  • Publication number: 20090017243
    Abstract: Thermally formed thermoplastic articles can be protected from stress cracking in the presence of stress cracking promoting compounds by forming a shaped article comprising a thermoplastic and a liquid hydrocarbon oil composition. We have found that the liquid hydrocarbon oil composition prevents the stress cracking promoting materials from interacting with the polymeric structure of the stressed container to prevent or inhibit stress cracking in such materials. The methods and compositions of the invention are particularly useful in preventing stress cracking in polyethylene terephthalate beverage containers during bottling operations during which the bottle is contacted with aqueous and non-aqueous materials such as cleaners and lubricants that can interact with the polyester to cause stress cracking particularly in the container base.

  • Patent number: 5871590
    Abstract: A touchless car wash composition, that can be made from a concentrate and diluted to use concentration using commonly available service water can comprise an ether amine or diamine in particular a fatty ether amine or diamine. The novel compositions are typically free of hydrocarbon solvents and silicone materials that are common in prior art compositions. The compositions are used in touchless car wash processes in which the materials are sprayed in the form of an aqueous dilute solution to remove soil from the vehicle surface. The aqueous compositions are self removing and very small amounts of the aqueous solutions remain to create water spotting on cleaned vehicle surfaces. The novel compositions of the invention can also contain a variety of other ingredients in a fully formulated system. Such ingredients include rapid dewatering of painted surfaces, improved cleanliness of glass and painted surfaces. A substantial reduction of water spotting and concentrates stability.

  • Patent number: 5683724
    Abstract: The invention is a process for preventing microbial growth in aqueous streams by applying a C.sub.2 -C.sub.12 percarboxylic acid or mixture of such acids to the aqueous stream and to an automated dispensing system for the percarboxylic acids based on a correlation between oxidation-reduction-potential and anti-microbial levels of the aqueous stream. Generally, the process of the invention is applicable to aqueous streams used in any number of applications such as the application of streams for the transport of food products, e.g. fruits or vegetables, into the processing environment and through the various steps of processing.
