Coated Calcium Carbonate

Coated Calcium Carbonate plays a vital role across multiple industries and everyday products. It is commonly used in toothpaste for its gentle abrasive properties that clean without harming enamel. In cosmetics, it enhances texture and clarity in powders, lotions, and creams. Industrially, it serves as a key ingredient in PVC pipe manufacturing and paper production. Its safe composition also makes it suitable for pharmaceutical tablet formulations.

Composition of Chemicals

Calcium carbonate (CaCO3) must be at least 98% pure for its intended uses in order to minimise contaminants.

Distribution of Particle Sizes
One important criterion for coated calcium carbonate is its particle size. A common median particle size is between 1 and 10 micrometres, and it is usually managed to satisfy certain specifications. In order to maximise characteristics like opacity, rheology, or surface polish in their goods, various sectors may need varying particle size distributions.

Surface Coating
The calcium carbonate coating has a vital function that varies according to its intended use. Stearic acid, oleic acid, and other organic coatings may improve calcium carbonate compatibility with other materials, increase dispersion, and reduce agglomeration.

Whiteness and Brightness
Brightness and Whiteness is another criteria for coated calcium carbonate. Since calcium carbonate is often employed as a white pigment in a variety of applications, its brightness and whiteness are crucial characteristics. Its efficacy as a pigment is guaranteed by the brightness, which usually surpasses 95% on the ISO brightness scale.

Characteristics of Calcium Carbonate Coated

Density in Bulk
Depending on the particular formulation and coating utilised, coated calcium carbonate’s bulk density might change. The manufacturer’s product design determines the typical values, which vary from 0.6 to 1.2 g/cm³.

Absorption of Oil
An important requirement for paint and coating applications is the oil absorption ability. It displays how much oil or resin a calcium carbonate is capable of absorbing. Usually, it is stated as grammes of oil for every 100 grammes of calcium carbonate.

Properties of Chemicals
For its intended uses, coated calcium carbonate should be highly chemically stable and inert to the majority of substances. Additionally, it should be low in moisture to enhance flowability and avoid clumping.

What’s the Use of Coated Calcium Carbonate?

Uses of coated calcium carbonate are yet another crucial detail regarding this product to be aware of. Because of its special qualities, coated calcium carbonate is important in many different sectors and everyday life. toothpaste formulas include calcium carbonate for use in everyday life.

This material is often found in toothpaste. Abrasive qualities are seen in coated calcium carbonate. As a result, it cleans the teeth of plaque and other stains. But it doesn’t damage tooth enamel or gums. Cosmetic powders, lotions, and creams also include this substance. In cosmetic products, coated calcium carbonate enhances clarity and texture.

Additionally, calcium carbonate is used in manufacturing. There are several industrial applications for calcium carbonate. It is one of the necessary raw ingredients in PVC pipe manufactures, for instance. Naturally, paper is also made from this substance. The human body does not suffer any negative effects from using coated calcium carbonate. Because of this, it is also evident in the way that certain pharmaceutical company tablets are formulated.
