that the USDA do not intend publishing a final list of approved products. The situation has already caused widespread concern in the U.S.; those suppliers who are in the process of developing new products suitable for use in the food industry rightly claiming that they will now suffer a competitive disadvantage against established products as a result of no longer being able to claim USDA approvals, which contravenes the strict U.S. laws on competitive issues. This in turn could lead to suppliers of established products seeking higher prices, and could also stifle the development of newer products which may well be superior in terms of performance and in health and safety terms. Also, smaller companies could be unfairly disadvantaged if the costs of entry into the market are increased.


As a result, there has been some degree of activity to endeavour to establish a new body. One of the prime movers


has been ELGI, the European Lubricating Grease Institute. Greases are one of the major classes of compound which are often associated with incidental contact food machinery lubricants, and ELGI are currently evaluating the degree of support for establishing a replacement approval system.


Any individual or organisation wishing to become involved, or add general support, to setting up a new body is requested to contact the ELGI Secretariat, i.e.

New base fluids technology from ICI company for high performance, low environmental impact metalworking fluids


UNICHEMA PRIOLUBE SELF EMULSIFYING ESTERS


A range of advanced base fluids for metalworking lubricants has been developed that offer major benefits: these include extended fluid working life; greatly reduced consumption levels; the minimisation of the effects on fluids of water hardness and cheaper disposal and recycling costs. The significantly lower levels of usage also reduce environmental impact.


Unichema, a member of the ICI group, under the company's PRIOLUBE brand, is marketing this range of self-emulsifying esters (often called SEEs). Advanced multifunctionality is achieved as these esters are based upon a single compound that combines lubricity and emulsifying functions. Therefore the benefit of these advanced Priolube products is that the emulsifier and the base oil can never be separated.


Unichema has carried out a comparative field test of the self- emulsifying ester based metal working fluids. Over a two year period, the end user engineers have consistently found that they did not need to change the SEE fluids, whereas the commercial counterpart (mineral oil based) had to be emptied and renewed f ive times.


A problem with conventional metal working fluids is the formation of calcium soap deposits, which can be particularly troublesome in 'hard water' areas with high calcium levels. Self-emulsifying esters remove this problem as they are stable in hard water and do not foam in soft water, thus creating savings for blenders and users. Formulation and usage software to support new SEEs


Unichema has also developed tailored software to help blenders and formulators to calculate end users cost savings when using the self- emulsifying esters. In particular, this software gives a direct comparison between performance of the SEE based and conventional metal working fluids. Called SEEmulator, the program allows the calculation of key fluid management factors. These include the expected disposal volumes; concentrate consumption; total metalworking fluid system costs; relative cost savings of the SEE formulations; margin benefit to the blender and end user - all on an annual basis. The software is particularly appropriate where end users are using Total Fluid Management, as the software will also calculate the commercial benefits both to the fluids seller and buyer. Formulation meets wide user needs

The new product range consists of four emulsifying base fluids to meet a variety of metalworking applications from precision engineering through to aluminium and steel rolling mi lls : 3951 (transparent), 3952 (m i lky), 3953 (coarse milky) and 3955 (translucent). Unichema supports the market with worldwide techn ical service; these base flu ids are available to blenders and distributors .
