In this research we experimented with a new and rapid way of analyzing wood. Near Infrared (NIR) spectroscopy together with multivariate analysis is becoming a widely used technique in the field of forest products especially for property determination and is already firmly established in the pulp and paper industry. This method is ideal for the chemical analysis of wood, and therefore preservat...

Presence of a preservative in an ocular medication has often been considered a culprit in damaging the epithelium. However, the inclusion of a preservative is equally necessary, especially in multiple-dose containers, in order to protect against dangerous organisms accidentally gaining access during instillation. Benzalkonium chloride (BAK), chlorobutanol, chlorhexidine acetate (CHA), and pheny...

Preservatives are chemicals that are added to products that contain an aqueous phase. These include cosmetics, topical medications, household products, foods, and industrial products such as glues, paints, dyes, metalworking fluids, and spin finishes. They are biocidal or biostatic, inhibiting the overgrowth of micro-organisms and protecting and retarding the chemical degradation of the product...

The work aimed at estimating intake of food containing permissible preservatives. The data was comprised of food samples from 14 poviats of Podlaskie voivodeship taken to detect presence of preservatives (sodium nitrate, nitrite, benzoic acid and its salt, sorbic acid and its salt). The samples were collected between 2004 and 2007 by food inspection agency. Data concerning consumption of food p...

The purpose of this study is to develop and improve oral liquids formulations of sildenafil citrate for paediatric use. Four different formulations were developed, which are as follows: two aqueous solutions of sildenafil citrate (2.5 mg/mL), with or without preservatives, and two other solutions of sildenafil in simple syrup (1.25 mg/mL), with or without preservatives. All of the formulations ...
