically using a one&#;way ANOVA. Significance was set a p < 0.05.

At T1, treated samples, compared to the control, showed a significantly lower pH values (4.34 vs. 4.45), significantly lower counts for yeasts (6.35 vs. 7.50 log CFU/g) and total aerobic counts (6.63 vs. 7.59 log CFU/g). At T2, the differences in pH became more marked (4.59 vs. 6.12) and remained significant for yeast count (7.97 vs. 8.43 log CFU/g) and total aerobic counts (7.91 vs. 8.66 log CFU/g). T2 was reached 1.8 days after the T1.

3.1.2. Study 2 &#; Beet pulp

In the second study, that followed the same protocol described for Study 1, beet pulp (DM 27.5%) samples (660 g fresh matter (FM) each, in test tubes of 1,300 mL) were analysed for aerobic stability and DM content, pH, and yeast, moulds and total aerobic counts.

At T1, treated samples, compared to the control, showed a significantly lower pH values (3.66 vs. 3.95), significantly lower counts for yeasts (5.06 vs. 7.26 log CFU/g) and total aerobic bacteria (6.73 vs. 8.53 log CFU/g). At T2, that was reached 1.9 days after the T1, only yeasts counts were different between the treated and the control samples (6.79 vs. 7.88 log CFU/g, respectively).

3.1.3. Study 3 &#; Distiller's grains

Distiller's grains as a high moisture feed ingredient (8.2% DM), was taken for the third study. Distiller's grains were mixed with Ca&#;formate at 0 or 3.0 g/kg fresh matter. Twelve test tubes (500 mL volume, filled with 250 mL distiller's grains) for each treatment were stored at ambient temperature (20 ± 2°C). Once a day, samples were mixed manually for approximately 10 min to homogenize and to increase the aeration intensity. Sample temperatures were recorded every 2 h. Three tubes per treatment were removed and analysed for pH, yeast, mould and total aerobic count after 17, 24, 33 and 40 days (T1, T2, T3 and T4).

No differences were observed along the study in aerobic stability and in pH between the control and the Ca&#;formate treated distiller's grains. At all the sampling times the treated samples, compared to the control, showed a significantly lower counts for yeasts (T1: < 1.70 vs. 7.11 log CFU/g, T2: 2.87 vs. 6.61 log CFU/g, T3: 4.45 vs. 7.19 log CFU/g, T4: 2.39 vs. 6.97 log CFU/g). Total aerobic bacteria count was affected only at T4 (9.38 vs. 9.04 log CFU/g in treated and control, respectively), as well as moulds count (4.16 vs. < 1.70 log CFU/g in treated and control, respectively).
