Rinsing agent

Pharmacokinetic factors that affect substantivity of rinsing agents. 

As an oral rinsing agent, to date chlorhexidine has not been reported to produce any toxic systemic effects. Since chlorhexidine is poorly absorbed in the oral cavity and gastrointestinal tract, little if any enters the bloodstream. A summary of chlorhexidine oral rinses is given in Table 42.1. 

PerioGard, Peridex, Listerine, and Plax are trade name examples other similar generic rinsing agents are commercially available. Essential oils contain eucalyptol, methyl salicylate, thymol, and menthol. 

A mixture of essential oils consisting of thymol 0.06%, eucalyptol 0.09%, methyl salicylate 0.06%, and menthol 0.04% in an alcohol-based vehicle (26.9%) provides the plaque-inhibiting properties of rinsing agents such as Listerine.

The heading production of chemical products includes the conversion of allyl alcohol to glycerine with hydrogen peroxide, the production of epoxy-compounds such as epoxy soya oil (plasticizer for PVC) and organic peroxides (e.g. methyl-ethyl-ketone-peroxide, dibenzoylperoxide), which are used as free radical initiators in polymerization processes. The production of amine oxides such as lauryl-dimethyl-amine-oxide with hydrogen peroxide (used as a rinsing agent in dishwashers) is also included.

In many cases, glass and even porcelain bondings are carried out as repairs in households. In such cases, it has to be pointed out that, compared to the two-component reactive adhesives, in particular epoxides, cyanoacrylates show only a limited bond strength in the face of high temperature and humidity stress in connection with rinsing agents in the cleaning equipment. 

Several researches have justified that surfactant solutions can not only use as rinsing agents to effectively desorbing hydrophobic organic pollutants from soil (Edwards D.A. et al., 1994 Liu. Z., 1991 Kile D.E. and Chiou C.T., 1988), but also act as catalysts in photochemical decay reaction of chlorinated organic compounds (Chu W.

Referring to Figure 14.8.16, a cosolvent process operation can be summarized as follows. Printed circuit boards containing flux residues are immersed into the boil sump, which contains a mixture of cosolvent and fluorochemical rinsing agent, typically about equal volumes of each. After being cleaned in the boil sump, the substitutes are immersed in the rinse sump, which contains nearly 100% fluorochemical. 

The primary function of the rinse sump is to remove the fluorochemicaFcosolvent mixture and the soil dissolved in it. Following immersion in the rinse liquid, the parts are moved into the vapor phase for a final rinse with pure fluorochemical vapor. Finally, the parts are lifted into the freeboard zone, where any remaining fluorochemical rinsing agent evaporates from the parts and returns to the sump by condensation from eooling eoils. At this point, the cleaning cycle is complete and the parts are elean and dry. 

The other solvent is a rinsing agent, called the RA. Hie RA is likely also to fulfill the drying requirement noted above.
