Brutto: My first job in the lubricants industry was in 1980 working with the Penreco division of Pennzoil Products Co. I formulated industrial and automotive greases and managed the environmental and safety compliance activities for our production facility. It was a challenging, multifaceted job that was also very rewarding. I also attended my first STLE Chicago Section meeting that same year, ...

The allergenicity of methyldibromo glutaronitrile (MD BGN) (1,2-dibromo-2,4-dicyanobutane) is well recognized, both in occupational and in non-occupational settings (1). Used as a preservative, alone or in combination with phenoxyethanol (Euxyl K 400), in metalworking fluids, cosmetics, adhesives, and moist toilet tissues, it was identified as an increasingly important allergen soon after its l...

Abstract Oil-in-water (O/W) emulsions are water-based lubricants and used as fire-resistant hydraulic fluids metalworking (MWFs) in industry. The (elasto-)hydrodynamic film-forming properties of O/W have been studied extensively literature. Typical elastohydrodynamic lubrication (EHL) behaviors revealed at low rolling speeds followed by a starved EHL regime elevated speeds. These self-prepared ...

This is part of a series of review articles on formaldehyde-releasers and their relationship to formaldehyde contact allergy. Formaldehyde-releasers used in metalworking fluids (MWF) and a group of releasers not presented in previous articles are discussed. Here, in Part 1 of the article, there is a short overview of the composition and functions of MWF, the function of biocides in them, and ad...

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...

Metalworking fluids (MWFs) are widely used in machining process to improve its performance and product quality. It acts as a coolant and lubricant to reduce heat between the contact of two surfaces. However, commercial MWFs used in the industry were usually from petroleum-based oil which is toxic to the environment, difficult to dispose and caused significant health. Therefore, it is essential ...
