FAQs of Purified Talc:

Q: How is Purified Talc processed to ensure pharmaceutical and food-grade standards?

A: Purified Talc is manufactured from high-quality natural talc ore using advanced processing techniques. It undergoes purification steps to remove impurities, reduce heavy metal content, and ensure compliance with pharmacopeial regulations. Rigorous testing ensures suitability for pharmaceutical, food, and cosmetic uses.

Q: What are the primary applications of Purified Talc?

A: This product serves as a pharmaceutical aid (e.g., excipient, tablet diluent, dusting powder), a cosmetic ingredient, and a food additive. Its fine particle size and high purity make it suitable for direct application in formulations across industries, including personal care and industrial processes.

Q: When should Purified Talc be used in a formulation?

A: Purified Talc should be incorporated when a high-purity, neutral, and inert magnesium silicate is neededsuch as for improving texture, consistency, or lubricity in tablets, cosmetics, or food products. Its application depends on the desired function, like moisture absorption or dilution.

Q: Where should Purified Talc be stored to maintain quality?

A: It is crucial to store Purified Talc in a cool, dry area away from moisture. This prevents caking and safeguards its microbial and chemical stability. The product is typically supplied in robust 25 kg HDPE bags, with customized packaging options to cater to specific storage and transportation requirements.

Q: What is the typical process for customizing Purified Talc particle size?

A: Upon request, the manufacturing process can be tailored to adjust the particle size between 45 microns and 90 microns. This customization ensures optimal performance for diverse applications, where texture and dispersion are critical factors.

Q: How does using Purified Talc benefit formulations in the pharmaceutical and food industries?

A: Purified Talc offers excellent oil absorption (3550 ml/100g), is insoluble in water, and is both tasteless and odorless. These properties enhance the stability, consistency, and sensory experience of pharmaceuticals and food products, while its purity protects against contamination and regulatory issues.
