Hazard Classes and Categories

Skin Irrit. 2 (53%) Eye Irrit. 2 (53%)

Pharmaceutical Lubricant

A hydrophilic and inert lubricant used in capsule and tablet formulations at 0.5–2.0% w/w concentration to reduce friction, prevent adhesion to punches, and improve tablet hardness and disintegration compared to metallic stearates

Food Additive

A versatile dough conditioner and stabilizing agent used in yeast-raised baked goods, dehydrated potatoes, and processed cereals to improve texture, volume, and crumb structure

Anti-adherent

A functional excipient that improves the flowability and compressibility of powders while reducing sticking during the compression of solid dosage forms

Coating Agent

A specialized additive used in tablet coatings to improve appearance, taste, and stability while reducing film coating time due to its hydrophilic nature.
