USP Talc

USP talc meets the standards set by the United States Pharmacopeia (USP), which is a comprehensive book of quality standards for drugs, dietary supplements, and healthcare products. USP standards ensure the quality, purity, strength, and consistency of these products to protect public health.

USP talc is specifically used in pharmaceutical and medical applications. It is required to meet stringent criteria to ensure its safety for use in medicinal and healthcare products. Some of the key characteristics of USP talc include:


USP talc must be free from impurities, contaminants, heavy metals, and other substances that could be harmful to health.

Particle Size and Distribution:

The particle size and distribution of USP talc are controlled to ensure consistent performance and behavior in pharmaceutical formulations.


In some medical applications, especially those involving direct contact with the body (such as surgical gloves or medical devices), sterility might be a requirement for talc.

Absence of Harmful Compounds:

USP talc must be tested to ensure that it does not contain harmful elements like asbestos, which can be a concern in certain types of talc deposits.


USP talc should exhibit consistent properties from batch to batch, ensuring predictable and reliable results in pharmaceutical formulations.

Compliance with Regulatory Standards:

USP talc must adhere to the regulations and guidelines established by regulatory bodies, including the U.S. Food and Drug Administration (FDA).

Non-USP Talc

Non-USP talc is typically used in industrial applications where such stringent quality and purity requirements are not mandated. It may be used in products such as paints, coatings, plastics, ceramics, and rubber, where its primary functions are to improve texture, act as a filler, or provide other functional benefits.

While non-USP talc can still be of high quality, it is not certified for use in applications where USP standards are required.  Some of these applications include:

Industrial Grade Talc:

This category includes various grades of talc used in industrial applications. It can range from coarser grades used as fillers in plastics, rubber, and paints to finer grades used in ceramics, roofing materials, and other industrial processes.

Paper Grade Talc:

Talc is used in the paper industry to enhance printability, opacity, and brightness of paper products. The particle size and purity are important considerations for paper applications.

Ceramic Grade Talc:

Talc used in ceramics needs to have specific properties to enhance firing characteristics, strength, and texture. Different grades might be used in clay bodies and glazes.

Plastics Grade Talc:

Talc is added to plastics to improve mechanical properties and processability. Different grades are selected based on the desired balance of properties in the final plastic product.

Paints and Coatings Grade Talc:

Talc used in paints and coatings should have the right particle size distribution and chemical composition to provide the desired matte finish, anti-corrosive properties, and viscosity control.

Rubber Grade Talc:

Talc can be used as a filler in rubber products to improve dimensional stability, tensile strength, and resistance to heat and chemicals.

Electrical Grade Talc:

Talc with specific electrical insulating properties is used in electrical components and insulators.

Ingredient in Industrial Applications:

It is employed in the manufacture of lubricants, plasticizers, and surfactants, contributing to improved performance and durability of industrial products​​.

Component in Food Packaging:

Stearyl Alcohol can be used in food packaging materials to provide a moisture barrier and enhance the durability of the packaging​​.

Precipitated Calcium Carbonate

Precipitated Calcium Carbonate (PCC) is a specialized form of calcium carbonate that is produced through a chemical process rather than being naturally occurring like limestone or marble. PCC offers unique properties that make it highly useful in a variety of applications across industries. Here are some industrial applications of PCC:

Paper Industry:

PCC is extensively used in the paper industry as a filler and coating pigment. Its fine particle size and high brightness improve paper’s printability, opacity, and surface quality.

Paints and Coatings:

PCC is used in paints and coatings to enhance opacity, brightness, and rheological properties. It contributes to smoother finishes and better coverage.

Plastics Industry:

PCC is used as a functional filler and reinforcement agent in plastics and rubber compounds. It improves mechanical properties and processing characteristics.

Adhesives and Sealants:

PCC can be used in adhesives and sealants to improve viscosity, enhance filler loading, and modify properties.


PCC is used in pharmaceutical formulations as an excipient and binder due to its high purity and inertness.

Food and Beverages:

Food-grade PCC can be used as a calcium source and an anti-caking agent in food products.

Personal Care Products:

PCC is used in cosmetics, toothpaste, and personal care products for its texture-enhancing and abrasive properties.

Environmental Applications:

PCC can be used in environmental applications, such as water treatment, to remove impurities and adjust pH levels.

Airfloat Charcoal

Airfloat charcoal, often referred to as “airfloat” due to its fine, powdery consistency, is a type of high-quality charcoal ground to a fine powder. AG&P Mineral Purveyors offers hardwood airfloat charcoal.  Its consistency and efficiency underscore its versatility and utility across various fields such as:  


Used as a fuel component in fireworks and other pyrotechnic compositions due to its fine texture and consistent burn rate.
