Product Overview
Sodium Hydroxide, commonly referred to as caustic soda or lye, is a strong inorganic alkali widely used as a fundamental reagent across laboratory, industrial, and manufacturing applications.
In its solid form, sodium hydroxide appears as a white, odourless, hygroscopic material that readily absorbs moisture and carbon dioxide from the atmosphere. When dissolved in water, it forms a highly alkaline solution with substantial heat release, making it a powerful agent for pH control, chemical synthesis, and material processing.
Ausamics Sodium Hydroxide is supplied with consistent quality and purity, suitable for controlled laboratory use and technical applications.
