12 Percent Sodium Hydroxide Concentrate in Heavy Duty Industrial Cleaning Formulations, offered under CAS number 1310-73-2, is a high-purity, industrial-grade sodium hydroxide solution designed for demanding cleaning and manufacturing applications. This product is typically employed where precise alkali strength and consistent reactivity are essential for process reliability and product quality. Featuring an assay purity of 12% sodium hydroxide in aqueous solution, it supports a broad spectrum of chemical cleaning, surface preparation, and synthetic workflows across industrial sectors.
On the molecular level, sodium hydroxide is represented by the formula NaOH, with a molecular weight of approximately 39.997 g/mol. As a strong inorganic base, it possesses a straightforward structure but exhibits robust reactivity, characterized by its ability to rapidly neutralize acids and promote saponification of fats and oils. In its concentrated 12% form, this solution is particularly valued in heavy-duty cleaning for its ability to emulsify, dissolve, and remove a wide range of organic and inorganic contaminants. The product's physical attributes include a density of approximately 1.13 g/cm³ at 20°C, a notably high boiling point of around 100°C (as an aqueous solution), and a melting point that is below room temperature, given its liquid state. It displays a water-clear appearance and is fully miscible with water. The flash point is not applicable due to its water-based nature, and its negative logP indicates high hydrophilicity. Assay confirmation ensures minimum 12% NaOH, with residual water content corresponding to balance and tight control of impurity profile. The solution is shipped and supplied fully compliant with heavy-duty industrial and pharmaceutical grade requirements.
Within industry, 12 Percent Sodium Hydroxide Concentrate sees primary application in industrial cleaning formulations, where it is incorporated into cleaners used in sectors ranging from food processing and breweries to metal surface preparation and plant maintenance. It is exceptionally effective at breaking down heavy grease, carbon buildup, and proteinaceous residues, making it ideal for use in clean-in-place (CIP) systems and soak tanks where rapid, high-capacity throughput is necessary. Its robust base strength allows for efficient neutralization of acid contaminants and decontamination of processing equipment. Beyond cleaning, sodium hydroxide solutions are employed in the adjustment of process pH in continuous manufacturing environments, participating in titration and neutralization reactions that underpin flow chemistry processes. Additional recognized uses include chemical pulp and paper production, wastewater neutralization, and general-purpose chemical synthesis as a reliable inorganic base. Sodium hydroxide’s ability to facilitate ester hydrolysis, promote saponification, and act as a nucleophile further broadens its value in industrial manufacturing scenarios.
Packaging for this sodium hydroxide concentrate features sturdy 25 kg high-density polyethylene (HDPE) drums, each filled under a nitrogen-purged headspace to eliminate oxidative degradation and ensure product integrity during long-term storage and transport. To achieve optimal shelf life, the concentrate should be stored in sealed original containers at ambient temperature in a dry, well-ventilated area away from acids and incompatible materials. When stored under recommended conditions, the product maintains its specifications for at least 24 months post-manufacture. Certificate of Analysis (COA) documentation accompanies every shipment, providing batch-specific assurance of compliance, assay value, and physical characteristics as required for regulated use.
