This research aimed to develop biodegradable films from polymer blended film containg food preservatives. 1H-NMR and FTIR showed that the added preservativesmodified chemical structure, leading modified properties. Accordingly, these preservatives effectively enhanced functionality of maintained quality safety, thus improving safety.

Long-term use of topical drugs has clearly been shown to induce toxic immunopathological changes in the ocular surface. Lacunae exist in the knowledge regarding the respective roles of active compounds and preservatives. The preservatives used in topical multidose ophthalmic preparations are responsible for a considerable compromise of ocular surface. In chronic diseases like glaucoma where lon...

INTRODUCTION Preservatives are added to cosmetic, household cleaning, and other industrial products to prevent the growth of microorganisms. Unfortunately, exposure to these substances can cause sensitization. MATERIAL AND METHODS Between January and June 2015, we analyzed the ingredients of 2300 products commercially available in Spain to identify the frequency of a wide variety of preservat...

AIM The objective of this study was to understand the adaptive mechanisms in Enterobacter gergoviae which are involved in recurrent contaminations in cosmetic products that are incorporated with preservatives. METHODS AND RESULTS Bacterial strains from two backgrounds were examined for a profound understanding of the mechanisms of adaptation against preservatives. It included a series of Ent....

BACKGROUND Preservatives present in cosmetics and other industrial products can cause allergic contact dermatitis. The aim of the study was to assess the frequency of allergy to selected preservatives in consecutive patients examined due to contact dermatitis in the Nofer Institute of Occupational Medicine, Łódź, and to establish whether individuals sensitized to formaldehyde react simultaneous...

OBJECTIVE The aim of this study was to investigate the stability of fortified cefazolin sodium ophthalmic solutions (50 mg mL⁻¹) extemporaneously prepared in commercial artificial tears containing 2 different types of preservatives, namely the surfactants and oxidants. METHODS Fortified cefazolin sodium solutions were prepared by reconstituting cefazolin for injection with sterile water and f...

The unending needs and demands for chemical free preservatives in food industry are on the increase due to facts that diseases like cancer complications from oxidative stress have been linked xenobiotics we eat foods as preservatives. There is need safe means of preserving our without side effects why world bio-preservative all forms augment both nutritional properties shelf life products. Bio-...
