Shelf-life of a 2.5% sodium hypochlorite solution as determined by Arrhenius equation.
Accelerated stability tests are indicated to assess, within a short time, the degree of chemical degradation that may affect an active substance, either alone or in a formula, under normal storage conditions. This method is based on increased stress conditions to accelerate the rate of chemical degradation. Based on the equation of the straight line obtained as a function of the reaction order ...
متن کاملShelf life, dissolving action, and antibacterial activity of a neutralized 2.5% sodium hypochlorite solution.
OBJECTIVES The aim was to evaluate the shelf life and the dissolving and antibacterial properties of a neutralized 2.5% NaOCl solution. STUDY DESIGN The loss of available chlorine and the pH of the neutralized 2.5% NaOCl solution were recorded to determine its shelf life. The dissolving action on bovine dental pulp was assessed measuring weight loss, pH variation, and decrease in available ch...
متن کاملThe shelf-life of sodium hypochlorite irrigating solutions.
BACKGROUND Sodium hypochlorite (bleach) solutions are widely used as irrigants in endodontics. Their tendency to deteriorate is worsened by environmental influences which could cause loss of available chlorine content. METHODS This study measured the loss of available chlorine concentration in a range of sodium hypochlorite solutions under conditions which mimic clinical usage and storage. Do...
متن کاملANALYSIS OF DEXAMETHASONE SODIUM PHOSPHATE INJECTION AND OPHTHALMIC SOLUTION BY HPLC, KINETIC INTERPRETATION AND DETERMINATION OF SHELF LIFE
The use of accelerated temperature stability studies using the Arrhenius relationship is routine for estimating the stability of a drug at room temperature. Therefore, the acceleration method is used to determine the expiration date of dexamethasone aqueous formulation manufactured in Iran. A high-performance liquid chromatography (HPLC) method utilizing ultraviolet (UV) detection for dexa...
متن کاملBiological properties of a neutralized 2.5% sodium hypochlorite solution.
OBJECTIVES The objective of this study was to evaluate the influence of neutralizing a 2.5% NaOCl solution on its cytotoxicity, genotoxicity, and tissue-dissolving potential. STUDY DESIGN The cytotoxicity and the genotoxicity of Dakin, a 2.5% NaOCl solution, and a neutralized 2.5% NaOCl solution were assessed according to ISO 10993 standards. The weight of palatal mucosa samples placed in neu...
