ABSTRACT This study investigated the decomposition of Bronopol and its degradation products how they produce Nitrosamines in oral hygiene products. Based on this study Bronopol was degradable in oral hygiene products which are containing aqueous medium, higher pH values (4 to10) and which are presented in higher temperatures and then gives formaldehyde, and nitro compounds. These nitro compounds are acting as a nitrosating agent and react with secondary amines then give Nitrosamines in the products. The degradation study was done by using determination of mass by LCMS and determination of formaldehyde content by Head-Space GC. These studies strongly demonstrate the Bronopol was degradable in aqueous medium and give formaldehyde and nitro compounds. Bronopol was not acting itself as a nitrosating agent and its degradation products act as a nitrosating agent. The products which are containing the secondary amines and the nitrosating agent then the Nitrosamines are formed in that product. Keywords: Bronopol, Degradation, Nitrosamines, Formaldehyde, Oral hygiene products. INTRODUCTION Bronopol is an organic compound also called as a 2-bromo-2-nitropropane-1, 3- diol (Molecular formula: C(Br)(NO2)(CH2OH)2). In cosmetics Bronopol is used as an antibacterial preservative to prevent spoilage due to microbial contamination [1]. Bronopol structure was shown in fig1.

  • Cosmetic Ingredients/Material Prohibited/Restricted by FDA (14 Total, Through November, 2011)
    Cosmetic ingredients/material prohibited/restricted by FDA (14 total, through November, 2011). For the most part, FDA regulatory action to ban use of an ingredient in cosmetics means that ingredient is exempt from CIR review. In the case of Methylene Chloride, CIR=s safety assessment that preceded FDA=s regulation is now superceded. In the case of Tallow and tallow derivatives, the FDA identification of prohibited cattle material does not ban Tallow and tallow derivatives use in cosmetics. In the case of Trichloroethane, the EPA ban (except for essential uses) and the FDA determination of non-essential use appears to relate to aerosol cosmetic uses only. Ingredient No. CIR Conclusion FDA Regulation 1 Bithionol Exempt from CIR review Cosmetics containing bithionol.are deemed to be adulterated because of FDA under section 601(a) of the Federal Food, Drug, and Cosmetic regulation.

They are all known to be potential skin allergens that lead to contact dermatitis. Thus, the identification of these unsafe chemicals in cosmetic products is of high importance. In the present study, solid-phase extraction (SPE) based on HyperSep reversed-phase C8/benzene sulfonic acid ion exchanger (HyperSep C8/BSAIE) and Sep-Pak C18 sorbents, and ultra-high performance liquid chromatography/diode array detector (UHPLC/DAD) were optimized for the simultaneous determination of MI, MCI, MP,EP,PP and BP in cosmetic products. HyperSep C8/BSAIE and UHPLC/DAD with the eluting solvent mixture (acetonitrile/methanol, 2:1, v/v) and detection wavelength (255 nm) were found to be the optimal conditions, respectively.

CANDIDATE NAME: SARA PICON CAMACHO SIGNATURE: DATE: 20/ 05/2011 SUPERVISOR NAME: ANDREW P. SHINN SIGNATURE: DATE: 20/05/2011 III Sara Picón Camacho ABSTRACT The intensification of freshwater aquaculture worldwide has facilitated the propagation of the parasitic ciliate protozoan Ichthyophthirius multifiliis Fouquet, 1876 commonly known as “fish white spot” or “Ich”. Ichthyophthirius multifiliis infections lead to high mortalities, generating significant economic losses in most cultured freshwater fish species worldwide. Until recently, malachite green was the chemical treatment traditionally used to control I. multifiliis infections. Its reclassification as carcinogenic to humans and its subsequent ban for use in food fish has left the industry without any suitable treatments. Currently, in-bath formaldehyde and sodium chloride treatments are the most common option used in farm systems to control I. multifliis infections. Given their low efficacy, however, they are not considered as sustainable long–term options. There is, therefore, an urgent necessity to find efficacious alternatives for controlling I. multifliis infections. The general aim of this research project was to improve the management of I.

Quirk Dr. Ali Dhinojwala Committee Member Dean of the College Dr. Scott Collins Dr. Stephen Z.D. Cheng Committee Member Dean of the Graduate School Dr. Ali Dhinojwala Dr. George R. Newkome Committee Member Date Dr. Judit Puskas Committee Member Dr. Mark D. Soucek ii ABSTRACT Poly(vinyl chloride), PVC, is a particularly important commodity polymer that accounts for an annual world-wide production of 26 million tons. It is used frequently in the medical field as blood storage bags, endotracheal and dialysis tubing and intravenous catheters. Common plasticizers, namely di(2-ethylhexyl) phthalate (DEHP), are added to PVC to improve the processability and flexibility by lowering the glass transition temperature. However, most phthalate plasticizers are potential carcinogens. There has been extensive research on PVC with surface coatings to improve biocompatibility, surface crosslinking to create a barrier to the plasticizer leaching and surface grafting of hydrophilic polymers for both biocompatibility and reduced plasticizer migration. A novel surface grafting technique is the grafting of hydrophilic monomers by physisorbed free radical initiators. This modification method can be applied to PVC to attach vinyl hydrophilic monomers by the “grafting from” method.

    POLYMER ADDITIVES ANTIMICROBIAL POLYMER ADD-BRONOPOL Technical Datasheet Product Information: POLYMER ADD-BRONOPOL is an excellent preservative for both leaveon and rinse off products such as creams, lotions, shampoos, rinses, wipes and towelettes. It is synergistic with other preservatives such as Isothiazolinones, Parabens and Iodopropynyl Butylcarbamate (IPBC). It is poorly soluble in non-polar solvent but shows a high affinity for polar organic solvent. Chemical Name 2-BROMO-2-NITRO-1,3-PROPANEDIOL (BRONOPOL) Grade Name POLYMER ADD-BRONOPOL CAS No. 52-51-7 EINECS No. 200-143-0 Molecular Formula C3H6BrNO4 Synonyms 2-Bromo-2-nitro-1,3-propanediol 1,3-Propanediol, 2-bromo-2-nitro 2-Bromo-2-nitropropane-1,3-diol TEST SPECIFICATION METHOD Appearance Form: Crystalline Powder Visual Colour: White Purity 99 % Min. By HPLC Melting Range 126 - 131 °C Melting point apparatus (open capillary tube method) Moisture Content 0.5 % Max.
